Micro-influencers are creators with roughly 10,000 to 100,000 followers. To find micro-influencers for your brand, start by defining your customer and niche. Then search where those creators already post, like hashtags, location tags and your own tagged posts. Check each creator's engagement and audience before you shortlist and reach out. An influencer search tool does the filtering much faster.

This guide is for small businesses, e-commerce brands and startups running their first micro-influencer campaign, or looking for better creators than the ones they've tried so far.

What is a micro-influencer?

Influencers are usually grouped into tiers by follower count. Definitions vary by platform and agency, but these ranges are the most common:

• Nano (1,000–10,000): Local businesses, gifting, UGC and tight-knit communities
• Micro (10,000–100,000): Niche audiences, local reach and sales-focused campaigns
• Macro (100,000–1 million): Broad reach within a category
• Mega (1 million+): Mass awareness

Micro vs macro influencers

Macro-influencers reach more people with each post, cost more per post and usually cover broader topics. Micro-influencers reach fewer people per post, cost less and usually serve a specific niche or city.

For a small brand, that means you can test several micro creators for the cost of one macro post and see which audiences actually buy. For example, Triller spent $1,500 across 40 nano and micro creators booked through Jem Social and tracked more than 10,000 conversions at about $0.15 each (see the full breakdown). Results vary by product and creator, so judge each creator on their own numbers. For a deeper comparison, see our breakdown of micro vs macro influencers.

Step 1: Define who you're looking for

Write these down before you start searching. They become your filters.

• Customer: who buys from you, including age, location and interests.
• Niche: the topics a creator should cover. "Home workouts for new moms" is a better filter than "fitness."
• Platform: Instagram, TikTok or YouTube, based on where your customers spend time and what kind of content you need.
• Location: essential for local businesses and events. If you ship products, make sure the creator's audience lives where you ship.
• Follower range and budget: for example, 10,000 to 50,000 followers and a set budget per creator. The free Influencer Rate Calculator helps you set a realistic number.
• Goal: sales, sign-ups, foot traffic or content you can reuse in ads.

Step 2: Search for micro-influencers for free

Start with your own followers and tagged posts

Check your tagged posts and mentions on Instagram and TikTok, then look through your followers and customers for people who post regularly. Creators who already use your product make the most believable content, and they're easier to book.

Search niche hashtags and keywords

Search specific hashtags like #oilyskincare instead of broad ones like #skincare. Search keywords too, since Instagram and TikTok both match captions. Look for creators whose posts get comments consistently, not just one viral video.

Search by location to find local influencers

Use location tags for your city or neighborhood and search terms like "[city] foodie" or "[city] mom." For a local business, this is the fastest free way to find creators whose followers can actually visit. You can also browse local Instagram influencers on Jem Social.

Look at your competitors' partnerships

Open a competitor's tagged posts and look for the "Paid partnership" label or #ad. These creators already work with brands in your category. Ask whether they have an exclusivity agreement before you make an offer.

Follow the suggestions

When you follow a creator you like on Instagram, it suggests similar accounts. Use those suggestions to find more creators in the same niche.

Step 3: Use an influencer search tool to go faster

The free methods work, but a single shortlist can take hours, and you can't easily filter by engagement or audience location. An influencer search tool does that filtering for you.

With Jem Social, you can search 30M+ creators and filter by niche, city, follower count, engagement rate and rate. You can also type in your website URL and get matched with creators who fit your brand. When you find a fit, you can invite them with a brief, send a contract and pay through escrow on the same platform.

For example, a gym in Austin could search for fitness creators on Instagram in Austin, TX with 10,000 to 100,000 followers and an engagement rate above 2%. That's a shortlist of local micro-influencers from one search instead of an afternoon of scrolling.

Step 4: Vet every creator before you reach out

Check each creator on your shortlist for:

• Engagement rate: likes plus comments, divided by followers, times 100, averaged over their recent posts. Compare creators of similar size in the same niche rather than holding everyone to one number. The free Engagement Rate Calculator does the math.
• Comment quality: real questions and conversations are a good sign. Rows of emojis or generic "Nice pic!" comments can point to bots or engagement groups.
• Follower growth: a sudden jump of thousands of followers with no viral post to explain it can mean bought followers.
• Audience location and age: if your tool doesn't show it, ask the creator for an Insights screenshot.
• Past sponsored posts: see how they worked products into their content and whether sponsored posts perform close to their normal posts.
• Brand fit: their tone, values and anything in their post history you wouldn't want next to your brand.

Step 5: Reach out and set clear terms

• Send a personal message. Mention a specific post you liked, explain why they fit and say what you're offering: a fee, product, commission or a mix.
• Share a clear brief. Include deliverables, deadlines, key messages, do's and don'ts, and how you plan to use the content.
• Require disclosure. Creators must clearly disclose paid and gifted posts under the FTC's Disclosures 101 for Social Media Influencers. Put it in the brief and the contract.
• Put it in writing. Agree on payment terms, revisions and usage rights before any content is made, and pay when the work is approved.

Step 6: Track results and rebook the winners

Give each creator their own discount code or tracking link so you can see sales or sign-ups per creator. Divide what you paid each creator by the results they drove to get your cost per result. Rebook the creators who performed and replace the rest. The free Influencer Marketing ROI Calculator helps you compare campaigns.
