Influencer marketing on TikTok: a practical guide for brands

TikTok is no longer just for Gen Z. By 2026, it's a platform for research, product demonstration, and purchasing decisions, used by brands as diverse as food retailers, FMCG companies, health brands, and B2B businesses. If you haven't yet structured your influencer strategy on TikTok, you're falling behind the competition. This guide gives you the tools to close that gap.

Why TikTok has become essential for influencer marketing

TikTok now boasts 1.582 billion active users worldwide, including 27.8 million in France. It's the second most used platform for commercial collaborations in Europe, behind Instagram but ahead of YouTube. And unlike Instagram, its algorithm doesn't favor accounts with the most followers—it prioritizes content that captures attention, regardless of the size of the community.

This detail changes everything for brands. On TikTok, a creator with 15,000 followers can generate as many views as a profile with 500,000 if their content resonates. It's a rare opportunity: a playing field where quality and relevance take precedence over fame.

The figures confirm this trend. Micro-influencers have an average engagement rate of 8.2% on TikTok, compared to 5.3% for macro-influencers. And 33% of the platform's users have already purchased a product after discovering it in a video.

TikTok by sector: where does it work best?

According to the Reech 2026 study, TikTok performs particularly well in the following categories: luxury (81%), travel (77%), food (68%), family (64%), home decor/DIY (60%), tech (58%), and culture (57%). Beauty and fashion remain the traditional verticals, but the platform has diversified significantly. Consumer goods, healthcare, and even B2B brands are now finding their audience there.

Step 1 — Understand the platform's rules before you begin

The most common mistake brands make on TikTok is importing their Instagram strategy. These are two platforms with radically different codes. On TikTok, content that is too polished, too scripted, or too commercial is systematically penalized by the algorithm—and especially by users.

The 3 fundamental rules of TikTok

• Authenticity above all : 40% of users find brands that show their personality more relevant (TikTok What's Next Report). Imperfect but sincere content performs better than polished, artificially produced content.
• The first 3 seconds are crucial : they determine 71% of decisions to continue watching. If your hook is too slow, the user will swipe away before even seeing your message.
• Sound is strategic : 68% of users remember a brand better when it uses music in its videos. Choose trending sounds or create your own sonic identity.

Step 2 — Identify and select the right TikTok creators

On TikTok, the number of followers is even less relevant than on Instagram. A creator with 20,000 highly engaged followers in a specific niche (food, health, retail, family) will often generate better results than a generalist profile with 200,000 followers.

TikTok-specific selection criteria

• The completion rate : what proportion of viewers watch the video to the end? This is one of the strongest signals in the TikTok algorithm. A good TikTok creator maintains a high completion rate—ask them for their stats.
• Engagement rate : calculate (likes + comments + shares) / views × 100. A good threshold: 3 to 5% minimum. TikTok micro-influencers often reach 8 to 10%.
• Thematic consistency : does the creator regularly deal with topics close to your sector? An inconsistency between their usual universe and your brand will be perceived as artificial by their community.
• History of collaborations : does he multiply product placements every week? Overexposure to commercial advertising erodes audience trust and reduces the effectiveness of your campaign.

Where to find your TikTok creators

TikTok Creative Center is the official starting point—it gives you access to industry trends and top-performing creators. Specialized platforms (Kolsquare, Influence4You, Reech) offer advanced filters that include TikTok analytics. Organic search via niche hashtags also remains highly effective for discovering emerging profiles before they're targeted by your competitors.

Step 3 — Structure your TikTok campaign

A well-structured TikTok influencer campaign is based on three key decisions: the content format, the level of creative freedom given to the creator, and the duration of the collaboration.

Formats that will work in 2026

• The short testimonial video (15 to 30 seconds): the creator presents the product in its natural context, without a script. This is the most authentic format and the one that generates the best engagement rates.
• The before/after comparison : particularly effective for beauty, health, food, and DIY products. It demonstrates a concrete result in seconds.
• The answer to a question (Stitch format or standalone video): the creator answers a frequently asked question from their audience, naturally incorporating your brand. This format is highly ranked by the TikTok algorithm, which prioritizes useful content.
• Live shopping : TikTok Shop now allows users to buy directly from a live stream. Live sessions generate a 22% higher conversion rate compared to traditional product videos.
• The hashtag challenge : you create a branded hashtag and invite creators (and their communities) to produce their own version. Ideal for large-scale brand awareness campaigns.

Creative freedom vs. key messages: finding the right balance

On TikTok, the rule is clear: the more creative freedom you give the creator, the better the content will perform. Their community follows them for their tone, humor, and editing style—not for your message. Impose two or three non-negotiable key points (product mention, link in bio, mandatory hashtag), and let the creator do the rest.

Step 4 — Amplify content with TikTok Ads

A TikTok influencer campaign doesn't stop at organic posting. The content created by your influencers is a valuable resource that you can amplify with paid advertising to multiply its reach.

Two complementary approaches:

• Spark Ads : You directly boost the video published by the creator, from their account. The content retains its authentic feel (visible creator account, real comments), but benefits from targeted paid distribution. It's the most effective format for combining influencer credibility and paid performance.
• Search Ads : Since 2025, TikTok has allowed brands to appear in the platform's internal search results. If a user searches for "quick recipe," "skincare routine," or "B2B tool," your content can appear at the precise moment the search intent is expressed.

This organic + paid combination is the most profitable strategy on TikTok in 2026: you pay to create the content once, and you exploit it across multiple channels.

Step 5 — Measure the performance of your TikTok campaign

TikTok KPIs differ slightly from those of an Instagram campaign. Here are the metrics to track depending on your objective.

KPIs according to the objective

• Brand awareness : impressions, cumulative reach, new followers on your brand account, volume of campaign hashtag mentions
• Engagement : engagement rate (likes + comments + shares / views), completion rate, number of videos created in response (Stitch, Duet)
• Conversion : clicks tracked via UTM, promo codes used, TikTok Shop sales attributed, cost per acquisition

One point to note specific to TikTok: views alone are not a sufficient indicator. A video with 500,000 views, 0.5% engagement, and a 15% completion rate performs worse than a video with 50,000 views, 6% engagement, and a 45% completion rate. Always dig deeper into the secondary data.

Frequently Asked Questions about TikTok Influencer Marketing

What budget should be allocated for a TikTok influencer campaign?

The budget varies depending on the profile of the creators involved and the number of content items commissioned. In France, a collaboration with a TikTok micro-influencer (10,000 to 50,000 followers) generally costs between €100 and €500 per video. For a macro-influencer (100,000 to 500,000 followers), expect to pay between €1,000 and €5,000 depending on the theme and format. In addition to this creative budget, if you opt for amplification, you will need to allocate a separate budget for Spark Ads.

Does TikTok work for B2B brands or less "consumer-oriented" sectors?

Yes, provided you adapt the formats. B2B on TikTok operates on an educational and practical model: tutorials, demonstrations, answers to business questions, and behind-the-scenes glimpses of companies. Sectors like healthcare, DIY, professional food, and tech find highly engaged audiences on the platform. The key is to identify creators specializing in your niche rather than seeking maximum reach.

Is it better to work with a single macro-influencer or several micro-influencers on TikTok?

On TikTok in particular, a multi-micro strategy is generally more effective. The platform's algorithm favors authenticity and niche specialization—two qualities that micro-influencers embody better than major stars. Activating 5 to 10 targeted micro-influencers typically generates a better ROI than a single macro placement, with the same budget.
