Anecdotally, based on my experience working with over 250 local businesses across the business spectrum, this doesn't reflect reality. A very small percentage of my clients "actively" use "organic" Facebook, an even smaller percentage use their ad platform (much higher usage of Google Ads). The ones that do (buy FB ads), typically do so through local "media company" who tack on their own fees, which in turn makes it a poor investment. I can count on one hand (out of hundreds) the number of our clients who effectively use Facebook. In fact, in the last couple of years, the number of businesses forgoing a "real website" and choosing Facebook (a common theme just a few years ago) has basically disappeared.
