My site was getting on the front page and top3 for my primary keywords for a few days this week and the last. They differed a bit datacenter to datacenter but I was very high for the first time. Suddenly now my site has gone from top3 to nothing in a matter of days. All the datacenters (most) that used to show me really high are letting go of my site one by one at a very high pace. Anyone notice this recently?
One of my very old site with lot of link building somehow managed to reach 2nd position from 8th last week. But its now seems to be gone forever..
The same for me, i'm thinking of redesigning and restructure my HTML to make it more seo friendly... I get more backlinks everyday but i'm still in da sandbox
One thing I am seeing is that if you site is newer than one year.. don't fight much..give it some time.. (an year) .. and keep building links.... and i m sure google will start understanding your efforts.
