Yes, they are more difficult to execute than standard redirects.
Preferably, you should use 301s, 302s, or 307-based redirects for implementation. This is the usual finest practice.
But … what if you do not have that level of gain access to? What if you have an issue with developing basic redirects in such a method that would be beneficial to the site as a whole?
They are not a best practice that you should be using specifically, however.
They are often utilized to inform users about changes in the URL structure, but they can be used for practically anything.
A lot of contemporary sites use these types of redirects to reroute to HTTPS variations of web pages.
Doing redirects in this manner is useful in numerous methods.
A Quick Introduction Of Redirect Types
There are a number of standard redirect types, all of which are useful depending on your situation.
Ideally, the majority of redirects will be server-side redirects.
These types of redirects come from 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 reroutes the majority of the time. Client-side redirects have some downsides, and they are generally ideal for more specific circumstances.
Client-side redirects are those where the web browser is what chooses the area of where to send out the user to. You must not need to use these unless you remain in a situation where you do not have any other option to do so.
Meta Refresh Redirects
The meta refresh reroute gets a bum rap and has a terrible credibility within the SEO community.
And for good reason: they are not supported by all browsers, and they can be puzzling for the user. Instead, Google recommends using a server-side 301 redirect rather of any meta refresh redirects.
Js redirects are probably not an excellent concept though.

These best practices include preventing redirect chains and redirect loops.
What’s the difference?
Prevent 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:
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 advises 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 several hops, the primary effect 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 greater than one hop.
What takes place when you include another hop? It decreases the user experience. And more than 5 present significant confusion when it comes to Googlebot being able to understand your website at all.
Repairing redirect chains can take a lot of work, depending on their intricacy and how you set them up.
But, the primary principle driving the repair work of redirect chains is: Simply make sure that you complete 2 actions.
First, get rid of the extra hops in the redirect so that it’s under five hops.
Second, carry out a redirect that redirects the former URLs
Prevent Redirect Loops
Reroute loops, by contrast, are basically a boundless loop of redirects. These loops happen when you reroute a URL to itself. Or, you inadvertently redirect a URL within a redirect chain to a URL that happens previously 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 important: You don’t want a circumstance where you carry out a redirect just to find out 3 months down the line that the redirect you created months back was the reason for problems since it created a redirect loop.
There are several reasons that these loops are disastrous:
Regarding users, redirect loops eliminate all access to a particular resource located on a URL and will end up triggering the browser to display a “this page has a lot of redirects” error.
For online search engine, reroute loops can be a significant waste of your crawl budget. They also produce confusion for bots.
This creates what’s described as a crawler trap, and the spider can not leave the trap easily unless it’s manually pointed elsewhere.
Fixing redirect loops is quite easy: All you have to do is eliminate the redirect triggering the chain’s loop and change it with a 200 OK operating URL.
They ought to not be your go-to solution 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 option, you may not be shooting yourself in the foot.
