Two days agoI received an e-mail from Google telling that delphiarea using techniques that are outside of their quality guidelines, and will be removed temporarily from Google search results for at least 30 days.
I checked the site and saw the it is hacked. The hacker was put 100 advertisement links at the bottom of each page as hidden. I don't know what is the benefit of spreading those links as hidden.
Anyway, I just wanted to warn you about this issue. Regularly check source code of your pages on the browser to avoid such a problem.
