But there are some circumstances where you simply can not prevent utilizing a JavaScript redirect.

The following is a fundamental guide on JavaScript reroutes, when to utilize them, how to utilize them, and finest practices you must utilize when making use of these types of redirects for SEO.

What Are JavaScript Redirects?

JavaScript reroutes, essentially, are among a number of methods of informing users and web spiders that a page is offered in another place.

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

Many contemporary websites use these kinds of redirects to redirect to HTTPS versions of websites.

Then, whenever somebody visits the initial URL, the browser loads the JavaScript file and carries out whatever code is within it. If the script consists of instructions to open a different URL, it does this instantly.

Doing redirects in this manner works in a number of ways.

For instance, you can change URLs without by hand upgrading every single URL on your website. In addition, JavaScript reroutes can make it easier for search engines to discover your own material.

A Quick Overview Of Redirect Types

There are several basic redirect types, all of which are advantageous depending on your scenario.

Server-side Reroutes

Ideally, many redirects will be server-side redirects.

These types of redirects originate on the server, and this is where the server chooses which area to reroute 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 factors, you will likely use server-side redirects the majority of the time. Client-side redirects have some disadvantages, and they are normally appropriate for more specific scenarios.

Client-side Redirects

Client-side redirects are those where the browser is what decides the area of where to send the user to. You must not have to utilize these unless you’re in a situation where you do not have any other alternative to do so.

Meta Refresh Redirects

The meta refresh reroute gets a bad rap and has a horrible credibility within the SEO community.

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

JavaScript Redirects

JavaScript reroutes, nevertheless, use the JavaScript language to send directions to the web browser to redirect users to another URL. There is a prevailing belief that JavaScript reroutes cause issues for SEO.

Although Google does have great JavaScript rendering abilities nowadays, JavaScript can still provide problems. This is true for other types of platforms also, such as Spotify and other ecommerce platforms.

If, however, you’re in a scenario where you can only utilize a JavaScript reroute as your only option, then you can only use JavaScript.

Likewise, Google’s Gary Illyes has actually specified as just recently as 2020 that JavaScript Redirects “are probably not a good concept.”

Js redirects are most likely not a good concept though.

Finest Practices For SEO-Friendly JavaScript Redirects

Despite whether you are utilizing standard redirects or JavaScript redirects, there are several finest practices you should follow in order to not mess things up for SEO.

These best practices include avoiding redirect chains and redirect loops.

What’s the difference?

Avoid 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 approximately three redirects, although they have been understood to process more.

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

“It does not matter. The only thing I ‘d watch out for is that you have less than 5 hops for URLs that are frequently crawled. With several hops, the primary result 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, webmasters will wish to aim for no more than one hop.

What happens when you include another hop? It slows down the user experience. And more than 5 introduce significant confusion when it pertains to Googlebot being able to understand your website at all.

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

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

Initially, remove the additional hops in the redirect so that it’s under five hops.

Second, carry out a redirect that redirects the previous URLs

Avoid Redirect Loops

Redirect loops, by comparison, are basically an unlimited loop of redirects. These loops occur when you redirect a URL to itself. Or, you unintentionally redirect a URL within a redirect chain to a URL that occurs 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 scenario where you carry out a redirect only to learn 3 months down the line that the redirect you produced months back was the reason for problems because it produced a redirect loop.

There are a number of reasons these loops are devastating:

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

For online search engine, redirect loops can be a significant waste of your crawl spending plan. They also produce confusion for bots.

This produces what’s described as a crawler trap, and the spider can not leave the trap quickly unless it’s manually pointed somewhere else.

Fixing redirect loops is pretty simple: All you need to do is remove the redirect causing the chain’s loop and replace it with a 200 okay working URL.

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

Beware about producing JavaScript redirects due to the fact that they may not be the very best solution for redirects, depending on what you have access to.

They should not be your go-to option when you have access to other redirects since these other types of redirects are chosen.

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