Lead Ads

Lead ads are ads with a built-in form. Users tap the ad, a form opens right inside the app, and their contact details are often pre-filled from their profile. On Meta the format is called Instant Form, on LinkedIn Lead Gen Form. Google Ads and TikTok also offer their own lead forms.

Pros

• Less friction: No page switch, no load time, pre-filled fields.
• Strong on mobile: Fewer users drop off, especially on smartphones.
• Quick to set up: No landing page needed.

Cons

• Lower quality: Because filling out the form is so easy, people with little interest sign up too.
• Less context: Users don't see your website and know less about your offer.
• Data stays in the platform: Without an integration, leads sit in the ad account and reach sales late.

Example

A real estate agent tests two variants with a $1,000 budget each. Lead ads bring in 80 leads ($12.50 per lead), the landing page 35 leads ($28.57 per lead). After eight weeks, the lead ads have produced 2 listings and the landing page 4. So the landing page costs $250 per deal, the lead ads $500.

Evaluating lead ads properly

With lead ads, the ad platform only measures the form submission. Whether the leads can be reached and actually buy only becomes clear in sales. That's why you should compare lead ads by deals and revenue, not by cost per lead.

LeadMetrics imports leads from Meta Instant Forms and LinkedIn Lead Forms and attributes them to the right campaign and ad. Connected to HubSpot, Close or your payment provider, you see which forms actually drive revenue. Through the Conversion API you can send closed deals back to the platform so it optimizes for qualified leads. See how this works in practice for real estate.

Common mistakes

• Forms that are too short: One extra qualifying question often lowers volume but raises quality.
• Slow follow-up: People who signed up in the app barely remember it a few days later.
