Why is the site on the new domain not showing up in google?

Question

Google

I made a website, everything is fine, when I entered keywords, search engines even found it. But the customer bought himself a new domain. I re-uploaded it, and now even when you enter the full path in the search bar, nothing is displayed, but by keywords it finds the old site, which is disabled. What is the problem? ATP in advance

Answer 1

Because it hasn't been indexed. Perhaps the search engine perceives it as a mirror of the old, redirect from the old to the new. I also advise you to specify the old site in the webmaster panels as a mirror of the new one.
