9 have not yet been assessed on the Agency List Score. Alphabetical.About this ranking
What this page ranks
This page ranks 36 of the 42 assessed website optimization agencies in Boston, Massachusetts — the ones carrying a published score — out of 51 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, Website Optimization in Boston, Massachusetts. 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 42, so the strongest award available here is top 5%.
The 9 website optimization agencies not yet assessed are listed on this page but not ranked.
A further 6 were assessed and no published evidence of their work was found, so no score is shown for them.
Paid placement
Partner agencies can buy a labelled placement block above the ranking on this page. It is always marked as paid and is never mixed into the ranked list.
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.
