Nobody follows a locksmith for fun. Social works for a trade as proof: real jobs, real vans and real reviews, plus local retargeting that keeps you in front of people who have already visited your site. We use it to support the calls your search ads and map listing already generate, not to chase likes.
Replace with a real client review. Ask after a job that went well — one honest sentence about the phone ringing more is worth more than a paragraph of praise.
