How to vet an influencer before paying them

Paying a creator before you have checked them is the most common and most avoidable mistake in influencer sponsorships. Follower counts are easy to inflate, screenshots are easy to edit and a charming pitch costs nothing. This guide walks through a due-diligence routine you can run in under an hour for a typical deal, and the evidence that should carry the most weight.

1. Check whether the audience looks real

Audience authenticity is about whether the people following a creator are real, relevant and reachable. You rarely get certainty, but you can spot warning signs.

• Growth shape. Steady growth is normal. Sudden vertical jumps with no matching viral post or press can point to purchased followers or a giveaway-driven spike.
• Audience geography and language. If a creator sells to US shoppers but most of their audience sits in countries they never mention, the reach may not convert.
• Comment quality. Look for specific, varied comments from accounts with real histories. Walls of emoji, generic praise and repeated phrases are a red flag.
• Native analytics, not screenshots. Ask for an export or a screen-share of the platform's own analytics. Better still, use a connected-account check so the data comes straight from the platform.

2. Judge engagement in context

An engagement rate means little without a benchmark. A 2% rate can be excellent in one niche and weak in another, and small creators usually out-engage large ones. Compare against creators of a similar size and topic, and look at the last 10 to 20 posts rather than one standout video. Check views as well as likes: a big gap between followers and typical views suggests a passive or inflated audience.

3. Review brand safety

Scroll back at least six months. Look for controversies, deleted posts that were archived elsewhere, misleading health or money claims and competing sponsors in your category. Check how the creator handled past paid partnerships: did they label them clearly? A creator who ignores disclosure rules becomes your legal and reputational risk too (see our FTC disclosure checklist).

4. Look for a delivery record

Past performance as a sponsorship partner matters as much as audience size. Ask for two or three references from brands they worked with and contact them. Ask whether the creator delivered on time, followed the brief, handled revisions professionally and disclosed correctly. Campaigns confirmed independently by both the creator and the sponsor are far stronger evidence than a creator's own list of past brands.

5. Confirm the person and the business

• Does the account match the email domain, media kit and payout details?
• Is there a consistent presence across platforms, or a freshly created profile?
• Can they provide a legal name or business entity for the contract?

The pre-payment checklist

• Audience growth looks organic, with no unexplained spikes
• Audience location and language match the campaign market
• Engagement and views compared with creators of similar size and niche
• Analytics verified from the platform, not only screenshots
• Six months of content reviewed for brand safety
• Past paid posts were disclosed clearly
• At least two brand references contacted
• Written contract covers deliverables, deadlines, usage rights and payment terms
• Payment held in escrow or tied to delivery, not paid in full up front

A note on fake followers and legal risk

In the US, the FTC's rule on fake reviews and testimonials, in force since late 2024, also restricts buying or selling fake social media indicators such as followers and views to misrepresent influence in commerce. Working with a creator who inflated their numbers is not just a wasted budget; it is a risk worth avoiding. This is general information, not legal advice.

How Kitscore speeds this up

Kitscore turns this checklist into a single evidence-backed view. Each creator has a Trust Score built from audience authenticity, engagement quality, brand safety and content consistency, plus a Confidence Rating that shows how much of the score rests on verified data rather than self-reported claims. Sponsors can unlock a full evaluation and a decision memo. See how the score works or a sample decision memo, or download the pre-campaign checklist (PDF).
