Most "best SEO agency" lists are sold, not researched.

Search for an SEO company and you land on directories where the top three slots are paid placements, review sites where five-star ratings are collected by the agency being reviewed, and listicles written by the agencies themselves.

SEO Companies Hub takes the opposite approach: 512 SEO companies across 5 countries and 68 regions, each tied to the place it actually operates from, each scored by a published formula that only uses facts you can verify yourself.

How listings are compiled

• Companies are added editorially from public information: their own site, published pricing, team size and market focus.
• Every listing is tied to one primary US state and city, so state pages only show agencies genuinely based there.
• Pricing shows a monthly retainer floor where the company publishes or confirms one — never an invented range.
• Services and industries reflect what the company markets itself as doing, not everything it will accept work for.
• We do not publish star ratings, testimonials or results we cannot verify.

The Hub Score

Every company carries a deterministic Capability Score built from operating resilience, delivery capability, sector evidence, commercial clarity and capacity. Evidence Confidence is published separately, and the formula is available in full so you can recalculate any score yourself — and disagree with the weighting if you want to.

Who this is for

Marketing leads and founders running a shortlist. Whether you need local SEO for one city, enterprise technical work, or an international programme across several countries and languages, the directory is designed to narrow the field before the first sales call.
