Very Strange Issue after site 301 redirection

[AniketS]

Hello,
So i have moved my old site to new domain via 301 redirection method on 6th January 2020. The Redirection was successful and new domain is also indexed on google but I am facing some strange issue.

Actually what is happening that my many URLs are missing from google for most of the good keywords.
Before they used to be on 1st page for the same keyword and now nowhere at google search for same keywords.

Another strange thing is happening with a few URLs. They are on top for few keywords and same URL is not showing for other main keywords. If we check on tools like Ahrefs and accuranker urls are showing for each and every keyword but not showing while searching manually on google.

What might be the reason? My new domain has past but I checked and everything was fine with it. There is no issue with new domain.

Any advice and suggestions will be greatly appreciated.

Google personalizes SERPs, are you accounting for that?
When you implemented your 301 redirect did you also make any change to the content or page code?

No haven't make any changes on the content.
I have changed the theme after 15 days.

There are small details that can be causing what you are seeing, but this sounds as if everything is going as planned except for what you personally observe in the results. Other people (and tools) see different results than you see, so have you tried viewing results on another device or using a different browser? It will take time for these new domain pages to settle into their positions, I would not be too worried in one month.

Do you still control the old domain to monitor access logs for your 301 changes?

Ya ya, I have checked with multiple browsers and devices but Urls for many keywords are not showing. They are showing on tools only.
Many keywords are still kept going from the SERP .

Basically how much time it takes?

Ya, i have old domain with me only.
