Meta Ads vs TikTok Ads vs YouTube Ads: Which Platform for Which Business in 2026?

TikTok is the cheapest per thousand impressions in 2026, at roughly $4 to $10 according to Trendtrack, ahead of YouTube ($9.20 to $14.85 depending on the format, according to Digital Applied) and Meta ($13 to $15, with Adamigo measuring a $13.48 average). A cheap impression is not a cheap customer, though: the same sources put the median ROAS at about 2.2x on Meta against 1.4x on TikTok.

CPM and ROAS figures are third-party numbers reported in 2026 (Adamigo, Trendtrack, Digital Applied) and vary widely by vertical, country and season. CPC figures are ranges we observe on the accounts we run, orders of magnitude for arbitrating a budget rather than a forecast for your account.

That spread is also why the platform question is a creative question before it is a media question. On Meta in particular, the creative decides delivery: the algorithm reads what the visual shows and who engages with it, so the account with the better creatives buys the cheaper impression inside the same auction.

Meta targets best for behavioral and retargeting use cases, YouTube for purchase intent read from Google Search, and TikTok for content affinity. In 2026 all three push advertisers toward broad targeting and automated audiences, so the settings matter less than they did and the creative carries more of the targeting.

Editorial ratings from the accounts we run. Meta dominates behavioral targeting and retargeting. YouTube excels at purchase intent through Google Search signals. TikTok reads content affinity better than either.

The biggest change since 2025 is that all three platforms now recommend handing the audience to the algorithm and competing on the creative instead. The details differ by platform.

Meta pushes Advantage+ campaigns and broad targeting as the default setup, and detailed interest targeting keeps shrinking: fine-grained interest segments have been retired in waves, and Advantage+ audience treats your manual selection as a suggestion rather than a boundary. The practical consequence is covered in how to build a Facebook ad that converts: the creative is what you actually control.

TikTok has made the organic post the ad unit. Spark Ads boost a creator's or a brand's existing video with its social proof intact, and TikTok Shop closes the purchase without leaving the app in the markets where it operates, which shortens the path from a viral video to a sale.

YouTube sells Shorts inventory as a vertical format in its own right, and Demand Gen campaigns spread one creative across YouTube, Shorts, Discover and Gmail with a single bid, which is how most of our YouTube consideration budgets now run.

Measurement is post-cookie everywhere: modeled conversions, server-side event APIs and aggregated reporting replace the deterministic pixel data of five years ago. Read your numbers as trends and orders of magnitude, and compare platforms on incremental lift rather than on last-click attribution.

Meta offers the widest format range (image, video, carousel, collection, Reels, lead forms), TikTok is video-only with In-Feed, TopView and Spark Ads, and YouTube splits between skippable and non-skippable in-stream, bumpers, Shorts and the Masthead. The formats that carry each platform are listed below.

The same creative, square then vertical

Before they are three ad products, these formats are three aspect ratios: 1:1 and 4:5 for the Meta feed, 9:16 for Reels, TikTok and Shorts, 16:9 for YouTube in-stream. Running one campaign across the three platforms means re-framing every creative three times, a production cost most budget plans forget, and the reason a cheap CPM is not automatically a cheap campaign.

Two shortcuts take most of that cost out. For vertical video, produce TikTok and Reels ads with AI from a script and a product image rather than a shoot. For the re-framing, one creative, every platform format is what Creative Resizer does: it re-cuts an approved creative into 1:1, 4:5, 9:16 and 16:9 with the composition adjusted, not just cropped.

Each platform rewards a different kind of creative: Meta a fast hook in 4:5 or 9:16 with statics still in the mix, TikTok a creator-shot vertical video with sound on, YouTube a brand-quality message delivered before the 5-second skip. Since August 2026 all three also require you to label AI-generated media.

The formats that win are documented platform by platform: the creative types that work on Meta rank UGC-style video, product demos and before/after first, while the UGC formats that carry TikTok are creator-shot testimonials, unboxings and day-in-the-life clips. AI-generated people are allowed on every platform as long as the label is on; the label costs nothing in the accounts we run when the creative is honest about what it is.

Meta wins for e-commerce, mobile apps and local businesses, TikTok for viral consumer products aimed at 18 to 34 year olds, and YouTube for B2B, education and considered purchases that need explaining. Audience size sets the ceiling; whether your buyer is inside it sets the answer.

Whatever the sector, the Meta leg of the plan follows the same six decisions; they are laid out in order in a Facebook ad that converts.

You need about $300 a month to learn anything on Meta, $50 a day per campaign on TikTok (the platform minimum), and $10 a day is enough to start on YouTube. The recommended ranges below are the ones we use with clients, orders of magnitude rather than rules.

At the CPMs reported in 2026, $1,000 buys roughly 100,000 to 250,000 impressions on TikTok, 67,000 to 109,000 on YouTube depending on the format, and 67,000 to 77,000 on Meta. The arithmetic is indicative: it divides $1,000 by the reported CPM, and your own CPM will move with the vertical, the country, the season and the quality of the creative.

Read the last column before the middle one. TikTok's 250,000 impressions are worth having at the top of a funnel; Meta's 67,000 are the ones most likely to end in a purchase, which is why the median ROAS reported by Digital Applied is 2.2x on Meta against 1.4x on TikTok despite a CPM two to three times higher.

Run a funnel across all three once you have more than about $3,000 a month to spend; below that, start on the single platform your business type points to and add the others as the account matures. The question is not "Meta or TikTok?" but "which stage does each one carry?"

A first split we use with clients who can fund all three: about 60% on Meta for conversion and retargeting, 25% on TikTok for reach and UGC-style video, 15% on YouTube for consideration. After 30 days, move budget toward whichever stage the account is starving, not toward the platform with the lowest CPM.
