They are typically used to notify users about modifications in the URL structure, however they can be utilized for almost anything.

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

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

Doing redirects in this way works in several ways.

Server-side Reroutes

Preferably, many redirects will be server-side redirects.

These types of redirects originate on the server, and this is where the server decides which location to reroute 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 utilize server-side reroutes most of the time. Client-side redirects have some downsides, and they are generally ideal for more particular situations.

Best Practices For SEO-Friendly JavaScript Redirects

Despite whether you are using conventional redirects or JavaScript reroutes, there are numerous best practices you should follow in order to not mess things up for SEO.

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

What’s the difference?

Avoid 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 approximately 3 redirects, although they have actually been understood to process more.

Google’s John Mueller advises 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 frequently crawled. With multiple hops, the main impact 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 attempt).”

Ideally, webmasters will want to go for no more than one hop.

What happens when you include 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 website at all.

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

But, the primary principle driving the repair of redirect chains is: Simply ensure that you complete 2 steps.

Initially, get rid of the extra hops in the redirect so that it’s under 5 hops.

Second, implement a redirect that redirects the previous URLs

Avoid Redirect Loops

Redirect loops, by comparison, are essentially an unlimited loop of redirects. These loops take place when you reroute a URL to itself. Or, you mistakenly redirect a URL within a redirect chain to a URL that takes place 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 crucial: You don’t want a circumstance where you execute a redirect only to find out 3 months down the line that the redirect you developed months ago was the reason for problems since it produced a redirect loop.

There are several reasons why these loops are dreadful:

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

For online search engine, reroute loops can be a considerable waste of your crawl budget plan. They also produce confusion for bots.

This produces 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.

Repairing redirect loops is quite simple: All you need to do is eliminate 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 Fast …

Beware about producing JavaScript redirects due to the fact that they might not be the best service for redirects, depending on what you have access to.

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

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