What a Generative Engine Optimization Agency Costs in Practice

Three Tiers, Three Very Different Products

Most buyers walk in expecting one thing: a retainer that makes them show up in ChatGPT or Perplexity answers. What they are actually shopping for is a spectrum of three different products bundled under one label. The first is a diagnostic, a one-time audit of how AI search engines currently reference your business versus five to eight named competitors. You get a report, a gap list, and a prioritized fix sheet. It costs between $2,800 and $4,500 depending on how many service lines or locations you need mapped. You will never see my name attached to it if you do not hire the next two tiers, and that is fair.

The second tier is implementation. This is where someone restructures your entity data, rewrites the pages AI engines pull from, builds out citation sources in directories and local knowledge panels, and adjusts how your content answers the specific question patterns that show up in generated responses. At SEMPITE this runs $5,200 to $8,000 per month for a small business with one to three locations. It is hands-on editing work, not dashboard monitoring, and it typically takes six to ten weeks before I can say the changes are reflected consistently across the major AI answer surfaces.

The third tier is ongoing optimization and competitive defense. This is a $9,500 to $14,000 monthly retainer that layers continuous visibility tracking, quarterly content strategy refreshes, and reactive updates when an algorithm shift or a competitor content push changes how you are cited. I want to be blunt: if your business does not generate enough revenue per customer to justify a five-figure monthly line item, this tier is the wrong fit, and any agency that tells you otherwise is selling a product they do not need to defend at renewal.

What the Cheapest Tier Actually Buys You

I have watched clients sign a $2,500 monthly 'GEO package' from a larger firm and receive a PDF with 40 bullet points about E-E-A-T signals. That report is not wrong. It is also not specific to their business, their market, or the actual question strings that surface in AI-generated answers for their category. The trade-off is clear: you are paying for general SEO hygiene rebranded under a newer term, and the agency will point to a 12 percent lift in organic impressions at month three as proof of GEO work. Those are two different measurement problems, and conflating them saves the agency from doing the harder one.

What I do instead at the diagnostic tier is pull 200 to 300 real query strings that people type into AI assistants for your service category, run them through the major answer engines, and log exactly where you appear, how you are described, and which competitor gets cited in your place. That log becomes the gap list. It is unglamorous work. It takes me roughly nine to eleven focused days per client because I am reading generated answers by hand, not scraping a dashboard. The deliverable is a 30 to 50 page document with specific page-level recommendations, not a slide deck.

The uncomfortable truth is that for many small businesses the diagnostic reveals a problem GEO cannot solve. If your content is thin, if you have no distinct service differentiation, or if your local entity data is contradictory across sources, no amount of optimization will make an AI engine cite you over a competitor with a cleaner information footprint. I tell clients this in the first call, and roughly one in five do not proceed past the audit. That is a good outcome for them, even though it means a smaller check for me.

Where the Ongoing Retainer Money Goes

Clients assume the $9,500 to $14,000 monthly tier is mostly software licenses and API calls. It is not. The bulk of that fee is my time and the time of one other editor who works with me on content restructuring. We are rewriting 12 to 20 pages per month in a way that AI engines can parse cleanly: clear entity definitions, unambiguous service descriptions, FAQ blocks that mirror real user phrasing, and internal linking that gives an answer engine a logical path through your site rather than a maze. That is editorial labor, not automation.

The tracking layer costs less than people think. I monitor how often your business name and service terms appear in generated answers across the major AI platforms, logged weekly against a competitor set of five to eight names. I can tell you that citation frequency for one plumbing client went from appearing in roughly 8 percent of relevant generated answers at week zero to about 34 percent by week nine. I will not call that a proven causal link to revenue, because I do not have their close-rate data, but the visibility shift is measurable and repeatable.

What the retainer does not cover is paid advertising, video production, or social media management. If an agency quotes you a GEO package that includes all of those, you are paying for a generalist digital marketing firm with a GEO line item bolted on. The trade-off is that your GEO work gets 20 percent of the attention in a $15,000 account instead of 80 percent of the attention in a focused $9,500 one. For a small business whose primary discovery channel has shifted to AI-generated answers, that concentration matters more than breadth.

What GEO Cannot Fix for You

I will name the limits plainly because I have lost two clients who expected a different result. First, if your business model is so generic that an AI engine has no reason to distinguish you from forty similar providers in the same zip code, optimization will widen your visibility margin but will not create a moat. You need a specific angle, a named methodology, a distinct service package, something an answer engine can point to and say this one is different. I will flag that gap in the diagnostic and I will not pretend content tweaks will manufacture differentiation.

Second, AI search engines update their citation logic on schedules I do not control. A change that lifted your visibility in March can be partially reversed by a model update in June. This is not a failure of the optimization work; it is a property of the medium. Any agency that guarantees sustained position or promises you will be the number-one cited result for a given query is selling something I would not sign off on myself. What I can commit to is that we detect shifts within a week and respond with structural updates, but the baseline is moving.

Third, and this one stings because it is partially my fault: the industry has no standardized measurement protocol yet. There is no MozBar equivalent for AI answer citation frequency, no universally accepted way to say I am visible in 40 percent of relevant generated responses that another firm will independently verify. I track this rigorously, but I cannot hand you a third-party audit that says my numbers are correct. You are trusting the methodology of the person doing the work, and that is a real risk factor in your vendor comparison.

The One Question to Ask Before You Sign

Before you commit to any GEO agency, ask them this: show me the exact query strings you tested for my specific service category in my specific metro area, and tell me which competitor currently gets cited in place of me for each one. Not a demo on their laptop with a generic search term. The actual log from a client in your vertical, redacted for name if you must, but showing the question, the generated answer, the citation slot, and where my category of business appears or does not appear. If they cannot produce that artifact in under ten minutes, they are not doing the work they are selling.

You do not need to take my word for any of this pricing. The numbers I have given you are mine, from my own books, for my own capacity constraints. A firm with a team of twelve will quote differently because their cost structure is different, and that is legitimate. What should not be different is the specificity of what they show you before you sign. Vague promises about AI visibility in 2025 are the new we will improve your organic ranking from 2019, and it means the same thing: they have not yet looked at your actual problem.

Get the diagnostic first. Read the gap list against your own knowledge of what customers actually search for. If the recommendations match what you already suspected, you can evaluate the implementation tier on price and process. If the report is generic enough to apply to any business in any city, walk away and save the $3,000. You know your market better than a sales deck does, and that instinct is worth more than any agency's slide about generative engine optimization.
