Do Google and other search engines have a constitutional right to control their own search results?

The answer is yes, at least in the opinion of UCLA law professor and First Amendment scholar Eugene Volokh.

In a report commissioned by the search giant, Volokh asserted that search results are a type of "opinion" based on what information the search engines believe would be most relevant to their users, according to PaidContent. Therefore, the results are protected by the First Amendment.
