Yes, they are more challenging to implement than standard redirects.
Ideally, you ought to utilize 301s, 302s, or 307-based redirects for application. This is the normal best practice.
But … what if you don’t have that level of access? What if you have a problem with creating standard redirects in such a method that would be advantageous to the site as a whole?
They are not a best practice that you must be using solely, however.
They are frequently used to notify users about modifications in the URL structure, but they can be used for just about anything.
Most contemporary sites use these kinds of redirects to redirect to HTTPS variations of web pages.
Doing redirects in this way is useful in numerous ways.
A Quick Introduction Of Redirect Types
There are numerous standard redirect types, all of which are advantageous depending on your scenario.
Preferably, a lot of redirects will be server-side redirects.
These types of redirects stem on the server, and this is where the server chooses which place 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 redirects the majority of the time. Client-side redirects have some drawbacks, and they are generally ideal for more particular scenarios.
Client-side redirects are those where the browser is what decides the place of where to send out the user to. You ought to not have to utilize these unless you’re in a circumstance where you do not have any other choice to do so.
Meta Refresh Redirects
The meta revitalize reroute gets a bum rap and has a dreadful reputation within the SEO neighborhood.
And for great reason: they are not supported by all browsers, and they can be confusing for the user. Instead, Google suggests utilizing a server-side 301 redirect rather of any meta refresh redirects.
Js redirects are probably not a great concept though.

These finest practices consist of preventing redirect chains and reroute loops.
What’s the distinction?
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:
Reroute 1 > redirect 2 > redirect 3 > redirect 4 > redirect 5
Why are these bad? Google can just process up to 3 redirects, although they have been known 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 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: as much as 5 hops in the chain per crawl attempt).”
Preferably, webmasters will wish to go for no greater than one hop.
What happens when you add another hop? It decreases the user experience. And more than 5 introduce significant confusion when it concerns Googlebot having the ability to comprehend your website at all.
Fixing redirect chains can take a great deal of work, depending on their complexity and how you set them up.
However, the primary principle driving the repair of redirect chains is: Simply ensure that you total two steps.
Initially, remove the additional hops in the redirect so that it’s under 5 hops.
Second, implement a redirect that redirects the previous URLs
Avoid Redirect Loops
Reroute loops, by contrast, are essentially a boundless loop of redirects. These loops happen when you reroute a URL to itself. Or, you mistakenly reroute 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 essential: You do not desire a scenario where you execute a redirect just to learn 3 months down the line that the redirect you developed months earlier was the reason for concerns due to the fact that it produced a redirect loop.
There are numerous reasons that these loops are dreadful:
Concerning users, reroute loops eliminate all access to a specific resource situated on a URL and will end up triggering the browser to show a “this page has a lot of redirects” error.
For online search engine, reroute loops can be a considerable waste of your crawl budget plan. They also produce confusion for bots.
This produces 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 elsewhere.
Repairing redirect loops is pretty simple: All you need to do is remove the redirect causing the chain’s loop and change it with a 200 okay working URL.
They should not be your go-to service when you have access to other redirects since these other kinds of redirects are preferred.
But, if they are the only alternative, you may not be shooting yourself in the foot.
