However … what if you do not have that level of gain access to? What if you have an issue with producing standard redirects in such a method that would be helpful to the site as a whole?

This is where using JavaScript reroutes is available in.

They are not a best practice that you need to be using solely, nevertheless.

But there are some circumstances where you just can not avoid using a JavaScript redirect.

The following is a basic primer on JavaScript redirects, when to use them, how to use them, and best practices you should use when utilizing these kinds of redirects for SEO.

What Are JavaScript Redirects?

JavaScript redirects, basically, are one of numerous approaches of notifying users and web crawlers that a page is offered in another location.

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

Many contemporary sites utilize these kinds of redirects to redirect to HTTPS versions of web pages.

Then, whenever somebody checks out the original URL, the browser loads the JavaScript file and executes whatever code is within it. If the script includes instructions to open a various URL, it does this instantly.

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

For instance, you can switch URLs without manually upgrading every 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 numerous fundamental redirect types, all of which are useful depending on your situation.

Server-side Redirects

Preferably, a lot of redirects will be server-side redirects.

These kinds of redirects stem on the server, and this is where the server chooses which location 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 factors, you will likely use server-side redirects the majority of the time. Client-side redirects have some drawbacks, and they are typically appropriate for more specific circumstances.

Client-side Redirects

Client-side redirects are those where the browser is what chooses the area of where to send out the user to. You ought to not have to use these unless you’re in a situation where you don’t have any other alternative to do so.

Meta Refresh Redirects

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

And for great reason: they are not supported by all internet browsers, and they can be puzzling for the user. Instead, Google recommends using a server-side 301 redirect instead of any meta refresh redirects.

JavaScript Redirects

JavaScript reroutes, however, make use of the JavaScript language to send out directions to the web browser to reroute users to another URL. There is a prevailing belief that JavaScript redirects cause problems for SEO.

Although Google does have excellent JavaScript rendering abilities these days, JavaScript can still present concerns. This is true for other types of platforms also, such as Spotify and other ecommerce platforms.

If, however, you’re in a circumstance where you can just use a JavaScript redirect as your only choice, then you can just use JavaScript.

Likewise, Google’s Gary Illyes has actually stated as just recently as 2020 that JavaScript Redirects “are most likely not a good idea.”

Js redirects are probably not a great concept though.

Best Practices For SEO-Friendly JavaScript Redirects

No matter whether you are using 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 best practices consist of avoiding redirect chains and redirect loops.

What’s the difference?

Prevent 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:

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

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

What occurs when you include another hop? It decreases the user experience. And more than 5 present considerable confusion when it pertains to Googlebot having the ability to understand your site at all.

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

But, the primary principle driving the repair work of redirect chains is: Simply make certain that you complete 2 steps.

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

Second, implement a redirect that reroutes the previous URLs

Prevent Redirect Loops

Redirect loops, by comparison, are basically an infinite loop of redirects. These loops happen when you redirect a URL to itself. Or, you accidentally 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 website redirects and URLs are so important: You don’t desire a scenario where you execute a redirect just to discover 3 months down the line that the redirect you created months ago was the reason for issues because it developed a redirect loop.

There are a number of reasons these loops are disastrous:

Regarding users, redirect loops eliminate all access to a particular resource located on a URL and will end up causing the web browser to show a “this page has a lot of redirects” error.

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

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

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

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

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

They should not be your go-to solution when you have access to other redirects since these other kinds of redirects are preferred.

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