Welcome to WebmasterWorld Guest from 188.8.131.52
If I search for "online widgets" (plural), I receive a lot of results in the serps where the site is an "online widget" (singular) by itself and does not show many "online widgets" on the site (portal). And the keyword "online widgets" (plural) is nowhere on the website nor in the anchor text of the urls which link to this website. The website has nothing to do with the plural but it is listed in the top10 for the plural keyword.
I can find this strange "mix" of singular and plural websites in every business.
In my oppinion this is not correct and Google had made a difference between singular and plural before the BigDaddy update. Now there seems to be no difference and this is wrong because people do not receive what they are exactly searching for.
Maybe GoogleGuy can tell us if this will be fixed!?
