However there are some scenarios where you simply can not prevent utilizing a JavaScript redirect.

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

What Are JavaScript Redirects?

JavaScript reroutes, basically, are among several methods of informing users and web crawlers that a page is offered in another place.

They are often utilized to notify users about changes in the URL structure, however they can be used for just about anything.

A lot of modern websites utilize these types of redirects to redirect to HTTPS versions of web pages.

Then, whenever someone checks out the initial URL, the web browser loads the JavaScript file and executes whatever code is within it. If the script includes directions to open a various URL, it does this automatically.

Doing redirects in this manner works in a number of ways.

For example, you can change URLs without by hand updating every single URL on your site. In addition, JavaScript redirects can make it much easier for search engines to discover your own material.

A Quick Introduction Of Redirect Types

There are several fundamental redirect types, all of which are helpful depending upon your scenario.

Server-side Redirects

Preferably, most redirects will be server-side redirects.

These kinds of redirects stem on the server, and this is where the server decides which area to redirect 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 reasons, you will likely use server-side redirects most of the time. Client-side redirects have some disadvantages, and they are generally appropriate for more particular scenarios.

Client-side Redirects

Client-side redirects are those where the internet browser is what chooses the location of where to send the user to. You ought to not need to use these unless you remain in a scenario where you do not have any other option to do so.

Meta Refresh Redirects

The meta revitalize redirect gets a bum rap and has a horrible reputation within the SEO neighborhood.

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

JavaScript Redirects

JavaScript reroutes, however, utilize the JavaScript language to send out instructions to the internet browser to reroute users to another URL. There is a dominating belief that JavaScript redirects cause issues for SEO.

Although Google does have great JavaScript rendering capabilities nowadays, JavaScript can still present concerns. This is true for other types of platforms likewise, such as Spotify and other ecommerce platforms.

If, however, you remain in a scenario where you can just use a JavaScript redirect as your only option, then you can just use JavaScript.

Also, Google’s Gary Illyes has actually mentioned as just recently as 2020 that JavaScript Reroutes “are most likely not an excellent concept.”

Js redirects are probably not a good idea though.

Finest Practices For SEO-Friendly JavaScript Redirects

No matter whether you are utilizing standard redirects or JavaScript redirects, there are a number of finest practices you should follow in order to not mess things up for SEO.

These finest practices consist of preventing redirect chains and redirect loops.

What’s the distinction?

Prevent Redirect Chains

A redirect chain is a long chain of redirect hops, referring to any scenario 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 only process as much as three redirects, although they have been understood to process more.

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

“It does not matter. The only thing I ‘d look out for is that you have less than 5 hops for URLs that are regularly crawled. With numerous hops, the primary result is that it’s a bit slower for users. Search engines simply follow the redirect chain (for Google: as much as 5 hops in the chain per crawl attempt).”

Ideally, web designers 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 substantial confusion when it comes to Googlebot being able to understand your site at all.

Fixing redirect chains can take a great deal of work, depending upon their complexity and how you set them up.

However, the main principle driving the repair of redirect chains is: Simply make certain that you complete two steps.

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

Second, implement a redirect that redirects the former URLs

Avoid Redirect Loops

Redirect loops, by contrast, are basically an unlimited 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 takes place earlier in the chain.

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

This is why oversight of website redirects and URLs are so important: You don’t want a scenario where you execute a redirect only to find out 3 months down the line that the redirect you developed months earlier was the reason for concerns since it developed a redirect loop.

There are numerous reasons why these loops are devastating:

Relating to users, reroute loops eliminate all access to a specific resource situated on a URL and will end up causing the internet browser to show a “this page has too many redirects” error.

For search engines, redirect loops can be a substantial waste of your crawl spending plan. They also produce confusion for bots.

This develops what’s described as a crawler trap, and the spider can not get out of the trap easily unless it’s by hand pointed somewhere else.

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

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

Beware about creating JavaScript reroutes since they may not be the best option for redirects, depending on what you have access to.

They should not be your go-to option when you have access to other redirects because these other types of redirects are preferred.

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