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

A lot of contemporary websites use these types of redirects to redirect to HTTPS variations of websites.

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

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

A Quick Overview Of Redirect Types

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

Server-side Redirects

Ideally, most redirects will be server-side redirects.

These types of redirects stem on the server, and this is where the server decides which area to reroute 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 typically suitable for more particular scenarios.

Client-side Redirects

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

Meta Refresh Redirects

Finest Practices For SEO-Friendly JavaScript Redirects

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

These best practices include avoiding redirect chains and redirect loops.

What’s the distinction?

Prevent Redirect Chains

A redirect chain is a long chain of redirect hops, describing any situation 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 only process up to three redirects, although they have actually been known to process more.

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

“It does not matter. The only thing I ‘d watch out for is that you have less than 5 hops for URLs that are often 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).”

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

What occurs when you add another hop? It slows down the user experience. And more than 5 introduce considerable confusion when it pertains to Googlebot being able to understand your site at all.

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

But, the main principle driving the repair work of redirect chains is: Simply ensure that you total 2 actions.

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

Second, carry out a redirect that reroutes the former URLs

Prevent Redirect Loops

Reroute loops, by contrast, are basically an infinite loop of redirects. These loops happen when you redirect a URL to itself. Or, you inadvertently redirect 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 site redirects and URLs are so essential: You don’t desire a scenario where you carry out a redirect only to learn 3 months down the line that the redirect you created months ago was the reason for concerns since it produced a redirect loop.

There are several reasons these loops are dreadful:

Regarding users, reroute loops remove all access to a particular resource located on a URL and will wind up causing the web browser to show a “this page has a lot of redirects” mistake.

For online search engine, redirect loops can be a substantial waste of your crawl budget plan. They likewise produce confusion for bots.

This creates what’s referred to as a spider trap, and the spider can not leave the trap quickly unless it’s manually pointed somewhere else.

Fixing redirect loops is quite easy: All you need to do is remove 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 Fast …

Be cautious about developing JavaScript redirects since they may not be the very best solution for redirects, depending on what you have access to.

They should not be your go-to service 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 might not be shooting yourself in the foot.
