Exactly. That's the fundamental risk of building on rented land. When your buyers come through Facebook Marketplace, every lead has value because visibility can vanish overnight the second Meta tweaks the algorithm or throttles your listing. The shops that are weathering this right now are the ones that already built a multi-node system independent of any single platform: customer text lists, missed-call text-back flows, Google Business profile presence, structured review generation, and automated win-back sequences for past buyers who are due again in 6-12 months. If you already have repeat customers, that's your strongest asset - Facebook can suppress reach at any trigger point, but an owned database is yours for the entire lifecycle.
For local businesses, the real advantage lies in capturing and owning that data early: set up a lead capture node right at the point of contact (call, message, walk-in), then route every response into a follow-up logic branch with time-based triggers. A simple reactivation campaign for tyre customers in that 6-12 month window can pull back churn before it happens. That's the kind of system that keeps revenue flowing even when Meta decides to disappear your listings for no real reason.
