About this ranking

What this page ranks

This page ranks 3 of the 5 assessed backend development agencies in Atlanta, Georgia — the ones carrying a published score — out of 8 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, Backend Development in Atlanta, Georgia. 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 5, so no award can be issued here.

The 3 backend development agencies not yet assessed are listed on this page but not ranked.

A further 2 were assessed and no published evidence of their work was found, so no score is shown for them.
