I have been on the net since 2001 with one personal website or another and I have definitely enjoyed success with Google and Google Adsense for most of that time. My current successful site just took a giant hit with the algorithm change (or at least I think it took a hit). In mid-December I moved the site to a new virtual private server from a share hosting account for better performance. Somehow during the move the DNS got messed up and I noticed in Webmaster Tools that the Googlebot was indexing the IP address for my site and the associated name for the site (http://highperformancehvac.com).
The problem has been corrected but I think in the process I was hit by the Algorithm change. My traffic spiraled from 5 to 6 thousand visitors a day to a little over a thousand a day. I do not do any bad things to game the system.; I make sure my pages are properly optimized with good keyword density. I constantly promote the site and try to get back links by emailing other webmasters and all my articles are original written by myself. I have had copyright issues with others trying to hijack my articles but I report it as soon a I find it which is very difficult to do (finding the images and content that has been hijacked is not an easy task).
I hope there will be a re-evaluation of my site and you will give me the credit I once had because the content I write truly is unique and considered the best out there for what I write. I have many trade journals asking to write for them but I simply do not have the time. Please make a correction Google? Thanks
