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

Many contemporary sites utilize these kinds of redirects to redirect to HTTPS variations of websites.

Then, whenever someone checks out the initial URL, the browser loads the JavaScript file and executes whatever code is within it. If the script consists of directions to open a different URL, it does this instantly.

Server-side Redirects

Preferably, the majority of redirects will be server-side redirects.

These kinds of redirects come from on the server, and this is where the server chooses which place 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 factors, you will likely use server-side reroutes most of the time. Client-side redirects have some disadvantages, and they are generally suitable for more specific circumstances.

Finest Practices For SEO-Friendly JavaScript Redirects

Regardless of whether you are using traditional redirects or JavaScript reroutes, there are numerous best practices you need to follow in order to not mess things up for SEO.

These finest practices include preventing redirect chains and reroute loops.

What’s the difference?

Avoid Redirect Chains

A redirect chain is a long chain of redirect hops, describing 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 just process as much as 3 redirects, although they have actually been understood 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 main impact is that it’s a bit slower for users. Online search engine simply follow the redirect chain (for Google: approximately 5 hops in the chain per crawl effort).”

Preferably, web designers will wish to go for no greater 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 concerns Googlebot being able to understand your website 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 principle driving the repair of redirect chains is: Simply make certain 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 essentially a limitless loop of redirects. These loops happen when you reroute a URL to itself. Or, you inadvertently redirect 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 crucial: You don’t want a circumstance where you implement a redirect only to learn 3 months down the line that the redirect you developed months ago was the cause of problems since it created a redirect loop.

There are numerous reasons these loops are disastrous:

Relating to users, reroute loops get rid of all access to a specific resource located on a URL and will wind up triggering the browser to show a “this page has too many redirects” error.

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

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

Fixing redirect loops is quite simple: All you have to do is remove the redirect causing the chain’s loop and replace it with a 200 OK operating URL.

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

Be cautious about producing JavaScript reroutes because they might not be the best option for redirects, depending upon 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 kinds of redirects are preferred.

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