If you want to check whether the expired domain has a Google penalty, the best way is to verify it in Google Search Console first.
After adding the domain to Search Console, go to the “Manual Actions” section. If the domain has a penalty from Google, it will usually appear there. If you see “No issues detected,” then there is likely no manual penalty.
You can also check a few additional things:
- Search the domain in Google using: site.com to see if pages are indexed.
- Review the backlink profile using tools like Ahrefs or SEMrush to check for spammy links.
- Look at the domain’s history on the Wayback Machine to see what kind of content it previously hosted.
These checks should give you a good idea of whether the domain is clean or potentially problematic.
