Redirect Chain Checker & Validator

A redirect chain checker and validator is an essential diagnostic system used by web developers and search engine optimization (SEO) professionals to trace the exact sequence of HTTP requests and responses that occur when a web browser or search engine crawler attempts to access a specific Uniform Resource Locator (URL). By systematically mapping out every intermediate jump a URL takes before arriving at its final destination, this validation process prevents critical losses in search engine rankings, eliminates infinite redirect loops, and drastically reduces page load latency. Understanding and mastering redirect validation empowers website owners to preserve digital authority, optimize server crawl budgets, and deliver seamless user experiences across complex web architectures.

What It Is and Why It Matters

A redirect chain occurs when a single URL request is forwarded multiple times through various intermediate web addresses before finally returning a successful webpage or an error message. In a perfect digital ecosystem, a user clicks a link or types a URL, and the server immediately responds with the exact content requested. However, as websites evolve, pages are deleted, domain names change, and security protocols upgrade from HTTP to HTTPS. To prevent users from hitting dead ends, webmasters implement redirects to seamlessly forward traffic from the old location to the new one. When these forwarding rules stack on top of each other—for example, URL A redirects to URL B, which redirects to URL C, which finally loads URL D—a redirect chain is born. A redirect chain checker and validator is the diagnostic mechanism that automatically follows this path, recording every server status code, measuring the time taken for each hop, and identifying the final destination.

The existence of redirect chains creates two massive, quantifiable problems for any digital property: search engine optimization degradation and severe performance latency. Search engines like Google operate using automated software known as crawlers or spiders. These crawlers are allocated a specific "crawl budget" for every website, representing the maximum number of pages the bot will request during a given timeframe. When a crawler encounters a redirect chain, it must expend valuable crawl budget processing each intermediate hop rather than discovering new, valuable content. Furthermore, search engines historically penalize long redirect chains by diluting the "link equity" or ranking power passed from the original URL to the final destination.

Beyond search engine mechanics, redirect chains severely degrade the human user experience by multiplying network latency. Every single jump in a redirect chain requires the user's browser to perform a new Domain Name System (DNS) lookup, establish a new Transmission Control Protocol (TCP) connection, negotiate a new Transport Layer Security (TLS) handshake, and wait for the server's Time to First Byte (TTFB). If a single hop takes 250 milliseconds, a chain of four redirects adds a full second of blank-screen waiting time for the user. In an era where e-commerce conversion rates drop by an average of 4.42% for every additional second of load time, allowing redirect chains to persist directly translates to lost revenue. Validating these chains ensures that digital architecture remains flat, efficient, and highly performant.

History and Origin

The concept of URL redirection is as old as the standardized web itself, originating with the formalization of the Hypertext Transfer Protocol (HTTP). When Sir Tim Berners-Lee and his team at CERN developed the foundational architecture of the World Wide Web in the early 1990s, they recognized that document locations would inevitably change as networks grew. In May 1996, the Internet Engineering Task Force (IETF) published Request for Comments (RFC) 1945, which formally defined HTTP/1.0. This seminal document introduced the 3xx class of status codes, specifically creating the 301 "Moved Permanently" and 302 "Moved Temporarily" directives. The intention was purely functional: to tell a rudimentary web browser where to find a relocated file. At this point in history, redirect chains were rare because websites were small, static, and manually coded.

The critical importance of monitoring and validating redirect chains emerged directly alongside the rise of modern search engines, specifically following the launch of Google in 1998. Google's foundational algorithm, PageRank, treated hyperlinks as votes of confidence. If a highly trusted website linked to a specific URL, that URL gained authority. Webmasters quickly realized that if they moved a page, they needed to use a 301 redirect to pass that accumulated PageRank to the new location. By the early 2000s, as websites transitioned to dynamic content management systems (CMS) like WordPress and Drupal, automatic redirection became commonplace. Unfortunately, these automated systems often created hidden, cascading rules. A user might change a URL slug, prompting the CMS to create a redirect. A year later, they might change it again, creating a second redirect pointing to the first.

By 2010, the web was undergoing a massive architectural shift. Websites were moving from non-www to www structures, and crucially, from insecure HTTP to secure HTTPS protocols. This transition created a perfect storm for redirect chains. A single request could easily bounce from http://example.com to http://www.example.com to https://www.example.com before finally reaching the intended page. Recognizing the massive strain this put on their infrastructure, Google officially announced that their Googlebot crawler would stop following redirects after a maximum of five consecutive hops. This hard limit transformed redirect chain validation from a niche technical curiosity into a mandatory requirement for digital survival. Consequently, the SEO software industry exploded with specialized tools designed specifically to map, measure, and validate these invisible server pathways.

How It Works — Step by Step

To understand how a redirect chain validator functions, one must understand the exact mechanical sequence of an HTTP network request. When a validation system queries a URL, it acts as a highly specialized, programmatic web browser. It initiates the process by parsing the target URL and extracting the domain name. The system queries a DNS server to resolve the domain name into an Internet Protocol (IP) address. Once the IP address is known, the validator initiates a TCP handshake with the destination server and, if the URL uses HTTPS, completes a TLS cryptographic handshake to secure the connection. The validator then transmits an HTTP GET request, asking the server to return the contents of the specified path.

If the requested URL has been moved, the server does not return the webpage's HTML. Instead, it returns an HTTP response header with a 3xx status code (such as 301 or 302) and a special header field called Location. The Location header contains the exact URL of the new destination. A standard web browser would silently and automatically follow this new URL, hiding the process from the user. However, a redirect validator intercepts this response, logs the 3xx status code, records the exact timestamp to measure latency, and logs the URL found in the Location header. The validator then treats this new URL as a brand-new request, repeating the entire DNS, TCP, TLS, and HTTP GET process from scratch. It utilizes a while loop in its programming architecture, continuing this cycle until the server finally returns a 200 OK status code (indicating success) or a 4xx/5xx status code (indicating an error).

The Latency Calculation Example

To illustrate the devastating impact of a redirect chain, we can mathematically model the latency incurred. Suppose a user on a mobile 4G network clicks a link to http://example.com/shoes. The network conditions dictate the following baseline latencies for a single request: DNS Lookup takes 50 milliseconds (ms), TCP Handshake takes 60 ms, TLS Negotiation takes 100 ms, and the server's Time to First Byte (TTFB) takes 90 ms.

For a single, direct request (no redirects), the total latency is the sum of these operations: Total Latency = DNS (50) + TCP (60) + TLS (100) + TTFB (90) = 300 ms.

Now, assume the server has a poorly configured redirect chain consisting of three hops: Hop 1: http://example.com/shoes redirects to https://example.com/shoes (HTTP to HTTPS). Hop 2: https://example.com/shoes redirects to https://www.example.com/shoes (Root to WWW). Hop 3: https://www.example.com/shoes redirects to https://www.example.com/footwear (Old product category to new category). Final Destination: https://www.example.com/footwear returns a 200 OK.

Because the domain or protocol changes slightly in these hops, the browser must often re-establish connections. Latency for Hop 1: 300 ms. Latency for Hop 2: 300 ms. Latency for Hop 3: 300 ms. Latency for Final Destination: 300 ms.

The total time spent merely negotiating the network before a single image or line of text is downloaded is: 300 ms × 4 = 1,200 ms (1.2 seconds). By validating and condensing this chain into a single direct redirect from http://example.com/shoes to https://www.example.com/footwear, the webmaster eliminates two unnecessary hops, saving 600 ms of pure network latency.

Key Concepts and Terminology

To master redirect validation, one must become fluent in the specific nomenclature of web architecture and network protocols. The foundation of this vocabulary is the HTTP Status Code, a three-digit integer returned by a server to indicate the result of a client's request. Status codes in the 200 range indicate success, the 400 range indicates client errors (like the famous 404 Not Found), and the 500 range indicates server errors. The 300 range is strictly reserved for redirection. The Location Header is the specific line of text within an HTTP 3xx response that explicitly dictates the new destination URL. Without a Location header, a redirect cannot function.

The User-Agent is a string of text sent by the client (browser or crawler) to identify its software, version, and operating system to the server. Validators often allow users to spoof or change their User-Agent to simulate how a server responds to Googlebot versus a standard iPhone Safari browser. Link Equity (colloquially known as "link juice") is an SEO concept representing the ranking authority passed from one page to another via hyperlinks. Redirects historically dilute this equity; minimizing chains preserves it. Crawl Budget refers to the finite number of requests a search engine bot is willing to make to your server in a given day; wasting this budget on redirect chains prevents the bot from indexing actual content.

A Redirect Loop is the most catastrophic variation of a redirect chain. This occurs when two or more URLs point to each other in an infinite cycle. For example, URL A redirects to URL B, and URL B redirects back to URL A. The validator or browser will bounce between the two indefinitely until it hits a hard-coded limit (usually 20 redirects in modern browsers) and throws an ERR_TOO_MANY_REDIRECTS error, completely breaking the user experience. Finally, Time to First Byte (TTFB) is the metric used to measure the responsiveness of a web server. It represents the time elapsed from the moment the client sends an HTTP request to the moment it receives the very first byte of data from the server's response. Redirect chains multiply TTFB exponentially.

Types, Variations, and Methods

Not all redirects are created equal, and understanding the nuances between different implementation methods is crucial for accurate validation. The most fundamental distinction lies between server-side redirects and client-side redirects. Server-side redirects occur entirely at the network infrastructure level before any HTML is downloaded. When a browser requests a URL, the server immediately intercepts the request via configuration files (like Apache's .htaccess or Nginx's nginx.conf) and issues a 3xx status code. This is the fastest, most secure, and most SEO-friendly method of redirection because it requires the least amount of computational overhead from the user's device.

Within server-side redirects, there are several distinct HTTP status codes, each communicating a different semantic meaning to search engines. The 301 Moved Permanently is the absolute gold standard for SEO. It explicitly tells search engines that the old URL is dead forever, and all link equity and historical ranking signals should be permanently transferred to the new destination. The 302 Found (traditionally "Moved Temporarily") tells search engines to forward the user but to keep the original URL indexed because the move is only short-term (e.g., redirecting users during a 48-hour site maintenance window). The 307 Temporary Redirect and 308 Permanent Redirect are modern equivalents introduced in HTTP/1.1 to solve technical ambiguities regarding how web forms (POST requests) are handled during a redirect, ensuring that form data isn't accidentally dropped when moving from an insecure to a secure connection.

Client-side redirects, conversely, are executed by the user's browser after the initial webpage has already been partially or fully downloaded. The most common form is the Meta Refresh, implemented via an HTML tag in the document's <head> section (e.g., <meta http-equiv="refresh" content="5;url=https://example.com/new">). This tells the browser to wait a specified number of seconds (in this case, 5) and then load the new URL. Another method is the JavaScript Redirect, where a script executes a command like window.location.href = "https://example.com/new";. Client-side redirects are generally considered poor practice for SEO. They are significantly slower because the user must download the HTML, parse it, and execute the code before the redirection even begins. Furthermore, some search engine crawlers struggle to execute JavaScript reliably, meaning a JavaScript redirect might be entirely invisible to Googlebot, creating an SEO black hole.

Real-World Examples and Applications

To fully grasp the utility of a redirect chain validator, we must examine a concrete, real-world scenario that frequently plagues enterprise-level websites. Consider a mid-sized e-commerce company, "TechGear," that was originally built in 2012. Their original website architecture used insecure HTTP and did not enforce the "www" subdomain. Their flagship product URL was http://techgear.com/laptops/gaming-pro. Over the next decade, the company went through several mandatory digital upgrades. First, they forced all traffic to the "www" subdomain to standardize their analytics. Two years later, they purchased an SSL certificate and forced all traffic to secure HTTPS. Finally, they completely revamped their product catalog structure, changing the category slug from /laptops/ to /computers/.

Because these changes were implemented years apart by different development teams, the server configuration files simply stacked the rules on top of one another. If an external technology blog linked to the original 2012 URL, a user clicking that link today would experience the following hidden journey:

1. The user requests: http://techgear.com/laptops/gaming-pro
2. Server rule 1 triggers (Add WWW). Server responds with 301 to: http://www.techgear.com/laptops/gaming-pro
3. The user's browser requests the new URL.
4. Server rule 2 triggers (Force HTTPS). Server responds with 301 to: https://www.techgear.com/laptops/gaming-pro
5. The user's browser requests the secure URL.
6. Server rule 3 triggers (Update category slug). Server responds with 301 to: https://www.techgear.com/computers/gaming-pro
7. The user's browser requests the final URL.
8. Server responds with 200 OK and delivers the HTML.

This is a classic three-hop redirect chain. If TechGear receives 50,000 visitors a month through old backlinks pointing to the 2012 URL, they are forcing 150,000 unnecessary server requests every single month. A redirect chain validator would expose this exact sequence. The application of this knowledge is simple but profoundly effective: the SEO team edits the server configuration to intercept the original http://techgear.com/laptops/gaming-pro URL and issue a single, direct 301 redirect straight to https://www.techgear.com/computers/gaming-pro. By collapsing the chain from three hops to one, TechGear instantly reclaims server bandwidth, improves the mobile load time by nearly a full second, and ensures that 100% of the historical link equity from the external technology blog flows directly to the modern product page.

Common Mistakes and Misconceptions

The landscape of URL redirection is rife with deeply entrenched myths and fundamental misunderstandings, even among seasoned web developers. The most pervasive misconception is the belief that because Google officially stated in 2016 that 30x redirects no longer lose PageRank, redirect chains are no longer an SEO issue. This is a dangerous oversimplification. While it is true that Google removed the historical 15% algorithmic penalty per redirect hop, this only applies to the raw calculation of link equity. It completely ignores the mechanics of the crawl budget. Googlebot operates on strict timing algorithms; if a server takes too long to respond due to multiple redirect hops, the bot will simply abandon the request and move on. Passing 100% of the link equity is entirely useless if the search engine refuses to wait long enough to actually index the final destination page.

Another incredibly common mistake is treating 301 and 302 redirects as interchangeable. Developers frequently use 302 (Temporary) redirects for permanent site migrations simply because 302 is the default setting in many programming frameworks and server software. When a 302 redirect is used for a permanent move, search engines become confused. They assume the old URL will return shortly, so they keep the old URL in their index and refuse to rank the new URL. This results in a catastrophic loss of organic traffic, as the new, updated page is essentially ignored by search engines for months while they wait for the "temporary" redirect to be removed. A redirect validator easily catches this error by explicitly flagging the HTTP status code of every hop.

A third major pitfall is ignoring internal link architecture after implementing redirects. Many webmasters believe that setting up a 301 redirect in the .htaccess file is the end of the job. They leave hundreds of internal links within their own website's navigation, footer, and blog posts pointing to the old, redirected URLs. While the server will successfully forward users who click these internal links, the webmaster has intentionally built a redirect chain into their own site architecture. Best practice dictates that a redirect is merely a safety net for external traffic; all internal links must be manually updated to point directly to the final 200 OK destination URL. Relying on redirects for internal navigation is a hallmark of amateur site management.

Best Practices and Expert Strategies

Professional SEOs and enterprise systems architects do not merely react to redirect chains; they implement proactive strategies to ensure they never form in the first place. The absolute golden rule of redirection is the "Maximum One Hop" policy. Every single redirect rule on a server must point directly to a final, 200-status URL. If a URL must be moved a second time, the original redirect rule must be located and updated to point to the newest destination, rather than simply chaining a new rule onto the old destination. This requires meticulous record-keeping, often managed through a centralized redirect mapping spreadsheet before any code is ever pushed to a live server.

Experts heavily rely on Regular Expressions (Regex) to manage redirects efficiently at scale. Instead of writing 10,000 individual redirect rules for a massive site migration, a developer can write a single line of Regex in an Nginx or Apache configuration file that dynamically catches patterns and forwards them. For example, a single Regex rule can ensure that any URL ending without a trailing slash (e.g., example.com/page) is instantly 301 redirected to the version with a trailing slash (example.com/page/). However, Regex is a double-edged sword; a single misplaced character can accidentally create an infinite redirect loop across the entire domain. Therefore, experts always test Regex rules in a localized staging environment using a redirect validator before deploying them to production.

Another advanced strategy involves the implementation of HTTP Strict Transport Security (HSTS). As discussed, one of the most common causes of redirect chains is the mandatory hop from insecure HTTP to secure HTTPS. HSTS is a powerful security header that a server sends to a browser, instructing the browser to never attempt to load the site via HTTP again. Once a user's browser receives the HSTS header, any future attempts to type http://example.com will be internally upgraded to https://example.com by the browser itself, before any network request is even sent. This completely eliminates the network latency of the HTTP-to-HTTPS redirect hop for returning visitors, representing a massive performance optimization.

Edge Cases, Limitations, and Pitfalls

While redirect chain validators are incredibly powerful tools, they operate within the constraints of complex, global network architectures, leading to several edge cases that can confound even experienced users. One of the most frustrating edge cases is the Geo-IP Redirect Loop. Many multinational corporations automatically redirect users based on their physical location (determined via their IP address). If a user in the UK attempts to visit example.com/us, the server detects their UK IP and forces a 302 redirect to example.com/uk. If a redirect validator is hosted on a server physically located in the United States, it will be completely blind to this UK-specific redirect. Conversely, if a UK-based validator attempts to check a specific US URL, it may get caught in an infinite loop if the server aggressively continually forces it back to the UK version. Validating geo-redirects requires a tool that allows the user to simulate requests from specific global proxy servers.

User-Agent Cloaking and Bot-Specific Redirects present another significant limitation. Some servers are configured to respond differently depending on who is asking. A server might serve a standard 200 OK webpage to a regular Chrome browser, but instantly issue a 301 redirect when it detects the "Googlebot" User-Agent. This is often done maliciously (a black-hat SEO tactic known as cloaking) or accidentally through poorly configured mobile redirects. If a webmaster uses a generic redirect validator, it will report that the URL is perfectly fine. The webmaster will remain entirely unaware that search engines are being chained and redirected elsewhere. Overcoming this pitfall requires utilizing a validator that allows for explicit User-Agent spoofing.

Finally, Content Delivery Network (CDN) and Browser Caching can create maddening "ghost" redirects. When a 301 Permanent Redirect is issued, modern browsers and CDNs (like Cloudflare or Fastly) cache that instruction aggressively. If a webmaster makes a mistake, creates a redirect loop, and then fixes the code on their origin server five minutes later, they may still experience the loop. The browser or CDN remembers the 301 directive and executes it locally without ever checking the origin server to see if the rule was updated. Developers often waste hours troubleshooting perfectly valid server code because they fail to realize they are battling a cached redirect. Clearing browser caches, purging CDN edges, and using validators that bypass local caching are mandatory steps when debugging complex chains.

Industry Standards and Benchmarks

The digital infrastructure industry has established strict, quantifiable benchmarks regarding how redirects should be handled to maintain optimal performance and search visibility. The most critical benchmark comes directly from Google's official Webmaster Guidelines: The Five-Hop Limit. Googlebot is explicitly programmed to follow a maximum of five consecutive redirect hops per crawl attempt. If a URL requires a sixth hop, the bot abandons the chain entirely, flags the URL with a redirect error in Google Search Console, and refuses to index the final destination. While five is the absolute mechanical limit, the widely accepted SEO industry standard is to never exceed one single redirect hop. Any chain of two or more hops is considered a technical defect requiring immediate remediation.

From a performance perspective, redirects are judged against the standards of Google's Core Web Vitals, specifically the Largest Contentful Paint (LCP) metric. LCP measures how long it takes for the largest image or text block to render on the screen, and the industry standard for a "Good" user experience dictates that LCP must occur within 2.5 seconds of the initial click. Because a single unoptimized redirect hop can easily add 300 to 500 milliseconds of latency on a mobile 3G/4G connection, a multi-hop chain can consume up to 40% of the entire 2.5-second budget before a single byte of HTML is even processed. Therefore, web performance benchmarks dictate that server-side redirect latency should never exceed 100 milliseconds total.

Regarding status codes, the industry standard for permanent URL migrations is the exclusive use of the 301 Moved Permanently or 308 Permanent Redirect codes. The use of 302 or 307 codes for permanent changes is flagged as a critical error by every major enterprise SEO auditing platform. Furthermore, industry standards established by the World Wide Web Consortium (W3C) mandate that all redirects must be accompanied by a valid absolute URL in the Location header (e.g., https://example.com/page), rather than a relative URL (e.g., /page), to prevent parsing errors across different types of legacy browser software.

Comparisons with Alternatives

While dedicated redirect chain validators are the most precise tools for analyzing specific URL pathways, they are not the only method available for diagnosing redirection issues. Understanding how a live validator compares to alternative diagnostic approaches allows webmasters to choose the right tool for the specific context of their problem.

The primary alternative to a live validator is Log File Analysis. Every time a server processes a request, it writes a line of text into an access log file, recording the timestamp, the requested URL, the User-Agent, and the HTTP status code returned. Log file analysis involves downloading millions of these lines and using specialized software to aggregate the data. The massive advantage of log analysis is that it shows exactly how search engine bots are actually experiencing your site in the real world, rather than running a simulated test. It can uncover hidden redirect chains that a webmaster didn't even know existed. However, log analysis is incredibly complex, requires server access, and is retrospective—it only shows you the chains that have already been crawled. A live validator, by contrast, is instant, requires no server access, and allows you to test fixes in real-time before bots ever see them.

Another common alternative is the use of Desktop Crawling Software (such as Screaming Frog SEO Spider). A crawler is essentially an automated bot that starts at a website's homepage and follows every single internal link it can find, mapping the entire site architecture. Crawlers are unparalleled for finding massive, site-wide redirect issues, such as thousands of internal links pointing to old HTTP URLs. However, running a full site crawl on an enterprise domain with millions of pages can take days and requires significant computing power. A dedicated redirect validator is designed for surgical precision. When a developer needs to instantly verify the specific forwarding path of a single marketing campaign URL, waiting hours for a site-wide crawl is highly inefficient.

Finally, developers frequently rely on Manual Browser Network Tabs. By opening Google Chrome's Developer Tools, navigating to the Network tab, and checking the "Preserve log" option, a developer can manually click a link and watch the HTTP status codes populate in real-time. This method is free, built into every browser, and excellent for quick, one-off checks. However, the browser network tab is heavily influenced by local browser caching, extensions, and the user's specific geographic location. It also cannot easily simulate different User-Agents or export clean, shareable reports of the chain. A dedicated validator strips away these local variables, providing a clean, objective, server-to-server analysis of the exact HTTP headers being transmitted.

Frequently Asked Questions

What exactly is the difference between a 301 and a 302 redirect? A 301 redirect indicates that a resource has been moved permanently to a new location, instructing search engines to transfer all historical ranking signals, link equity, and authority to the new URL. A 302 redirect indicates a temporary move, explicitly telling search engines to keep the original URL in their index because the change will eventually be reverted. Using a 302 when you mean to use a 301 is a critical SEO error, as the new destination page will struggle to rank while the search engine waits for the temporary redirect to end.

Why does my browser say "ERR_TOO_MANY_REDIRECTS"? This error message is the browser's defense mechanism against an infinite redirect loop. It occurs when server rules are configured such that URL A redirects to URL B, but URL B is configured to redirect back to URL A. The browser gets caught bouncing back and forth between the two locations. To prevent the browser from crashing and consuming infinite network resources, modern browsers are hard-coded to stop following redirects after a specific threshold (typically 20 hops) and display this error to the user.

Do redirect chains permanently damage my website's SEO? Redirect chains do not cause permanent, irreversible damage, but they actively suppress your website's search engine performance for as long as they exist. By forcing search engine crawlers to waste their designated crawl budget on multiple intermediate hops, you prevent them from discovering and indexing your actual content. Once you use a validator to identify the chain and update your server to point the original URL directly to the final destination in a single hop, search engines will eventually recrawl the path, recognize the fix, and restore the proper flow of link equity.

Can I use JavaScript to redirect users instead of server rules? While you technically can use JavaScript (e.g., window.location.href) to redirect users, it is highly discouraged for both performance and SEO reasons. Server-side redirects (like a 301 via .htaccess) occur instantaneously at the network level before any data is downloaded. A JavaScript redirect requires the user's browser to download the HTML document, download the JavaScript file, parse the code, and execute it before the redirect even begins, adding massive latency. Furthermore, many search engine crawlers do not execute JavaScript efficiently, meaning they may completely fail to see the redirect and index the wrong page.

How many redirect hops are considered acceptable? The strict industry standard and best practice is a maximum of one single hop. Any URL should redirect directly to its final, 200 OK destination. While Google's automated crawlers will technically follow up to five consecutive hops before abandoning the request, relying on this limit is a poor strategy. Every single hop adds hundreds of milliseconds of network latency, degrading the user experience, increasing bounce rates, and negatively impacting Core Web Vitals metrics like Largest Contentful Paint.

How do I fix a redirect chain once I have identified it? Fixing a redirect chain requires updating the configuration rules on your web server or within your Content Management System (CMS). If you identify that URL A redirects to URL B, and URL B redirects to URL C, you do not delete the rule for URL A. Instead, you modify the rule for URL A so that it points directly to URL C. By ensuring that all legacy URLs point directly to the absolute newest version of the page, you collapse the chain into a single, efficient hop, eliminating unnecessary server requests and preserving SEO authority.
