TikTok Influencer Marketing Strategies for 2025

TikTok isn’t just for dance challenges anymore – it’s become a serious eCommerce engine. With around 2 billion users worldwide, TikTok now drives product discoveries and impulse buys at an astonishing rate. In fact, roughly 37% of U.S. TikTok users (55 million people) made a purchase through the app in 2023, and that number is only growing. For online sellers, this means one thing: TikTok influencer marketing needs to be a key part of your 2025 strategy. In this blog post, we’ll explore the top TikTok influencer marketing strategies – from leveraging micro-influencers and UGC to riding trending hashtags – all tailored for eCommerce brands. The tone is casual but informative, so grab a coffee and let’s dive into how you can boost your sales and brand presence on TikTok this year.

Micro-Influencer Partnerships: Authentic Reach on a Budget

You don’t need Charli D’Amelio or the latest TikTok superstar to drive sales. In 2025, micro-influencer partnerships are proving that small can be mighty. Micro-influencers are typically creators with niche followings (say 1,000 to 50,000 followers) who are deeply trusted by their audience. For eCommerce brands, partnering with micro-influencers offers an authentic, cost-effective way to reach consumers.

Why focus on micro-influencers? First off, influencers are how TikTok users discover products – a whopping 78% of TikTok shoppers say they find new items through influencer content. But importantly, micro-influencers often deliver better bang for your buck. Top TikTok stars with millions of followers can charge upwards of $1,000 (or much more) for a single post, which can burn through a small brand’s budget fast. Micro-influencers, on the other hand, are far more affordable – many will collaborate in exchange for free product or a modest fee. Despite the lower cost, this doesn’t mean lower returns – quite the opposite. Micro-creators tend to have highly engaged communities that trust them, leading to higher conversion rates per viewer. Their recommendations feel more personal and authentic than a big celebrity endorsement.

Consider this scenario: you send your handmade jewelry to 20 micro-influencers who each have 5,000 followers in the fashion/jewelry niche. Each of them posts a TikTok showing how they style your pieces. Those videos might get, say, 2,000 views each – that’s 40,000 impressions of genuine content featuring your product, targeted at people who love handmade jewelry. The viewers seeing those posts are likely the exact customers you want, and they’re hearing about your brand from someone they trust. Even if each micro-influencer’s reach is small, collectively they make a big impact.

Another huge benefit of going micro is agility and lower risk. If one influencer’s post flops or if an influencer goes on hiatus, it’s not a big blow – you have a whole team of others contributing. You can also scale up or down quickly by adding more micro-influencers to the mix as needed. This flexibility is useful in fast-changing environments like TikTok. Plus, many micro-influencers are active on multiple platforms (Instagram, YouTube, etc.), so a partnership with them can sometimes extend beyond TikTok, giving you multi-channel exposure.

Tips for successful micro-influencer partnerships:

• Find the right fit: Look for micro-influencers whose niche, style, and values align with your brand. Relevance is more important than follower count. A micro-influencer who specializes in eco-friendly living is perfect if you sell sustainable products, for example.

• Engage authentically: Give influencers creative freedom to present your product in their own voice. Their content will come across genuine if they’re not reading a strict script. Maybe suggest ideas or themes, but let them do what their audience loves.

• Provide perks: Even if you’re not paying big fees, treat your micro-influencers well. Provide free products, discount codes for their followers, or even a small commission per sale (essentially turning them into affiliates). This keeps them motivated and excited to promote your brand.

• Build relationships: If you find a micro-influencer who really moves the needle for you, consider an ongoing partnership. Long-term collaborations can make the influencer feel like a true brand ambassador, and their followers will see their sustained love for your brand – boosting credibility.
  

Micro-influencer partnerships prove that influencer marketing isn’t just a luxury for big companies. In 2025, even the smallest eCommerce seller can harness the persuasive power of relatable TikTok creators without breaking the bank. The result is authentic content, stronger customer trust, and yes – more sales.

UGC Campaigns: Fueling Trust with User-Generated Content

Word of mouth has always been marketing gold, and on TikTok, word of mouth often takes the form of user-generated content (UGC). UGC is basically any content about your brand that isn’t made by you – think videos of real customers unboxing your product, a TikTok of someone using your app in daily life, or a fan doing a funny skit featuring your brand. In 2025, TikTok UGC has taken center stage in digital marketing because it delivers something consumers crave: trust and authenticity.

What makes UGC so powerful on TikTok? It feels real, unscripted, and honest. TikTok users scroll past polished ads, but they stop for stories and genuine moments. A TikTok video shot on an iPhone by a happy customer can often outperform a slick commercial. In fact, 83% of TikTok users say UGC makes brands seem more authentic, and brands using UGC content on TikTok see significantly higher engagement – about 35% higher watch-through rates compared to polished ads. In other words, people are more likely to watch and trust content that looks like it came from “people like me.” No wonder UGC drives roughly 60% of TikTok’s brand engagement these days.

For eCommerce sellers, running UGC campaigns on TikTok is a no-brainer to build credibility and spark viral growth. Here are some ways to leverage UGC in 2025:

• Encourage customers to share: Actively invite your customers to post their experiences. This could be as simple as adding a card in your packaging that says “Tag us on TikTok @YourBrand using #MyBrandStory for a chance to be featured!” People love showing off finds or participating in trends, so give them a nudge.

• Launch UGC contests or challenges: For example, a fitness brand might start a challenge for customers to post their at-home workout using the brand’s gear, with a special hashtag. Offer a prize (store credit, a feature on your official page, etc.) to sweeten the deal. Contests give users a fun incentive to create content for you. As TikTok’s own Branded Hashtag Challenges have shown, a good challenge can generate a flood of UGC and new followers.

• Leverage influencer-UGC hybrids: Sometimes you can partner with micro-influencers specifically to create UGC-style content. This is basically what Stack Influence campaigns do – the influencers post content that feels like UGC (because it essentially is, just by an influencer). You can then repost that content on your own channel (with permission) or even run it as Spark Ads to reach more people. The key is that the content still has that lo-fi, authentic TikTok vibe, even if it’s part of a paid collaboration.

• Feature UGC on your brand’s TikTok (and beyond): Make your customers the stars! Share the best UGC videos on your official TikTok profile (always credit the creators). This not only provides social proof but also encourages more fans to create content in hopes of being featured. You can repurpose UGC on other channels too – for instance, share TikTok UGC clips on your Instagram Stories or in product pages on your website as testimonials. Each piece of UGC can be a mini advertisement that you didn’t have to pay to produce.
  

A great example of UGC in action is the #TikTokMadeMeBuyIt phenomenon. This hashtag – which has literally billions of views – is full of everyday people showing off products they bought because they saw them on TikTok. Smart eCommerce brands are hopping on this trend by tagging their product showcase videos with #TikTokMadeMeBuyIt, effectively tapping into a massive social proof engine. If a product gains enough positive traction, it can even turn into a viral hit where everyone wants to buy it just because “TikTok made me do it.”

Another example: cosmetics brand Glossier used the popular “Get Ready With Me” (#GRWM) format to encourage users to post their skincare routines featuring Glossier products. By letting the story (morning routine, self-care, etc.) come before the product pitch, the campaign felt natural and relatable, leading to tons of engagement. Or consider Chipotle’s #Boorito campaign – a Halloween challenge where fans posted videos in costume to earn a discount, generating a trove of fun UGC that tied back to the brand. These cases show that when UGC is done right – aligning with a trend or community passion – it can explode your reach.

The bottom line: UGC campaigns build trust and community around your brand. In 2025, Gen Z and Millennials want to interact with real stories and peer recommendations on TikTok, not faceless corporations. By integrating UGC into your influencer marketing (and giving your customers a voice), you make your marketing feel more like a conversation than a sales pitch. And that’s exactly the kind of authentic connection that translates into loyalty and sales.

Trend-Based Content: Riding TikTok Waves for Maximum Exposure

TikTok runs on trends – they’re the lifeblood of the platform’s culture and virality. For eCommerce brands, trend-based content is a powerful strategy to boost visibility and stay relevant, as long as you do it right. Trend-based content means tapping into whatever is hot on TikTok at the moment, whether it’s a catchy dance, a viral hashtag, a new filter, or a popular sound clip. The payoff? When you join a trend, you’re more likely to appear on the coveted For You Page (FYP) and get those sweet viral views, because TikTok’s algorithm often rewards content that lots of people are engaging with.

However, trends on TikTok move fast. What’s exploding this week might fizzle out by next month. To capitalize on trend-based content in 2025, you need to be agile and observant. Here are some tips:

• Keep an eye on the TikTok pulse: Spend time on the app (or assign someone on your team to) regularly to see what formats or memes are trending. TikTok’s Discover page (or the 🔍 search) will show you trending hashtags, sounds, and challenges in real time. Also watch your own FYP for recurring themes. If suddenly everyone’s doing a dance to a particular song, or there’s a hashtag challenge gaining steam, think creatively about how your brand could participate early. Catching a trend early is key – you don’t want to be the brand doing last month’s meme (that can come off as out-of-touch).
• Use trending music and sounds: Audio is huge on TikTok. A single sound bite or song can define a trend. Including a trending sound clip in your video can work wonders for boosting your brand’s visibility. TikTok’s algorithm often groups videos by sound, so if you use a popular track, your video has a shot at being shown to users who enjoyed other videos with that track. Of course, ensure the trend or sound aligns with your brand image (and make sure to use licensed sounds or the ones available on TikTok’s library for business accounts).
• Participate in viral challenges and hashtags: If there’s a viral hashtag challenge that fits your brand even loosely, go for it. For instance, if #HolidayHacks is trending and you sell kitchen gadgets, make a TikTok showing a holiday cooking hack with your product. It’s free real estate in a popular conversation. Brands in 2025 are increasingly creating branded hashtag challenges as well – starting their own trend to encourage UGC (like Guess’s famous #InMyDenim challenge which had users show off their denim outfits and garnered huge engagement). Starting a trend is harder than joining one, but if you have a clever idea and seed it with influencer partners, it could take off.
• Be fun and culturally relevant: TikTok users love humor and authenticity. Don’t be afraid to show a lighter side of your brand or hop on a quirky trend, even if it’s a bit silly. Did an audio clip of a funny cat meow go viral? Maybe your pet supplies store can use it in a video of a cat enjoying your product. The key is to be a part of the TikTok community. Show that your brand isn’t just there to sell, but also to entertain and engage. This builds brand likeability.
• Act fast (but don’t force it): There’s a balancing act between jumping on trends and staying true to your brand. It’s usually obvious when a brand shoehorns itself into a trend where it doesn’t belong, and that can come off as cringey or try-hard. Focus on trends that you can naturally fit into or put a relevant spin on. It’s better to miss a trend that doesn’t suit your brand than to do it awkwardly. When you do find one that fits, execute quickly while the topic is still hot.
  

A trend-related win for brands often comes from blending the trend with a bit of creativity. For example, during a popular TikTok “Storytime” trend (where users narrate a story with on-screen text), an online shop might create a video like “POV: You’re opening a package from [Brand]” to ride the POV storytelling wave. Or with the evergreen dance trends – even if you as a founder can’t dance, you could have your team do a quick choreo in the warehouse or show your product dancing (hey, products have moves too!). The goal is to signal that your brand is up-to-date and part of the fun, which makes users more inclined to engage with you.

Remember, TikTok trends are an opportunity to massively amplify your reach for free (or cheap). A single well-timed, trend-savvy video can sometimes do the work of a whole paid ad campaign. By staying nimble and creative, eCommerce sellers can ride these TikTok waves to gain followers, boost brand awareness, and ultimately drive more sales.

Tips for Maximizing ROI and Building Authentic Connections

Finally, let’s talk about making all these strategies pay off. It’s great to run influencer campaigns and join trends, but you should also measure what’s working and double-down on authenticity to get the best return on investment (ROI). Here are some practical tips to maximize your ROI while keeping it real with your audience:

• Set Clear Goals & Track Key Metrics: Before launching any TikTok influencer campaign, define what success looks like. Is it a certain number of website visits? A boost in sales? New followers? Once you have goals, track metrics religiously – TikTok Pro/Business accounts offer analytics, and you can supplement with tools or UTM links. Key performance indicators (KPIs) to watch include engagement rate (likes, comments, shares), video views, follower growth, click-through rate on your bio or link, and conversion rate (how many viewers actually bought something). If you run a hashtag challenge, check the hashtag views and participation (that’s a metric too). By monitoring these numbers, you can calculate your influencer marketing ROI (for example, revenue generated vs. cost of campaign) and identify which tactics or creators deliver the best results.

   

• Use Unique Codes or Links for Influencers: A tried-and-true method for tracking ROI and incentivizing sales is giving each influencer a unique discount code or referral link. For instance, give TikToker @fitnessamy a code “AMY10” for 10% off your protein powder. When her followers use it, you’ll know exactly how many sales came from her videos. This not only helps measure direct ROI per influencer, but the discount also encourages more people to buy – a win-win. Many micro-influencers love this because it gives their audience a perk and often the influencers earn a small commission (affiliate marketing model), motivating them to promote even harder.

   

• Repurpose High-Performing Content: Stretch your content dollars by reusing the best stuff. If an influencer’s TikTok about your product goes viral or gets great engagement, amplify it. You can ask for permission to repost it on your own TikTok page (crediting them), share it on other social media, or even turn it into an ad. TikTok’s Spark Ads feature allows you to take an organic TikTok (like your influencer’s post) and promote it as an ad while retaining its original engagement (likes, comments). This is a fantastic way to boost reach while keeping the social proof and organic vibe. You’re effectively turning a successful piece of influencer content into a broader campaign. Similarly, repurpose UGC videos in your email marketing or product pages to add authenticity. Squeezing more mileage out of content you already have improves ROI.

   

• Engage and Build Community: Don’t treat influencer marketing as a one-way broadcast. Join the conversation to build authentic connections. That means replying to comments on TikTok (both on your brand’s posts and the influencers’ posts about your product). If someone asks “Where can I get this?” under an influencer’s video, hop in and politely provide a link or info. Thank people for their positive reviews, answer questions, even embrace light criticism with grace and humor. This kind of active community management shows that there are real people behind the brand who care. It can turn curious viewers into followers and eventually customers. Additionally, consider creating your own TikTok content like behind-the-scenes clips, founder stories, or customer feature shoutouts. These humanize your brand and complement the influencer content with your own authentic voice.

   

• Foster Long-Term Relationships: The best influencer marketing results often come from ongoing partnerships. If an influencer (big or small) does a great job and truly likes your product, keep that relationship going! Maybe you send them new product launches to test, or collaborate on a series of TikToks. When followers see an influencer talk about a brand repeatedly over time, it reinforces that the love is genuine. It also allows the influencer to get more creative and in-depth with your brand (e.g., a skincare influencer could do an initial unboxing, later a “one month later” results video, etc.). Long-term collabs build a narrative that viewers can follow, strengthening trust and connection. Plus, you save time not having to find new partners constantly. Think of your stable of influencers as an extension of your team.

   

• Embrace Authenticity Over Perfection: Finally, remember that TikTok rewards authenticity. Don’t spend weeks trying to craft the “perfect” glossy campaign that ends up feeling like an ad. Instead, focus on real stories and real people. Encourage your influencers and customers to share honest opinions and creative takes. Sometimes a video with a minor flub or a goofy moment can come across more endearing than a perfectly polished clip. Audiences in 2025 can sense authenticity, and they love it. As one expert insight put it: “Raw beats polished on TikTok. Period.”. So be genuine, have fun with your content, and let your brand’s personality shine through your influencers and community.
  

By implementing these tips, you’ll not only squeeze the most value from your TikTok influencer campaigns, but you’ll also cultivate real connections with your audience. And that’s the ultimate goal – because authentic engagement is what turns a one-time viewer into a loyal customer who sticks with your brand beyond the trends of today.
