Meta’s own guidance on lead ads puts the trade-off plainly: fewer multiple-choice questions bring more form submissions, and more of them typically bring higher-quality leads. We choose the number for your business and test it, rather than defaulting to the shortest form.
Meta also offers lead paths through Messenger, Instagram messages, WhatsApp and calls. They exist, and they suit some businesses; they are not the core of how we run Meta Ads for a trade business today.
Whichever path is chosen, the person is answered fast. Meta’s own advice on lead ads is that minimising follow-up time can improve lead quality. The lead path is only as good as the phone call after it.
