Hello I see 90% of "website value calculator" websites have adsense and i see is very friendly for Google.My question is: Did those kind of sites have good revenue with adsense?
I imagine that they would be difficult to monetize. They would need a ton of traffic in order to make anything.
These sites are not got approval from these domains. They have used other websites with rich and relevant content for approval. If you apply with these type of sites it will surely get rejected by AdSense.
