One of my websites were on 2nd page for the last week for 4 keywords, but suddenly for the last 2 days it disappeared from Google. I was very happy when I saw it on second page, first place on 24th March 2011 for 4 keywords.
Keywords were
increase youtube views
buy youtube views
increase youtube video views
buy youtube video views.
But the next day when I woke up, it suddenly disappeared. I did a thing this week, I changed some link builders of me that were doing a lot of articles and blog comments, and I gave it to a good new SEO that I saw his good credentials at freelancer.com. I fear had any of the previous guys did anything black hat towards me?
Or what happend to my site, now for no keywords its seen on any of the pages. I didn't know what to do.
Please help me
