What Are JavaScript Redirects?

JavaScript redirects, essentially, are among numerous techniques of informing users and web spiders that a page is available in another area.

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

Most contemporary websites use these types of redirects to redirect to HTTPS variations of web pages.

Then, whenever someone checks out the original URL, the browser loads the JavaScript file and executes whatever code is within it. If the script consists of instructions to open a various URL, it does this immediately.

Doing redirects in this manner works in numerous ways.

Server-side Reroutes

Ideally, most 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 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 utilize server-side reroutes the majority of the time. Client-side redirects have some drawbacks, and they are usually appropriate for more specific scenarios.

Client-side Redirects

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

Js redirects are probably not a great concept though.

Best Practices For SEO-Friendly JavaScript Redirects

Despite whether you are using standard redirects or JavaScript redirects, there are numerous finest 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, 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 only process as much as 3 redirects, although they have 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 frequently crawled. With numerous hops, the main result 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 attempt).”

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

What occurs when you add another hop? It decreases the user experience. And more than 5 present considerable confusion when it pertains to Googlebot being able to understand your site at all.

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

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

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

Second, carry out a redirect that reroutes the previous URLs

Avoid Redirect Loops

Reroute loops, by comparison, are essentially a limitless loop of redirects. These loops occur when you redirect a URL to itself. Or, you unintentionally reroute a URL within a redirect chain to a URL that happens earlier in the chain.

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

This is why oversight of website redirects and URLs are so important: You do not desire a situation where you implement a redirect just to discover 3 months down the line that the redirect you developed months back was the reason for concerns since it developed a redirect loop.

There are several reasons why these loops are dreadful:

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

For online search engine, reroute loops can be a considerable waste of your crawl spending plan. They likewise develop confusion for bots.

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

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

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

Be cautious about developing JavaScript reroutes due to the fact that they might not be the best option for redirects, depending upon what you have access to.

They should not be your go-to solution when you have access to other redirects because these other kinds of redirects are preferred.

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