JavaScript redirects, basically, are among a number of techniques of notifying users and web spiders that a page is available in another place.

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

The majority of modern websites utilize these types of redirects to redirect to HTTPS variations of websites.

Then, whenever someone visits the initial URL, the browser loads the JavaScript file and executes whatever code is inside of it. If the script consists of directions to open a various URL, it does this immediately.

Doing redirects in this way is useful in numerous ways.

A Quick Summary Of Redirect Types

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

Server-side Reroutes

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

These types of redirects stem on the server, and this is where the server decides which area 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 downsides, and they are typically suitable for more particular scenarios.

Client-side Redirects

Client-side redirects are those where the browser is what decides the place of where to send the user to. You should not need to use these unless you remain in a circumstance where you do not have any other alternative to do so.

Meta Refresh Redirects

Finest Practices For SEO-Friendly JavaScript Redirects

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

These finest practices include preventing redirect chains and redirect loops.

What’s the distinction?

Avoid Redirect Chains

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

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

“It does not 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 several hops, the main effect is that it’s a bit slower for users. Online search engine simply follow the redirect chain (for Google: as much as 5 hops in the chain per crawl attempt).”

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

What happens when you include another hop? It decreases the user experience. And more than five present substantial confusion when it concerns Googlebot having the ability to understand your website at all.

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

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

Initially, eliminate the additional hops in the redirect so that it’s under 5 hops.

Second, execute a redirect that reroutes the previous URLs

Avoid Redirect Loops

Reroute loops, by contrast, are basically an unlimited loop of redirects. These loops take place when you redirect a URL to itself. Or, you inadvertently reroute a URL within a redirect chain to a URL that takes place earlier in the chain.

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

This is why oversight of site redirects and URLs are so crucial: You don’t want a situation where you implement a redirect just to find out 3 months down the line that the redirect you produced months ago was the cause of problems because it produced a redirect loop.

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

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

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

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

Fixing redirect loops is quite easy: All you have to do is remove the redirect causing 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 reroutes since they may not be the very best service 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 due to the fact that these other types of redirects are chosen.

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