TikTok Ads vs Meta Ads: Which Should You Run?
TikTok Ads and Meta Ads solve different jobs — neither is universally better. Here's how the auctions, creative formats, and audiences actually differ.
Neither TikTok Ads nor Meta Ads is universally "better" — they run different auctions, reward different creative styles, and tend to fit different products and margins. The right answer depends on your niche, your creative volume, and what you measure, not a blanket platform ranking.
What's the core difference between the two?
TikTok is built around short, native-feeling vertical video where the algorithm rewards content that keeps people watching, so ads that look like organic UGC tend to blend in and perform. Meta (Facebook and Instagram) supports a wider mix of formats — image, carousel, and video — across placements like Feed, Stories, and Reels, and its targeting draws on a much longer history of user data. In practice, TikTok often rewards fresh, fast-hook video creative more aggressively, while Meta gives you more format flexibility and audience targeting depth.
Which platform is cheaper to run ads on?
There's no fixed price difference to quote — costs move constantly with auction competition, seasonality, and your own targeting and creative quality. Rather than comparing platforms by a dollar figure, compare them by outcome: pull your numbers into a ROAS calculator for each platform and let your own ROAS tell you where spend is actually working, since that will vary by product and time period.
Does creative style need to differ by platform?
Yes, generally. TikTok audiences respond to a raw, native, UGC-style feel more than to a polished traditional ad, and the platform's short attention window means the hook has to land in the first second — check your hook rate to see if it does. Meta audiences are more used to a range of formats, so a slightly more produced ad can still work well there, though a strong hook still helps everywhere. Keep TikTok creative vertical 9:16 with key elements inside the safe zones so nothing is covered by on-screen UI.
Do I have to pick just one platform?
Most advertisers eventually run both, since the platforms reach different pockets of the same audience and testing tends to reveal where your specific offer performs best. The practical constraint is usually creative supply — running two platforms well means needing more ad variations, tailored to each platform's native feel, without doubling your production time. This is the gap Polaris is built for: connect it to Claude once, describe the ad in plain chat, and generate UGC-style video variations for TikTok and Meta side by side, rendered live in the conversation and downloadable as a batch. See how AI UGC ads work or the walkthrough in generating ads inside Claude via MCP.
How should I decide where to spend first?
Start wherever your product and audience are the most natural fit, budget a real test on both if you can, and let ROAS and hook performance — not platform reputation — decide where you scale.
