Before you sign a contract with an influencer, their media kit is your clearest window into what you're actually paying for. A polished deck can hide weak audience quality, inflated numbers, or misaligned brand values—so knowing what to scrutinize saves you budget and prevents wasted campaigns.
Verify Audience Size and Breakdown
Start with the raw numbers, but don't stop there. An influencer claiming 500K followers means nothing if 60% are bots or inactive accounts. Request platform-specific follower counts across Instagram, TikTok, YouTube, or LinkedIn—whichever channels matter for your campaign.
Look for demographic breakdowns by age, gender, location, and interests. If you're selling skincare to US women aged 25–40, an influencer with a massive following skewed toward 16–24 year-old international audiences isn't the right fit, regardless of total reach. Red flags include vague statements like "mostly young adults" without actual percentages.
Examine Engagement Metrics (Not Just Follower Count)
Engagement rate is the actual health indicator. Calculate it yourself: (total engagements ÷ follower count) × 100. Anything between 1–5% is solid for established creators; micro-influencers (10K–100K followers) often hit 5–15%. If someone with 300K followers averages 200 likes per post, their engagement is cratering around 0.07%—a sign of a purchased audience.
Ask for 30-day engagement averages, not cherry-picked post examples. Video completion rates on YouTube or watch time on TikTok matter too, especially if your campaign hinges on storytelling rather than quick awareness.
Check Audience Authenticity Tools
Media kits rarely include third-party verification, but you should ask for it. Tools like HypeAudience, Social Blade, or Influee analyze account health and flag suspicious activity patterns. A creator who refuses a quick audit or becomes defensive is a warning sign.
Look at follower growth patterns in their kit: steady, natural growth is healthy; sudden spikes suggest purchased followers or a viral moment (context matters). Legitimate influencers often include these checks proactively.
Assess Content Alignment and Brand Safety
Scroll through their actual feed for 2–3 months. Does their aesthetic match your brand? Do they promote competing products, or work with 10+ brands simultaneously (diluting focus)? A beauty influencer shilling discount supplements and cryptocurrency NFTs may not align with your premium skincare launch.
Check their posting frequency too. Someone posting sporadically (once every two weeks) won't maintain momentum for your campaign. Consistent weekly or bi-weekly posting signals they're actively invested in their audience.
Review Deliverables and Pricing Tiers
A solid media kit breaks down package options by deliverable type: Instagram Reels, Stories, TikTok videos, YouTube long-form content, or blog posts. Prices should reflect platform differences—YouTube pre-roll ads typically cost more than Instagram Stories because they demand higher production.
Typical 2024 rates for US-based creators:
- Micro-influencers (10K–100K followers): $500–$5K per post
- Mid-tier (100K–1M followers): $5K–$25K per post
- Macro (1M+ followers): $25K–$100K+ per post
If pricing seems suspiciously low (50% below market rate), quality usually reflects that. If it's double the range and results aren't guaranteed, negotiate inclusion of specific performance metrics.
Confirm Contract Terms and Rights
The media kit should mention usage rights. Can you repost content on your own channels? For how long? Are they exclusive during the campaign period? Some creators allow 90 days of reposting; others restrict it to 14 days. Get specifics in writing.
Turnaround time matters too. Standard is 2–4 weeks from approval to publication. Rush campaigns cost 20–40% more. Ask whether revisions are included or billed separately.
Red Flags to Walk Away From
Influencers who won't share analytics, claim "partnerships are confidential" (audience metrics aren't), or use only vague language about reach deserve skepticism. Similarly, anyone pressuring you to pay upfront without a signed agreement is risky.

Frequently Asked Questions
Q: What engagement rate should I expect from an influencer I'm considering? Aim for 2–5% on Instagram and YouTube for established creators; micro-influencers often exceed 5%. Engagement below 1% usually indicates a low-quality or purchased audience.
Q: Should I negotiate pricing if the media kit seems expensive? Absolutely. Most creators have flexibility, especially for longer contracts (3+ posts) or bundled packages. Expect 15–25% discounts for commitments.
Q: How do I know if an influencer's audience matches my target customer? Request detailed demographic data and ask them to walk you through their audience insights. Cross-reference with your customer personas; if there's less than 70% overlap, keep looking.
