It has happend to me as well as of May 9th. I have consitently ranked in the top 10 for years with keywords like evening gowns, pageant gowns, ball gowns, evening dresses, formal dresses, mother of the bride dresses, etc... and now I am no where to be found on google - at all.
Around the same time yahoo dropped me so needless to say I was freaking out! I changed alot of my content (and didnt just lie out key phrases - like above) and yahoo put me back on. I tested it back and forth a few times and was able to see that it was content that yahoo was not liking but now is ok with...but google is not as "forgiving" shall we say with my site as yahoo has been.
So I have concluded that I was banned. HOw do you know that is it or if it was one of the other problems they list on thier site that it may be...Iit woudl be great if they coudl send you an email prior to doing so but I guess that will never happen.
In any event, once you are "banned" can or will they put you back on to be ranked, will they spider your site again, (as we are very well linked on many many sites) or do they just never let you back in....and if they do, when or is there something else I need to do other than what I did to satisfy yahoo.
Google was luckily and unfortunately a huge percentage of my business.
Help!!!!...I am a dress designer not a website designer...or programmer...any help or advise other than what is on googles site would be overly appreciated.
