Quoting what you said in your post
A lot of site have a great database bitcoin wallet address generated with privet key
And quoting what you said in your website.
This website doesn't actually have a database of all private keys, that would take an impossible amount of disk space. Instead, keys are procedurally generated on the fly when a page is opened. The page number is used to calculate which keys should be on that page.
Aside from lying about your website being a database for private keys what it's look like is you are just generating random characters in your website hoping that you will hit the jackpot into getting an active wallet. I don't know if you are doing this to fool people for traffic or you are actually trying to commit a crime here.
