Redirects are a crucial important of website management, ensuring users and search engines can find content even when URLs change. At i-engage, we understand the importance of implementing redirects correctly to maintain seamless navigation and strong SEO performance.
Here’s a detailed guide on everything you need to know about redirects: what they are, when to use them, how to implement them, and common issues to avoid.
What Are Redirects?
Redirects automatically send a webpage visitor from an old URL to a new one without requiring any action from the user. Every webpage has a unique URL (Uniform Resource Locator), allowing browsers to request the correct information. When a browser requests a page with a redirect, it is instructed to go to a different address, meaning the content of the original page is no longer available at the old URL.
Types of Redirects
There are several types of redirects, each with different purposes and methods of implementation:
Permanent and Temporary Redirects
When a redirect is placed on a URL, search engines must determine if it’s a permanent or temporary change.
Permanent Redirects (301 and 308):
– 301 (Moved Permanently): Indicates that the resource at the original URL has permanently moved to a new location. It allows the request method to change from POST to GET. This means that any data sent in the original request may be altered, which can be significant if you’re dealing with forms or other data submissions.
– 308 (Permanent Redirect): Similar to 301, but maintains the original request method. This is important for preserving the exact data and method used in the initial request, which can be crucial for applications relying on consistent POST data.
Temporary Redirects (302 and 307):
– 302 (Found): Indicates that the move is temporary and the original URL might be used again in the future. It allows the request method to change, providing flexibility but potentially altering the way data is handled in the process.
– 307 (Temporary Redirect): Similar to 302, but recommends retaining the original request method. This helps ensure that any data sent in a POST request remains intact, maintaining the consistency of user interactions.
Meta Refresh
A meta refresh is a client-side redirect where the browser identifies the need to go to a different page. Meta refreshes can happen instantly or after a delay (e.g., “You will be redirected in 5 seconds”). Google treats instant meta refreshes as permanent and delayed meta refreshes as temporary. This type of redirect can be useful for simple redirections but may not be as reliable or SEO-friendly as server-side redirects.
JavaScript Redirect
JavaScript redirects are also client-side redirects, using JavaScript to navigate users from one page to another. Google advises using JavaScript redirects only if server-side or meta refresh redirects aren’t feasible, as search engines may miss these redirects if they don’t render the page. This makes JavaScript redirects less reliable for ensuring all users and bots reach the intended destination.
Server-Side Redirects
Server-side redirects are the safest method for redirecting URLs. These require access to the server’s configuration files and include several options, each suitable for different scenarios. Server-side redirects are generally preferred because they are handled by the server before the page loads, making them faster and more reliable.
Why Use Redirects?
Redirects serve multiple purposes, benefiting both human visitors and search engines:
Human Visitors
Redirects ensure that users can access the correct content even if they use outdated URLs. For instance, a bookmarked URL can still lead to the desired content without resulting in a 404 error, enhancing user experience. This is crucial for maintaining a seamless user experience, as visitors are automatically guided to the correct page without needing to navigate the site manually.
Search Engines
Search engines use redirects to find and index the correct content. Without redirects, old URLs may lead to 404 errors, causing search engines to de-index those pages. Proper redirects ensure search engines understand the new location of the content and can pass ranking signals from the old URL to the new one. This helps maintain the SEO value of your site and ensures that search engines can efficiently index and rank your content.
Common SEO Use Cases for Redirects
Vanity URLs
Vanity URLs are short, memorable URLs that redirect to longer, more complex URLs. They are often used in marketing to make URLs easy to remember and type. For example, a TV advert might tell viewers to visit www.example-competition.com to enter their competition. This URL might redirect to www.example.com/competitions/tv-ad-2024, which is far harder for viewers to remember and enter correctly. Using a vanity URL like this means website owners can use short URLs that are easy to remember and spell without having to set up the content outside of their current website structure.
URL Rewrites
When a URL needs to be edited (e.g., due to a name change or a correction), a redirect from the old URL to the new one ensures users and search engines can find the updated content. This is particularly important for maintaining the accuracy and relevance of your site’s URLs, especially when product names change, spelling mistakes are corrected, or dates need to be updated.
Moving Content
Website restructuring often necessitates redirects to ensure that moved content remains accessible. This is crucial when merging subfolders or moving content between subdomains. For example, you may be consolidating content from multiple subfolders into a single, more organized structure. Implementing redirects ensures that users and search engines can still find the content even after it has been moved.
Moving Domains
Domain migrations, such as changing from a .co.uk to a .com address or rebranding, require redirects to ensure all URLs on the old domain point to their counterparts on the new domain. This helps preserve the SEO value of the old URLs and ensures that users can still find the content they are looking for, even after the domain change.
HTTP to HTTPS
Migrating from an insecure (HTTP) to a secure (HTTPS) protocol involves implementing redirects across the entire site to maintain security and SEO integrity. This is crucial for ensuring that all traffic is directed to the secure version of your site, protecting user data and enhancing the credibility of your website.
Redirect Problems to Avoid
Loops
Redirect loops occur when two URLs redirect to each other, creating an endless loop. This confuses search engines and prevents users from accessing the content. For example, URL A redirects to URL B, and URL B redirects back to URL A. This makes it unclear which page is supposed to be visited and can result in users and search engines being stuck in a loop.
Chains
A redirect chain involves multiple redirects from one URL to another, which can slow down page load times and hinder search engine crawling. For example, URL A redirects to URL B, which redirects to URL C, which redirects to URL D. This isn’t too much of an issue unless the chain gets too big. URL chains can start to affect load speed. John Mueller, Search Advocate at Google, has also stated in the past that “The only thing I’d watch out for is that you have less than 5 hops for URLs that are frequently crawled. With multiple hops, the main effect is that it’s a bit slower for users. Search engines just follow the redirect chain (for Google: up to 5 hops in the chain per crawl attempt).”
Soft 404s
Soft 404s happen when a redirect leads to a page that doesn’t match the original content. For example, if Page A redirects to Page B but the two are not similar in content, the search engines may not pass any of the value of Page A to Page B. This can be reported as a “soft 404” in Google Search Console. This typically happens when a webpage (e.g., a product page) is deleted and the URL is redirected to the homepage. Anyone clicking on the product page from search results wouldn’t find the product information they were expecting if they landed on the homepage. The signals and value of the original page won’t necessarily be passed to the homepage if it doesn’t match the user intent of searchers.
Ignoring Previous Redirects
Failing to consider existing redirects can create loops or chains. It’s essential to review previous redirects before implementing new ones to avoid conflicts. Without checking to see what redirects are already active on the site, you may run the risk of creating loops or chains.
Frequent Changes
Another reason for planning redirects in advance is to limit the need to frequently change them. It is important from an internal productivity perspective, especially if you involve other teams in their implementation. Most crucially, though, is that you may find the search engines struggle to keep up with frequent changes, especially if you incorrectly suggest the redirect is permanent by using a 301 or 308 status code.
Good Practices for Implementing Redirects
Create a Redirect Map
A redirect map is a plan that outlines which URLs should redirect to which destinations. This helps visualize the redirects and identify potential issues before implementation. It can be as simple as a spreadsheet with a column of “from” URLs and “to” URLs. This way, you have a clear visual of what redirects will be implemented and you can identify any issues or conflicts beforehand.
Assess Existing Redirects
Review existing redirects to avoid creating loops or chains. Tools like crawling software or browser plugins can help identify current redirects. If you keep a running redirect map, look back at previous redirects to see if your new ones will impact them at all. For example, would you create a redirect chain or loop by adding new redirects to a page that already is redirected from another? This will also help you see if you have moved a page to a new URL several times over a short period of time. If you do not have a map of previous redirects, you may be able to pull redirects from your server configuration files (or at least ask your hosting provider to do this). The format of these files will vary depending on the type of server your website uses, so you may need the help of a developer to understand them.
Plan Ahead
Frequent changes to redirects can confuse search engines. Plan redirects carefully to minimize the need for frequent updates. For instance, instead of setting up temporary redirects and then updating them to permanent ones, decide upfront whether the redirect needs to be temporary or permanent.
Alternatives to Redirects
In cases where redirects are not possible, consider these alternatives:
Canonical Tags
Canonical tags indicate to search engines which version of a page should be considered the primary one. This is useful when you cannot implement a redirect but need to guide search engines to the correct page. This helps consolidate duplicate content under a single URL, ensuring search engines know which page to prioritize.
Crypto Redirects
A crypto redirect is a link on the page indicating the new location of the content. It requires user action and does not work as a redirect for search engines, but it can serve as a temporary solution. For example, adding a message at the top of a webpage saying “We’ve moved! Click here to visit our new page.” This isn’t ideal for SEO but can be a temporary measure if other options aren’t available.
The Role of Redirects in SEO
Redirects are essential tools for maintaining website usability and SEO performance. Properly implemented, they guide users and search engines to the correct content, preserving the value and relevance of your site. However, incorrect implementation can lead to issues such as redirect loops, chains, and soft 404s. By following best practices and planning redirects carefully, you can ensure a smooth and efficient experience for both users and search engines.
