I have a few blogs that I promote in different niches, in one of my niches i have been trying for the last month to get to top of search with certain keywords, which I achieved, when Google did its last pages update a few weeks ago my site dropped from page 1 to page 5 so I went back to link building within my niche wrote a few articles and it has now gone back to page 2. There is one site that always seems to be on page one for this keyword and it takes abstracts of a few sentences from my sites and puts a link saying read more back to my post on my blog, so basically a auto blog, this site has no page rank and only has 2 back links from Google and these are not high PR back links but it seems that no matter what i do this site always out ranks me on Google for this keyword, the site does not even have the keyword in its meta or title and mine has all the relevant keyword in meta in title and has all relevant topic for the keyword even has H1 H2 etc in right places, this is really annoying me now my site is optimised fully has relevant back links with correct anchor texts etc and this site still out ranks me with no relevance, any tips of how to sort this problem would be appreciated
