But there are some circumstances where you just can not prevent utilizing a JavaScript redirect.

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

What Are JavaScript Redirects?

JavaScript redirects, essentially, are one of numerous techniques of notifying users and web crawlers that a page is available in another place.

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

The majority of modern-day sites utilize these kinds of redirects to reroute to HTTPS variations of websites.

Then, whenever somebody visits the initial URL, the internet browser loads the JavaScript file and executes 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 works in numerous methods.

For instance, you can switch URLs without by hand updating every single URL on your site. In addition, JavaScript reroutes can make it much easier for online search engine to discover your own material.

A Quick Overview Of Redirect Types

There are numerous basic redirect types, all of which are helpful depending on your scenario.

Server-side Redirects

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

These types of redirects stem on the server, and this is where the server decides which location 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 the majority of the time. Client-side redirects have some disadvantages, and they are normally suitable for more specific circumstances.

Client-side Redirects

Client-side redirects are those where the internet browser is what decides the area of where to send out the user to. You must not have to use these unless you’re in a situation where you don’t have any other option to do so.

Meta Refresh Redirects

The meta refresh reroute gets a bad rap and has an awful credibility within the SEO neighborhood.

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

JavaScript Redirects

JavaScript redirects, nevertheless, make use of 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 these days, JavaScript can still present problems. This holds true for other types of platforms also, such as Spotify and other ecommerce platforms.

If, nevertheless, you remain in a situation where you can just utilize a JavaScript reroute as your only option, then you can only use JavaScript.

Likewise, Google’s Gary Illyes has actually specified as recently as 2020 that JavaScript Reroutes “are most likely not a good idea.”

Js redirects are probably not an excellent concept though.

Best Practices For SEO-Friendly JavaScript Redirects

No matter whether you are utilizing standard redirects or JavaScript reroutes, there are several finest practices you must follow in order to not mess things up for SEO.

These best practices include preventing redirect chains and reroute 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:

Reroute 1 > redirect 2 > redirect 3 > redirect 4 > redirect 5

Why are these bad? Google can just process up to three redirects, although they have been understood to process more.

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

“It doesn’t matter. The only thing I ‘d keep an eye out for is that you have less than 5 hops for URLs that are regularly crawled. With multiple hops, the main impact is that it’s a bit slower for users. Online search engine simply follow the redirect chain (for Google: up to 5 hops in the chain per crawl effort).”

Ideally, web designers will want to aim for no more than one hop.

What takes place when you include another hop? It slows down the user experience. And more than five present considerable confusion when it concerns Googlebot having the ability to comprehend your website at all.

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

However, the primary principle driving the repair of redirect chains is: Just ensure that you total two actions.

First, remove the extra hops in the redirect so that it’s under five hops.

Second, execute a redirect that redirects the former URLs

Prevent Redirect Loops

Redirect loops, by comparison, are basically an unlimited loop of redirects. These loops happen when you reroute a URL to itself. Or, you accidentally reroute 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 site redirects and URLs are so crucial: You do not desire a circumstance where you implement a redirect just to learn 3 months down the line that the redirect you created months ago was the cause of issues due to the fact that it created a redirect loop.

There are several reasons why these loops are disastrous:

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

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

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

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

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

Beware about developing JavaScript reroutes due to the fact that 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 option when you have access to other redirects due to the fact that these other kinds of redirects are preferred.

However, if they are the only alternative, you might not be shooting yourself in the foot.
