The days when influencer marketers were slinging new campaigns on a relatively unsaturated Instagram are long gone. Today, influencer collaborations have swooped in on not just social media platforms like TikTok, YouTube, LinkedIn, X, and Snapchat, but also in newsletters, podcasts, and private communities.
Our survey found that Instagram, TikTok, and YouTube take the lead as “the most successful social media platforms for influencer marketing programs.” But are certain social networks better for some industries than others? Which platform should you begin with? And once you branch out, how should your strategy differ on additional platforms?
I asked these questions (and then some!) to experts who have marketed on these three core platforms. Here’s what they had to say.
But first, let’s compare the strengths and weaknesses of each platform:
Instagram vs. TikTok vs. YouTube Comparison Table
Which social media platform should kickstart your influencer marketing efforts?
The TL;DR: Start with your overall goals for influencer marketing → evaluate which content formats would best achieve them → proceed with the formats within your budget. Don’t be afraid to combine similar content formats across different social media platforms.
Tamara Torrecillas Gutiérrez, Influencer Marketing Manager at DIALECT, suggests thinking in terms of content formats instead of social media networks. She explains with an example:
As a fashion brand, I could be on all three platforms, but I would modify the type of content. For Reels: 7 days, 7 looks. For Instagram Stories: Unboxing and reviews. For YouTube: Tutorials on how to dress for an occasion. For TikTok and YouTube Shorts: Same concept as Reels.
So, instead of considering whether certain social channels work better in your industry, align the various content formats these networks offer with your goals. Andreea Moise, influencer marketing consultant and founder at HypeMaven, says picking the right content format is also dependent on your sales cycle and customer journey:
If the cycle is short, you can get away with producing mainly short-form content or sticking to just one high-volume platform. But if the cycle is long, I’d always go for a mix of YouTube, too (30–50%).
She explains why:
Long sales cycles usually involve more research and consideration (e.g., high-ticket items, annual purchases, large volume, etc.), and long-form content plays a big role in buying decisions.
In light of that, here’s a quick summary of Instagram, YouTube, and TikTok's various content formats and what those formats are best for.
Marit Tiesema, Sr KOL & Ambassador Specialist at Loop Earplugs, explains with an example of combining YouTube long-form videos with Instagram Stories to generate sales:
Most industries could benefit from YouTube, as products can be integrated naturally into influencers’ daily lives. Combine this with a few Instagram Story frames to showcase additional moments of use and include links to purchase to create a compelling, well-rounded storyline.
She continues:
Instagram and TikTok tend to perform better for industries that rely on aesthetics, trend-driven content, and impulse purchases, while YouTube does best in industries that require in-depth explanations and long-form storytelling.
Yes, certain industries and campaigns are naturally better suited to some platforms than others. But that’s less of a platform choice and more of a content choice: once you have identified your content format, then consider which networks offer that format and how they differ. For example:
- Gifting campaigns generally perform better on Instagram and TikTok because these platforms have more content formats that promote brand awareness.
- Explainer videos of tech products are best suited to YouTube because of its long-form video content format.
Michael Todner, Influencer Marketing Manager at Gear4music, agrees:
It ultimately comes down to what you are trying to achieve. I wouldn't be going for Instagram if there’s a heavy focus on conversions in a campaign – I would think about YouTube instead. But if I'm looking to get a new product in front of as many eyes as possible, I would go for Instagram or TikTok over YouTube.
According to our survey, Instagram Reels is the top contender for sales via influencer marketing, followed by Instagram Stories and TikTok videos.
Your ICP research will also provide a general direction for where to put your influencer marketing efforts. Where are your customers most active? Which platforms influence their purchases the most? Andreea elaborates:
Find the place where people talk about their problems and pains the most. Look for places where they have created a community around finding solutions and recommendations, and look at what they’re telling your direct competitors on social media.
Lastly, choosing social media platforms also depends on your budget. Certain content formats – like Instagram Stories – are significantly more cost-effective than others – like dedicated YouTube videos. The more “polishing” and production required, the higher the cost. Marit agrees:
TikTok and Instagram allow for lower-cost content creation, with TikTok having the highest virality potential, while YouTube typically requires higher production costs but provides lasting content value.
Differences in influencer pricing for video content on Instagram, TikTok, and YouTube
Influencer pricing doesn’t just depend on the social media platform; it also depends on the content format you’re choosing, your industry, and the size of the influencer’s audience.
For the scope of this article, we’re going to stick to comparing video content. To begin with, below are some broad benchmarks for the cost of TikTok videos and Instagram Reels, segmented by follower count.
⚠️ Disclaimer: the above are ballpark prices based on creators in North America. Influencer rates may differ based on region, niches, usage rights, location, and exclusivity terms. Use the above numbers as a jumping off point.
What about YouTube Shorts? It’s still in its infancy as a content format, so Shorts is best used as an add-on, either by repurposing a long-form YouTube video or by cross-posting Instagram Reels and TikTok videos (with light edits).
For Instagram Stories, the prices depend on all the above factors and the number of frames. Here are some ballpark ranges we’re seeing:
For YouTube, influencer rates vary depending on whether you want a dedicated video or an integration. While a dedicated video is its own separate beast, we have a few ballpark ranges in the US market just for video integrations:
Again, the rates differ based on your market, industry, and agreements in your influencer contract.
Instead of asking influencers to deliver just one piece of content, ask them to bundle multiple types of content together. This is an excellent negotiation tactic to drive the price-per-deliverable down while also getting more influencer content. For example, you could ask an influencer to share a dedicated YouTube video and repurpose parts of it for TikTok, Instagram Reels, and YouTube Shorts.

Differences in influencer briefing for Instagram, TikTok, and YouTube
There is of course nuance for each platform, but let’s first look at some elements that should be present in every influencer brief, regardless of platform or content format:
- Campaign goals
- Brand details
- Product information
- FTC compliance guidelines
- Content inspiration
- Key talking points
- Dos and don’ts and/or general best practices
- Timelines
- Call-to-action
Here’s a summary of additional items you should include in specific briefs – differentiated by social media platform and content format. I’ve grouped Instagram Reels, TikTok videos, and YouTube Shorts together, as their briefs are similar and will contain a lot of overlap.
Influencer briefs also need to be tailored depending on the following factors:
- Whether the influencer is a new partner: new influencer partners need more guidance than those partners who have been with you for a while and are already familiar with your product. It’s also best to change your briefs depending on how many times a creator’s audience has seen your product in their feed. If you’re working with a new influencer, ask them to introduce the brand and the product slowly to build credibility first. Your brief can direct that partner to then create follow-up posts. .
- Whether you’re briefing for a specific or always-on campaign: for always-on campaigns, ask the influencer for their content schedule and see where your brand fits in organically. Specific campaigns, on the other hand, might need a more detailed briefing with a pre-existing concept in mind.
- Whether your product is complex: complex products (like musical instruments, tech products, etc.) might need more instructions and product education than more straightforward products (like clothing, phone cases, etc.).
Does the content approval process also differ across content formats? Yes. Dedicated YouTube videos that take a long time to shoot need content approvals at various stages (outline, script, etc.), whereas Instagram Stories might not need such a thorough content approval process. Here’s a useful chart to help you navigate giving creative freedom to influencers:

When should you add a new social media platform to your influencer marketing strategy?
Adding a new social media platform to your strategy depends on your risk appetite, experimentation budget, and campaign requirements. Marit suggests being ahead of the game – so don’t wait until you’ve exhausted a platform to experiment with another one:
When testing a new platform, start with a small, targeted group of influencers who share a similar audience and market. Launch within a short, controlled timeframe to collect reliable data. Approach it like a researcher – test a hypothesis, measure engagement, and iterate quickly based on insights.
Before expanding to another platform, always check that your target audience is present there and that the supported content formats make sense for your marketing strategy.
Once you have expanded to multiple platforms, keep testing different content formats so you don’t get burned by massive platform changes (like the potential TikTok ban in the US).
Would it be safer to begin with creators you’ve already partnered with on other platforms? For instance, if you already have a trusted influencer partner on Instagram and they also have a decent TikTok following, should you begin your TikTok influencer marketing through them? Andreea says that’s where she’d start:
Good concepts can work across platforms – I’d ask my previous partners to just crosspost old content with my brand on the new platform to get things started (if they haven’t already).
While working with the same creators is a safe bet, remember that there might be some audience overlap in this tactic. Michael agrees:
If you want a safer approach, partner with creators that you’re already working with. But bear in mind audience overlap. A creator’s audience likely consumes content from that influencer on more than one platform. So, you run the risk of not reaching a lot of new people.
It’s worth noting that multiple touchpoints are usually required before someone decides to purchase via influencer marketing. So partnering with the same creators on multiple platforms can work in your favor, even if they have some audience overlap. Marit adds:
Repetition isn’t a bad thing, but it’s important to weigh it against CPM and ROAS. If you’re reinforcing a message that’s already been shared multiple times, do it through an Instagram Story, which costs a fraction of what a YouTube video would.
If you’re looking to start fresh with a new audience on a new platform, Andreea recommends three ways to find new influencers:
- Checking if any new creators are following you on the new platform
- Starting with niche creators to establish a foothold and expand gradually
- Approaching influencers who are interacting with your competitors’ content on the new channel
Suppose you’re looking to layer another social media platform onto a pre-existing strategy of YouTube partnerships. In that case, a better approach might be to point people from the new platform to your YouTube videos. Michael explains with an example:
We’ll have YouTube as the main platform, and ‘supporting’ socials across the other platforms that funnel people towards the main piece of content. That can be a YouTube Short that redirects to the long form video or an unboxing Instagram Reel that has a CTA of, ‘check out the full thing on YouTube.
If you’re vetting new influencers for a social media platform, Marit suggests beginning with:
- Reliable creators: choose someone who has a reliable view range and has consistently performed well
- Micro influencers: don’t spend a massive amount of money when you’re still learning the ropes
- Trackable approaches: use UTM links or discount codes to measure success
- Community builders: choose influencers who engage with their audience
Marit also suggests asking creator partners to brainstorm content ideas for your new social media platform. This will not only help you learn the new platform faster, but also increase the strength of your influencer relationship:
If you're new to a platform, collaborate with the influencer on creative ideas. They know their audience best and will appreciate the partnership.
In addition to relying on your influencer partners for creative input, you’ll also want to add time-saving tools to your arsenal as you expand your marketing efforts across multiple platforms…
