I love tracking shit. Because of that, I've been tracking how popular the "paleo" idea has been the past couple years. My business is spending too much time on paleo websites, and business is good! Here are where popular paleo websites rank out of all domains on the internet:
Here are things I've noticed: while "paleo" has been getting more popular, the top few sites have become mega more popular. This includes sciency sites, recipes cites, and this weirdo site called paleohacks. Also, I noticed that some awesome sites don't have as much traffic as I'd expect (e.g. thatpaleoguy). What strikes you about these rankings? Note that very few health/nutrition websites that are actually useful are in the top 1,000. Mercola is #500...I know he ruffles feathers for many, but he at least doesn't offer standard advice.
Note that this ranking is based on the flawed Alexa methodology, and not all sites are included because of difficulty gathering info.
