Yes, they are more difficult to execute than basic redirects.
Preferably, you must utilize 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 a problem with developing standard redirects in such a way that would be advantageous to the website as a whole?
They are not a finest practice that you need to be using exclusively, nevertheless.
They are often used to inform users about changes in the URL structure, however they can be used for just about anything.
Most modern-day sites utilize these kinds of redirects to reroute to HTTPS variations of web pages.
Doing redirects in this way works in a number of methods.
A Quick Introduction Of Redirect Types
There are a number of fundamental redirect types, all of which are helpful depending upon your circumstance.
Preferably, the majority of redirects will be server-side redirects.
These types of redirects originate on the server, and this is where the server decides which area to redirect 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 reroutes the majority of the time. Client-side redirects have some downsides, 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 must not need to utilize these unless you’re in a scenario where you don’t have any other option to do so.
Meta Refresh Redirects
The meta refresh redirect gets a bum rap and has a terrible track record within the SEO neighborhood.
And for good factor: they are not supported by all browsers, and they can be puzzling for the user. Instead, Google advises utilizing a server-side 301 redirect rather of any meta refresh redirects.
Js redirects are most likely not an excellent idea though.

These best practices consist of preventing redirect chains and redirect loops.
What’s the distinction?
Prevent Redirect Chains
A redirect chain is a long chain of redirect hops, referring to any scenario 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 as much as 3 redirects, although they have actually 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 frequently crawled. With multiple hops, the primary result is that it’s a bit slower for users. Search engines simply follow the redirect chain (for Google: up to 5 hops in the chain per crawl attempt).”
Ideally, webmasters will wish to go for no greater than one hop.
What happens when you include another hop? It decreases the user experience. And more than five introduce significant confusion when it concerns Googlebot having the ability to comprehend your website at all.
Repairing redirect chains can take a great deal of work, depending upon their intricacy and how you set them up.
But, the primary principle driving the repair of redirect chains is: Simply make sure that you total two steps.
First, get rid of the extra hops in the redirect so that it’s under five hops.
Second, execute a redirect that redirects the former URLs
Prevent Redirect Loops
Reroute loops, by comparison, are essentially an unlimited loop of redirects. These loops happen when you reroute 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 website redirects and URLs are so important: You do not want a circumstance where you execute a redirect only to discover 3 months down the line that the redirect you created months back was the reason for concerns since it created a redirect loop.
There are several reasons why these loops are devastating:
Relating to users, reroute loops get rid of all access to a particular resource situated on a URL and will wind up triggering the browser to display a “this page has a lot of redirects” mistake.
For online search engine, reroute loops can be a significant waste of your crawl budget. They also create confusion for bots.
This creates what’s referred to as a crawler trap, and the crawler can not leave the trap easily unless it’s by hand pointed elsewhere.
Fixing redirect loops is quite easy: All you need to do is get rid of the redirect triggering the chain’s loop and replace it with a 200 okay functioning URL.
They need to not be your go-to service when you have access to other redirects because these other types of redirects are preferred.
But, if they are the only choice, you may not be shooting yourself in the foot.
