SEO Agencies in the USA

Use the filters above: set your industry and service needs, then sort the United States list by Agency Score. Open three to five profiles and look for case studies from your market, client reviews, and named team members. Book calls with your shortlist before deciding. Local knowledge shows up fast in conversation, so ask each agency what they know about your customers.

Every agency here applied for inclusion and passed screening: we verify history, expertise, and performance, then assign an Agency Score from 0 to 100 built on website traffic, domain trust, technical SEO health, and verified certifications like Google Partner. The United States list sorts by that score, so the agencies at the top earned their position with measurable results, not ad spend.

Local agencies bring market knowledge, a shared language, and time zone alignment — all of which matter for local campaigns and businesses serving United States customers directly. Remote agencies widen your talent pool and often cost less. Many businesses split the difference: a local partner for strategy and market insight, remote specialists for execution. The filters above let you compare both options side by side.

Match the agency to your biggest gap. Full-service SEO agencies suit companies that need strategy, content, technical and links under one roof. Technical specialists fit large or JavaScript-heavy sites with crawl and indexing problems. Content-led agencies help when rankings depend on publishing at scale. Local SEO agencies serve businesses with physical locations. Ecommerce, SaaS and enterprise specialists bring industry playbooks. Use the industry and service filters to narrow the list.

Most SEO agencies charge a monthly retainer, typically from $1,000 for small businesses to $10,000+ for enterprise programs, covering a fixed scope of hours or deliverables. Project pricing applies to audits, migrations and one-off content builds. Hourly consulting rates run roughly $100 to $300. Performance-based deals exist but are rare. Compare what each retainer includes; profiles here list pricing ranges where agencies share them.

Increasingly, yes. Generative engine optimization means getting your brand cited in answers from ChatGPT, Perplexity, Gemini and Google AI Overviews, and it builds on the same foundation as SEO: crawlable pages, clear entity signals, structured data and authoritative mentions. Not every agency has moved there yet. Browse AI SEO agencies or use the service filter above to see which teams in the United States offer it, and ask candidates how they track AI citations, not just rankings.

The largest clusters sit in New York (24 agencies), Los Angeles, Chicago, Miami and Austin, followed by San Francisco and Las Vegas.

The catalog comes with SE Ranking's Agency Pack, an add-on to Core and Growth annual subscriptions. Join, complete a short application form about your services and clients, and your profile appears in the United States list plus every service and industry category you cover. Agencies with complete, verified profiles get more visibility within their score band.

Businesses filter this catalog by location, service, and industry, then contact agencies straight from their profiles. Your profile also appears across category pages, so a United States agency doing ecommerce work shows up in several lists at once. The Agency Score does the trust-building; your case studies and response speed do the closing.
