Google just tweaked its algorythm for search results after receiving a lot of backlash.  

Searching for “Holocaust” would show several racist websites before those with factual information.  

So Google rightly adjusted their algorythm to support more authority driven sites.  

This shouldn’t affect your site too much but now is the time to start pushing your bona fides of your industry.  Blogs and podcasts are a great way to do that.  Try to get linked on other sites.  Subscribers to your blog will definitely play a huge role.
