Google product search has wrong keyword matching, Google has recently banned all advertisers from having ads which sell PageRank, When I searched in Google for "buy pagerank links" to test any potential violators I saw their product search showing results of Cobra 2 way radio results for Pagerank keywords. PageRank is most widely called in short form PR and the site has PR in their product name and this makes google's algorithm through a completely wrong result.

you will see that when i search " buy pagerank links" I see cobra electronics ranks on top of google results and "PR" is highlighted.

This page sells all cobra electronics products after I click on any result I land on this product page

I just wonder how much irrelevant traffic this site is getting, Probably a bonus for them, I hope Google fixes this since its not good for their users.
