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

Many modern websites utilize these kinds of redirects to reroute to HTTPS variations of web pages.

Finest Practices For SEO-Friendly JavaScript Redirects

Despite whether you are utilizing traditional redirects or JavaScript reroutes, there are numerous finest practices you must follow in order to not mess things up for SEO.

These finest practices include preventing redirect chains and redirect loops.

What’s the distinction?

Avoid Redirect Chains

A redirect chain is a long chain of redirect hops, referring to any situation 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 just process approximately 3 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 keep an eye out for is that you have less than 5 hops for URLs that are regularly crawled. With multiple hops, the primary effect is that it’s a bit slower for users. Online search engine just follow the redirect chain (for Google: approximately 5 hops in the chain per crawl attempt).”

Ideally, web designers will wish to go for no more than one hop.

What happens when you add another hop? It slows down the user experience. And more than five introduce significant confusion when it comes to Googlebot being able to comprehend your site at all.

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

But, the primary concept driving the repair work of redirect chains is: Simply make certain that you complete two steps.

First, eliminate the additional hops in the redirect so that it’s under 5 hops.

Second, carry out a redirect that reroutes the previous URLs

Avoid Redirect Loops

Redirect loops, by contrast, are basically an infinite loop of redirects. These loops take place when you reroute a URL to itself. Or, you inadvertently reroute a URL within a redirect chain to a URL that happens 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 situation where you implement a redirect only to discover 3 months down the line that the redirect you developed months back was the reason for problems because it developed a redirect loop.

There are numerous reasons these loops are devastating:

Regarding users, redirect loops remove all access to a specific resource located on a URL and will end up triggering the internet 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 also produce confusion for bots.

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

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

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

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

They need to not be your go-to solution when you have access to other redirects since these other kinds of redirects are chosen.

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