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

Many contemporary websites use these types of redirects to redirect to HTTPS versions of web pages.

Then, whenever somebody goes to the original URL, the web browser loads the JavaScript file and carries out whatever code is within it. If the script consists of guidelines to open a different URL, it does this immediately.

There are numerous fundamental redirect types, all of which are helpful depending upon 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 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 utilize server-side redirects most of the time. Client-side redirects have some disadvantages, and they are generally ideal for more specific circumstances.

Best Practices For SEO-Friendly JavaScript Redirects

Regardless of whether you are using traditional redirects or JavaScript redirects, there are numerous best practices you must follow in order to not mess things up for SEO.

These best practices consist of preventing 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 3 redirects, although they have actually 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 look out for is that you have less than 5 hops for URLs that are regularly crawled. With numerous hops, the primary impact 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 want to aim for no more than one hop.

What happens when you include another hop? It decreases the user experience. And more than 5 present significant confusion when it comes to Googlebot having the ability 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 principle driving the repair work of redirect chains is: Just make certain that you complete 2 actions.

First, get rid of the extra hops in the redirect so that it’s under five hops.

Second, implement a redirect that reroutes the former URLs

Prevent Redirect Loops

Reroute loops, by contrast, are basically an infinite loop of redirects. These loops happen when you redirect a URL to itself. Or, you unintentionally redirect a URL within a redirect chain to a URL that occurs previously 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 important: You do not want a circumstance where you carry out a redirect only to discover 3 months down the line that the redirect you developed months earlier was the reason for issues because it produced a redirect loop.

There are numerous reasons why these loops are devastating:

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

For search engines, reroute loops can be a considerable waste of your crawl spending plan. They also develop confusion for bots.

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

Fixing redirect loops is quite simple: All you have to do is eliminate the redirect triggering 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 redirects due to the fact that they might not be the very best solution for redirects, depending on what you have access to.

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

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