What are the best influencer marketing campaign examples and case studies?

Last updated · by Hüseyin Kaplan

The best influencer marketing examples pair one simple mechanic with creators who already fit the audience. Think e.l.f.'s #eyeslipsface TikTok challenge, Chipotle's #GuacDance, Gymshark66's ambassador-by-challenge, and UK and Irish beauty brands boosting creator videos as Spark Ads. Below are sourced case studies with the mechanic, the result and the lesson, then the patterns the winners share.

Which influencer campaigns are worth copying?

The campaigns worth copying are the ones that published a result you can check. Here that means e.l.f.'s TikTok challenge and its UK concealer launch, Chipotle's #GuacDance, Gymshark66, and two beauty brands from the island of Ireland that turned creator videos into ads. Each card gives the brand, the mechanic, the result and the lesson.

Every figure comes from the brand's own press release, its Shorty Awards entry or TikTok's published case study. Treat them as results the brands reported, not audited ones. For restaurants, Chipotle's #GuacDance is still the case to study, because it reported a sales proxy (guac sides served) and not just views.

For fashion and apparel, Gymshark is the clearest UK example. It recruits athletes through its Gymshark66 challenge and sells collections built around creator-athletes such as Whitney Simmons.

e.l.f. Cosmetics: #eyeslipsface (TikTok challenge, beauty)

Mechanic: e.l.f. tested paid TikTok alongside Snapchat and Pinterest. When TikTok beat its benchmarks, the brand launched a hashtag challenge set to an original song that spells out eyes, lips, face. Result: the challenge passed roughly 4.4 billion views, and the wider campaign brought 31 million video views and 548,000 new website users in 90 days. Lesson: give creators a sound and a move, not a script.

e.l.f. Cosmetics: Soft Glam Concealer UK launch (creator content plus Spark Ads)

Mechanic: TikTok's Branded Buzz paid creators to post about the concealer. The best videos were then boosted as Spark Ads, alongside TopView, prime-time and category search placements. Result: 143 million impressions, 13.3 million people reached, a 10.6% lift in awareness and an 88% incremental lift in view-content conversions. The product sold out across the UK before the campaign ended. Lesson: put paid reach behind creator posts that are already working.

Chipotle: #GuacDance (restaurant, TikTok challenge)

Mechanic: for National Avocado Day, Chipotle asked fans to dance to Dr. Jean's viral guacamole song and gave free guac on digital entrée orders. Result: over 250,000 video submissions, nearly 430 million video starts in six days, and the chain's biggest guac day ever, with over 802,000 sides served. Lesson: tie a challenge to a date and an offer people can act on that day.

Gymshark: Gymshark66 (UK fitness apparel, ambassador recruitment)

Mechanic: entrants post a pledge tagged #Gymshark66 between 28 December and 4 January, share progress at least weekly, then post a final update by 8 March. The winner gets official athlete status, a year's supply of kit, trips to LIFT events, a photoshoot and a year's gym membership. Lesson: recruit ambassadors from the people already posting about you.

KASH Beauty: launch content run as Spark Ads (Irish creator-founded brand)

Mechanic: founder Keilidh Cashell and makeup artists Laura Johnson and Orla Fenton posted first impressions, demos and trend videos ahead of two skin-product launches. KASH ran these as Spark Ads to Irish women aged 18-40 over one summer. Result: over 7 million impressions, more than 39,000 clicks and a 2.22 return on ad spend. Lesson: content that teaches people how to use a product sells launches.

Bellamianta: Black Friday on TikTok Shop (Northern Irish tanning and skincare)

Mechanic: from 1 November to 5 December, the County Tyrone brand mixed creator videos with in-house trend content. It ran them as Spark Ads and Video Shopping Ads pointing to its TikTok Shop, and found creators through organic search, PR lists and its TikTok account managers. Result: ROAS rose more than 14x in November, with a reach of 458,670. Lesson: send creator traffic straight to a checkout.

How do you build a brand ambassador program (with examples)

Which campaign format should you copy?

Choose the format by the job you need done. Seeding builds early word of mouth, creator ads drive paid performance, a challenge buys reach, an ambassador program gives you always-on content, and affiliate links or codes track sales. Most winners in this guide combined two formats: creator content first, then paid amplification.

Codes and links are the usual way to track results. According to Influencer Marketing Hub's latest benchmark report, promo or discount codes are the most used measurement tool (45.9% of respondents), followed by affiliate links (26.0%). If you want the ambassador model without building the tooling yourself, #Collabz runs always-on programs, each with its own application page and a discount code plus commission.

Product seeding

Send product with no obligation to post, then see who talks about it. None of the campaigns here published a result from seeding alone. Bellamianta did, though, find TikTok creators partly through its PR lists, so seeding fed a paid campaign. Lesson: use seeding to find the creators worth paying, then brief them properly.

UGC and creator ads

Brief creators to make native videos, then run the best ones as Spark Ads or partnership ads. KASH Beauty, Bellamianta and e.l.f.'s UK launch all took this route. Lesson: a post that would fade organically becomes an ad you can scale, provided the contract covers paid usage and how long it lasts.

Branded challenge

Give people a hashtag, a sound and one simple action. e.l.f. used an original song, Chipotle used a song that had already gone viral, and Chipotle added an offer valid on the day. Lesson: a challenge needs reach to get started, from paid placements or well-known creators, and works best for brands with a broad, young audience.

Ambassador program

Recruit a standing group of creators or customers who post regularly in return for product, perks or commission. Gymshark66 turns a yearly challenge into athlete selection. Lesson: ambassador programs get stronger over time, because the best posts come from people with real progress to show.

Affiliate and discount codes

Pay creators per sale through a tracked link, a code or a TikTok Shop affiliate listing. Bellamianta used Video Shopping Ads to push creator traffic into its TikTok Shop. Lesson: commission-only deals suit creators who already buy from you. Add a flat fee when you need guaranteed content on a deadline.

What is influencer gifting / product seeding and how do you run a gifting campaign

Which kinds of influencer appear in the winning campaigns?

The winners mix creator types instead of betting on one celebrity. Across these cases you find creator-founders, expert creators, ordinary customers and paid groups of niche creators.

Budgets are moving the same way. Influencer Marketing Hub's latest benchmark report found 52.83% of marketers plan to expand their use of micro-creators, while plans for macro creators split almost evenly between expanding (20.59%) and cutting back (20.58%). For a DTC brand, the practical version is a bench of smaller creators who know the category, plus one or two bigger names for launches.

Creator-founders

Irish makeup artist and influencer Keilidh Cashell founded KASH Beauty and fronts its campaigns. A founder-creator brings trust and speed, but the brand then relies on one face. Pairing the founder with outside creators, as KASH did, widens reach without losing that trust.

Expert creators

KASH's launches added makeup artists Laura Johnson and Orla Fenton for first impressions and demos. Expert creators show people how to use a product. That matters most for skincare, supplements and complex formulas, where buyers need a reason to switch from what they already use.

Customers as creators

Gymshark66 asks ordinary people in its community to post a pledge, weekly progress and a final result. The brand gets a steady flow of genuine progress posts, and it picks its next athlete from the entrants who kept showing up for all 66 days.

Paid creator crowds

TikTok's Branded Buzz pays many creators to post about one campaign at the same time. e.l.f. used it for its UK concealer launch and then boosted the strongest videos. It gets you volume without one creator carrying the whole result.

Where creator budgets are heading

  • 72.2% of marketers answering expect their influencer budget to rise by 50% or more.
  • 52.8% plan to expand their use of micro-creators; only 7.55% plan to cut it.
  • 45.9% use promo or discount codes to measure influencer results, the most common method.
  • 66.2% of social commerce adopters' platform selections go to TikTok Shop, far ahead of Instagram Checkout.

How do you run an influencer campaign like these?

Follow the order the winners used: one clear job, creators who already fit, a mechanic simple enough to copy, paid spend behind what works, and a way to count sales. The full planning process is in our strategy guide. The steps below are what these campaigns have in common.

Pick one job

Choose awareness, launch sales or content volume, not all three. e.l.f.'s UK concealer campaign tracked awareness and ad recall as well as conversions, but every placement served one product launch. One job tells you which format, which creators and which metric to use.

Brief a hook, not a script

Give creators the key facts about the product, the one action you want viewers to take, and freedom over how they deliver it. KASH Beauty's best videos used quick transitions and grabbed attention in the first few seconds. That came from the creators' own style, not a brand script.

Put spend behind winners

Wait for organic signals, then boost the top posts as Spark Ads or partnership ads. Agree paid usage rights and their duration in the contract before anything goes live. That way you can scale a winning post the day it appears instead of renegotiating.

Disclose every time

The ASA and CMA influencers' guide sets out when paid, gifted and affiliate content must be disclosed in the UK. As a working rule, label it 'Ad' in the UK and '#ad' in the US. That still applies when the only thing the creator received was free product.

Count sales, not just views

Give each creator a code or tracked link, and fix your reporting window before launch. Chipotle reported guac sides served and Bellamianta reported ROAS. That is why their case studies are more useful than ones that only report view counts.

How do you build an influencer marketing strategy (step by step)

How should you read an influencer case study?

Read every case study as marketing first. Check who published it, what was counted, how long the campaign ran, and whether the headline number is views or sales. Most public cases come from the platform or agency that ran the work, and TikTok's own case studies carry a note that past performance does not guarantee future results.

Look for a business result (a sell-out, ROAS or orders) and a clear time window. Almost no case study discloses total cost, so return on ad spend is usually the best guide you have to efficiency.

Who published it

A brand press release, an award entry or a platform case study: all three have a reason to show the best numbers. Prefer cases where the brand itself reports a business result in its own words, as Chipotle did with its record guac day.

What was counted

Views, impressions and video starts show reach. Sales proxies such as units served, sell-outs or return on ad spend show whether that reach paid off. The most useful cases report both, as e.l.f.'s UK launch did with awareness lift alongside a sell-out.

How long it ran

Check the dates. Chipotle's challenge ran six days, Gymshark66 runs 66, and KASH's campaign ran over one summer. Short windows flatter view counts. Longer windows show whether sales held up after launch week.

Whether it fits your size

Ask whether the mechanic matches your budget. A branded challenge with premium placements costs more than most DTC brands can spend. A Spark Ads campaign built on three creators, like KASH's, is within reach of a small team.

What patterns repeat across winning campaigns?

Five things repeat across the winners: one action anyone can copy, creators before ads, a fixed moment, a short path to checkout, and a community that supplies the next wave of creators. None of them relied on a single post from a single big name.

Checkout is moving onto the platforms as well. In Influencer Marketing Hub's latest benchmark report, TikTok Shop made up 66.17% of platform selections among brands already selling through social commerce.

One action anyone can copy

A dance, a pledge, a first impression. If viewers cannot describe the idea in one sentence, they will not join in. e.l.f.'s challenge built the brand name into the song, so every entry repeated the message without anyone having to explain it.

Creators first, ads second

e.l.f. UK, KASH Beauty and Bellamianta all started with native creator videos, then paid to show the best ones to more people. The ad budget amplified proof that already existed rather than trying to create it from scratch.

A fixed moment

National Avocado Day, New Year resolutions, Black Friday, a product launch. A date gives viewers a reason to act now and gives creators a deadline. It also gives you clean before-and-after windows to measure against.

A short path to buy

Free guac on digital orders, a TikTok Shop listing, a launch page. Every winner pointed attention at one action. That is why they could report sales instead of reach alone.

Community as the creator pipeline

Gymshark chooses athletes from Gymshark66 entrants, and Bellamianta found creators already working in its niche. Your best future ambassadors are often already posting about you, so set up a way to find and reward them.

Frequently asked questions

What are good B2B influencer marketing examples?

B2B examples are rarer but they do exist at the top end. Salesforce built a Super Bowl teaser around MrBeast pitching its marketing team, using the creator's format and audience instead of a standard ad. Smaller B2B brands usually work with niche experts on LinkedIn or YouTube, which our B2B influencer marketing guide covers.

What makes an influencer marketing campaign successful?

A successful campaign has one clear goal, creators who already fit the audience, a simple action people can copy, and a way to count sales. In the examples in this guide, the strongest cases reported business results such as sell-outs, ROAS or orders, not only views.

What are good TikTok influencer marketing examples?

The best-documented TikTok cases are e.l.f.'s #eyeslipsface challenge, Chipotle's #GuacDance and e.l.f.'s UK Soft Glam Concealer launch. For smaller brands, KASH Beauty and Bellamianta show how a few creators plus Spark Ads can drive sales you can measure.

Who are some examples of social media influencers that brands work with?

In these case studies they range from creator-founders such as Keilidh Cashell of KASH Beauty, to makeup artists Laura Johnson and Orla Fenton, to creator-athletes such as Whitney Simmons at Gymshark. Many brands also turn customers into creators, as Gymshark does through Gymshark66.

What are good micro-influencer marketing examples?

Gymshark66 and Bellamianta are the closest examples here, because both rely on people already active in their niche rather than celebrities. Gymshark chooses athletes from challenge entrants. Bellamianta found creators through organic search and PR lists before boosting their videos with ads.

How long should an influencer campaign run?

It depends on the mechanic. Chipotle's #GuacDance ran for six days, Bellamianta's Black Friday push ran about five weeks, and Gymshark66 runs for 66 days. Fix the window before launch so you can compare results fairly.

Do gifted influencer posts need an ad label?

Yes. In the UK, label a gifted post that promotes the brand 'Ad'. In the US, the FTC's Disclosures 101 guidance treats free or discounted products as a material connection that must be disclosed, usually with '#ad'.
