I think my website is penalized by big g. I really need your advice and help. Here are some info. 1. My website is still indexed and I can find my website by searching www.site.com or site.com 2. There is no changes in webmaster tool. 3. All rankings of keywords associated with my home page dropped in google search big time. Some of major keywords can't be found in first 25 pages. 4. Rankings of keywords associated with my inner pages dropped a lot as well and some of keywords used to rank on first page now can't be found in first 30 pages. 5. I didn't do any major SEO or link building work recently. I made about 500 forum profiles at the end of Oct, 2010 and my ranking went up until 2 days ago. Ranking disappeared in a sudden. 6. I also made a small change on each of page and changed some links but I don't this kind of minner change will trigger google to de-evaluate my website. What I feel right now is google on purposely filter my website for some search terms but I don't knw why. BTW, my website is a for retail purpose and only have 7 pages, very simple. I totally have 800 backlinks and I am at a niche which there is no that much of competition. My website lists all the products we sell in the retail store and list the store address. That's it. Can someone help me?
