Influencer due diligence checklist (2026)

If you work at an agency or brand team, you've probably signed off on a creator recommendation based on a media kit and a follower count. Sometimes that holds up. Sometimes the campaign underdelivers and nobody can explain what was checked before the spend.

Influencer due diligence is the step that turns "they look good on paper" into evidence you can share, defend, and revisit later. This checklist is built for that workflow — conservative, evidence-based, and usable whether you're vetting one creator or a full shortlist.

Before you start

• Define the brief. Niche, platform, audience geography, budget tier, and brand-safety boundaries. Vetting without a brief produces noise.
• Collect handles. Instagram, TikTok, YouTube, Twitch, X, website — whatever is relevant to the campaign.
• Set a documentation standard. Decide what "checked" means for your team: a saved report, a reference number, a client-shareable link.

Step 1 — Surface metrics (5 minutes)

Start with what is publicly visible:

• Follower or subscriber count
• Recent engagement (likes, comments, views) on a representative sample of posts
• Posting frequency and format mix (Reels, static, long-form)
• Disclosed partnerships or sponsored content patterns

Free starting points on Pinkk:

• Free vetting preview — paste a handle for a quick, conservative read
• Fake follower estimator — sanity-check whether follower count and engagement pattern fit together
• Engagement rate calculator — compare against platform benchmarks

These are previews, not verdicts. They tell you whether a deeper audit is worth the time.

Step 2 — Traffic quality signals (10–15 minutes)

Follower count answers "how many." Due diligence answers "where does the attention come from, and does it look coherent?"

Look for:

• Cross-platform presence — strong on one platform but absent elsewhere can be normal or a signal, depending on niche
• Engagement consistency — one viral post vs stable performance across posts
• Search and discovery traces — does the creator appear in search beyond their handle?
• Audience coherence — does engagement scale with reach in a way that fits the content type?

Pinkk's structured vetting reports cover these as confidence-rated findings — not a single pass/fail score. Run a full audit report on any creator, brand, or affiliate profile.

Step 3 — Brand safety and partnership context (10 minutes)

• Recent controversies or reputational noise (news, community reaction, platform enforcement)
• Competitor or conflicting brand partnerships
• Content tone vs your client's risk tolerance
• Regulatory or disclosure context (especially for finance, health, alcohol, iGaming)

For affiliate and iGaming workflows, also review public compliance signals: Affiliate transparency checker.

Step 4 — Campaign fit (5 minutes)

• Does the creator's content format match the deliverable (UGC, integration, dedicated post, long-form)?
• Does their audience geography align with the campaign market?
• Have they promoted similar products before — and how did those posts perform relative to their baseline?

If you're shortlisting multiple candidates, run a profile comparison once both analyses are complete.

Step 5 — Document and share (5 minutes)

Before you put a name in a client deck:

• Save the vetting report (PDF export or private share link)
• Note the report reference number for verification at /verify
• Record the date — due diligence is a point-in-time snapshot

If the campaign runs long, schedule a re-analysis before renewal. Traffic profiles change.

What to avoid

• Treating a percentage as proof. "72% real followers" sounds precise; public data rarely supports that level of certainty.
• Skipping documentation. "We looked at their profile" is not a defence when a client asks what you knew at signing.
• Vetting only at signing. Re-check before renewals and after major platform or audience shifts.

Who this checklist is for

• Agencies vetting shortlists before client presentations — see the agency workflow
• Brand and partnership teams approving budget before contracts — see the brand workflow
• Researchers building repeatable, auditable records over time
