Best SEO providers and SEO service providers compared, ranked on what each firm publishes that you can check

"SEO provider" is a shopping word, not a product. Four different kinds of supplier rank for it, they charge in four different ways, and the one you should buy depends on a number you already know: your monthly budget and whether anyone in your business will own the work.

This page sorts the four, gives one ranking criterion that a buyer can verify without a sales call, and names what each firm actually published on its own site on 21 October 2026.

The four kinds of SEO provider, and who each one suits

The full service digital agency. SEO is one line inside a retainer that also carries paid media, creative and a website. WebFX publishes its model openly at webfx.com/seo/pricing, read on 21 October 2026: "SEO costs an average of $1,000 to $5,000 per month for monthly retainers, $75 to $200 per hour for consulting, and $500 to $5,000 per project", with "most businesses spend $2,500 per month". The same page carries a points based scoping rubric, where market location scores one to four points and market competition scores niche through global, so a buyer can see how the number was built rather than being handed it.

The trade specialist. One industry, a repeatable page inventory, and a published rate card. Hook Agency, read at hookagency.com/pricing on 21 October 2026, serves home services from a 30 person team and prices local SEO from $2,800 a month, with answer engine work sold as its own line at $4,000 a month or $2,000 when added to an SEO package. That second line is the interesting one and we come back to it.

The independent consultant. One person, usually ex agency, priced by the hour or by the project. Cheaper per hour than an agency and capacity limited.

The software vendor sold as a provider. Moz, Semrush, Ahrefs and SE Ranking supply the data and the audit, and you or somebody you hire does the work. Moz lists its entry tier at "$45/month" and its large scale SEO and GEO product from "$360 / month" on moz.com/products, read 21 October 2026.

The ranking criterion, applied to everybody including us

The criterion is this: how much of the offer does the firm publish on its own website, where a buyer can read it before the first call? Not awards, not logos, not case study percentages. The price model, the deliverable list, and the limit that sets each tier.

On that criterion the order on 21 October 2026 ran: WebFX first, because it publishes both the rate ranges and the scoring rubric that produces a quote. Hook Agency second, because it publishes a per service monthly rate and says which figures are starting prices. Moz and the other software vendors third, because the plan limits are published but the work is not included. The large national agencies last, because several publish nothing checkable at all. scorpion.co returned HTTP 403 to our request on 21 October 2026, so we verified nothing about it and claim nothing about it here. A 403 is a blocked fetch rather than evidence about the company.

Two warnings that come from Google rather than from us

Google's own SEO starter guide, at developers.google.com/search/docs/fundamentals/seo-starter-guide and stamped "Last updated 2025-12-10 UTC" when we read it on 21 October 2026, says plainly that for most sites "you usually don't need to do anything except publish your site on the web", and then points readers who are short on time towards hiring a professional. That is a useful calibration: a provider whose first proposal is a rebuild of everything is proposing more than the documentation asks for.

The second warning is older and still the most reliable filter on this market. Be wary of any provider that offers a promise about a position number. Nobody controls the ranking system, and a firm that claims to is telling you something about its sales process.

The question none of these four is measuring, and what we actually sell

Here is the gap we care about, and we are not an SEO provider, so read this as a different purchase rather than a fifth option on the list above. Every firm above sells position in a list of links. A growing share of buyers now reads an answer instead of a list, and the question that decides whether you are in it is not where you rank. It is whether ChatGPT, Gemini, Perplexity, Claude or Google AI Overviews names your business when somebody asks who to buy from, without naming you in the question.

Hook Agency's rate card is the evidence that this has already become a separate purchase: it sells answer engine work as its own $4,000 a month line, next to SEO. What that line does not include is the measurement of whether it worked. AI Knows Us is the measurement. We check those five surfaces, report who was named instead of you, and run the content and placement work to change it. A credit is one buyer question put to one app once. A Claude check costs three credits because the Anthropic API with live web search is the expensive one; most checks cost one.

Our own ladder is published in full at aiknowsus.com/llms.txt, which is served as plain text, so a crawler reads it without running any JavaScript. Read on 21 October 2026 it carries eight self serve plans with the limit that sets each one: SEO Start $149 a month with no buyer questions watched and a monthly demand harvest, Growth $299 with 100 buyer questions watched, 1,200 scheduled answers a month and five engines, SEO Scale $699, Scale $599 with 300 questions and 3,500 scheduled answers, Inbound $1,099 with 200 questions, Outbound $1,299 with 30 questions and four engines, Agency $1,299 with 80 questions and 12,300 credits, and Everything $1,799 with 300 questions and 3,600 scheduled answers. A top up of 1,000 credits is $49. $149 is the published United States floor. Managed GEO is listed at Rs 88,499 to Rs 2,35,999 a month with a three month minimum and is published in rupees only, so we quote it in rupees rather than converting it ourselves.

One thing this page said about our own site was wrong, and a buyer would have hit it, so it is corrected here, dated 21 October 2026. The dollar prices are not added in the browser: a crawler request that day returned the dollar ladder and the rupee ladder in the same server response, 24 dollar figures and 31 rupee figures. The dollar figures above come from the plain text file, which is the server rendered source.

Two rules sit behind every number we publish, and both are on the methodology page. The buyer question never names the business being measured, because a question that contains the brand name produces an answer that contains the brand name. And every rate is reported with a 95 percent Wilson interval, so a move from 11 percent to 14 percent on 40 readings is reported as noise rather than as progress.

Where rivals are ahead of us on this criterion, here it is. Ahrefs Brand Radar, read on ahrefs.com/brand-radar on 21 October 2026, names seven surfaces against our five: ChatGPT, AI Overviews, AI Mode, Gemini, Perplexity, Copilot and Claude. It also publishes its own per engine cost in plain language, "Claude consumes 8 checks per update", and an overage rate of $0.020 a check, which is more disclosure of unit economics than we publish. Profound publishes "Up to 9 Answer Engines tracked" and "SSO/SAML + SOC 2 compliance" on its enterprise tier at tryprofound.com/pricing, read the same day. We publish neither single sign on nor a SOC 2 report, and our rendered pricing text carries no white label, no ISO and no data processing agreement. Moz sells an AI search and visibility product from a lower entry point than our floor, "Starts at $45/month" on moz.com/products, read the same day.

On the one criterion this page uses, publishing the offer where a buyer can check it, we put ourselves first among the measurement vendors, and the check is specific: of the vendors read on 21 October 2026, ours was the only price and tier limit set readable in a server rendered plain text file in three currencies. Peec AI publishes plan limits such as "50 prompts" and "Choose 3 models" at peec.ai/pricing but no price rendered in the first response. Profound and Similarweb publish no self serve price at all. Rankscale renders every numeric cell of its comparison matrix as 0, so a scrape of that table reports a product with no limits.

How to choose between the four in one sitting

Under $2,000 a month, buy a consultant or software plus your own time. Between $2,000 and $6,000, buy the trade specialist if your industry has one, because the page inventory is already built. Above $6,000 with several channels, buy the full service agency and argue about the fee model rather than the headline number. At every level, ask for the answer engine question to be named in the scope in writing, because a retainer that does not mention it will not report on it.

If you want the shortlist for one country rather than the four categories, we keep a separate page on how to rank a United States SEO shortlist on what each firm publishes. No other page on this site links to that one, measured across the 2,017 of 2,082 live pages whose text we can read, on 21 October 2026.

What buyers ask about choosing an SEO provider

Is a bigger agency safer? It is more insulated against one person leaving and less likely to publish its prices. Both of those matter, and the trade off is yours.

Should SEO and answer engine work sit with the same supplier? They can, and the reporting should not. The firm doing the work is the wrong party to grade it, which is the whole reason the measurement is a separate purchase.

What is the shortest contract worth signing? Three months buys an audit and a first wave of pages. Six is the first point at which organic movement is readable. Anything asking for twelve before the first deliverable is asking you to fund the learning curve.
