The majority of contemporary sites utilize these kinds of redirects to reroute to HTTPS variations of websites.

Then, whenever someone visits the original URL, the web browser loads the JavaScript file and performs whatever code is within it. If the script consists of guidelines to open a different URL, it does this immediately.

For SEO factors, you will likely use server-side redirects the majority of the time. Client-side redirects have some disadvantages, and they are generally appropriate for more specific scenarios.

Finest Practices For SEO-Friendly JavaScript Redirects

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

These finest practices include preventing redirect chains and reroute loops.

What’s the distinction?

Prevent Redirect Chains

A redirect chain is a long chain of redirect hops, describing any scenario 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 three redirects, although they have been understood to process more.

Google’s John Mueller recommends less than 5 hops per redirect.

“It doesn’t matter. The only thing I ‘d watch out for is that you have less than 5 hops for URLs that are regularly crawled. With numerous hops, the main impact 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).”

Preferably, webmasters will wish to aim for no more than one hop.

What occurs when you add another hop? It decreases the user experience. And more than five present significant confusion when it comes to Googlebot having the ability to comprehend your website at all.

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

However, the main principle driving the repair work of redirect chains is: Simply ensure that you total two actions.

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

Second, implement a redirect that redirects the former URLs

Prevent Redirect Loops

Redirect loops, by contrast, are essentially an unlimited loop of redirects. These loops happen when you reroute 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 crucial: You do not want a scenario where you carry out a redirect only to find out 3 months down the line that the redirect you produced months ago was the cause of issues due to the fact that it developed a redirect loop.

There are a number of reasons why these loops are dreadful:

Concerning users, reroute loops remove all access to a specific resource situated on a URL and will wind up triggering the web browser to display a “this page has too many redirects” error.

For search engines, redirect loops can be a substantial waste of your crawl budget. They also produce confusion for bots.

This produces what’s described as a spider trap, and the spider can not get out of the trap quickly unless it’s by hand pointed elsewhere.

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

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

Be cautious about creating JavaScript redirects due to the fact that they may not be the very best service for redirects, depending on what you have access to.
