The following is a fundamental guide on JavaScript redirects, when to use them, how to use them, and finest practices you must utilize when utilizing these types of redirects for SEO.

What Are JavaScript Redirects?

JavaScript reroutes, basically, are one of a number of approaches of informing users and web spiders that a page is available in another location.

They are typically used to inform users about modifications in the URL structure, but they can be utilized for almost anything.

A lot of modern sites use these types of redirects to redirect to HTTPS versions of web pages.

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

Doing redirects in this manner is useful in numerous methods.

For instance, you can change URLs without by hand updating every single URL on your website. In addition, JavaScript reroutes can make it simpler for search engines to discover your own material.

A Quick Summary Of Redirect Types

There are several basic redirect types, all of which are helpful depending on your circumstance.

Server-side Redirects

Ideally, a lot of redirects will be server-side redirects.

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

For SEO factors, you will likely use server-side reroutes most of the time. Client-side redirects have some downsides, and they are normally suitable for more specific scenarios.

Client-side Redirects

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

Meta Refresh Redirects

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

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

JavaScript Redirects

JavaScript reroutes, however, use the JavaScript language to send out directions to the browser to redirect users to another URL. There is a prevailing belief that JavaScript redirects cause problems for SEO.

Although Google does have great JavaScript rendering capabilities these days, JavaScript can still provide issues. This is true for other types of platforms also, such as Spotify and other ecommerce platforms.

If, however, you’re in a circumstance where you can only use a JavaScript redirect as your only choice, then you can just use JavaScript.

Likewise, Google’s Gary Illyes has stated as just recently as 2020 that JavaScript Reroutes “are most likely not a good concept.”

Js redirects are most likely not a great concept though.

Finest Practices For SEO-Friendly JavaScript Redirects

Regardless of whether you are using traditional redirects or JavaScript redirects, there are numerous best practices you must follow in order to not mess things up for SEO.

These finest practices consist of preventing redirect chains and reroute 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:

Reroute 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 known to process more.

Google’s John Mueller suggests 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 frequently crawled. With several hops, the main impact 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).”

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

What happens when you add another hop? It slows down the user experience. And more than five present significant confusion when it concerns Googlebot having the ability to understand your site at all.

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

But, the main concept driving the repair of redirect chains is: Simply make certain that you total two actions.

Initially, eliminate the extra hops in the redirect so that it’s under five hops.

Second, implement a redirect that redirects the previous URLs

Avoid Redirect Loops

Reroute loops, by contrast, are essentially a boundless loop of redirects. These loops occur when you reroute a URL to itself. Or, you unintentionally reroute a URL within a redirect chain to a URL that occurs earlier 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 essential: You do not want a scenario where you implement a redirect only to learn 3 months down the line that the redirect you produced months earlier was the cause of issues since it developed a redirect loop.

There are a number of reasons why these loops are dreadful:

Regarding users, redirect loops get rid of all access to a specific resource situated on a URL and will wind up causing the browser to show a “this page has too many redirects” mistake.

For search engines, reroute loops can be a considerable waste of your crawl budget. They likewise produce confusion for bots.

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

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

Want To Use JavaScript Redirects For SEO? Not So Quick …

Beware about producing JavaScript redirects due to the fact that they may not be the very best service for redirects, depending upon what you have access to.
