Yes, they are more tough to implement than basic redirects.
Preferably, you need to utilize 301s, 302s, or 307-based redirects for implementation. This is the typical finest practice.
However … what if you don’t have that level of gain access to? What if you have an issue with creating standard redirects in such a method that would be useful to the site as a whole?
They are not a best practice that you need to be using exclusively, however.
They are often utilized to inform users about modifications in the URL structure, however they can be used for just about anything.
Many modern-day 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 Introduction Of Redirect Types
There are numerous basic redirect types, all of which are useful depending on your circumstance.
Ideally, most redirects will be server-side redirects.
These kinds of redirects stem on the server, and this is where the server chooses which place 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 reasons, you will likely utilize server-side redirects most of the time. Client-side redirects have some drawbacks, and they are typically suitable for more specific scenarios.
Client-side redirects are those where the internet browser is what decides the place of where to send the user to. You ought to 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 revitalize redirect gets a bum rap and has an awful track record within the SEO neighborhood.
And for excellent reason: they are not supported by all web browsers, and they can be confusing for the user. Rather, Google advises utilizing a server-side 301 redirect instead of any meta refresh reroutes.
Js redirects are most likely not an excellent concept though.

These best practices include preventing redirect chains and reroute loops.
What’s the difference?
Avoid 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 only process up to three redirects, although they have actually been known to process more.
Google’s John Mueller recommends less than 5 hops per redirect.
“It doesn’t matter. The only thing I ‘d look out for is that you have less than 5 hops for URLs that are regularly crawled. With multiple hops, the primary effect is that it’s a bit slower for users. Search engines simply follow the redirect chain (for Google: as much as 5 hops in the chain per crawl attempt).”
Preferably, web designers will wish to aim for no more than one hop.
What takes place when you add another hop? It decreases the user experience. And more than 5 present substantial confusion when it concerns Googlebot being able to comprehend your website at all.
Repairing redirect chains can take a great deal of work, depending upon their complexity and how you set them up.
However, the primary principle driving the repair work of redirect chains is: Just ensure that you complete two steps.
First, eliminate the additional hops in the redirect so that it’s under 5 hops.
Second, carry out a redirect that redirects the previous URLs
Prevent Redirect Loops
Reroute loops, by contrast, are basically a boundless loop of redirects. These loops occur when you reroute 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: Redirect 1 > redirect 2 > redirect 3 > redirect 2
This is why oversight of website redirects and URLs are so essential: You don’t 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 problems due to the fact that it created a redirect loop.
There are numerous reasons these loops are disastrous:
Concerning users, redirect loops eliminate all access to a particular resource situated on a URL and will end up causing the web browser to show a “this page has too many redirects” mistake.
For search engines, redirect loops can be a considerable waste of your crawl spending plan. They also create confusion for bots.
This produces what’s described as a spider trap, and the crawler can not get out of the trap easily unless it’s manually pointed somewhere else.
Repairing redirect loops is pretty easy: All you need to do is eliminate the redirect triggering the chain’s loop and replace it with a 200 okay functioning URL.
They should not be your go-to service when you have access to other redirects due to the fact that these other kinds of redirects are preferred.
However, if they are the only alternative, you may not be shooting yourself in the foot.
