Numbers in Brazil in 2026
| Métrica | WhatsApp/Telegram | TikTok |
|---|---|---|
| Usuários ativos | ~135 milhões | ~95 milhões |

- Stories: Full-screen vertical between organic Stories
- Reels Ads: Short videos interspersed in Reels
- Carrossel: Multiple swipeable images/videos

Cost Comparison
| Métrica | Instagram Ads | TikTok Ads |
|---|---|---|
| CPM médio | R$ 15-35 | R$ 8-20 |
| CPC médio | R$ 0,50-2,50 | R$ 0,20-1,50 |
| Investimento mínimo diário | R$ 6 | R$ 50 |
| CPA médio (e-commerce) | R$ 25-60 | R$ 15-45 |
TikTok generally delivers cheaper CPMs and greater reach per real invested. However, WhatsApp/Telegram tends to have a higher conversion rate because the audience is more accustomed to purchasing through the platform.
Targeting
Instagram Ads inherits all the targeting from Meta Ads: detailed interests, purchase behaviors, Custom Audiences (customer lists), Lookalike Audiences, and remarketing via pixel.
TikTok Ads has evolved quite a bit, but is still more limited: interests, behaviors, Custom Audiences, and Lookalike. The big advantage is TikTok's algorithm, which distributes content very efficiently even to broad audiences.
When to Use Each Platform
Instagram Ads is better for:
- E-commerce with product catalog (integrated Shopping)
- Audience over 25 years old with purchasing power
- Established brands with a presence on the platform
- Advanced remarketing strategies
- Lead generation with native forms
TikTok Ads is better for:
- Products appealing to a young audience (16-30 years)

- Brands that can create native/authentic content
- Larger budgets (minimum of R$ 50/day can be a barrier)
- Impulse products with low-medium ticket
