"Which platform should we use?" comes right after "how much should we spend?" in most of our first calls with app and tech teams. There's no single right answer, but there is a right answer for a given product, audience and goal.
This guide compares TikTok, Instagram and YouTube for creator campaigns aimed at app growth, and covers where LinkedIn and X fit for B2B products. It draws on how the platforms describe their own recommendation systems and on what we've seen across Dime campaigns.
How do the platforms decide who sees a creator's post?
It helps to understand how each platform distributes content, because that shapes what kind of campaign works there.
TikTok recommends videos in the For You feed based on how people interact with content, such as what they watch, like, share and comment on, along with video information like captions and sounds (TikTok newsroom). Following a creator isn't required to see their videos. That gives a new post a real chance to reach people outside the creator's existing audience.
Instagram uses different ranking systems for Feed, Stories, Explore and Reels, each built around how people use that part of the app (Instagram). Feed and Stories lean on accounts you follow. Explore and Reels are where most discovery of new accounts happens.
YouTube recommends videos on the homepage and in the Up Next panel based on viewing behavior, subscriptions and feedback, and ranks search results on relevance, engagement and quality (YouTube). Search is a big part of how people find YouTube videos, which is why a good tutorial can keep getting views long after it's posted.
When is TikTok the best choice for app growth?
TikTok is often the best place to start when you need reach and fast learning.
Strengths
- New posts can reach people who don't follow the creator, so even mid-sized creators can break out.
- Short videos are cheap to make, so you can test many concepts quickly.
- Trends and formats spread fast, which suits products with a fun or surprising moment, like an AI tool that does something unexpected in seconds.
Weak spots
- Short videos leave little room for complex products.
- Attention moves on quickly, so you need a steady flow of posts.
- Links are harder to put in front of viewers than on some other platforms, so tracking often relies on promo codes, link-in-bio pages and post-install surveys.
Example: our Gauth campaign for ByteDance was a nationwide campus takeover with student creators on the For You Page, with 80+ influencers across 50+ universities and 10M+ views. Students talking to students about homework help is exactly the kind of peer content TikTok spreads well.
When is Instagram the best choice?
Instagram works well when your users belong to a visible community, or when the product is visual.
Strengths
- Strong niche communities with their own creators, hashtags and culture
- Reels for discovery, Stories for repeat exposure and links, and carousels for step-by-step explainers
- Creators who mix product moments into lifestyle content in a natural way
Weak spots
- Reach on Feed and Stories leans on existing followers, so creator selection matters a lot
- Saturated categories can make sponsored posts blend together
Example: for ElevenLabs, we worked with Bookstagram and reading-community creators to drive adoption of ElevenReader and the ElevenLabs Student Pack. 200+ influencers and 70M+ views. Readers who share what they're reading are a natural audience for a tool that reads books aloud.
When is YouTube the best choice?
YouTube is strongest when people need to see the product properly before they try it.
Strengths
- Room for real demos, walkthroughs and honest reviews
- Videos keep getting found through YouTube search and Google, long after posting
- Viewers who watch a long video are often close to a decision
- Shorts give you a short-form option on the same platform
Weak spots
- Longer videos take more time to produce, so lead times are longer
- A dedicated video usually costs more than a short post
- Fewer posts means fewer chances to test angles
YouTube is a natural fit for developer tools, productivity software and other products where "how do I actually use this?" is the main question. It also matters for AI search. Video titles, descriptions and transcripts are public text that can be found and cited. We cover that in how creator content feeds AI search visibility.
Where do LinkedIn and X fit for tech products?
For B2B products, the buyers are often on LinkedIn and X more than on TikTok or Instagram. That's where engineers, founders and operators follow people in their field.
Our B2B work activates industry creators and operators to talk about a product on LinkedIn and X, building awareness, credibility and trust with the people who make buying decisions. For developer tools, the creators who matter are often practitioners. CodeRabbit's campaign used senior and lead engineers introducing the product to the developer audiences who follow them, with 100+ influencers and 50M+ reach.
How do the platforms compare side by side?
| TikTok | YouTube | LinkedIn and X | ||
|---|---|---|---|---|
| Best for | Reach and fast testing | Communities and visual products | Demos and tutorials | B2B awareness and trust |
| Discovery | For You feed, beyond followers | Reels and Explore | Search, Home and Up Next | Feed and reposts |
| Content life | Short | Short to medium | Long, through search | Short to medium |
| Testing speed | Fast | Medium | Slower | Medium |
Should you use more than one platform?
Often, yes. A common pattern is to test concepts on TikTok or Reels, use YouTube for deeper demos of the winning angle, and run LinkedIn creators for the B2B side of the same product. Suno's always-on program, with musicians, comedians, couples and educators showing off text-to-song across 1000+ influencers and 100M+ views, worked because the product had a different hook for each audience.
Start with the platform where your users already spend time and where your product is easiest to show. Add the next one once you know which concepts work.
