SEO Data Bench puts SEO APIs on the witness stand

seodatabench.com Observed source

Editorial interest 82/100 Selection signal · not a rating of the site

A reproducible benchmark comparing SEO API coverage, latency, failures, rankings, and cost across fixed query cohorts.

Landing page captured for the 2026-09-15 issue.

Field notes

The benchmark fixes a cohort of 50 queries and 20 domains, then sends it through named routes including DataForSEO, Google Ads, SE Ranking, Serpstat, SerpAPI, and Moz. The listed run records 314 calls, 284 valid responses, and a $1.99 observed cost, with raw CSV material and reproduction commands linked from the catalogue. Coverage is incomplete by design: Ahrefs, Majestic, and Semrush are excluded because the site lacked a plan or credential.
