TikTok vs Instagram Reels for business: which should a small business use?

Both apps reward short, useful, watchable videos. The difference is what happens after someone watches.

• Instagram Reels sits next to your grid, Stories and DMs. Viewers who like a Reel can check your profile, message you and come back. That makes it strong for local businesses and repeat customers.
• TikTok is built to push videos to people who have never heard of you. It is strong for awareness, testing ideas and reaching a younger audience.

If you only have time for one, pick the app your customers already use most, then add the second once you have a steady rhythm.

Pew Research Center surveyed 5,022 US adults between February and June 2025. It found that 50% use Instagram and 37% use TikTok, while YouTube (84%) and Facebook (71%) remain the largest.

Age makes a big difference. Pew reported that 80% of adults aged 18 to 29 use Instagram, compared with 19% of those 65 and older. For TikTok, roughly half of 18 to 29 year olds use it every day, against 5% of adults 65 and older.

So if your best customers are over 45, Instagram and Facebook usually reach more of them. If they are under 30, TikTok deserves a serious look.

Socialinsider tracks organic posts from brand accounts with 1,000 to 1 million followers. Its 2026 benchmarks put average engagement by followers at 2.50% on TikTok and 0.45% on Instagram, both slightly down on the year before.

It also reported more average views per post on TikTok (6,496) than on Instagram (3,403) in 2025, though each platform counts views differently.

What that means for a small business

TikTok gives a new account a better chance of being seen by strangers. Instagram engagement is lower on average, but the people who engage are more likely to be followers, customers and locals you can talk to directly.

Cafes, salons, clinics, gyms, trades and restaurants usually get more from Instagram, because the goal is not millions of views. It is the right few hundred people nearby who will visit, book or call.

TikTok can still work locally, especially with younger customers, but views are more likely to come from people far away who will never buy. For local search, also keep your Google Business Profile active. Our local SEO checklist covers the basics.

For physical products, short demos, behind-the-scenes clips and unboxings work on both apps. Test the same videos on both for a month and keep the one that brings sales, not just views.

For B2B, short video is useful for showing expertise and personality, but your buyers are more likely to act on LinkedIn. Our guide to LinkedIn ads for small business covers paid options there.

Reposting your own video is fine. What to avoid is downloading a TikTok, with its watermark, and uploading that to Instagram.

Instagram said in April 2024 that it would favour original content, replace reposted clips in recommendations with the original and stop recommending accounts that repost others' content 10 or more times in 30 days. That rule targets other people's content, but a clean, native upload is still the safest route for your own.

A simple workflow

1. Film vertical, 9:16, with the key action in the middle.
2. Edit in one tool and export without any app watermark.
3. Upload natively to each app and add on-screen text there.
4. Write a caption for each audience. TikTok captions can be more playful, Instagram ones more direct.

Instagram raised the Reels limit from 90 seconds to 3 minutes in January 2025, announced by Instagram's head, Adam Mosseri. TikTok also allows longer uploads.

Length is not the goal, though. Most small business videos land best when they make one point quickly: a tip, a demo, a before and after or a customer story. Our short-form video guide covers ideas and formats, and our guide on how often to post covers the rhythm.

Filming and editing two or three short videos a week can easily take several hours. That is fine if you enjoy it, but it adds up for a busy owner.

Many businesses start in-house, then bring in a freelancer or agency for planning, editing or full production once they know what works. Our guide to social media marketing costs breaks down typical budgets, and our social and short-form video service covers planning, filming and editing.
