But there are some situations where you simply can not prevent utilizing a JavaScript redirect.

The following is a basic primer on JavaScript reroutes, when to use them, how to utilize them, and best practices you should use when utilizing these types of redirects for SEO.

What Are JavaScript Redirects?

JavaScript redirects, essentially, are one of several approaches of notifying users and web spiders that a page is offered in another place.

They are often utilized to inform users about changes in the URL structure, but they can be used for practically anything.

A lot of contemporary sites use these types of redirects to reroute to HTTPS variations of web pages.

Then, whenever somebody visits the initial URL, the browser loads the JavaScript file and performs whatever code is inside of it. If the script consists of instructions to open a different URL, it does this instantly.

Doing redirects in this manner is useful in numerous methods.

For example, you can change URLs without by hand updating every single URL on your website. In addition, JavaScript reroutes can make it easier for online search engine to find your own content.

A Quick Introduction Of Redirect Types

There are a number of standard redirect types, all of which are useful depending on your situation.

Server-side Reroutes

Ideally, the majority of redirects will be server-side redirects.

These types of redirects come from on the server, and this is where the server decides which area to redirect the user or search engine to when a page loads. And the server does this by returning a 3xx HTTP status code.

For SEO reasons, you will likely utilize server-side reroutes the majority of the time. Client-side redirects have some downsides, and they are generally ideal for more specific circumstances.

Client-side Redirects

Client-side redirects are those where the web browser is what chooses the area of where to send out the user to. You must not need to use these unless you remain in a situation where you do not have any other option to do so.

Meta Refresh Redirects

The meta refresh reroute gets a bum rap and has a terrible credibility within the SEO community.

And for good reason: they are not supported by all browsers, and they can be puzzling for the user. Instead, Google recommends using a server-side 301 redirect rather of any meta refresh redirects.

JavaScript Redirects

JavaScript redirects, however, utilize the JavaScript language to send out guidelines to the web browser to redirect users to another URL. There is a dominating belief that JavaScript redirects cause problems for SEO.

Although Google does have great JavaScript rendering abilities nowadays, JavaScript can still provide concerns. This holds true for other kinds of platforms likewise, such as Spotify and other ecommerce platforms.

If, however, you’re in a situation where you can only use a JavaScript reroute as your only option, then you can only utilize JavaScript.

Also, Google’s Gary Illyes has actually specified as recently as 2020 that JavaScript Redirects “are probably not an excellent concept.”

Js redirects are probably not an excellent concept though.

Finest Practices For SEO-Friendly JavaScript Redirects

Regardless of whether you are using standard redirects or JavaScript reroutes, there are a number of finest practices you need to follow in order to not mess things up for SEO.

These best practices include preventing redirect chains and redirect loops.

What’s the difference?

Prevent Redirect Chains

A redirect chain is a long chain of redirect hops, referring to any circumstance where you have more than 1 redirect in a chain.

Example of a redirect chain:

Redirect 1 > redirect 2 > redirect 3 > redirect 4 > redirect 5

Why are these bad? Google can just process as much as 3 redirects, although they have actually been understood to process more.

Google’s John Mueller advises less than 5 hops per redirect.

“It does not matter. The only thing I ‘d keep an eye out for is that you have less than 5 hops for URLs that are often crawled. With several hops, the primary effect is that it’s a bit slower for users. Online search engine just follow the redirect chain (for Google: up to 5 hops in the chain per crawl effort).”

Preferably, webmasters will want to aim for no greater than one hop.

What takes place when you include another hop? It decreases the user experience. And more than 5 present significant confusion when it comes to Googlebot being able to understand your website at all.

Repairing redirect chains can take a lot of work, depending on their intricacy and how you set them up.

But, the primary principle driving the repair work of redirect chains is: Simply make sure that you complete 2 actions.

First, get rid of the extra hops in the redirect so that it’s under five hops.

Second, carry out a redirect that redirects the former URLs

Prevent Redirect Loops

Reroute loops, by contrast, are basically a boundless loop of redirects. These loops happen when you reroute a URL to itself. Or, you inadvertently redirect a URL within a redirect chain to a URL that happens previously in the chain.

Example of a redirect loop: Reroute 1 > redirect 2 > redirect 3 > redirect 2

This is why oversight of website redirects and URLs are so important: You don’t want a circumstance where you carry out a redirect just to find out 3 months down the line that the redirect you created months back was the reason for problems since it created a redirect loop.

There are several reasons that these loops are disastrous:

Regarding users, redirect loops eliminate all access to a particular resource located on a URL and will end up triggering the browser to display a “this page has a lot of redirects” error.

For online search engine, reroute loops can be a significant waste of your crawl budget. They also produce confusion for bots.

This creates what’s described as a crawler trap, and the spider can not leave the trap easily unless it’s manually pointed elsewhere.

Fixing redirect loops is quite easy: All you have to do is eliminate the redirect triggering the chain’s loop and change it with a 200 OK operating URL.

Wish To Utilize JavaScript Redirects For SEO? Not So Quick …

Be cautious about creating JavaScript redirects because they might not be the very best solution for redirects, depending on what you have access to.

They ought to not be your go-to solution when you have access to other redirects due to the fact that these other types of redirects are preferred.

But, if they are the only option, you may not be shooting yourself in the foot.
