We started from the ten agencies on our previous US list and Clutch's US SEO rankings. We kept firms with a Clutch rating of 4.7 or higher and a reviewed result for a US client.
We left out agencies whose own pages rank in Google's US top 10 for "top SEO companies", such as Coalition Technologies, OuterBox and Thrive. We also spread the list across US regions, from the Northeast to the West Coast.

SEO in the USA costs from about $1,000 for a starter project to several thousand dollars a month for a full program. Clutch hourly rates on this list run from $100 to $199. Two agencies publish a monthly price: Loopex Digital from $1,500 and Searchbloom from $3,000.
Prices rise with the number of locations and the competition in each city. A roofer in Phoenix and a law firm in Manhattan face very different costs. For what each budget buys, see our SEO pricing guide.
| Starting point | Agencies on this list | Hourly rate (Clutch) |
|---|---|---|
| From $1,500/mo | Loopex Digital | Month to month |
| From $3,000/mo (published) | Searchbloom | $100 to $149 |
| $1,000+ project | Big Leap, SmartSites, WebFX, Straight North, SEO Brand, Intero Digital | $100 to $149, or not listed |
| $5,000+ project | Sure Oak | $150 to $199 |
Most US SEO companies on this list start at a $1,000 project on Clutch. Hourly rates run from $100 to $199. Monthly programs usually start between $1,500 and $3,000. Loopex Digital starts at $1,500 per month, month to month, and Searchbloom publishes SEO from $3,000 per month.
Not always. A local office helps with local press and neighborhood knowledge. A remote agency can still rank you if it builds real location pages, manages your Google Business Profile and earns local links. Ask for a result for a client in your state before you sign.
Most US businesses see early gains in three to six months. Competitive categories like law, home services in large metros or finance often take six to twelve months. Map results can move faster once your Google Business Profile, reviews and citations are fixed.
For a small business, Loopex Digital suits owners who want month to month terms and AI search tracking. SEO Brand suits contractors and home services firms. Searchbloom suits firms that can budget $3,000 per month and want an SEO-first team.
A national agency is usually the better fit. It can manage a Google Business Profile for each address, build a location page for each market and report calls per location. Big Leap and SmartSites both work with multi-location brands on this list.
Yes. AI tools name businesses that appear in reviews, directories, local lists and clear websites. Run the five prompts above to see where you stand today. Then ask any agency how it measures AI citations, not just whether it offers AI search work.
