TikTok Ads vs Reels Ads: which converts more in 2026

"Should I put budget in TikTok Ads or in Reels Ads?" It is the question that shows up most in agency planning calls in 2026. The right answer is not "both" — it is it depends on the funnel, the ticket and the niche. Let us break it down with data.

The numbers below come from the audit of 38 client campaigns using Mais Social in Q1 2026, totaling R$ 4.8 million in media.

CPM: who costs more

• TikTok Ads BR: average CPM R$ 12.40.
• Reels Ads BR: average CPM R$ 18.70.

TikTok is 33% cheaper to deliver 1000 impressions. But low CPM only matters if the audience converts.

CTR: who generates more clicks

• TikTok Ads: average CTR 1.9%.
• Reels Ads: average CTR 1.4%.

TikTok wins too. Combining CPM + CTR, cost per click on TikTok is around R$ 0.65 vs R$ 1.34 for Reels.

Conversion: where the game turns

Here Reels leads consistently:

• TikTok Ads: post-click conversion rate 1.1%.
• Reels Ads: post-click conversion rate 2.4%.

Why? The Reels audience is majority over 30 years old, with credit card and online buying habit. The TikTok audience is still younger and the act of buying there is less natural.

ROAS by category

Low ticket e-commerce (up to R$ 100)

• TikTok Ads: average ROAS 2.8.
• Reels Ads: average ROAS 3.1.

Technical tie. TikTok wins in volume, Reels in margin.

Mid-ticket e-commerce (R$ 100-500)

• TikTok Ads: average ROAS 2.1.
• Reels Ads: average ROAS 3.8.

Reels clearly wins.

High-ticket e-commerce (R$ 500+)

• TikTok Ads: average ROAS 1.4.
• Reels Ads: average ROAS 4.2.

Reels dominates. High purchase decisions require higher trust, which Reels delivers.

B2B lead generation

• TikTok Ads: cost per lead R$ 38.
• Reels Ads: cost per lead R$ 24.

Reels wins because it reaches decision-makers more often.

App install

• TikTok Ads: cost per install R$ 4.80.
• Reels Ads: cost per install R$ 7.20.

TikTok clearly wins for youth apps.

Creative: what changes between platforms

TikTok

• Has to look UGC (organic content).
• First frame with eye-catching text.
• Hook in the first 1.5 seconds.
• Trending music (when licensed).
• Ideal duration: 9-15 seconds.

Reels Ads

• Can be a bit more polished.
• First frame can be product.
• Hook in the first 3 seconds.
• Original music or commercial track.
• Ideal duration: 15-30 seconds.

Using TikTok creative on Reels without adapting reduces performance by 20-30%. And vice versa.

When to run on both

It makes sense to run on both if:

• Monthly budget above R$ 30k (below that it spreads thin).
• You have capacity for dedicated creative per platform.
• The client sells a product with strong visual appeal.
• You want to test younger audiences (TikTok) vs current base (Reels).

When to focus on only one

Focus on only one when:

• Low budget (up to R$ 10k/month) — spreading kills tests.
• B2B client or high ticket — Reels.
• App client or 16-24 audience — TikTok.
• You do not have dedicated creative — choose the platform where the team is stronger.

Minimum technical setup

For either to work in 2026:

1. Pixel + Conversion API configured (on Meta) or TikTok Events API.
2. Product catalog synced.
3. At least 50 conversions/week for the optimization to learn.
4. 3-5 creatives per adset test.
5. Attribution window aligned with the client's purchase cycle.

Conclusion

TikTok Ads is cheaper for reach and clicks, but Reels Ads converts more — especially in mid/high ticket and B2B. For the agency without ideological battles, the rule is: young client + low ticket + reach, go TikTok. Client over 30 + mid ticket + sale, go Reels. Above R$ 30k of budget, run both with separate creatives.
