How to choose an SEO agency in the United States
The US market has agencies at every size and price point, so start by matching the agency to your actual situation rather than picking the biggest name. Ask who will actually work on your account day to day, not just who pitches you in the sales call. Ask directly whether AI-search visibility work, how your brand shows up in ChatGPT, Gemini, and AI Overviews, is included in the retainer or billed as a separate line, since a growing share of US agencies now charge extra for it.
What SEO costs in the United States
Retainers across the country typically run from about $1,500 to $10,000 or more a month. Small local businesses tend to land in the $1,500 to $3,500 range, mid-market companies usually pay $5,000 to $10,000, and enterprise programs run past $10,000. A 2026 Ahrefs survey put the North American average retainer at roughly $2,819 a month, with about half of agencies pricing between $1,500 and $5,000. Competitive metros and regulated industries like law and finance tend to sit at the higher end.

How much does SEO cost in the United States?
Most US retainers fall between $1,500 and $10,000 or more a month. Small local businesses typically pay $1,500 to $3,500, mid-market companies pay $5,000 to $10,000, and enterprise programs run higher still. A 2026 Ahrefs survey found the North American average retainer sits around $2,819 a month, and roughly 48% of agencies price between $1,500 and $5,000. Some agencies now bill AI-search visibility work separately, so ask what is and is not included before comparing quotes.
How long does SEO take to work in the US?
Expect the first signs of movement, like technical fixes and Google Business Profile improvements, within a few weeks. Early ranking gains typically show up in 3 to 6 months, and results that compound into real traffic and revenue growth usually take 6 to 12 months. Competitive metro areas and regulated industries such as law and finance tend to sit toward the longer end of that range.
Should I hire a local SEO agency or a national one?
Both can work well. A local agency tends to know your metro's competitive landscape and can be useful if a large share of your business depends on local search and map-pack visibility. A national agency often has broader team capacity and experience across more industries. What matters more than location is whether the agency has handled businesses like yours before and can show it, since most SEO work today is delivered remotely regardless of where the agency is based.
Is SEO being phased out by AI search?
No. Organic listings still generate the large majority of search clicks, and the technical and authority work behind good rankings is exactly what makes a brand citable in AI answers. What is changing is measurement, buyers now also track whether AI engines name their brand when someone asks a buying question. Ask any shortlisted agency how they measure AI-search visibility.
How are the agencies on this page ordered?
Agencies are ordered by partner tier: Certified Partner first, then Partner, then Unverified. Tier reflects an agency's verification status with AIclicks, not a performance score or a ranking of quality. Unverified profiles were compiled from public search results and have not been claimed by the agency yet, so their details are deliberately minimal. Any agency can claim its profile to correct and expand it.
