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

The majority of contemporary sites use these types of redirects to reroute to HTTPS variations of web pages.

Then, whenever someone checks out the original URL, the web browser loads the JavaScript file and carries out whatever code is inside of it. If the script includes guidelines to open a various URL, it does this immediately.

Doing redirects in this manner is useful in a number of ways.

There are numerous standard redirect types, all of which are beneficial depending upon your situation.

Server-side Reroutes

Preferably, many redirects will be server-side redirects.

These kinds of redirects come from on the server, and this is where the server chooses which location to redirect 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 the majority of the time. Client-side redirects have some drawbacks, and they are normally suitable for more specific circumstances.

Client-side Redirects

Client-side redirects are those where the internet browser is what chooses the area of where to send out the user to. You should not need to utilize these unless you’re in a scenario where you do not have any other alternative to do so.

Js redirects are probably not a good idea though.

Best Practices For SEO-Friendly JavaScript Redirects

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

These best practices consist of avoiding redirect chains and redirect 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 up to three redirects, although they have been understood to process more.

Google’s John Mueller suggests 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 often crawled. With numerous hops, the primary effect is that it’s a bit slower for users. Search engines just follow the redirect chain (for Google: approximately 5 hops in the chain per crawl effort).”

Ideally, webmasters will wish to go for no greater than one hop.

What happens when you include another hop? It decreases the user experience. And more than five introduce significant confusion when it concerns Googlebot having the ability to comprehend your site at all.

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

But, the main concept driving the repair work of redirect chains is: Simply ensure that you complete 2 steps.

First, remove the extra hops in the redirect so that it’s under 5 hops.

Second, execute a redirect that reroutes the former URLs

Avoid Redirect Loops

Redirect loops, by comparison, are essentially an infinite loop of redirects. These loops occur when you reroute a URL to itself. Or, you unintentionally redirect a URL within a redirect chain to a URL that takes place earlier in the chain.

Example of a redirect loop: Redirect 1 > redirect 2 > redirect 3 > redirect 2

This is why oversight of site redirects and URLs are so important: You do not desire a scenario where you carry out a redirect just to find out 3 months down the line that the redirect you produced months back was the cause of concerns due to the fact that it developed a redirect loop.

There are several reasons these loops are disastrous:

Concerning users, reroute loops eliminate all access to a specific resource situated on a URL and will end up causing the internet browser to display a “this page has too many 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 referred to as a crawler trap, and the spider can not get out of the trap quickly unless it’s by hand pointed somewhere else.

Repairing redirect loops is quite simple: All you have to do is get rid of the redirect triggering the chain’s loop and change it with a 200 OK operating URL.

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

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

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

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