If you really have no choice, here are your main steps:

You moved your entire site to a new domain, and now, a few weeks later, you find out that your new domain is also the name of a Nickelback cover band. Naturally, you’re nervous. First, take a breath. Really assess whether the problem is as bad as you think. If so, this is similar to situation #3, but it’s often more dangerous because there are aspects of your domain and its history that can affect rankings independently of how well or poorly you’ve implemented 301-redirects.



Remove all 301 redirects from A→B.
Add a 301 redirect from B→A to the entire site.
Add self-referencing canonicals to all pages.
Re-point internal links to domain A.
Re-add domain A to Google Search Console (GSC)
Recreate the XML sitemap for domain A.

دوبارہ اشارہ کریں۔selectedڈومین A کے ان باؤنڈ لنکس۔
In this case, you will need a separate GSC profile. If you bangladesh number data the old one, re-add it and recreate your full XML sitemap. You will still want to submit important pages, just to speed up the process.

If you don't have access to domain B (perhaps the domain registration has expired, and someone has taken it), you won't be able to set up B→A redirects. The truth is, in this scenario, it's going to be a long and perhaps painful process. Secondary signals, like inbound links, are going to be very important in this scenario.
