“No one can guarantee a #1 ranking on Google.” That is Google’s own sentence, on its own page about hiring a search provider, still live and updated in June 2026.
The same page publishes eight questions to ask, a list of warning signs, and advice on what access to hand over. It is the single most useful document on this subject, it is free, and almost nobody buying these services has read it.
This page sets out what it says, then what US advertising doctrine adds, which turns a ranking guarantee from an implausible promise into an exposed one.
The eight questions, verbatim
Google publishes these as the questions to ask before engaging a provider. They are worth using unedited.
On evidence. Can you show me examples of your previous work and share some success stories?
On method. Do you follow the Google Search Essentials, previously known as Webmaster Guidelines?
On expectations. What kind of results do you expect to see, and in what timeframe? How do you measure your success?
On sector. What is your experience in my industry?
On geography. What is your experience in my country or city?
On international work. What is your experience developing international sites?
On the firm. How long have you been in business?
On working practice. How can I expect to communicate with you? Will you share with me all the changes you make to my site, and provide detailed information about your recommendations and the reasoning behind them?
Two additional checks Google recommends. Check the provider’s business references, asking past clients whether the service was useful, easy to work with and produced positive results. And evaluate the recommendations and tools: specifically, whether they cite official Google documentation as supporting evidence for their recommendations, and whether their tools are aligned with Google’s guidance.
Why that last one is the strongest filter in the list. It is checkable in a first meeting, it costs nothing, and it separates practitioners who work from documentation from those working from convention. Ask for the citation behind any recommendation.
The warning signs Google lists
A short, specific list, and each item names an actual practice.
Unsolicited email. Google’s own comparison: reserve the same scepticism for unsolicited email about search engines as you do for “burn fat at night” diet pills or requests to help transfer funds from deposed dictators.
Secrecy. Be careful if a company is secretive or will not clearly explain what they intend to do.
The risk it creates. If a provider creates deceptive or misleading content on your behalf, your site could be removed entirely from Google’s index.
A specific practice to refuse. You should never have to link to an SEO.
Two obsolete offers. Avoid providers that talk about link popularity schemes or submitting your site to thousands of search engines, described as typically useless exercises that do not affect your ranking.
Tool claims. Be wary of tools that claim to be acceptable or approved by Google Search.
And the one that ends a sales conversation. If they guarantee you that their changes will give you first place in search results, find someone else.
This is where the subject stops being about credibility and starts being about doctrine.
The US requirement, verbatim. That advertisers and ad agencies have a reasonable basis for advertising claims before they are disseminated.
What failing that means, verbatim. That a firm’s failure to possess and rely upon a reasonable basis for objective claims constitutes an unfair and deceptive act or practice in violation of Section 5 of the Federal Trade Commission Act.
And the enforcement position, verbatim. That as a matter of law, firms lacking a reasonable basis before an ad is disseminated violate Section 5 and are subject to prosecution.
Why a ranking guarantee cannot meet that standard. The outcome depends on an algorithm the provider does not operate, whose behaviour is not disclosed, and which changes without notice. There is no basis available to be reasonable about.
The regulator has acted in this territory. A 2018 case against operators who used robocalls to falsely claim to represent Google, falsely threatened businesses with removal from Google, and promised top placement for fees. The regulator’s own summary states that the defendants falsely promise that by joining the Citation Program, the business will become the first search result or one of the top results.
And its general statement in that context. That no robocaller can make any promise or guarantee that they can get your business a top search result or preferred placement on an online map.
One honest limit on this. I could not find a case against a conventional B2B agency selling monthly retainers with ranking promises. The documented actions involve robocalls and impersonation. The doctrine applies more broadly than the caselaw demonstrates, and that distinction belongs in any use of this argument.
What does not apply, said plainly
Worth stating because these rules get invoked loosely.
Business opportunity rules. They cover a seller soliciting someone to enter a new business, where the buyer makes a required payment, and the seller promises to provide locations, outlets, accounts or customers, or to buy back goods.
Why a normal SEO retainer is not that. An operating company buying a marketing service is not entering a new business, and the provider is not promising to supply it with outlets or customers in the sense the rule means.
When it could apply. If an offer is packaged as a turnkey money-making opportunity, with revenue promises attached, the framing rather than the label determines the classification.
The general point. Do not reach for a rule that does not fit. The substantiation doctrine above is sufficient and it actually applies.
Two practical items, one of which has a widely quoted figure that is not where people think it is.
On access, verbatim. If a provider offers to do an audit, consider carefully what is involved and only grant read access to Search Console; at this stage, do not grant write access.
On server access, verbatim. If a provider has FTP access to your server, they should be willing to explain all the changes they are making to your site.
What that gives you as a rule. Read access for diagnosis. Write access only once you have seen the recommendations and agreed them, and never without a record of what changed.
On timeframe, what the guidance page actually says. Nothing. There is no figure for how long results take on that page.
The figure everyone cites. Four months to a year. It comes from a 2017 Google video presentation on hiring an SEO, not from current documentation.
How to use it honestly. As a 2017 statement from a Google representative, still widely repeated, rather than as current policy. It remains a reasonable planning assumption; it is not a citation you can point to in the documentation.
What the starter guide does say. That some changes might take effect in a few hours and others could take several months, and that you likely want to wait a few weeks to assess whether work had beneficial effects. Vaguer, and current.
The structural question underneath the choice, which the documentation does not address and which matters.
What an agency gives you. Coverage across specialisms, continuity when someone leaves, and a contractual counterparty with something to lose. You pay for the overhead that produces those.
What it costs you. Distance from the person doing the work, and a real risk that the seniority you met is not the seniority you get.
What a consultant gives you. The person you met is the person working, with direct accountability and usually more strategic range for the money.
What it costs you. Capacity limits, a single point of failure, and no coverage when they are unavailable.
What a freelancer gives you. Execution on a defined scope, at the lowest cost per hour.
What it costs you. You supply the direction. A freelancer executing an unclear brief produces unclear work, and that is a client failure rather than a supplier one.
The question that actually decides it. Do you know what needs doing? If yes, buy execution. If no, buy diagnosis first, from whoever can cite documentation for their reasoning, and decide the delivery model afterwards.
Google publishes eight questions to ask a provider, plus reference checks and a test of whether they cite documentation.
The guarantee sentence is categorical: no one can guarantee a number one ranking, and beware of claims of a special relationship or priority submission.
The warning list is specific: unsolicited email, secrecy, link schemes, mass submission, tools claiming Google approval, and any first-place guarantee.
On access: read-only Search Console at the audit stage, explicitly not write access.
There is no timeframe figure on that page. The four months to a year figure is from a 2017 video, not current documentation.
US doctrine requires a reasonable basis for a claim before making it, and failing that is an unfair and deceptive practice under Section 5.
A ranking guarantee cannot meet that standard, because the outcome depends on an algorithm the provider does not operate.
The regulator has acted on top-placement promises, though the documented cases involve robocalls and impersonation rather than conventional retainers.
Yes, a dedicated page with eight suggested questions, a list of warning signs, guidance on what access to grant, and an explicit statement about ranking guarantees. It is the most useful document in this subject and almost nobody reads it.
What does Google say about ranking guarantees?
Verbatim: no one can guarantee a number one ranking on Google, and beware of providers that claim to guarantee rankings, allege a special relationship with Google, or advertise a priority submit to Google.
What access should I give a provider?
Google advises granting only read access to Search Console at the audit stage, explicitly not write access. If they have server access, it says they should be willing to explain every change they make.
How long should SEO take to work?
The current guidance page gives no figure. The four months to a year figure that circulates comes from a 2017 Google video, not from the documentation, so cite it as a 2017 statement rather than as current policy.
Is a ranking guarantee illegal in the US?
Not automatically, but it is exposed. US doctrine requires a reasonable basis for a claim before it is made, and a provider cannot have a reasonable basis for an outcome controlled by an algorithm it does not operate.
Has the FTC acted on this?
Yes, against a 2018 scheme that used robocalls to falsely claim Google affiliation and promise top placement. In that context the FTC stated that no robocaller can promise or guarantee a top search result.
Do business opportunity rules apply to SEO contracts?
Generally no. Those rules cover selling someone a new business with required payment and promised outlets or customers. A retainer sold to an operating company is not that, unless it is dressed up as a turnkey money-making opportunity.
What is the single best filter?
Ask them to cite official documentation for their recommendations. Google itself suggests evaluating whether a provider cites its documentation as supporting evidence. Providers who cannot will usually stop returning calls.
