Today my autos4fast.com not getting any visitors... While checking i came to see that in webmastertools there is a message Pages on your site may not appear in Google search results pages due to violations of the Google webmaster guidelines.... So please help me how to remove this and also.... If i delete webmastertools should i get visitors same as before... Please reply ASAP...
Find out which rule you broke and then make any fixes you need, then let google know and it should start reappearing.
Webmaster tools is actually doing you a favor by telling you that you F*cked up with Google. Stop any on-page black hat, fix any site flaws, and do what webmaster tools says to do... Save the black hat for link building
I think the best way is, hmmm... find out if you can reach as many backlink as you can. It will strenghtened your position.
