SEO consultants sell judgment rather than deliverables, which makes them the hardest marketing hire to evaluate: there is no portfolio page that proves a recommendation was right. The compensating advantage is that Google publishes its own vetting guidance for exactly this purchase, and it is specific enough to run an interview from. This page turns that guidance into a working process: what to ask, what a consultant should ask you, how to think about cost, and which claims end the conversation.
Run the interview Google wrote
Google's documentation for site owners hiring an SEO reads as a question list. Ask for examples of past work and success stories you can verify. Ask whether they follow Google's Search Essentials, and how they will explain every change they recommend and the reasoning behind it. Ask what results they expect in what timeframe and how success will be measured; the documentation is explicit that no one can guarantee a #1 ranking, so the realistic answer describes a process, not a position. Ask about experience in your industry and your geography. And watch what they ask you: Google's guidance says a good SEO wants to know about your business, your competitors and your customers, because recommendations made without that context are templates.
What consultants cost, anchored to something real
Consulting rates float free of any published index, but the labour market underneath them does not. The Bureau of Labor Statistics puts median pay for marketing managers at $161,030 a year as of 2024, with 434,000 people employed across advertising, promotions and marketing management, growing 6% over the decade to 2034. That is the salary a capable in-house owner of this work commands, and it is the honest comparator for a consulting retainer: a consultant charging a meaningful fraction of that salary should be delivering a meaningful fraction of that role's output, with the flexibility and senior focus that justify the premium over hiring. Anchoring to the salary line also exposes the low end; deeply discounted retainers usually price in templated work.
Disqualifiers and working terms
Google lists the red flags by name: guaranteed rankings, claimed special relationships with Google, priority submission offers, unsolicited pitches, and secrecy about methods. Add contractual hygiene. At the audit stage, grant read-only access to Search Console, which Google's guidance itself advises; write access and site access come only with an engagement. Insist that every recommendation arrives with its reasoning, so the work transfers knowledge instead of creating dependency. Set the measurement plan before the work starts, with Google's own timeline honesty built in: its starter guide says changes can take from hours to several months to show effects, so early reports should track leading indicators like indexation and impressions rather than promising ranking jumps.
Questions people ask about seo consultants
What is the difference between an SEO consultant and an agency?
A consultant sells senior judgment, usually advisory, with execution left to your team; an agency sells execution capacity with judgment spread across a team. Small sites with in-house developers often get more from a consultant; teams with no hands to implement need an agency or both.
How much do SEO consultants charge?
Rates vary too widely for a single figure, and few consultants publish them. A useful anchor is the in-house alternative: BLS reports median marketing-manager pay of $161,030 as of 2024. Price a retainer as a fraction of that role and demand a corresponding fraction of senior output.
What guarantees can an SEO consultant legitimately offer?
Process guarantees only: what will be analysed, what will be recommended, how changes will be explained, and how results will be measured. Google's documentation states no one can guarantee a #1 ranking; a consultant who offers one is disqualified by the platform's own standard.
What access should I give a consultant at the start?
Read-only access to Search Console and analytics for the initial audit, which is the level Google's hiring guidance recommends. Broader access, to the CMS or the codebase, comes after an engagement exists and only to the extent the agreed work requires.
