So you want to implement JavaScript redirects but aren’t sure how they work?
Yes, they are more difficult to implement than standard redirects.
Ideally, you should use 301, 302, or 307-based redirects for implementation. This is standard best practice.
But… what if you don’t have that level of access? What if you have a problem creating default redirects in a way that benefits the site as a whole?
This is where using JavaScript redirects comes into play.
However, they are not a best practice that you should use exclusively.
But there are situations where you just can’t avoid using a JavaScript redirect.
The following is a basic introduction to JavaScript redirects, when to use them, how to use them, and best practices to use when using these types of redirects for SEO.
What Are JavaScript Redirects?
JavaScript redirects are essentially one of several methods to notify users and web crawlers that a page is available elsewhere.
They’re often used to notify users of changes in the URL structure, but they can be used for almost anything.
Most modern websites use these types of redirects to redirect to HTTPS versions of webpages.
Then, when someone visits the original URL, the browser loads the JavaScript file and executes the code it contains. If the script contains instructions to open a different URL, this is done automatically.
Performing redirects in this way is useful in a number of ways.
For example, you can switch URLs without manually updating every single URL on your site. In addition, JavaScript redirects can make it easier for search engines to find your own content.
A Quick Overview Of Redirect Types
There are several basic types of redirects, all of which are beneficial depending on your situation.
Server-side Redirects
Ideally, most redirects are server-side redirects.
These types of redirects come from the server and here the server decides where to redirect the user or search engine when a page loads. And the server does this by returning a 3xx HTTP status code.
For SEO reasons, you will probably use server-side redirects most of the time. Client-side redirects have some drawbacks and are usually appropriate for more specific situations.
Client-side Redirects
Client-side redirects are those where the browser decides where to redirect the user to. You shouldn’t need to use these unless you’re in a situation where you have no other option.
Meta Refresh Redirects
Meta refresh redirect has a bad rap and reputation in the SEO community.
And with good reason: they are not supported by all browsers and can be confusing for the user. Instead, Google recommends using a server-side 301 redirect instead of meta-refresh redirects.
JavaScript Redirects
However, JavaScript redirects use the JavaScript language to send instructions to the browser to redirect users to a different URL. There is a prevailing opinion that JavaScript redirects cause problems for SEO.
Although Google has good JavaScript rendering capabilities these days, JavaScript can still cause problems. This also applies to other types of platforms like Spotify and other ecommerce platforms.
However, if you are in a situation where you can only use a JavaScript redirect as your only choice, then you can use JavaScript only.
Google’s Gary Illyes also stated as recently as 2020 that JavaScript redirects are “probably not a good idea”.

Best Practices For SEO-Friendly JavaScript Redirects
Whether you’re using traditional redirects or JavaScript redirects, there are some best practices you need to follow to avoid messing things up for SEO.
These best practices include avoiding redirection chains and redirection loops.
Avoid Redirect Chains
A redirect chain is a long chain of redirect hops, referring to any situation where you have more than 1 redirect in a chain.
detour 1 > detour 2 > detour 3 > detour 4 > redirect 5
Why are these bad? Google can only handle up to three redirects, although they have been known to handle more.
Google’s John Mueller recommends fewer than 5 hops per redirect.
“It does not matter. The only thing I would look for is that you have less than 5 hops for URLs that are crawled frequently. With multiple hops, the main effect is that it’s a bit slower for users. Search engines simply follow the redirection chain (for Google: up to 5 hops in the chain per crawl attempt).”
Ideally, webmasters should aim for no more than one hop.
What happens if you add another hop? It slows down user experience. And more than five leads to significant confusion as to whether Googlebot can even understand your site.
Fixing redirect chains can take a lot of work depending on the complexity and setup.
But the main principle of repairing redirect chains is: just make sure you follow two steps.
First remove the extra hops in the forwarder so that it is less than five hops.
Second, implement a redirect that redirects the previous URLs
Avoid Redirect Loops
Redirect loops, by comparison, are essentially an endless loop of redirects. These loops occur when you redirect a URL to itself. Or you accidentally redirect a URL within a redirection chain to a URL earlier in the chain.
Example of a detour loop: detour 1 > detour 2 > detour 3 > redirect 2
This is why monitoring website redirects and URLs is so important: you don’t want a situation where you implement a redirect only to find out 3 months later that the redirect you created months ago was the cause of problems because it caused a redirection loop.
There are several reasons why these loops are disastrous:
Regarding users, redirect loops remove all access to a specific resource located on a URL and cause the browser to show the error “This page has too many redirects”.
For search engines, redirect loops can be a significant waste of your crawl budget. They also create confusion for bots.
This creates what is known as a crawler trap, and the crawler cannot easily get out of the trap unless manually directed elsewhere.
Fixing redirect loops is pretty easy: all you have to do is remove the redirect that is causing the chain to loop and replace it with a 200 OK working URL.
Want To Use JavaScript Redirects For SEO? Not So Fast…
Be careful when creating JavaScript redirects as they may not be the best redirect solution depending on what you have access to.
They should not be your first choice if you have access to other redirects as these other types of redirects are preferred.
But if they’re the only option, maybe don’t shoot yourself in the foot.
