Wow this could be big! Google has adjusted search results into giving, what they make most money for instead of what really is most helpful to the consumer. There is also evidence that they are manipulating the search results based on other factors. Now unfortunately, for Google, anytime they adjust the search algorithm, people will adjust how they create content and try to "get at the top" of the search results. There is an easy way to "fix" this. It is allow users to control the search results. Suppose the search engine had 100 automated factors. These could be things like website reputation, number of ads, sexual content, location, writing level ect. If I do not want sexual content I could take a slider and turn it down. If I don't want ads. I could turn commercial content down. If I want something academic, intelligent I could slide writing level up. By re-weighting each factor, it would be hard for hijack the results. I think something like this could overtake Google.
