The usual complaint about Facebook in this trade is lead quality: forms from people outside the service area, fake phone numbers, tire kickers who never answer. Most of that comes from telling the algorithm to chase raw form volume. Meta learns whatever you reward, so if it only ever hears about submissions, it hunts for people who like submitting forms.
Feeding real outcomes back to Meta
The fix is to send better signals. The pixel and the Conversions API record site bookings, and your field service software can report which leads became a completed call or a sold system. When those events flow back, delivery shifts toward homeowners who resemble your paying customers. Instant forms get a qualifying question or two, such as ZIP code and whether the home is owned, which trims volume but raises the share your dispatcher can actually schedule.
Follow-up rules matter as much as the ads. Texting a lead requires clear consent under the TCPA, and the form wording should say that someone will call or text about the request. Many states also expect a license number on trade advertising, so the specialist checks what your jurisdiction requires before anything goes live. None of this is legal advice, only the checklist a careful campaign runs through.
