Imagine that Google assigns categories to every webpage or website that it visits. You can see categories like those for sites in Google’s local search. Now imagine that Google has looked through how frequently certain keywords appear on the pages of those websites, how often those pages rank for certain query terms in search results, and user data associated with those pages.
One of my local supermarkets has a sushi bar, and they may even note that on their website, but the keyword phrase [sushi bar] is more often found upon and associated with documents associated with a category of “Japanese Restaurants” based upon how often that phrase tends to show up on Japanese Restaurant sites, and how frequently Japanese restaurant sites tend to show up in search results for that phrase.
Since Google can make a strong statistical association between the query [sushi bar] and documents that would fall into a category of “Japanese restaurants,” it’s possible that the search engine might boost pages that have been categorized as “Japanese restaurants” in search results on a search for [sushi bar]. My supermarket [sushi bar] page might not get the same boost.
That’s something that a Google patent granted earlier this week tells us.
