Yes, they are more tough to execute than basic redirects.
Preferably, you need to use 301s, 302s, or 307-based redirects for application. This is the normal best practice.
However … what if you don’t have that level of gain access to? What if you have an issue with developing basic redirects in such a way that would be helpful to the site as a whole?
They are not a finest practice that you ought to be utilizing specifically, however.
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.
Doing redirects in this manner works in a number of ways.
A Quick Overview Of Redirect Types
There are several basic redirect types, all of which are advantageous depending on your scenario.
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 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.
Js redirects are most likely not a good concept though.

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.
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.
