should i replace my domain? its been 2 months
this would be a good idea only if your current domain is blacklisted or heavily penalized in some way that makes it unrecoverable for google.
The fact that you got deindexed could be attributed to many reasons, such as:
- your site is new, and google doesn't trust it yet
- your content is bad and google doesn't like it yet
- your site is poorly optimized, so google doesn't like it
- your page (the one that got deindexed) is considered orphaned because it has no internal links pointing to it, so point a few internal links to it from other pages that are relevant to that page
- etc...
Basically, you need to audit your site and optimize it for google, by implementing things like...
- make it load fast and be mobile friendly (these 2 are very important things when it comes to technical SEO)
- make it easy to navigate, intuitive, and make sure that all important pages are maximum 3 clicks away from the homepage (ideally, 1 or 2 clicks only, but 3 will work too)
- implement schemas where appropriate
- silo it properly (although, this should have been done in the site planning phase, if you've already built the site in a poorly structured way you'll now have to work even more to structure it properly, and that's assuming that google have not already recorded it with the bad structure and refuse to reward it after you improve it, which could happen)
But anyway, replacing the domain won't do you any good if the domain is still clean and good in general. You only replace domains that are penalized or banned / blacklisted by google, otherwise you keep improving your current domain until the problems get fixed.
Also, you should check your GSC for the reasons that your pages got deindexed, google tend to tell you the exact reason for why they de-indexed your pages, so check google's recommendations and work on those first...
