Reroutes for SEO ought to be utilized properly due to the fact that they affect how sites are crawled and indexed by Google.
While most people think of redirects as a web detour indication, much more is taking place, and it’s surprisingly enjoyable to discover.
Keep checking out for a thorough introduction of redirects and the correct application for technical SEO.
What Is A Redirect?
Site redirects tell browsers and online search engine information about a URL and where to discover the web page.
A URL redirect involves code executed to a specific URL, or a group of URLs so that the user (or search engine) is sent to a various page to the real URL that was input or clicked.
A redirect can be set as a:
- Short-term redirect: 302, 303, 307, 308.
- Irreversible redirect: 301.
When To Utilize Redirects
The primary factors to use redirects are:
- A private page or whole domain has been moved (URL altered).
- To permit the use of URL shorteners or ‘pretty URLs.’
- Site migration (e.g., HTTP to HTTPS).
For SEO purposes, URL redirects are necessary due to the fact that they:
- Forward authority of any links indicating a page that has actually moved or been erased.
- Avoid 404 page not found mistakes (although in some cases it is better to leave a 404).
Redirects can be carried out on a group or domain-wide basis but typically need to be set on a private basis to prevent concerns.
When utilizing RegEX for group redirects, it can have unexpected results if your reasoning isn’t flawless!
Types Of Redirects
There are three main kinds of redirects:
- Meta Refresh redirects are set at the page level however are usually not suggested for SEO purposes. There are 2 kinds of meta redirect: delayed which is seen as a short-lived redirect, and instant, which is seen as a long-term redirect.
- HTTP redirects are set server-side and the best technique for SEO functions– we covered extensive below.
What Is A HTTP Response Status Code?
Browsers and online search engine crawlers like GoogleBot are called user representatives.
When a user representative tries to access a web page, what occurs is that the user representative makes a request, and the site server problems a reaction.
The reaction is called an HTTP reaction status code. It offers a status for the request for a URL.
In the circumstance where a user agent like GoogleBot requests a URL, the server provides an action.
For instance, if the request for a URL achieves success, the server will provide a response code of 200, which means the request for a URL was successful.
So, when you think of a GoogleBot reaching a site and attempting to crawl it, what’s taking place is a series of demands and actions.
An HTTP redirect is a server response to request a URL.
If the URL exists at a various URL (due to the fact that it was moved), the server informs the user representative that the URL request is being rerouted to a various URL.
The action code for an altered URL is normally in the type of a 301 or 302 response status code.
The whole 3xx series of response codes communicate much details that can optionally be acted on by the user representative.
An example of an action that the user representative can take is to save a cache of the new URL so that the next time the old URL is requested, it will request for the brand-new URL rather.
So, a 301 and a 302 redirect is more than an internet roadway sign that states, “Go here, not there.”
3XX Series Of Status Codes
Redirects are more than simply the 2 status codes everybody recognizes with, the 301 and 302 reaction codes.
There are a total of 7 main 3xx reaction status codes.
These are the various sort of redirects readily available for usage:
- 300 Multiple Choices.
- 301 Moved Permanently.
- 302 Found.
- 303 See Other.
- 304 Not Customized.
- 305 Usage Proxy.
- 306 (Unused).
- 307 Temporary Redirect.
- 308 Irreversible Redirect.
Some of the above status codes have not been around as long and may not be used. So, prior to using any redirect code aside from 301 or 302, be sure that the designated user representative can interpret it.
Since GoogleBot uses the latest version of Chrome (called a headless web browser), it’s simple to examine if a status code works by inspecting if Chrome recognizes the status code with a browser compatibility list.
For SEO, one ought to stick to using the 301 and 302 reaction codes unless there is a particular reason to use one of the other codes.
301: Moved Completely
The 301 status code is consistently referenced as the 301 redirects. However the main name is 301 Moved Permanently.
The 301 redirect indicates to a user agent that the URL (in some cases described as a target resource or merely resource) was altered to another area and that it ought to use the brand-new URL for future requests.
As discussed previously, there is more details as well.
The 301 status code likewise suggests to the user agent:
- Future ask for the URL need to be made with the new URL.
- Whoever is making the request ought to update their links to the brand-new URL.
- Subsequent demands can be altered from GET to POST.
That last point is a technical problem. According to the main requirements for the 301 status code:
“Keep in mind: For historic factors, a user representative MAY alter the request approach from POST to GET for the subsequent demand. If this behavior is undesired, the 308 (Irreversible Redirect) status code can be utilized rather.”
For SEO, when online search engine see a 301 redirect, they pass the old page’s ranking to the new one.
Before making a modification, you must be careful when utilizing a 301 redirect. The 301 redirects must just be used when the modification to a new URL is permanent.
The 301 status code need to not be used when the modification is temporary.
Additionally, if you change your mind later on and return to the old URL, the old URL might not rank anymore and may take time to gain back the rankings.
So, the main thing to remember is that a 301 status code will be used when the change is irreversible.
The main point to understand about the 302 status code is that it works for situations where a URL is temporarily changed.
The significance of this action code is that the URL is temporarily at a various URL, and it is recommended to utilize the old URL for future requests.
The 302 redirect status code likewise features a technical caution related to GET and Post:
“Keep in mind: For historical factors, a user agent MAY change the request approach from POST to GET for the subsequent demand. If this habits is undesired, the 307 (Short-term Redirect) status code can be used instead.”
The reference to “historical factors” may refer to old or buggy user agents that might alter the request approach.
307: Temporary Redirect
A 307 redirect implies the requested URL is momentarily moved, and the user agent ought to utilize the original URL for future requests.
The only difference in between a 302 and a 307 status code is that a user representative should ask for the new URL with the same HTTP demand utilized to request the initial URL.
That implies if the user agent requests the page with a GET request, then the user representative need to use a GET request for the new temporary URL and can not use the POST request.
The Mozilla documentation of the 307 status code describes it more plainly than the official paperwork.
“The server sends this action to direct the client to get the requested resource at another URI with same method that was used in the prior demand.
This has the same semantics as the 302 Found HTTP response code, with the exception that the user representative need to not change the HTTP method used: if a POST was utilized in the first demand, a POST must be utilized in the second request.”
Aside from the 307 status code requiring subsequent requests to be of the exact same kind (POST or GET) which the 302 can go in either case, everything else is the very same between the 302 and the 307 status codes.
302 Vs. 307
You may handle a redirect via server config files.htaccess on Apache, example.conf file on Nginx or via plugins if you are using WordPress.
In all instances, they have the same syntax for composing redirect rules. They vary only with commands utilized in configuration files. For instance, a redirect on Apache will look like this:
Options +FollowSymlinks RewriteEngine on RedirectMatch 301 ^/ oldfolder// newfolder/
(You can read about symlinks here.)
On Nginx servers, it will look like this:
reword ^/ oldfolder// newfolder/ long-term;
The commands utilized to tell the server’s status code of redirect and the action command differ.
- Servers status code of redirect: “301 ″ vs. “irreversible.”
- Action command: “RedirectMatch” vs. “reword.”
However the redirect syntax (^/ oldfolder// newfolder/) is the exact same for both.
On Apache, ensure that mod_rewrite and mod_alias modules (responsible for dealing with redirects) are enabled on your server.
Since the most commonly spread out server type is Apache, here are examples for.htaccess apache files.
Make certain that the.htaccess file has these 2 lines above the redirect rules and put the rules below them:
Alternatives +FollowSymlinks RewriteEngine on
Read the official documents to find out more about the RewriteEngine.
To comprehend the examples listed below, you might refer to the table listed below on RegExp essentials.
|*||zero or more times|
|+||One or more times|
|.||any single character|
|?||Absolutely no or one time|
|^||Start of the string|
|$||End of the string|
|| b||OR operadn” |” a or b|
|(z)||remembers the match to be utilized when calling $1|
How To Develop Redirects
How To Create A Redirect For A Single URL
The most common and commonly utilized kind of redirect is when deleting pages or changing URLs.
For instance, state you altered the URL from/ old-page/ to/ new-page/. The redirect guideline would be:
RewriteRule ^ old-page(/? |/. *)$/ new-page/ [R=301, L] Or RedirectMatch 301 ^/ old-page(/? |/. *)$/ new-page/
The only difference in between the two methods is that the very first utilizes the Apache mod_rewrite module, and the second uses mod_alias. It can be done utilizing both techniques.
The regular expression “^” suggests the URL must begin with “/ old-page” while (/? |/. *)$ indicates that anything that follows “/ old-page/” with a slash “/” or without a specific match must be redirected to/ new-page/.
We might likewise use (. *), i.e., ^/ old-page(. *), but the problem is, if you have another page with a comparable URL like/ old-page-other/, it will also be redirected when we just want to reroute/ old-page/.
The following URLs will match and be directed to a new page:
|/ old-page/||/ new-page/|
|/ old-page||/ new-page/|
|/ old-page/? utm_source=facebook.com||/ new-page/? utm_source=facebook.com|
|/ old-page/child-page/||/ new-page/|
It will redirect any variation of the page URL to a new one. If we utilize redirect in the list below kind:
Reroute 301/ old-page// new-page/
Without routine expressions, all URLs with UTM query string, e.g.,/ old-page? utm_source=facebook.com (which is common because URLs are used to be shared over a social network), would wind up as 404s.
Even/ old-page without a tracking slash “/” would wind up as a 404.
Redirect All Other than
Let’s say we have a bunch of URLs like/ category/old-subcategory -1/,/ category/old-subcategory -2/,/ category/final-subcategory/ and wish to merge all subcategories into/ category/final-subcategory/. We need the “all except” guideline here.
Otherwise, if we have some properties like “/ category/image. jpg,” it will also be rerouted to “/ final-subcategory/” and cause an image break.
You can utilize the guideline below if you did a classification restructuring and wish to move everything from the old directory to the new one.
RewriteRule ^ old-directory$/ new-directory/ [R=301, NC, L] RewriteRule ^ old-directory/(. *)$/ new-directory/$1 [R=301, NC, L] I utilized $1 in the target to inform the server that it must remember whatever in the URL that follows/ old-directory/ (i.e.,/ old-directory/subdirectory/) and pass it (i.e., “/ subdirectory/”) onto the location. As a result, it will be rerouted to/ new-directory/subdirectory/.
I utilized two guidelines: one case without any tracking slash at the end and the other one with a trailing slash.
I could combine them into one rule using (/? |. *)$ RegExp at the end, but it would trigger problems and include a “//” slash to the end of the URL when the asked for URL with no routing slash has a question string (i.e., “/ old-directory? utm_source=facebook” would be redirected to “/ new-directory//? utm_source=facebook”).
Eliminate A Word From URL
Let’s state you have 100 URLs on your website with the city name “Chicago” and want to remove them.
For the URL http://yourwebiste.com/example-chicago-event/, the redirect rule would be:
RewriteRule ^(. *)-chicago-(. *) http://% /$1-$2 [NC, R=301, L] If the example URL is in the form http://yourwebiste.com/example/chicago/event/, then the redirect would be: RewriteRule ^(. *)/ chicago/(. *) http://% /$1/$2 [NC, R=301, L] Set A Canonical URL
Having canonical URLs is the most fundamental part of SEO.
If missing, you may threaten your site with duplicate content issues due to the fact that search engines treat URLs with “www” and “non-www” variations as various pages with the same material.
For that reason, you need to ensure you run the site just with one version you choose.
If you wish to run your website with the “www” version, utilize this guideline:
RewriteCond % HTTP_HOST ^ yourwebsite.com [NC] RewriteRule ^(. *)$ http://www.yourwebsite.com/$1 [L, R=301] For a “non-www” version: RewriteCond % ^ www.yourwebsite.com [NC] RewriteRule ^(. *)$ http://yourwebsite.com/$1 [L, R=301] Routing slash is likewise part of canonicalization because URLs with a slash at the end or without are likewise treated in a different way. RewriteCond % !-f RewriteRule ^(. * [^/]$/$1/ [L, R=301] This will make certain the/ example-page is rerouted to/ example-page/. You might choose to remove the slash rather of including then you will need the other guideline below: RewriteCond % !-d RewriteRule ^(. *)/$/$1 [L, R=301]HTTP To HTTPS Redirect
After Google’s initiative to motivate site owners to use SSL, moving to HTTPS is one of the typically used redirects that nearly every site has.
The reword guideline below can be utilized to force HTTPS on every website.
RewriteCond % ^ yourwebsite.com [NC, OR] RewriteCond % ^ www.yourwebsite.com [NC] RewriteRule ^(. *)$ https://www.yourwebsite.com/$1 [L, R=301, NC] Using this, you can integrate a www or non-www version reroute into one HTTPS redirect guideline.
Redirect From Old Domain To New
This is likewise one of the most used redirects when you choose to rebrand and require to change your domain. The rule below redirects old-domain. com to new-domain. com.
RewriteCond % ^ old-domain. com$ [OR] RewriteCond % ^ www.old-domain.com$ RewriteRule (. *)$ http://www.new-domain.com/$1 [R=301, L] It uses two cases: one with the “www” version of URLs and another “non-www” due to the fact that any page for historic factors may have incoming links to both variations.
A lot of site owners use WordPress and might not require a.htaccess file for redirects but use a plugin instead.
Dealing with redirects using plugins might be slightly different from what we went over above. You might need to read their documentation to handle RegExp properly for the particular plugin.
From the existing ones, I would advise a complimentary plugin called Redirection, which has numerous criteria to manage redirect guidelines and numerous helpful docs.
Reroute Finest Practices
1. Do not Reroute All 404 Broken URLs To The Homepage
This case frequently takes place when you are too lazy to investigate your 404 URLs and map them to the appropriate landing page.
According to Google, they are still all dealt with as 404s.
Yeah, it’s not a terrific practice (confuses users), and we primarily treat them as 404s anyway (they’re soft-404s), so there’s no benefit. It’s not seriously broken/bad, but additional complexity for no good factor– make a much better 404 page rather.
— John (@JohnMu) January 8, 2019
If you have too many pages like this, you ought to think about creating lovely 404 pages and engaging users to search further or find something besides what they were trying to find by showing a search option.
It is strongly suggested by Google that redirected page material should be comparable to the old page. Otherwise, such a redirect might be thought about a soft 404, and you will lose the rank of that page.
2. Get Mobile Page-Specific Redirects Right
If you have various URLs for desktop and mobile sites (i.e., “example.com” for desktop and “m.example.com” for mobile), you need to make certain to redirect users to the appropriate page of the mobile version.
Correct: “example.com/sport/” to “m.example.com/sport/”
Wrong: “example.com/sport/” to “m.example.com”
Also, you need to guarantee that if one page is 404 on the desktop, it must also be 404 on mobile.
If you have no mobile version for a page, you can avoid rerouting to the mobile version and keep them on the desktop page.
3. How To Utilize Meta Refresh
It is possible to do a redirect utilizing a meta revitalize tag like the example below:
If you place this tag in/ old-page/, it will redirect the user immediately to/ new-page/.
Google does not restrict this redirect, however it doesn’t suggest utilizing it.
A meta refresh type redirect ought to simply work. We do not recommend it for 2 reasons: UX (it keeps the page in browser history, afaik) & processing time (we need to parse the page to see it). As soon as processed, it’s similar to a redirect.

4. Avoid Redirect Chains
This message shows when you have a wrong routine expression setup and winds up in an infinite loop.
Screenshot by author, December 2022 Usually, this occurs when you have a redirect chain. Let’s state you rerouted page 1 to page 2 a long period of time back. You might have forgotten that
page 1 is redirected and chosen to redirect page 2 to page 1 once again. As a result, you will wind up with a guideline like this: RewriteRule ^ page1/ page2 [R
=301, NC, L] RewriteRule ^ page2/ page1 [R=301, NC, L] This will develop an unlimited loop and produce the error shown above. Conclusion Understanding what
redirects are and which circumstance needs a specific status code is basic to
websites effectively. It’s a core part of understanding SEO. Numerous scenarios need accurate knowledge of redirects, such as migrating a website to a new domain or producing a momentary holding page URL for a web page that will return under its typical URL. While a lot is possible with a plugin, plugins can be misused without correctly understanding when and why to utilize a particular
sort of redirect. More Resources: Included Image:
