Has anyone else noticed that for certain keywords, their sites' homepage has started to appear as the top search result with a snippet from the post underneath it? In these cases, the homepage, actually appears to be a valid result for the search term that the user is searching for. When they click the link it takes them to the homepage. Its not normal Google behavior but it could explain a minor spike as people are searching for something else and click your link because it comes up in the results but then it takes them to the homepage instead of the direct article they were really looking for. While this is definitely odd behavior and may be indicative of another issue, for even a mildly popular site that would only explain a small portion of the increased traffic to the homepage?
