We all used Facebook Hashtags during the last 3 months. We even celebrated their arrival on Facebook in the mid-June. But now that they're part of our Facebook posts for good, we can't help but wonder, do they really increase the reach of a post?
In a theoretical framework, hashtags allow you to extend your reach, since they allow you to attract bigger audience that might be looking for a similar content with yours, without even knowing of your existence up to then. That's how it worked on Twitter and it was indeed a successful use in many cases. However, in Facebook it didn't seem to work that way, at least until today.
