TikTok vs Reels vs YouTube Shorts for Brand Campaigns

How do TikTok, Reels and YouTube Shorts compare?

Platform usage comes from Pew Research Center’s 2025 survey of U.S. adults. (Pew Research Center) Those are platform-wide figures, not just short-form viewers, but they show how wide YouTube’s audience reach is.

The same idea performs differently on each platform, and that’s useful information. INFLUENCE runs creators across TikTok, Reels and Shorts in one campaign, so you can see where each idea works best.

How does discovery work on each platform?

This is the biggest difference, and it shapes what kind of creator and video you should book.

TikTok decides who sees a video mostly by what that viewer has watched before. Follower count barely matters. A new creator’s video can reach hundreds of thousands of people if the first few seconds hold attention.

Instagram Reels mixes both. Followers see a creator’s Reels first, and good ones get pushed to non-followers in the Reels feed and Explore. A creator’s existing relationship with their audience matters more here.

YouTube Shorts has its own feed, but it’s also tied into YouTube search and the creator’s channel. That means a Short answering a real question (“best budget running shoes,” “how to clean a cast iron pan”) can keep getting found long after it’s posted.

Matching the creator and format to how each platform finds videos takes experience across all three. INFLUENCE picks creators by where their content already performs, not just where they have followers.

Who’s watching each platform?

All three reach a lot of people, but the mix is different.

• YouTube is used by 84% of U.S. adults, the broadest reach across age groups, according to Pew. (Pew Research Center)

• Instagram is used by half of U.S. adults and 80% of 18- to 29-year-olds.

• TikTok is used by 37% of U.S. adults, with especially heavy daily use among people under 30.

And Shorts is enormous on its own. YouTube CEO Neal Mohan said in June 2025 that Shorts was averaging 200 billion daily views. (Search Engine Journal)

What that means for brands: if your customers are spread across ages, or skew older, YouTube Shorts deserves a place in the plan. If they’re under 30 and buy on impulse, TikTok usually leads. If they’re image-conscious buyers who follow creators they trust, Reels is hard to beat.

Picking platforms by your real customer, not by habit, is usually where the gains are. INFLUENCE helps you weigh TikTok, Reels and Shorts against who you’re actually trying to reach.

How much do creators cost on each platform?

Creator rates are broadly similar for similar views, but competition from other brands changes the price.

• Instagram has the most brand competition. Instagram led Collabstr’s 2025 bookings with 40% of campaigns.

• TikTok was 21% of campaigns on the same marketplace.

• YouTube was just 3%. (Collabstr)

Fewer brands booking Shorts creators means less competition for good ones, and sometimes better prices for the same views, especially from creators who make both long-form YouTube videos and Shorts.

To compare quotes across platforms, divide each price by the creator’s typical (median) views and multiply by 1,000. Our gaming CPM calculator does that math, and it works for any category.

Comparing quotes across three platforms by hand takes time. INFLUENCE prices every campaign on delivered views, so a view costs what you agreed whichever platform it’s on (see how).

What ad tools can you use with creator posts on each?

All three let you boost creator content, but the mechanics differ.

Whichever you use, agree on the duration and usage rights in writing before the post goes live, and keep the disclosure in place. More on running creator posts as ads in how to use creator videos as ads.

Ad permissions on three platforms mean three different processes. INFLUENCE agrees the permissions and usage terms for each platform as part of the creator deal.

Which should your brand use, and how do you run all three?

Start from your goal and customer, then test.

To run one idea across all three without tripling the work:

1. Brief one core idea with platform-specific notes (hook, length, look).

2. Ask creators who post on more than one platform for native edits of each, not watermarked reposts.

3. Post within the same week so the idea shows up everywhere at once.

4. Give Shorts a searchable title and description; it’s the one platform where words keep working.

5. Compare cost per result after four weeks, then move budget toward what worked.

Running one idea across three platforms with dozens of creators is a lot of moving parts. INFLUENCE manages creators, briefs and posting across TikTok, Reels and Shorts, with every creator and video approved by you first.

TikTok, Reels and YouTube Shorts aren’t interchangeable. TikTok is the discovery engine, Reels is the trust builder and Shorts is the long-tail workhorse with the broadest audience and the least brand competition. Match the platform to your goal and customer, brief one idea with native edits for each, line up ad permissions early and let a month of results decide the split. INFLUENCE runs campaigns across all three, priced on the views each one delivers.

Same idea, three native edits, and let each platform do its job.
