How to buy SEO in the USA: running a procurement you can defend
The shape of the American agency market, the paperwork that protects you, and how to score three proposals against one scope instead of against each other.
Published by AI Knows Us · Updated 12 October 2026
Buying SEO in the USA works best as a short procurement rather than a search for the best firm. Write a one page brief describing your business, your site, your constraints and what you want in ninety days. Send the identical brief to three suppliers from different tiers of the market. Score the replies on one sheet. The firm that reads your brief closely and tells you something true about your own site before it pitches is almost always the right answer, and the process takes about three weeks.
Below: how the American supplier market is tiered, the engagement models, what drives cost, the brief, the first call, red flags, the paperwork, and how to measure.
The tiers of the American market
Five kinds of supplier compete for the same searches, and they are built for different buyers.
- Holding company and enterprise agencies. Multi channel, process heavy, built for large brands with procurement departments. You get governance and scale, and search is usually one line inside a larger media relationship.
- Mid market independents. Thirty to two hundred people. The volume of the market. Real teams, defined processes, and account management between you and the practitioner.
- Boutiques and specialists. Five to thirty people, often focused on one vertical or one discipline such as technical SEO, ecommerce or digital PR. Usually the strongest per dollar when their specialism matches your problem.
- US front with offshore delivery. American account management, production elsewhere. A legitimate model that works well when it is disclosed, and a problem only when it is hidden.
- Independent consultants. Senior people selling diagnosis, strategy and oversight by the day rather than execution by the month.
Shortlist across tiers, not within one. A boutique, a mid market independent and a consultant will give you three genuinely different reads on the same problem, which is the point of running three.
National reach changes what you are buying
If you sell nationally, the work is content depth, site architecture and authority rather than listings and reviews. Three consequences. Volume matters more, because you are competing for broad topics rather than a city. Regulated categories carry extra cost, since health, legal and financial content needs qualified review and a documented approval path. And if you also have physical locations, location pages and Business Profiles are a separate workstream with separate resourcing, not a bullet inside the retainer.
Engagement models
| Model | Suits | Settle this first |
|---|---|---|
| Monthly retainer | Continuous content, technical and authority work | The monthly deliverable list, and the ramp in the first sixty days |
| Fixed project | Audit, migration, information architecture, schema rollout | Acceptance criteria, so finished is a fact rather than an opinion |
| Hourly or day rate | Advisory work and oversight of your own team | A monthly cap and a named approver for anything above it |
| Performance or revenue share | Narrow cases with one dominant transaction and clean tracking | Which metric, measured in your systems, and what prevents cherry picking |
| Retainer plus projects | Most engagements past the first year | Separate invoice lines, so each budget is visible |
What drives the price
- Seniority mix. The strongest predictor of cost and of quality. Ask how many hours of the senior practitioner are in the plan.
- Content volume and depth. Usually the largest line. Expert interviews, original data and design all raise it.
- Category competitiveness. Legal, insurance, home services and health are contested by large budgets, so the work needed to compete there is larger.
- Technical debt. An old platform, slow templates and crawl waste convert into engineering hours before content earns anything.
- Compliance load. Legal or medical review of every page is a real cost and a real schedule.
- Authority work. Genuine digital PR costs more than outreach because it involves real relationships and real stories.
- Pass throughs. Tools, design, video, translation. Keep these visible and approved in advance.
Write the brief before you talk to anyone
One page is enough, and it is the highest leverage hour in the whole process. Include: what you sell and to whom, your platform and who can change it, the three outcomes you want in ninety days, your internal capacity for approvals and developer work, what you have already tried, and how you want to be reported to. Send the same page to every supplier. Proposals written to one brief can be compared; proposals written to five different conversations cannot.
The first call
- "What did you notice on our site before this call?" Good: something concrete and checkable. Weak: a description of their process.
- "Who does the work, where are they, and can I meet them?" You want names, roles and locations. A straight answer about offshore production is a good sign, not a bad one.
- "Show me two pages you shipped in the last year in a category like mine." Live URLs, not dashboard screenshots.
- "What do you need from us each month, and what happens when we are late?" Strong firms raise client delay before you do.
- "Tell me about an engagement that did not work, and why." The best firms answer this best, because they have diagnosed their own misses. Weigh it heavily.
- "Do you work with our competitors, and how do you handle that?" Ask early, get it in the contract.
Red flags
Google's guidance on whether you need an SEO is direct about the first one: "No one can guarantee a #1 ranking on Google. Beware of SEOs that claim to guarantee rankings, allege a 'special relationship' with Google, or advertise a 'priority submit' to Google." It also warns about firms that will not explain their methods, firms that arrive by unsolicited email, and firms that ask for links back to themselves.
- A proposal and a price before anybody asked about your business.
- A fixed count of posts or links per month as the headline deliverable.
- Reporting on positions for phrases with no demand, or on impressions alone.
- Work kept inside the agency's own tools and logins.
- Auto renewal with no notice window and nothing due in month one.
- Refusal to disclose subcontractors or production locations.
Scoring the proposals, and the paperwork
Put every proposal on one sheet with the same rows: ninety day deliverables with dates, owner per deliverable, senior hours, content volume and author, engineering dependency, reported metrics and their source, pass throughs, term and notice, and the exit handover list. Score each row rather than forming an overall impression.
American engagements usually sit under a master services agreement with a statement of work attached. Keep commercial terms in the agreement and keep the deliverables in the statement of work, so scope can be renegotiated each quarter without reopening the contract. The clauses worth insisting on: ownership of content, code and documentation; your accounts stay yours at all times; subcontractor disclosure; confidentiality that flows down to subcontractors; a notice period with deliverables due during it; and a named escalation contact with a response time.
Measuring the work
Agree two or three numbers before the first invoice, taken from your systems rather than theirs. For most national businesses: organic revenue or qualified pipeline, organic clicks to the pages that make money, and indexed coverage of newly shipped pages. Pass landing page and source into your CRM at form submit, and add one self reported source question to the form, which routinely explains more than analytics alone. Review monthly against the deliverable list and quarterly against the numbers. Month one is judged on the diagnosis.
This page covers running a US SEO procurement: market tiers, engagement models, cost drivers, the brief, vetting, contracts and measurement. For current rates, send one brief to three suppliers across tiers and compare the ninety day plans. For paid media buying and creative production, use a separate brief.
buy SEO in the USA: asked and answered
Do I need a US based agency?
You need senior people who understand your market and a clear line of accountability. Plenty of excellent delivery happens outside the United States. What matters is whether the model is disclosed, who holds the relationship, and whether the hours overlap enough for working sessions.
How long should the first contract be?
Three to six months with a thirty day notice period is a fair starting point for a retainer, and a fixed project is better still for a first engagement. Longer terms are reasonable once you have seen the work.
How many suppliers should I ask?
Three is the right number: one boutique, one mid market independent, one consultant. Five becomes administration, and one leaves you without a comparison.
What is a reasonable timeline to results?
A written diagnosis in month one, shipped technical fixes and pages inside the first quarter, and a readable trend over two to three quarters. Put those three checkpoints in the statement of work.
A common test for three bidders
A defensible procurement scores three proposals against one scope. Add a common test to that scope: have each bidder show what ChatGPT, Gemini and Perplexity return for your category, and what they would change. Same prompt, same date, same format.
The scoring then rests on evidence you can reproduce rather than on presentation quality. Leave your company name out of the prompt so the answer is not steered, and keep the output with the paperwork. AI Knows Us asks the assistants for you and lists the sources behind each answer, which suits a file that someone may review later.
