Now another question is Google mad? or Link building is nothing? site which is on top of Google uk against keyword Letting Agents has just 2 anchor text links, what is that? Link building is just use less thing? Google sale 1st position ? or those links with OBl 200 and 148 are enough and all my links are useless?
Without URL, Competition analysis of top 20 sites, Backlinks, PR etc etc it is really tough to say or come to a conclusion, regarding what's wrong. Ranking with hardcore backlinking is same as it was ever before. But yes, these days Google caffeine gives preference to most recently indexed information or pages.
There are a lot of criterion that Google takes when assigning rankings..though its difficult to tell the weightage that it gives to different factors. Backlinks are very much important even today .. though even I am experiencing a lot of fluctuation for my website rankings which is quite frustrating. Still I would say keep making quality back links that helps..
