Invisalign’s In-Ad Quiz Slashes Acquisition Costs While Boosting Qualified Leads

TikTok campaigns that convert rather than merely collect likes have already produced staggering results for brands like Invisalign and Toyota Germany. The secret lies in building genuine lead qualification directly into the ad experience.

Anny Havercroft, TikTok’s global head of product marketing communications, has spent five years developing the platform’s B2B lead generation playbook. Her mission involves helping advertisers transform TikTok from a discovery platform into a complete demand engine. The patterns she’s identified separate high-performing campaigns from those that simply chase vanity metrics.

**Readiness beats reach**

TikTok’s billion-plus monthly users tempt marketers toward treating the platform purely as an awareness play. Havercroft pushes back on that assumption. The platform’s value stems from engagement signals, not raw impressions. Those signals include watch duration, likes, shares, and product searches. Brands that interpret these indicators effectively generate genuinely qualified leads.

Invisalign demonstrated this principle masterfully. Its Smile Quiz, embedded directly within the ad unit, let potential customers assess their candidacy without leaving TikTok. Form submissions jumped 28%. Acquisition costs dropped 11%. Landing page completion rates soared 133% higher than previous campaigns.

**Format flexibility matters**

Smart marketers avoid forcing users down rigid paths. TikTok offers multiple native formats spanning the entire funnel. TopView ads capture attention immediately upon app launch. Consideration ads reach audiences who’ve already interacted with similar brands or content. Commerce tools like TikTok Shop close the deal without requiring external navigation.

Spot Pet Insurance leveraged this layered approach effectively. Instead of optimizing solely for form fills, the company tracked quote requests and completed payments. The outcome: 23% more qualified leads at a 19% lower cost.

**Nurturing prevents ghosting**

Havercroft draws a sharp comparison between abandoned leads and modern dating ghosting. It makes no sense, she argues, to invest in lead generation and then let prospects go cold.

Toyota Germany’s approach proves the value of follow-through. The automaker built content tailored to each stage of the car buying journey, from browsing videos to booking test drives. Every TikTok lead flowed into existing CRM nurture sequences. The result was a 38% reduction in acquisition costs.

Creator-led content can outperform brand assets. Spain’s Gana Energia tested creator content against internally produced materials through an A/B framework. Creator content won decisively. Total lead volume increased 632%, while cost per lead fell 64.5%.

The path forward requires clean data connections between TikTok campaigns and CRM systems like HubSpot. That integration enables two-way data flow, allowing brands to optimize toward genuine conversion potential rather than surface-level engagement.
