Guys I had a site that dropped from 8 to 70 a few days ago after I made some on page changes. Nothing dramatic - Just shortened the title and layout of the page. There were no changes made to outgoing links etc. Anyways, since then, I have published about 14 ezine articles, have got two PR6 Homepage highly relevant do follow backlinks to my site and it is still stuck at 70. Has not moved at all. Am I under a penalty and can I expect things to change any time soon?
