Prioritise the app where your audience already is and where your videos fit: YouTube Shorts if you also make long videos or want search and steady ad revenue, Instagram Reels if you sell, collaborate or your audience already follows you there, TikTok if you want the most open discovery for a new account. If one vertical video suits all three, post it to all three, cleanly, each at its own hour.
- YouTube Shorts average over 200 billion daily views (June 2025).[1]
- Instagram has 3 billion monthly active users (Q3 2025) and reached 2 billion daily actives by mid-2026.[2][3]
- TikTok said in 2021 that more than 1 billion people use it every month; it has not published a newer global figure we could find.[4]
- Shorts creators keep 45% of their allocated revenue from the Shorts ad pool.[5]
- TikTok’s Creator Rewards Program pays for original videos over 1 minute long, from accounts with at least 10,000 followers and 100,000 views in 30 days.[6]
Reels vs TikTok vs Shorts, side by side
| Instagram Reels | TikTok | YouTube Shorts | |
|---|---|---|---|
| Scale (official) | 3B monthly Instagram users[2] | 1B+ monthly users (2021 figure)[4] | 200B+ daily views[1] |
| Longest video | 3 minutes[7] | Longer videos allowed; see platform specs | 3 minutes[8] |
| How it pays creators | No published revenue share like YouTube's; brand deals and Instagram's own programmes | Creator Rewards for originals over 1 minute[6] | 45% of allocated ad revenue[5] |
| Discovery for a new account | Small test audience first, then wider[9] | For You feed; follower count not a direct factor[10] | Shorts feed personalised to each viewer[11] |
| Best extra | Trial reels test with non-followers first | Duet and Stitch | Shorts lead into long videos and search |
Reach and audience
YouTube says Shorts average over 200 billion daily views.[1] Its last published monthly figure was over 2 billion logged-in Shorts viewers, from 2023.[12] Instagram passed 3 billion monthly users in 2025 and 2 billion daily users by mid-2026, and Reels are reshared over 4.5 billion times a day.[2][3][13] TikTok last published a global number in 2021: more than 1 billion monthly users.[4]
The useful question is not which is biggest, but where your viewers already watch. Check your own insights, and ask your audience.
How each one finds viewers
- Instagram Reels tests a new reel on a small audience and widens it if it performs.[9] Shares, full watches and likes are the strongest signals.[14]Watermarked or reposted clips are recommended less.[9]
- TikTok ranks on interactions and video information, and says follower count and past hits are not direct factors.[10] That is why new accounts can break out there.
- YouTube Shorts personalises the feed from what each viewer watches, searches and likes.[11] Shorts live next to long videos, so a Short can send viewers to your longer work.
Getting paid
- YouTube Shorts: monetising creators keep 45% of their allocated Shorts revenue. YouTube has announced stricter Creator Pool eligibility from 1 February 2027 (10 million qualified Shorts views in 90 days).[5]
- TikTok: the Creator Rewards Program pays for original videos over one minute, from creators 18+ with 10,000 followers and 100,000 views in the last 30 days.[6]
- Instagram: publishes no standing ad-revenue share for Reels like YouTube’s. Money comes mostly from brand deals, subscriptions and Instagram’s changing creator programmes.
Which to prioritise: a quick decision
- You also make long videos, or want viewers who find you through search for years? YouTube Shorts.
- Your audience already follows you on Instagram, or you sell, run a shop or work with brands? Instagram Reels.
- You are starting from zero and want the most open discovery? TikTok.
- None of the above is clear? Post the same clean video to all three for a month and compare views after 24 hours.
Main platform means where you read comments, test ideas and reply first. It does not mean the only platform.
Or post to all three
The same vertical video fits all three. What changes is the caption, the sound you add in-app and the hour each audience is awake. Done properly, one edit becomes three native posts: see how to cross-post without watermarks. Octoque does the scheduling part: one upload, a caption tab per platform, each going out at its own golden hour.
Questions people ask
Is TikTok or Reels better for growth?
Do YouTube Shorts help a long-form channel?
They share one channel, so Shorts viewers can find your long videos. YouTube’s ad share for Shorts is 45%.[5]
Can I post the same video to all three?
Yes, if it is your own clean export with no other app’s watermark. All three say watermarked or reused clips are recommended less or not paid.
How long should my short videos be?
When should I post on each?
At each platform’s own best hour for your audience. See best time to post.
Kumar Gaurav builds Octoque. Creators should spend their time making things, not watching clocks. So you make the video, and Octoque finds the moment: one upload, every platform, each at its golden hour. These guides follow the same idea. Real channels, real numbers, nothing you don’t need.
