What this page ranks
This page ranks 6 of the 11 assessed personalization and segmentation agencies in United States — the ones carrying a published score — out of 15 listed.
The score measures how well an agency documents its own work in public — named clients, quantified outcomes, and whether those outcomes are attributed to the agency rather than described as the client's own results. It does not measure client satisfaction, price, or availability.
Cohorts and awards
Agencies are compared within a cohort — here, Personalization and Segmentation in United States. A cohort must be large enough to express the band being awarded: at least 8 assessed agencies for a top 25% award, 20 for top 10%, 40 for top 5%, and 300 for top 1%. This one holds 11, so the strongest award available here is top 25%.
The 4 personalization and segmentation agencies not yet assessed are listed on this page but not ranked.
A further 5 were assessed and no published evidence of their work was found, so no score is shown for them.
Paid placement
The Partner agencies in the labelled block at the top of this page pay for that placement and carry a direct link to their own website.
Placement is paid; it does not affect the ranking, cohort membership, or any agency's score. Ranking position, cohort membership and the score itself are not for sale.
