Everyone likes to say they don't use Facebook, but they do. Or at least 10 people they know do.
Local businesses use Facebook relentlessly because, lots of times, it actually works to get people in the door or calling your number. Small businesses almost have to use its ad platform (in my opinion). I don't think local businesses can afford to look away from a top performer like this.
When I ran an escape room business, my fill-rate on weekends was typically dependent on whether or not I was spending money on Facebook. Google ads were second. Anything else barely had any ROI. Well - in the first few months of running the business, the local newspaper actually brought in some people, but nothing compared to my longer ad runs on Facebook.
I feel like this is a "you don't need Facebook" chant, but I feel that's not true for all industries, and I hope the take-away here is that maybe a huge online business with a giant ad budget can find other means, but if you are a small local business with $300 a month for marketing, I personally believe that you kind-of need Facebook.
