Denver SEO companies, compared on the facts
Sixteen agencies that show up for Denver SEO searches, including us, laid out on the same eight questions. No scores, no paid placements, no "best of."
Every list of Denver SEO agencies you will find is either a directory that earns fees from placements or an agency ranking itself first. This page is different in one way only: every cell was read from the agency’s own site or its Clutch profile on October 19, 2026, and where an agency does not publish something we say so instead of guessing. We are in the table too, zeros included.
Direct answer: Denver SEO companies range from a six-person shop to a 160-person national agency with a Denver office. Of the sixteen compared here, six publish their SEO pricing, nine are headquartered in Denver itself, and Clutch review counts run from none to 147. Published monthly SEO prices in this group start at $500 (Eye To Ad Media) and $799 (Breakline) and run to $4,000 (BSM); most agencies quote privately. Use the table below to shortlist, then run the seven tests before you sign anything.
The lists that rank for “Denver SEO companies” are not comparisons. They are inventory.
Search the phrase and page one is Clutch, The Manifest, Built In, a Semrush partner list and two agencies ranking their own competitors. Clutch states on its Denver page that it “may earn a fee for some placements.” Agency-written lists put the author first. That is fine for them; it is not useful for you.
So we did the boring thing. We opened sixteen agency sites and their Clutch profiles on the same day and wrote down what each one actually says about itself: when it was founded, where it is really headquartered, what its reviews look like, whether it publishes a price, and whether its Denver page shows a client result with a number attached. Where a site blocked us or stayed silent, the cell says so. You can click every row and check.
One honesty note before the table. We sell Denver SEO. That is a reason to read our row as skeptically as any other, which is why it shows our empty Clutch profile next to everyone else’s.
Sixteen Denver SEO companies and agencies, same facts for each.
Sorted roughly by how often each appears for Denver SEO searches. “Clutch” is the rating and review count shown on the agency’s Clutch profile on October 19, 2026. “Case number” means a named client result with a figure, on the agency’s Denver page.
| Agency | Founded | Headquarters | Clutch | Published SEO pricing | Case number on Denver page |
|---|---|---|---|---|---|
| Thrive Internet Marketing Agency | 2005 | Arlington, Texas (Denver is one of 22 offices) | 4.6 from 112 reviews | Not published | Farah Law Firm, "+664%" organic traffic |

Founded years marked “(Clutch)” appear only on the Clutch profile; the agency’s own site did not state one. Intero Digital’s website returned an error to automated requests on the day we read it, so only its Clutch fields are shown. Breakline’s case study is on its home page because it has no Denver page.
Specialty, minimum project and team size

Four patterns worth knowing before you call anyone.
1. Ten of sixteen do not publish a price
Firestarter, Epidemic, BSM, Breakline, Blennd and we do. The other ten ask you to fill in a budget form first. That is not a red flag by itself, but it does mean the first call is a qualification call, not a quote. Published ranges in this group: $500 to $4,000 a month for ongoing SEO, with Blennd’s audits from $4,000 and Breakline’s plans from $799.
2. “Denver” is often a city page, not a home
Thrive is headquartered in Arlington, Texas. Breakline is in Guildford, England. Solid Digital is in Chicago. Intero Digital is in Colorado Springs. Each has a Denver office or a Denver page, and each may be excellent, but if local knowledge is part of what you are paying for, ask who in Denver will actually work on your account.
3. Review counts are not quality, but they are evidence
Intero (147), Thrive (112) and Solid Digital (41) have deep Clutch histories. Five agencies, including us, have a profile with no reviews at all. Clutch reviews are verified interviews, so a long history tells you clients kept coming back long enough to be asked. It tells you nothing about who answers your email.
4. Only six show a client number on the Denver page
Thrive, Firestarter, Webolutions, Volume Nine, BSM and Blennd put a named client and a figure on the page. Webolutions’ is the most specific: 155 monthly organic visits in March 2021 to 5,413 in December 2025. Ask any agency, including those six, how long the result took and what it cost, because a percentage without a timeline is a brochure.
Which Denver SEO companies to call, depending on what you are.
An honest shortlist includes people who are not us. These are starting points, not endorsements; run the tests on all of them.
A local service business with $500 to $3,000 a month
You want a Google Maps specialist who will publish a price and put a name on your account. Start with Firestarter SEO ($1,500 plans, six specialists), BSM ($2,000 plans, local-service focus), Epidemic Marketing (from $2,499) and us ($500 to $3,000, founder-led). Blennd’s Denver page quotes $1,000 to $5,000 a month as its local range.
A B2B or multi-location company with a bigger budget
Webolutions (founded 1994, $10,000 minimum), Volume Nine (5.0 from 33 Clutch reviews), Intero Digital (147 reviews, 200-plus staff per its own search listing) and Thrive (national scale with a Denver office) are built for that size. Expect a longer sales cycle and an account team rather than one person.
A business that mainly needs a new website first
Solid Digital (B2B sites), Webolutions (sites engineered for SEO) and Blennd (one team across design and search) lead with the build. If you want the site and the search campaign from the same hands in Denver, that is also what we do; see custom website design.
Our row, read the way you should read everyone’s.
Eye To Ad Media was founded in Denver in 2012 and is run by its founder with a small team he trained. We publish our prices ($500 to $3,000 a month for most Denver campaigns, $100 build-your-own, $79.99 VIP), we hold 60 Google reviews at 5.0, and the BBB lists our parent company, Search Converts LLC, as A+ accredited. Our proof is unusual in this group: the businesses we rank are partly our own, so you can search the terms yourself today rather than trust a screenshot. The case studies page tells you which terms.
What our row does not show: a Clutch review history (the profile exists and is empty, and the “$5,000+” minimum on it is stale), a large team, or a national footprint of offices. If you want those, several agencies above have them. If you want the person who sold you to be the person who builds it, that is the specific thing we offer, and the agency page explains how the work is organized.
Whoever you shortlist, the next step is the same: put them through the seven tests, ask the nine questions, and compare the answers in writing.
About this comparison of Denver SEO companies.
They are the agencies that appeared most often in Google results for "denver seo company," "denver seo agency," "denver seo companies" and "denver seo" on October 19, 2026, plus the three businesses shown in Google’s Denver local pack for "denver seo company" that day, plus us. Nobody paid to be included and nobody can pay to be removed.
Because the agency’s own website did not state it on the pages we read. We did not fill gaps from third-party estimates. If an agency publishes the figure later, the cell is wrong until we update it, which is why the read date is on the page.
It is evidence of a longer client history on one platform, not a quality score. Several good Denver agencies have no Clutch reviews, including us. Read a few of the actual reviews for the agencies you shortlist; the text is more useful than the count.
Among the six agencies here that publish prices, ongoing SEO runs from $500 to $4,000 a month, with audits priced separately by some (Blennd from $4,000). Agencies that do not publish prices generally quote after a budget form; Clutch minimum project sizes in this group are $1,000 to $10,000. Our own ranges are on the Denver SEO pricing page.
Yes, when we re-read the sources. The date at the top is the read date for every figure. If you run one of these agencies and a fact is wrong, call the number in the header and we will check it and correct it.
