JavaScript reroutes, basically, are one of a number of approaches of notifying users and web crawlers that a page is readily available in another area.

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

Many contemporary sites utilize these types of redirects to reroute to HTTPS versions of web pages.

Then, whenever somebody checks out the initial URL, the web browser loads the JavaScript file and executes whatever code is inside of it. If the script consists of directions to open a different URL, it does this instantly.

Doing redirects in this way works in several methods.

For instance, you can change URLs without manually updating every single URL on your website. In addition, JavaScript redirects can make it simpler for online search engine to discover your own material.

There are several fundamental redirect types, all of which are beneficial depending upon your scenario.

Server-side Reroutes

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

These kinds of redirects stem on the server, and this is where the server decides which place 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 use server-side redirects most of the time. Client-side redirects have some drawbacks, and they are usually suitable for more particular situations.

Client-side Redirects

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

Meta Refresh Redirects

The meta refresh redirect gets a bum rap and has a dreadful reputation within the SEO neighborhood.

And for good reason: they are not supported by all browsers, and they can be confusing for the user. Rather, Google recommends utilizing a server-side 301 redirect instead of any meta refresh reroutes.

Js redirects are most likely not a good idea though.

Best Practices For SEO-Friendly JavaScript Redirects

No matter whether you are utilizing conventional redirects or JavaScript reroutes, there are several best practices you must follow in order to not mess things up for SEO.

These best practices consist of avoiding redirect chains and reroute loops.

What’s the difference?

Prevent Redirect Chains

A redirect chain is a long chain of redirect hops, referring to 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 as much as three redirects, although they have actually been known to process more.

Google’s John Mueller advises 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 often crawled. With multiple hops, the main result is that it’s a bit slower for users. Online search engine simply follow the redirect chain (for Google: up to 5 hops in the chain per crawl attempt).”

Ideally, webmasters will want to aim for no greater than one hop.

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

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

However, the primary principle driving the repair work of redirect chains is: Just ensure that you total 2 actions.

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

Second, carry out a redirect that reroutes the former URLs

Prevent Redirect Loops

Redirect loops, by contrast, are essentially a boundless loop of redirects. These loops happen when you reroute a URL to itself. Or, you accidentally redirect a URL within a redirect chain to a URL that happens earlier in the chain.

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

This is why oversight of website redirects and URLs are so essential: You don’t desire a circumstance where you execute a redirect only to learn 3 months down the line that the redirect you created months back was the reason for issues since it created a redirect loop.

There are numerous reasons why these loops are devastating:

Regarding users, redirect loops get rid of all access to a specific resource located on a URL and will end up causing the internet browser to show a “this page has too many redirects” mistake.

For online search engine, redirect loops can be a considerable waste of your crawl budget plan. They likewise 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 manually pointed elsewhere.

Repairing redirect loops is quite simple: All you need to do is get rid of the redirect causing the chain’s loop and change it with a 200 okay functioning URL.

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

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

They ought to not be your go-to option when you have access to other redirects due to the fact that these other types of redirects are preferred.

But, if they are the only choice, you may not be shooting yourself in the foot.
