How it’s made

Every firm here was checked twice.

  1. 01
    Find

    Firms come from industry directories, business press, award lists and the client rosters of firms already known to do the work.

  2. 02
    Verify

    A firm's own site has to be live and describe the work. A second, independent source has to agree that it exists and does it.

  3. 03
    Record

    Leaders, addresses, founding years, awards and case studies are copied from a page we loaded, and each carries its link. A field stays blank until a source states it.

  4. 04
    Rank

    The order is editorial: longevity, named clients, scale and a clear specialism, in roughly that weight. Firms cannot buy a position.

  5. 05
    Re-check

    Every entry was re-checked on September 28, 2026, homepage captured, ownership confirmed. Firms that closed, stopped doing this work or changed hands are removed or noted in the change log below.

The featured card is paid placement for Fracs, which shares this list’s publisher. It sits outside the ranking. Read the full editorial standards, or write to lists@primortul.com with a correction or a firm we missed.

Asked, answered

Questions before you hire an SEO company in the US

How many SEO companies in the US are on this list, and where are they?
13. The 13 firms are spread across San Diego, San Francisco, Raleigh, New York, Syracuse, Simi Valley and 7 other cities. Each was checked against its own site and at least one independent source. Nobody pays to be ranked.
How do I choose between SEO companies in the US?
Write down what done looks like. Read why each firm is on the list and keep the two or three whose reason matches your job. Ask each for one piece of work like yours, and the name of the person who would do it. 1 of the 13 here are under 50 people, so the people you meet are usually the people who do the work.
Did any of these firms pay to be listed?
No. Nobody pays to be ranked. The order weighs how long a firm has done the work, clients it can name, its size, and how clear its specialism is. The one paid card is marked Featured. It sits outside the ranking. It is Fracs, which shares this list's publisher.
How long have these SEO companies been around?
The oldest firm on this list states 1995 as its founding year. A year is shown only when the firm states one.
What should I bring to a first call with an SEO company?
What you sell, what is not working, what done looks like, a budget range, and when you want to start. The form on this page asks for those. Asking is free. You do not have to hire anyone.
How is this list kept current?
Re-checked September 28, 2026. Dead sites come off. Mergers and renames are updated. Firms that belong are added. Send a correction to lists@primortul.com. If you are the firm, use the For partners form.

Describe the job. One SEO company writes back.

Tell us what you sell, what is not working, and what done looks like. We read it and ask one provider — from this list, or from the publisher’s bench — to contact you within a business day. Asking is free. You do not have to hire them. Nobody else gets what you wrote.

When

Sending shares what you wrote with the one provider we match you to. How that works.
