How to generate leads on Facebook: ads, forms, comments and DMs

To generate leads on Facebook, run ads with the Leads objective (Instant Forms, a landing page or Messenger), turn the questions people ask in your ad and post comments into DM conversations, qualify those leads with a few precise questions, and follow up within minutes. Quality depends less on the format than on the offer, the friction you add on purpose and the speed of your follow-up.

This guide compares the methods, walks through lead ads step by step, and shows how to use comments and DMs as a second lead source most advertisers ignore.

How to set up Facebook lead ads step by step

1. Create a campaign in Ads Manager and choose the Leads objective.

2. Pick the conversion location: Instant Forms, Website, Messenger, or a combination, depending on your offer.

3. Define the audience broadly enough for Meta to find people, and exclude existing customers when you can.

4. Create the form (for Instant Forms): choose the form type, add an intro that restates the offer, and ask two or three qualifying questions of your own (budget, timeline, need) on top of pre-filled contact fields.

5. Add your privacy policy link, which lead forms require, and a completion screen with a clear next step: book a call, download the guide, visit the site.

6. Connect your CRM or email tool, or at least set a routine to download leads daily, so no lead waits.

7. Launch and give it time to learn. Meta says an ad set generally needs about 50 optimisation events within seven days to leave the learning phase, so avoid editing it every day.

More volume vs Higher intent forms

Meta describes both in its help page on Instant Form types. Most complaints about "junk leads" from Instant Forms come from the frictionless default; a review step and one or two real questions filter out many accidental submissions.

Instant Form or landing page?

Instant Forms remove friction: that raises volume and lowers cost per lead, and also lets in people who barely read the offer. A landing page adds friction on purpose: people read the pitch before the form, so fewer sign up, but those who do already understand what they asked for.

The useful comparison is not cost per lead but cost per customer. Run both for the same offer, follow up the same way, and compare how many leads become meetings and sales. For simple offers (a guide, a discount, a newsletter), Instant Forms often win. For complex or expensive services, a landing page usually produces fewer, better leads.

Turn ad and post comments into leads

Every campaign produces a second lead source that sits in plain sight: comments. "Price?", "Is this available in Lyon?", "How long is the waiting list?" are people raising their hand in public.

1. Watch ad comments daily, including dark posts that never appear on your Page; our guide to monitoring comments on Facebook ads shows where to find them.

2. Reply publicly and briefly so other prospects see the answer, then continue in private.

3. Use a keyword call to action in organic posts and ads: "Comment GUIDE to get it by DM." An automation sends the link and a first qualifying question.

4. Qualify in DM with one or two questions, then hand serious prospects to a person.

5. Hide spam and scam replies under your ads: fake accounts that reply to your commenters steal the very leads you paid for.

Write an offer that attracts the right leads

The offer decides who fills in the form. A vague offer ("Get a quote") attracts curiosity; a specific one attracts intent. A strong offer usually combines:

• A clear outcome the prospect wants, in their own words.

• A specific method or format: a 20-minute audit, a sizing call, a personalised plan.

• A time frame or constraint: this month, five slots a week, before a deadline.

• Proof you can back up: reviews, case studies, certifications. Never invent numbers.

Compare "Get a quote for your kitchen" with "Book a free 20-minute kitchen layout call, with a 3D sketch sent within 48 hours". The second tells people what they get and filters out those who only want a price.

Follow up fast

A lead cools quickly: people forget they filled in a form, or talk to a competitor first. Set up the follow-up before launching the ads:

• Instant acknowledgement by email or DM with the promised resource or a booking link.

• A human contact within minutes during business hours for high-value leads.

• A short sequence for those who do not answer: two or three messages over a week, each with a reason to reply.

• A CRM record with the source (form, landing page, comment, DM) so you can compare channels.

Instagram, TikTok and LinkedIn follow the same logic with different formats; our cross-network lead generation playbook compares them.

Metrics that matter

Common mistakes

• Optimising for cost per lead alone. Cheap leads that never answer are expensive.

• Forms with no qualifying question. One well-chosen question saves hours of calls.

• Slow follow-up, especially on evenings and weekends when many forms are filled in.

• Ignoring ad comments, where buyers ask questions and scammers reply to them.

• Editing campaigns daily, which keeps them in the learning phase.

• Boosting posts for leads. Boosts optimise for engagement; use the Leads objective when you want leads.

Where Blabla fits

Blabla's automations work on the conversation side of Facebook lead generation, the part Lead Ads and your CRM never see. When someone comments your keyword under a Facebook or Instagram post or ad, Blabla sends the DM with your link and a first qualifying question. Questions about price, availability or delays get an AI answer drawn from the information you gave it, so no prospect waits for office hours. Prospects who show buying intent are tagged for your sales team, and scam replies under your ads are hidden before they reach your commenters. Comments and Messenger conversations share one inbox. Blabla does not replace Lead Ads or your CRM; it makes sure the leads who start in comments get an answer. Galeries Lafayette uses it for DM sales (see the case study).

Conclusion

Facebook lead generation works when three things line up: an offer specific enough to attract the right people, a format with the right amount of friction, and a follow-up faster than your competitors'. Run lead ads or landing pages for volume, treat comments and DMs as a lead source in their own right, and judge every channel on cost per customer, not cost per lead.
