Best white hat SEO services compared, and the four contract clauses that make a method checkable

No supplier describes itself as anything else, so the phrase carries no information on its own. What carries information is whether the contract lets you check. These four clauses do, and a supplier that will sign all four is telling you something a sales call cannot.

The four clauses

One. A link disclosure clause. Every link acquired on your behalf is reported monthly with the placing URL, the date and the method: editorial outreach, digital public relations, a directory, a paid placement, a guest contribution. The clause matters because paid links that pass ranking signals are against the published guidelines of the search engine you are trying to rank in, and you are the party that carries the consequence rather than your supplier. A supplier doing clean work has this list anyway. A supplier that cannot produce it does not know what it bought on your behalf.

Two. A content provenance clause. Who wrote each page, whether a generative model was involved and to what extent, and whether anything was published under a byline belonging to a person who did not write it. The last of those is the one that creates a real problem later, and it is the one nobody asks about.

Three. An access and ownership clause. Analytics, Search Console, the content management system and the domain registrar all in your name, with the supplier added as a user. If your supplier holds the only administrative access to your own property, every other clause is unenforceable.

Four. A remediation clause. If a tactic used on your site is later found to breach the published guidelines, who removes it and who pays. Without this, the cost of cleaning up a previous supplier work lands entirely on you, and cleanup is routinely more expensive than the original work.

Three questions that separate method from vocabulary

What have you refused to do for a client, and why. A supplier with a real line has an example. The answer is usually about a link scheme, a reviews shortcut or a doorway page.

Show me a link you placed last month and tell me how. One live example with a method attached. Vague answers here are the single most reliable warning sign in this category.

What would you do if we fell out of the index tomorrow. The useful answer starts with reading the manual actions report rather than with a theory.

Ranked on one criterion, applied to everybody including us

The criterion is whether the supplier publishes its method in enough detail to be checked against it. Read on 21 October 2026:

First, Ahrefs, at ahrefs.com/brand-radar, which publishes both how its measurement is built and what each unit costs: "Claude consumes 8 checks per update", "$0.020/check billed monthly", and an index broken out as AI Overviews 277,456,152, AI Mode 100,797,074, Gemini 28,930,170, Copilot 28,921,226 and Perplexity 28,837,146 against a stated 493 million monthly prompts. Its page also describes those prompts two different ways, as "493 million real prompts people ask AI platforms" and as "modeled from real user searches in Ahrefs keyword database", and a careful buyer should read both lines rather than one.

Second, Moz, at moz.com/products, which publishes three products, three prices and a named capability list for each: "Starts at $99 / month", "Starts at $45/month", "Starts at $16 / month".

The white hat SEO service providers are unranked, because of those read on 21 October 2026 none published a link disclosure policy, a content provenance statement or a remediation position. The whole category markets on a word and documents none of the practice behind it, which is why this page is about the contract instead.

A method you can check from outside, which is the whole product

Somebody in your market is asking an assistant who they should use and getting two or three company names back. We counted which names, in our own audit of 1,872 assistant readings, in which a vendor is counted once per reading whose answer names it in the prose. WebFX was named in 26 readings, 23 of them in the United States, 2 in the United Kingdom and 1 in India. Percepture was named in 11, all United States. Rank4AI was named in 20, all United Kingdom. Whito was named in 2 readings. Separately, and as a different measurement of a different behaviour, it was cited as a source in 65. A citation is an engine using a page. A naming is an engine recommending a company. This page keeps those two numbers apart and never adds them.

We are not an SEO supplier and we do not place links. AI Knows Us sits beside search as a separate measurement, and the reason it belongs on a page about checkable method is that our method is the product rather than a reassurance. The real ChatGPT and Gemini apps are read through a third party data provider, Perplexity through the official Agent API, Claude through the official Anthropic API with live web search, and Google AI Overviews through a licensed search results provider. The buyer question never names the business being measured. Every rate is reported with a 95 percent Wilson interval, so a move from 11 percent to 14 percent on forty readings is called noise. All of that is published, which is exactly the standard this page asks of an SEO supplier.

Our own ladder is published as plain text at aiknowsus.com/llms.txt, which a crawler reads without running any JavaScript, and rendered in six currencies at aiknowsus.com/pricing. Read on 21 October 2026, SEO Start is $149, Growth $299, SEO Scale $699, Scale $599, Inbound $1,099, Outbound $1,299, Agency $1,299 and Everything $1,799 a month, with 1,000 extra credits at $49. The limits are the part worth reading. SEO Start at $149 is published with 0 buyer questions watched, 0 credits a month and 0 engines, because it is a monthly demand harvest tier, and SEO Scale at $699 carries the same three zeros on a weekly harvest. Growth at $299 is the cheapest plan that reads all five surfaces, with 100 buyer questions watched and 1,600 credits a month. Managed GEO is published in rupees only, Rs 88,499 to Rs 2,35,999 a month with a three month minimum, so we quote it in rupees rather than converting it ourselves.

Where rivals beat us on this page criterion, here it is, read on 21 October 2026. Ahrefs Brand Radar, at ahrefs.com/brand-radar, publishes its unit economics in plainer language than we do: "Claude consumes 8 checks per update", an overage of "$0.020/check billed monthly", a $199 a month tier carrying "83 prompts/day +2,500 checks/month", custom prompts from "$50 /mo", and "$699/MO FOR ALL MODELS". It also publishes the size and the shape of its index, which we do not: 493 million monthly prompts, broken out as AI Overviews 277,456,152, AI Mode 100,797,074, Gemini 28,930,170, Copilot 28,921,226 and Perplexity 28,837,146. Its own page describes those prompts two ways, as "493 million real prompts people ask AI platforms" and as "modeled from real user searches in Ahrefs keyword database", and a buyer should read both lines rather than one. Moz, at moz.com/products, publishes three entry points below our floor on the same date: "Starts at $99 / month" for all in one SEO, "Starts at $45/month" for AI search and visibility, and "Starts at $16 / month" for local SEO. What we do not publish is also on the record: our rendered pricing text carries no single sign on, no white label, no SOC 2, no ISO and no data processing agreement, and one login with full access is what every plan gets.

Where we come first: on publishing a method in enough detail to be checked, we publish the data path for each of the five surfaces, the rule about brand names in questions and the statistical test, alongside every tier price and allowance. Ahrefs publishes a fuller account of its own index and its cost per check, and Moz prices three products below our cheapest five surface tier.

If the specific worry is links, the automated tools in that market have already been tested against the search engine own published position in automated link building tools compared against the published policy. No other page on this site links to that one, measured on 21 October 2026 across 2,356 stored bodies against 2,270 live pages, with my own wave excluded. 948 of those 2,270 pages, 41.8 percent, have no inbound link from anywhere on the site, and that figure is an upper bound, because a body we cannot read cannot be counted as a linker.
