Instant forms are cheap to fill out, which is exactly the problem. Here is how to make the form do qualification work.
Meta will happily send you hundreds of form fills. Left alone, most of them are people who tapped a button on a bus. The remedy is friction placed deliberately.
Use the higher-intent form type, add a confirmation step, and ask two qualifying questions that a tire-kicker will not bother answering — property type and rough timeline are usually enough. Volume drops, booked jobs go up.
State the price band in the creative. A card that reads "Roof replacements from $9,800" repels the wrong audience for free, which is cheaper than repelling them with a salesperson's time.
Then attach retargeting. Most home-service purchases involve a partner conversation between the first click and the decision, and the retargeting sequence is what survives that conversation.
