Two platforms. One budget. Here is a no-BS comparison so you can put your money where it actually makes money.
If you are selling physical products to 18-34 year olds and can produce raw, fast-paced video content, TikTok is probably your best first bet.
If you sell to a broader age range, need sophisticated retargeting, or sell high-ticket products, Facebook is still king.
Most brands making real money run both. But if you can only pick one, keep reading.
The differences are more nuanced than "TikTok is for kids and Facebook is for old people." Both platforms can work. The question is which one matches your product, audience, and creative capabilities.
Here is the actual data.
On paper, TikTok is cheaper. In practice, it depends.
TikTok has lower top-of-funnel costs but weaker retargeting. You get cheap clicks but converting them takes more work. Facebook costs more upfront but its retargeting pixel and lookalike audiences are years ahead.
The total cost-per-customer often ends up similar. Track full-funnel ROAS, not just front-end metrics.
Facebook has 20 years of data on its users. It knows what you buy, what you browse, what you like, and what you argue about in comments. Its targeting is surgical.
Lookalike audiences, detailed interest stacking, behavioral targeting, custom audiences from email lists, pixel data, and purchase history. Facebook has it all.
TikTok is catching up fast but it is still behind. TikTok targeting relies more on the algorithm learning from engagement. Broad targeting works better than detailed interests on TikTok. Let the algorithm figure out who wants your product based on how they interact with your content.
For retargeting, Facebook is significantly better. If your funnel depends on multi-touch attribution, Facebook should be your primary platform.

Facebook creative: polished works. Product photos, lifestyle images, branded videos, professional UGC. People expect ads on Facebook. Your ad can look like an ad and still convert.
TikTok creative: raw wins. If your ad looks like an ad, it dies. TikTok users scroll past anything that feels corporate. Your content must look like it was made by a real person. Phone-filmed, no filters, native editing, trending sounds, fast cuts.
You cannot run the same creative on both platforms. Repurposing a Facebook ad on TikTok (or vice versa) almost always underperforms native creative.
Budget time and resources for platform-specific content. It is non-negotiable.
Choose TikTok if:
- Your audience is 18-34
- Your product is under $50
- You can produce raw video content weekly
- You sell impulse-buy products
- You are in fashion, beauty, food, fitness, or gadgets
Choose Facebook if:
- Your audience is 25-55+
- You sell products over $50
- You need sophisticated retargeting
- You are in B2B, real estate, finance, or services
- Your creative is more polished and professional
Choose both if:
- You have the budget ($3K+/month) and creative capacity
- You sell products that appeal to a wide age range
- You can produce platform-specific content for each
The smartest media buyers use TikTok for cheap top-of-funnel awareness and Facebook for retargeting and conversion.
Here is the play: run broad TikTok ads to cold audiences. Get cheap views and clicks. Pixel those visitors. Retarget them on Facebook with stronger offers and social proof.
TikTok warms them up cheaply. Facebook closes the deal. This combo often beats running either platform alone.
Budget split: start with 60% Facebook, 40% TikTok. Adjust based on which platform delivers better full-funnel ROAS for your specific product.
The brands winning in 2026 are not picking sides. They are using each platform for what it does best.
