I am about to purchase a .com domain directly from its owner.
- Domain is 20yrs old.
- Domain is not used for anything in particular, just a few ads on it.
- Not able to track backlinks as looks like robots.txt blocks crawling.
- Domain is not on an email blacklist.
What else should I check, ask the owner about in order to reduce the risk of buying domain with a bad history, SEO etc?
