How do you decide which SEO companies get listed in United States?

A company is listed when we can verify that it operates from a specific state in United States, that it delivers SEO as a core service rather than an upsell, and that its founding year, headcount band and pricing posture are documented publicly. Listings are compiled editorially — no company can buy an entry or a position.

What is a normal SEO retainer in United States?

Retainer floors on this page are published in USD and represent the minimum engagement each company accepts, not what a typical client spends. Screen on scope: monthly technical work, content volume, link acquisition and reporting cadence. Two identical floors can hide very different amounts of senior time.

Should I hire an agency in my own state?

For local and multi-location search, a nearby agency that knows the regional press, directories and language nuance has a real advantage. For national, ecommerce or international programmes, discipline depth beats proximity. Because every listing is tied to its true operating base, you can filter deliberately either way.

How often is the United States directory updated?

Market facts — language, currency, domain conventions, dominant engines — are re-checked on a fixed cycle, and each profile carries its own review date. New companies are added as research is completed rather than in bulk, so counts move gradually.

How the Hub Score on this page is calculated

100 points across five factors, each computed from a fact you can check yourself. Nothing here is bought, voted on or averaged from review sites.

15 ptsOperating resilience — 3 points under 3 years; 6 at 3-5; 9 at 6-10; 11 at 11-15; 13 at 16-20; 15 at 21+ years. Tenure is useful evidence of continuity, but diminishing bands prevent age from dominating the score.
25 ptsDelivery capability — A monotonic diminishing-return curve: 1 service = 6, 2 = 10, 3 = 14, 4 = 17, 5 = 20, 6 = 22, 7+ = 25. Additional documented capability can reduce hand-offs, while diminishing returns limit incentives to pad service lists.
25 ptsSector evidence — Industry coverage contributes 10, 14, 16 or 18 points; 1, 2 or 3+ source-linked case studies add 3, 5 or 7 points. Industry coverage establishes relevance; substantive case studies add depth. Diminishing returns stop a long tag or case list from overwhelming the score, while overall source coverage remains a separate confidence measure.
20 ptsCommercial clarity — 4 for a live site + 6 for a disclosed entry floor + 5 for a stated pricing model + 5 for a specific best-fit client statement. The model rewards buyer-facing commercial clarity, not higher prices or a preference for retainers over projects. Source depth is tracked separately in Evidence Confidence.
15 ptsDelivery capacity — Team bands map monotonically: 10-20 = 5, 20-50 = 8, 50-150 = 11, 150-250 = 13, 250-500 or 500+ = 15. Headcount is treated as capacity, not quality. Larger teams are no longer penalised through an unvalidated ideal-size curve.

What United States actually demands

The deepest agency market in the world and the most fragmented: national enterprise shops, regional generalists and single-vertical specialists all compete for the same queries.

State and metro-level competition varies enormously — a Texas or Florida local pack is a different fight to a Wyoming one.
Spanish-language search is a real second market inside the US; es-US pages need their own hreflang treatment, not a copy of es-MX.
Retainers are quoted excluding tax and usually monthly, with 6–12 month initial terms.
Multi-location brands need location pages plus verified Google Business Profiles per branch, not a single national page.
