TikTok Ads vs Meta Ads: Where Should You Spend?

Short answer: choose TikTok if your product is visual, your buyers are on TikTok, and you can produce native short videos regularly; it often delivers cheaper attention and fresh audiences. Choose Meta (Facebook and Instagram) if you need dependable conversion optimization, retargeting, lead forms and a broad age range. If you can afford it, test both on the same goal and compare cost per sale or qualified lead, not cost per click.

Below we compare the two platforms side by side and show how to run a fair test. For specialist help, see our TikTok ads and Meta ads services.

TikTok Ads vs Meta Ads at a glance

Which platform is cheaper?

On impressions, TikTok usually is. WordStream's 2026 data puts typical TikTok CPMs at roughly $4–$10, while third-party benchmarks put average Meta CPMs in the US above $20. On clicks, both can be cheap: LocaliQ/WordStream benchmarks show Meta traffic-campaign clicks averaging well under $1.

But the number that matters is cost per customer. TikTok viewers are often in entertainment mode, so conversion rates can be lower; Meta's audiences and optimization can convert more reliably for some offers. The only honest answer is to test. See how much TikTok ads cost and how much Facebook ads cost for full benchmarks.

How does creative differ between TikTok and Meta?

Creative is the biggest lever on both platforms, but the rules differ:

On TikTok:

• Hook in the first one to two seconds.
• Real people talking to camera, filmed on a phone.
• Trends, sounds and native text styles.
• Ads that look polished and corporate get skipped.

On Meta:

• Short video still leads, especially Reels placements.
• Static images and carousels can work well, especially for retargeting and offers.
• Clear product benefits and social proof.
• More tolerance for designed, branded ads.

Many brands produce one batch of creator-style videos and adapt them for both. See how to repurpose one video across TikTok, Reels and Shorts and Facebook ad creatives that convert.

Targeting and tracking: what's the difference?

Both platforms now rely heavily on broad targeting and algorithmic delivery: you describe your goal and supply good creative, and the system finds buyers. The quality of the conversion data you send back matters more than detailed interest targeting.

• TikTok: install the TikTok Pixel and Events API.
• Meta: install the Meta Pixel and Conversions API.

Without server-side tracking on both, you'll undercount results and the algorithms will optimize on incomplete data.

How do you run a fair TikTok vs Meta test?

1. Pick one goal (purchases, qualified leads, booked calls) and define success in money terms (target cost per acquisition or ROAS).
2. Use comparable creative concepts adapted to each platform.
3. Give each platform enough budget for at least two to four weeks. TikTok needs above $20 a day per ad group; Meta's learning phase works best with about 50 conversions a week per ad set.
4. Don't change things daily. Let the learning phase finish.
5. Compare on the same attribution rules, and watch blended results: total new customers against total spend. TikTok often drives later searches and direct visits that last-click reporting misses.
6. Decide and reallocate. Shift budget toward the platform with the lower cost per customer, and keep testing the other with new creative.

Should you run both?

Often yes, once you have the budget and creative capacity. A common pattern is:

• TikTok for discovery and new audiences
• Meta for prospecting plus strong retargeting of people who engaged anywhere
• Google Search to catch people who later search your brand or product

This is how many e-commerce brands structure spend; see our e-commerce marketing strategy guide.

A worked example

A DTC skincare brand splits $10,000 a month between Meta and TikTok for six weeks, using the same six creator-style concepts adapted for each platform. TikTok delivers a lower CPM and strong reach among 18–34-year-olds, with a slightly higher cost per purchase. Meta delivers more purchases at a lower cost per purchase, helped by retargeting. During the test, branded Google searches rise, mostly in weeks when TikTok spend is highest. The brand keeps TikTok for prospecting and new-audience reach, uses Meta for both prospecting and retargeting, and judges both on blended new-customer acquisition cost. (Illustrative.)

Budget split starting points

Adjust monthly based on cost per customer, not CPM or CPC.

Creative production tips for both

• Film vertical (9:16), with key content in the centre safe zone
• Shoot several hooks per script
• Keep captions on-screen
• Make TikTok versions feel native (trends, sounds, faster pacing)
• Keep Meta versions clear on offer and product

The bottom line

TikTok tends to win on cheap, attention-grabbing reach; Meta tends to win on mature conversion tools and retargeting. Your customers, product and creative capacity decide which comes first. Test both fairly on the same business goal, then put money where customers cost least.
