1. A whole ton of other site owners SEO'd their way to a better ranking than you;
2. You made a change in your site's structure or drastically changed content and Google re-indexed you;
3. You were working some trickery and Google found you out. They're not stupid, and won't think twice about blacklisting a site they find to be even close to dubious.
Ok it seems like google has my blog back at the top again for baking life xp. Seems so odd that one day it's not there then a next it's at the top again.
And also is Ask.com and google.com the same search as when I search baking life xp my blog is at the top of ask.com and google.com and aol.com ,but if I use bing my blog isnt on the top.
