Website migration has to be a well planned smooth process, for which you will need to plan the redirects correctly. If redirects are ignored, users get frustrated when they find the requested links not working, or if it does not take them to the proper destination.
Google also cannot tell where the page got moved to, without redirects. It will start showing the 404s page not found error, which is okay with search engine bots, but the index will start falling down, and along with it the link power will also vanish soon.
Therefore it is necessary to have WordPress redirect planned for all those pages that are to be migrated to a new domain address. Mistakes can usually happen because developers, designers, and SEO team, do not work in sync with each other.
Deadlines were given more importance, so many backend aspects got overlooked. Just the visible things gained importance, but it was assumed that redirects could be fixed later on. Or the redirection task was given to non-SEO staff with hardly any knowledge about the significance of properly redirecting webpages. Such irresponsible actions can mess up the website migration.
Certain redirection rules must be followed for successful website migration. It will help to avoid site migration errors.
Create 1-to-1 redirects
Creating a 1-to-1 redirect is very crucial. If you feel that, why waste time in redirecting 1-to-1 page, so you redirect all pages to your home page. This is an irrelevant redirect. It tells Google that page A or page B has been migrated to Page X, which is a home page. When all pages lead to the homepage, Google will treat it as soft 404, which doesn’t count.
Lookout for redirect chains
Redirect chains get formed when URL A gets redirected to URL B and again and again to another location. A chain gets created, but Google advises developers to shorten the redirect chains as much as they can. Instead of redirecting from A, B, C, and D, you can go straight from the requested source A to destination D.
Lookout for loops
When a redirect points to A then to URL B and C and back to URL A – It makes a loop. It never gets resolved, because it seems like a dog chasing its tail. You might even have to reset WordPress to resolve the problem.
Do 404 cleverly!
Google takes pages showing 404s out from the index, so if the pages had high link juice you lose its benefits. 404s let the pages die along with their rich backlinks. It does hamper your ranking. Make sure you use 404 only if you are not losing benefits, or if there is nothing relevant to redirect this page to.
Prioritize URLs valuable to SEO
URLs with good rankings drive in plenty of organic traffic, so make sure you redirect them as a priority. It is necessary to ensure everyone gets redirected. If it is not possible, at least you will have the most crucial ones with great SEO value handled before the launch.
You might be certain that everything is done right, but there are chances where you may have made redirecting mistakes, so testing is necessary before the stating phase.
