An SEO consulting firm sells judgement rather than hours: a diagnosis of why a site is not being found, a prioritised plan, and usually some supervision of whoever implements it. That is a genuinely useful purchase and also an easy one to fake, because the deliverable is advice and the results arrive months later. Google publishes its own guidance on hiring search help, and it reads as a buyer's checklist rather than a vendor's brochure. This page sets out what the work covers, which questions separate a consultancy from a reseller, and what a firm should be able to show you from its own published pages before a contract exists.
What a consulting firm actually delivers
A consulting engagement normally begins with an audit: how the site is crawled and indexed, which pages already earn impressions, which queries the business needs to own, and what is technically in the way. From there the deliverable is a ranked plan, not a task list. Google's own starter guide is blunt that creating content people find compelling and useful will likely influence a site's presence in search results more than any other suggestion it makes, so a plan weighted towards content and away from tricks is following the search engine rather than working around it. Some firms stop at the plan and hand it to your team; others keep a retainer to supervise delivery. Both are legitimate, but they are different purchases at different prices, and a proposal that does not say which one it is has left the most expensive question open.
The questions Google tells you to ask
Google's hiring page lists the interview questions directly. Ask for examples of previous work and success stories. Ask whether the firm follows Google Search Essentials. Ask what results it expects and in what timeframe, and how it measures success. Ask how it will communicate and whether it will share every change it makes to your site. The same page names the warning signs: firms that are secretive or will not clearly explain what they intend to do, unsolicited email pitches, claims of a special relationship with Google or priority submission, and link popularity schemes. It also states plainly that no one can guarantee a number one ranking on Google. During an audit, Google advises granting only read access to Search Console at that stage rather than write access, which is a reasonable line to hold with any firm you have not yet contracted.
Why guarantees are the fastest disqualifier
Google's own description of how Search works says it does not accept payment to crawl a site more frequently or rank it higher, and adds that if anyone tells you otherwise they are wrong. The same documentation says Google does not guarantee that it will crawl, index, or serve a page even when the page follows Search Essentials. A consulting firm that promises fixed positions by a fixed date is therefore promising something the search engine says is not for sale and not certain. The honest version of that conversation is a forecast with ranges, an explicit statement of what would have to be true for it to land, and reporting that shows impressions and query coverage moving before rankings do. Google's starter guide notes that some changes take effect in a few hours while others can take several months, which is the timeframe a serious firm will quote.
Testing a firm against its own published pages
Every claim a consultancy makes about itself is checkable before you call. Does it publish an address and a named team, or only a contact form. Does it print prices, or does every number arrive verbally. Do the case studies name the client and the metric, or describe an anonymous business in a vague vertical. Does the firm rank for its own specialty phrase, which is the one demonstration of competence it cannot outsource. For salary context on what senior marketing judgement costs to employ directly, the Bureau of Labor Statistics reports median pay for advertising, promotions and marketing managers of $159,660 per year in 2024, with employment projected to grow 6% from 2024 to 2034. A retainer that is a fraction of that for a genuinely senior consultant is worth asking hard questions about, because someone is doing the work at some price.
Questions people ask about seo consulting firm
What is the difference between an SEO consulting firm and an SEO agency?
A consultancy usually sells diagnosis, strategy and oversight while your team or a separate supplier executes. An agency usually sells execution on a retainer. Many firms do both, so ask which hours are advisory and which are delivery, and get that split written into the scope.
Can an SEO consulting firm guarantee rankings?
No. Google states that no one can guarantee a number one ranking, and its documentation says it does not guarantee it will crawl, index or serve a page at all. Treat a ranking guarantee as a reason to end the conversation rather than a reason to sign.
How long before a consulting engagement shows results?
Google's starter guide says some changes take effect in a few hours while others can take several months, and it suggests waiting several weeks before judging an individual change. Expect early movement in impressions and query coverage well before positions settle.
What access should I give during the audit?
Google advises granting only read access to Search Console at the audit stage rather than write access. Analytics read access and a copy of the site's crawl are usually enough; broader permissions can wait until a contract exists.
