Should service businesses run click-to-message ads instead of lead forms?

The real comparison is response model, not format

A lead form is asynchronous by design: they submit, you call back, everyone expects a gap. A message ad opens a live channel. The person who taps it is in a conversation now, and a reply an hour later reads as being ignored rather than as normal business process.

So the honest first question is whether someone can answer within minutes during the hours your ads run. If the answer is no, forms will outperform messaging even though messaging looks more modern.

Where messaging genuinely pulls ahead

• Jobs that need a photo. A homeowner can send a picture of the leak, the panel, the roof stain. That single image can qualify or disqualify a job faster than any form field.
• People who will not take a call. A meaningful share of consumers prefer text and simply do not answer unknown numbers. Messaging reaches them.
• Fuzzy scope. When the customer cannot name what they need, a few back-and-forth turns qualify better than a dropdown ever will.
• After-hours capture. A conversation can hold context overnight in a way a missed call cannot.

The costs nobody budgets for

Messaging moves the workload from a callback list to an inbox that has to be watched. That is a staffing decision. It also splinters your record of the customer: the conversation lives in a Meta inbox unless something pulls it into the CRM, which means your reporting, your call review and your customer history all have a hole in them.

Automation helps with the first response but does not solve the second. Whatever answers instantly still has to write the outcome back to your CRM so the lead is countable and the conversation is retrievable. Otherwise you have bought a channel you cannot measure.

How to choose without guessing

Run both against the same audience and the same offer, and compare on appointments set rather than on conversations started or forms submitted. Message ads will almost always show more engagements; that is not the question.

Also compare the time cost. If messaging produces similar appointment volume but consumes an hour of somebody's day per handful of conversations, that is a real expense even though it never appears in the ad account. Getting both channels into one outcome view is what marketing intelligence and customer intelligence exist to do.
