Searchers often come across Facebook "business" pages that were not actually created by the business or yelp.com results without reviews. So how Google detects and removes results from larger sites, when they don't have relevant content to a query?
Matt Cutts finds the question interesting and takes on it in the Webmaster Help video.
He says that Google in general looks at the value add or if there's some compelling value add, even at the page level. Algorithms are also written to reflect the same guidelines. Matt referred to a blog, he wrote in 2009 "Give Google Feedback on No Results Pages". People didn't like having empty review sites even at that time and the blog post contained a form that could be filled up to report such pages.
He adds, "We know that users get really angry when they are doing search and there's no search result on the page. And that's why we have talked about the issue under our technical guidelines (look at our quality guidelines). Google is willing to trim down these types of search results”.
Matt said that people can either report spam or show up at the forum to talk about such pages. They can still refer to the blog post and fill up the form.
So, next time you come across a no result search page, feel free to report it as spam, talk about it on Google forum, or browse through Matt's 2009 blog post.
