Quick tip: Post a few memes relating to your products on your page to see which is the most engaging. Google to find them. Pay someone to recreate them if you worry about copyright.
Boost the most engaging with “engagement” as goal. Low daily spend, broad targeting. See it as a tribute to the FB algo god.
This also good for making your brand more human to your audiences. Lure them with humor, make them lower their psychological guard.
