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

A lot of modern sites use these types of redirects to reroute to HTTPS versions of websites.

Then, whenever someone checks out the original URL, the web browser loads the JavaScript file and performs whatever code is inside of it. If the script consists of guidelines to open a different URL, it does this automatically.

Best Practices For SEO-Friendly JavaScript Redirects

Regardless of whether you are utilizing standard redirects or JavaScript reroutes, there are several best 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 distinction?

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 only process up to three redirects, although they have actually been known to process more.

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

“It doesn’t matter. The only thing I ‘d watch out for is that you have less than 5 hops for URLs that are frequently crawled. With numerous hops, the main 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 wish 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 5 present substantial confusion when it pertains to Googlebot having the ability to understand your website at all.

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

But, the main principle driving the repair work of redirect chains is: Just make sure that you total 2 steps.

Initially, remove the additional hops in the redirect so that it’s under 5 hops.

Second, execute a redirect that reroutes the previous URLs

Prevent Redirect Loops

Redirect loops, by comparison, are basically an infinite loop of redirects. These loops happen when you redirect a URL to itself. Or, you accidentally reroute 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 site redirects and URLs are so crucial: You don’t desire a circumstance where you implement a redirect just to discover 3 months down the line that the redirect you produced months ago was the cause of concerns since it produced a redirect loop.

There are numerous reasons these loops are disastrous:

Regarding users, redirect loops remove all access to a particular resource situated on a URL and will wind up causing the browser to show a “this page has too many redirects” error.

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

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

Repairing redirect loops is pretty 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.

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

Beware about producing JavaScript reroutes since they might not be the best service for redirects, depending upon what you have access to.
