Late last year I set up a link to one of the pages on my main site using a unique key word phrase. That key word phrase is not contained in the actual page.
This resulted in the page being listed on the first page on google for that key word phrase. It remained their until I last tested it about 3 months ago, but when I try it now the page is nowhere to be seen.
The site had a 50% drop in traffic as of yesterday. Some parts of it are OK, but other parts have dropped 100 or 200 positions. There seams to be a similar situation with the sites major competitors (though maybe not the same level of drop).
These pages seem to have been replaced by pages that contain the key word being searched for on the page, but are unlikely to have any pages linking to them with those key words.
Is it possible that somehow google has switched off the backlink/Anchor text part of their algo?
Does this mean it is a temporary situation?
