1. The domain has no any results when searching with “info:“
When you search about the domain you’re going to buy on Google using “info:example.com“, if there’s no any results then you should think about 2 reasons of that. First your domain was configured to redirect to another domain, this happen when you see another domain appearing on the search result pages. The redirection is not a penalty but it can cause your domain to lose all its backlinks. Second is that your domain has a temporary ban or “soft” ban

2. The domain has been banned from Adsense
Many people usually buy domains in order just to join Adsense, so that if that domain was banned from Adsense, they will not buy anymore. There’re many reasons that Google bans a domain such as it contains adult content, has low quality content, spamming or has trademark infractions. When you accidentally buy such kind of domain, it’s very hard to lift the ban and improve it in the future. You can check whether the domain was banned from this site. Just enter your domain in the text-box and press “Show Google Ads”, if you still see the ads, then it’s safe from Adsense and you can buy it.

3. The domain has been de-indexed from Google
If you search your domain you’re going to buy on Google with “site:example.com” and receive nothing, no any results showing your domain information then you may think about this sittuation, your domain was de-indexed by Google. This was happened because your domain had a crucial issue. Then it may takes you a lot of time to remove the penalty, usually months of hard work.

4. The domain was marked as adult
You can check the domain you’re going to buy by visiting this page and starting a check. This tool will help you see that whether your domain was marked as adult or not. If you have a plan to earn money with Adsense then it’s a big problem for you. Adsense doesn’t like adult.

I hope this helps
I have some concern on Google Adsense one, which text box you are considering to...because if we search in Google there will be no "Show Google ads" option.
