They are often utilized to notify users about changes in the URL structure, however they can be used for just about anything.

Many contemporary websites utilize these kinds of redirects to reroute to HTTPS versions of web pages.

Then, whenever somebody visits the initial URL, the web browser loads the JavaScript file and performs whatever code is inside of it. If the script consists of instructions to open a various URL, it does this instantly.

Doing redirects in this way works in a number of methods.

There are several basic redirect types, all of which are useful depending on your circumstance.

Server-side Redirects

Preferably, most redirects will be server-side redirects.

These kinds of redirects come from on the server, and this is where the server decides which area to redirect the user or 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 use server-side redirects most of the time. Client-side redirects have some drawbacks, and they are typically appropriate for more specific scenarios.

Client-side Redirects

Client-side redirects are those where the browser is what decides the location of where to send the user to. You must not have to utilize these unless you remain in a scenario where you don’t have any other option to do so.

Meta Refresh Redirects

The meta refresh reroute gets a bum rap and has an awful credibility within the SEO neighborhood.

Finest Practices For SEO-Friendly JavaScript Redirects

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

These finest practices include avoiding redirect chains and redirect loops.

What’s the distinction?

Prevent Redirect Chains

A redirect chain is a long chain of redirect hops, referring to any circumstance 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 just process as much as three redirects, although they have 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 regularly crawled. With several 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 attempt).”

Preferably, web designers will wish to aim for no greater than one hop.

What happens when you add another hop? It slows down the user experience. And more than five present significant confusion when it comes to Googlebot being able to understand your site at all.

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

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

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

Second, implement a redirect that reroutes the former URLs

Prevent Redirect Loops

Reroute loops, by comparison, are basically a boundless loop of redirects. These loops occur when you reroute a URL to itself. Or, you mistakenly reroute a URL within a redirect chain to a URL that occurs previously 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 essential: You don’t want a situation where you carry out a redirect just to find out 3 months down the line that the redirect you developed months earlier was the reason for concerns since it created a redirect loop.

There are numerous reasons why these loops are dreadful:

Relating to users, reroute loops eliminate all access to a particular resource located on a URL and will wind up causing the internet browser to display a “this page has too many redirects” mistake.

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

This produces what’s referred to as a spider trap, and the crawler can not leave the trap quickly unless it’s by hand pointed somewhere else.

Fixing redirect loops is quite easy: All you need to do is eliminate the redirect causing the chain’s loop and change it with a 200 okay functioning URL.
