About this ranking

What this page ranks

This page ranks the 11 frontend development agencies in Los Angeles, California that have been assessed on the Agency List Score, out of 14 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, Frontend Development in Los Angeles, California. 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 3 frontend development agencies not yet assessed are listed on this page but not ranked.
