On the Los Angeles SEO list, but nothing on file names technical SEO work. One sourced claim moves an agency into the ranking.
No technical SEO claim on file yet.
Sources on file say the vendor offers technical SEO; no case study or client review documents the work yet.
Only Vendar profile tags name technical SEO; no outside source on file yet.
Evidence-weighted ranking 2026.09.1: each agency is scored on the technical SEO query from claims with sources. Evidence for this query 30 · Fit to this query 25 · Capability depth 15 · Reliability 10 · Transparency 10 · Reputation 5 · Market credibility 5, minus penalties; confidence is shown separately. Paid visibility never changes the order of a listing. The points, the claims and the limits behind every position are on its card above; the criteria, penalties, eligibility and ordering rules are on How we rank.
Technical work is measured in shipped fixes, not in findings. The question is whether the agency can get changes into your codebase and keep them from regressing at the next release.
