The top three by evidence-weighted score are BizIQ (71/100), Fasturtle (58) and CadenceSEO (53). 1 of them has documented SEO audit work for clients in Phoenix itself. No paid placements; every position below cites its sources. 16 more Phoenix SEO agencies have no SEO audit claim on file yet and are listed unranked.
Ranked agencies have at least one claim from an outside source that names an audit the agency delivered: a technical, site, content or backlink audit, what it found, and what changed after; official case studies and third-party reviews weigh most, profile tags least.

On the Phoenix SEO list, but nothing on file names SEO audit work. One sourced claim moves an agency into the ranking.
Evidence-weighted ranking 2026.09.1: each agency is scored on the SEO audit 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.
An audit earns its price when it separates technical blockers, content gaps and conversion problems, and says which to fix first. A crawl export is not an audit: it is the raw material for one.
