Facebook Ads vs TikTok Ads: Interest Targeting vs Creative-Driven Delivery

In short: Both are feed-based, interruption platforms with no query to target against, but they weight the inputs to delivery very differently. Facebook Ads still leans on audience definition, like interests, behaviors, and Advantage+ audience expansion, to decide who sees an ad, with creative as one input among several. TikTok Ads leans almost entirely on creative signal: the algorithm tests how a video performs and discovers the audience around what works, so a native, entertaining video will outperform a precisely targeted but polished brand film. TikTok creative also fatigues faster, so a plan built around one hero asset and months of runtime works on Facebook and stalls on TikTok. Choose Facebook when you have a defined audience and durable creative; choose TikTok when you can produce native-feeling video in volume and let the algorithm find the audience.

Facebook Ads

Buys interest- and behavior-based placements across Facebook's feed, Marketplace, Stories, and Reels, managed through Meta Ads Manager alongside Instagram inventory.

Paid placements on Facebook properties, managed in Meta Ads Manager and usually run in the same campaign as Instagram. It fits businesses creating demand for things people do not actively search for, since targeting rests on behavior rather than queries. The common misunderstanding is treating it as a keyword channel: on Meta the creative does most of the targeting work.

TikTok Ads

Buys short-form vertical video placements in the TikTok feed, sold at auction where creative quality drives most of the delivery outcome.

In-feed vertical video advertising where the algorithm rewards native, entertaining content over polished brand films. It suits advertisers who can produce creative in volume cheaply and want to reach people before they start searching. The main misunderstanding is creative lifespan: ads fatigue within days or weeks, so a plan built on one hero video and months of runtime will stall.

Side by side.

The differences that actually change what happens in your account.

	Facebook Ads	TikTok Ads
Primary delivery input	Audience definition, like interests, behaviors, and Advantage+ audience, alongside creative.	Creative performance signal first; the platform's discovery algorithm finds the audience around what works.
Creative format that wins	Static images, carousels, and video are all viable depending on placement.	Native, vertical, entertaining video; polished brand-style video underperforms against content that doesn't look like an ad.
Creative refresh cadence	Fatigue sets in over weeks to months depending on audience size.	Fatigue sets in within days to a couple weeks; needs a constant production pipeline.
Targeting precision	Interest and behavior categories, increasingly automated under Advantage+ audience.	Broad by design; the algorithm's own discovery does more of the audience-finding than manual inputs.
Minimum creative volume	Workable with a handful of ad variations rotated periodically.	Needs a steady stream of new videos to avoid frequency burnout on the account.
Audience skew	Broad across most age groups.	Younger-skewing, though the audience has broadened as the platform matured.
Production cost profile	Can work with a smaller set of higher-production assets.	Favors many cheap, fast, native-style videos over fewer expensive productions.
Failure mode	Precise targeting undermined by weak or repetitive creative.	One hero video stretched across months of runtime, fatiguing fast and starving delivery.

What actually separates them.

TikTok's delivery algorithm weights creative performance more heavily than audience targeting; Facebook still lets you define an audience and expects creative to perform within it, so the same targeting instinct that works on Facebook does less on TikTok.

TikTok ad creative fatigues on the order of days to a couple weeks; Facebook creative typically holds up for weeks to months before frequency erodes performance, so the two need very different production cadences.

Facebook's Advantage+ audience tools automate targeting expansion but still start from an advertiser-defined seed; TikTok's discovery model starts closer to broad and narrows based on engagement signal, inverting the starting point.

Polished, brand-style video is a neutral-to-negative signal on TikTok, where content that looks native to the platform outperforms it, while Facebook shows no comparable penalty for higher-production creative.

A single hero asset can carry a Facebook campaign for a meaningful stretch of runtime; the same approach on TikTok burns out quickly and requires a running production pipeline just to sustain delivery, not just to improve it.

Which one should you use?

Use Facebook Ads when

You have a defined audience you can describe by interest or behavior and want the platform to target against it.
Your creative production is lower-volume but higher-production, and it needs to hold up over weeks or months.
Your product needs more context or copy than a 15-second video can carry.
Your audience skews older or broader than TikTok's user base.

Use TikTok Ads when

You can produce native-feeling short video in volume, cheaply, on a recurring basis.
You want to reach people before they start searching for the category at all.
Your audience skews younger or you're testing entry into that demographic.
You're comfortable letting the algorithm find the audience rather than defining it manually upfront.

Common questions.

Why does my polished brand video underperform on TikTok?

Because the platform's users and its delivery algorithm both favor content that looks native to the feed, not like an interruption. A video shot to look like organic TikTok content usually outperforms a higher-production ad that reads as a commercial.

How often do I need new creative on TikTok versus Facebook?

TikTok creative typically fatigues within days to a couple weeks, so you need a running production pipeline. Facebook creative usually holds up for weeks to months before frequency erodes it, so the refresh cadence can be far slower.

Does TikTok Ads support interest-based targeting like Facebook?

It has targeting options, but the platform's discovery algorithm leans more heavily on creative engagement signal to find your audience than Facebook's does, so narrow manual targeting matters less than making creative that performs.

Can I repurpose the same video for both platforms?

You can, but expect it to underperform on whichever platform it wasn't made for. Facebook-shaped creative, static and text-forward, tends to read as an ad on TikTok, and TikTok-native creative can feel low-production or off-brand in a Facebook feed depending on the audience.
