Scoring

How we rank influencer marketing agencies

17 agencies and 7 creator platforms sit in the live set. The Leader is the highest Index Score on the rubric below — not a paid slot, and not because a shop owns this site.

Last researched: 26 August 2026. Next review: November 2026. Desk: Best Influencer Marketing Agencies editorial desk. How we rank

What the Index Score means

Index Score is a number out of 10. Stars on each card are that score divided by two. Badges: Leader (highest agency score in the live set), High Performer (clear specialist or scaled independent), Contender (in the set, narrower published proof). A platform score is not an agency rank.

Scoring factors and weights

Weights sum to 100%. Missing proof on an axis scores zero on that axis; it does not invent a midpoint.

Index Score weights
FactorWeightWhat counts
Published proof of work35%Named clients, case studies, and whether reporting is described as revenue, codes, or pixels rather than estimated media value. Unsourced “we work with Fortune 500” language scores zero on this axis.
Platform-partner access25%TikTok, Meta, and YouTube partner badges that can be checked on the agency site or a platform directory. A slide that lists ten platforms without a badge does not count.
Ownership clarity20%Who owns the shop, whether a founder still runs it, and whether a holding company, PE firm, or public listing sits behind the logo. Hidden parents are a penalty, not a bonus.
Footprint and bench20%Published offices, markets, and headcount band. A “global” claim with one city on the contact page does not score as a global bench.
  1. 01

    Sources used

    Each field is taken from the agency’s own site, a directory profile (Clutch, Inc., LinkedIn), a platform partner page, or named press (acquisition, award). If we cannot source it, we mark it unverified. “Not found” is not the same as “does not exist.”

  2. 02

    How client claims are verified

    A client counts when the agency names it on a public page or a bylined case study. “Fortune 500 brands” without names does not count. Revenue figures such as “$150M+ generated” count only when the agency publishes them; they are labeled as the agency’s claim and cited.

  3. 03

    How platform partnerships are verified

    TikTok, Meta, and YouTube badges count when they appear on the agency site or a platform directory we can open. A pitch-deck logo wall is not a source. Absence of a public badge is unmarked unverified — not proof the badge does not exist.

  4. 04

    How ownership is verified

    Parent, PE, or public listing comes from the about page, an acquisition announcement, or a filing. Founder-led independent is scored only when no parent is published. Hidden parents are a penalty.

  5. 05

    How often scores are updated

    Published pages sit on a 180-day review clock. Dataset last researched: 26 August 2026. Next review: November 2026. A stale claim is treated as a wrong claim.

  6. 06

    Whether agencies can pay to be included

    No. Rankings are not for sale. There is no featured slot, no affiliate cut on retainers, and no paid review. Vendor sites are linked as sources the same way a software index links a product homepage.

    Who conducts the research

    Honest fit sections

    Every comparison names at least three reasons a buyer might pick the other shop. If we cannot write three, we do not publish.

Common questions

Where do the facts on each comparison page come from?
Each field is taken from the agency’s own site, a directory profile, or third-party coverage. If it cannot be sourced, it is marked unverified. “Not found” is not the same as “does not exist.”
What is an Index Score?
A score out of 10 that weights published proof of work (35%), platform-partner access (25%), ownership clarity (20%), and footprint (20%). Stars are the score divided by two. Missing proof on an axis scores zero on that axis.
Can an agency pay for a higher rank?
No. Rankings are not for sale. There is no featured slot, no affiliate cut on retainers, and no paid review. Vendor sites are linked as sources the same way a software index links a product homepage.
How often are profiles reviewed?
Published pages sit on a 180-day review clock. Last researched 26 August 2026. Next review November 2026. Headcount, parents, and clients change; a stale claim is treated as a wrong claim.

Do creator platforms use the same rubric as agencies?
The four axes are the same so scores are comparable, but platforms are a separate list. A CreatorIQ or GRIN score is not an agency rank. Software is scored as software.

Rankings that use this rubric

Same weights and dates. Each page keeps shops that match a brief. Row order on those pages is fit for the brief. The main index is still sorted by Index Score. A shop can be first on one brief and second or third on another without a score change.

Corrections

If you work at a shop in this directory and a fact is wrong, send a public source. We update the record and bump the review date.
