Two of my former first-page-sites have disappeared from the 40 first pages after Brandy. However I noticed following for both sites. When searching for widget1 I get 2 million found, mine (www.widget.xx) is nowhere to be seen. However when searching for +widget I get 3.7 million found and my site (www.widget.xx) is on place 6.
Same is true with the other domain of mine, eventhough the competion on that keyword is much less, about 200.000 pages.
In both cases I have the keyword=domain and with the national topdomain matching the language of the keyword. I have a fair amount of backlinks and PR4.
Any clue how to work around this? Most of my other sites built with same technique are still on first page for relevant keywords.
