Generative Engine Optimization Services: What They Include and What None Can Promise

Key takeaways

The short version of this page, in the order the sections below develop it. Each point is stated here in full so it can be read without the rest of the page, and the section that argues it gives the measurement and the source behind it.

• The work on three providers' service pages sorts into five groups: an audit of current AI answers, on-site content, technical work, off-site sources and ongoing reporting.
• Google's guidance on third-party services says using a service or tool "doesn't guarantee ranking success", and its AI guide says no third-party tool has access to its internal ranking or AI systems.
• UPAI's landing page lists work in three of the five groups: the hand-run check, the off-site sources and the weekly re-measurement. It lists no on-site content and no technical work.
• Ask for evidence per group: dated raw answers for the audit, the changed pages for content, a dated change list for technical work, a link to every listing, and dated readings from each re-run.

What do generative engine optimization services actually include?

Generative engine optimization services are paid work aimed at getting a company named or cited in AI-generated answers, and the work sorts into five groups: an audit of current answers, on-site content, technical work, off-site sources and ongoing reporting. Providers' pages do not list the same work, so read the deliverable list, not the label.

The five groups, as we define them:

• Audit of current answers. Asking AI assistants your buyers' questions and recording which companies are named and which sources are cited.
• On-site content. New or rewritten pages on your own site.
• Technical work. Crawl access, indexing, markup and site structure.
• Off-site sources. Getting the company listed, reviewed or described correctly on sites it does not own.
• Ongoing reporting. The same measurement repeated, so a change can be dated.

Google's guide to generative AI features describes AEO and GEO as "terms you may see used to describe work specifically focused on improving visibility in AI search experiences."

What do three providers list on their own GEO services pages?

The three pages list overlapping but different work: First Page Sage lists six elements, among them list articles, databases and reviews, while Omniscient Digital and Optimist both list an analysis or audit and ongoing tracking. We chose these three because each page lists its deliverables explicitly enough to put in a table. It is not a ranking.

First Page Sage frames its service as "6 key elements" and says its team acts as "content creator, list & database outreach manager, and online reputation monitor". Two of the six sit outside our rows: "Website Authority", which the page describes as high rankings on Google and Bing, and "Achievement Publicization".

Optimist also publishes a ranking of GEO agencies, and its first entry is Optimist, as "Best GEO & SEO Agency for B2B SaaS"; the page notes this itself. We cite it only for Optimist's prices.

What do these pages say about price?

Omniscient Digital's service page states a starting price in the contact block at its foot: "Full-service engagements start at $10,000 a month." The sentence is not specific to GEO work. It is one agency's published figure on October 5, 2026, not a market rate. Optimist's service page states none, but the entry for Optimist in its own agency ranking gives: "a one-time roadmap from $7,500, with month-to-month retainers from $3,000/month for advisory or $4,000/month for full-service." First Page Sage's page states no price.

What does UPAI's service include?

UPAI's service has two parts: a free, hand-run check of whether ChatGPT, Claude, Gemini and Perplexity name your company when buyers ask their questions, and then the work of getting the company into the sources those assistants cite. We publish no price and sell no self-serve product.

You send your domain. We run the check by hand, which takes a few working days, and email your Mention Rate: the share of your buyers' real questions where an AI assistant names your company. The report is yours whether or not you hire us.

Our landing page lists four steps under "How we raise it":

1. Find the questions your buyers ask. Built from your category, your competitors' positioning and the wording in your own sales calls. You approve the list before we run it.
2. Find the sources those answers cite. Every answer arrives with the domains behind it, ranked by how often each one carries the answer for your category.
3. Get you into those sources, and fix what they say about you. Directory profiles, review-site pages, comparison articles. Where a source has you wrong, we file the correction.
4. Re-measure every week. Same questions, same models, fresh run, with the dates attached.

Under "What we don't do" the page lists guaranteeing rankings, case studies you can't verify, long contracts, and reporting traffic instead of mentions. Set against the five groups, our work is the audit, the off-site sources and the reporting. The page lists no on-site content production and no technical site work.

What should you receive as evidence that each piece of work was done?

For each of the five groups you should receive something you can open and check without the provider in the room: the dated answers, the changed pages, the placements, and the readings before and after. This is our checklist, not an industry standard.

The audit, off-site and reporting rows repeat what our landing page says comes with our work: the approved question list, the four items under "What you get every time", linked listings and the weekly re-measurement. The other two rows are what we would ask of a provider that sells that work; our page lists neither.

For Google Search, Google's AI guide says you can ignore "chunking" content, unnecessary AI text files such as llms.txt, and inauthentic mentions. If a proposal bills for one, ask which assistant it is for and on what evidence.

What can no generative engine optimization service promise?

No generative engine optimization service can promise your company will be named: none of the Google, OpenAI or Perplexity documents cited here says a service can make an AI assistant do that. Google says using a service or tool "doesn't guarantee ranking success", and that sentence covers Google Search only. OpenAI and Perplexity document a condition for being shown, not a promise of being named.

• On services. "Keep in mind that using a service or tool doesn't guarantee ranking success," says Google's guidance on third-party SEO tools and advice, whose list of third-party services and tools includes '"AEO" or "GEO" tools'.
• On forecasts. The same page: "They can't guarantee performance. Any predictions are their own and like predictions generally, may not happen."
• On inside knowledge. The AI guide: "No third-party tool has access to our internal ranking or AI systems."
• On Google rankings. Google's Do you need an SEO? page: "No one can guarantee a #1 ranking on Google."

Google does not promise the result either: its AI guide says meeting every requirement "doesn't mean that Google will crawl, index, or serve its content." The same guide says "seeking inauthentic 'mentions' across the web isn't as helpful as it might seem."

For ChatGPT and Perplexity the documents are the crawler pages. OpenAI recommends allowing OAI-SearchBot to "help ensure your site appears in search results" and says sites that opt out "will not be shown in ChatGPT search answers, though can still appear as navigational links". Perplexity recommends allowing PerplexityBot to "ensure your site appears in search results". Neither page uses the word "guarantee", and neither says how an answer picks the companies it names.

When are GEO services the wrong purchase?

GEO services are the wrong purchase when a cheaper step would answer your question first, or when what you want is a guarantee nobody can give. Four situations recur: your buyers reach you through Google alone, you have not measured anything yet, what you actually want is a dashboard rather than the work, or you need a guaranteed outcome by a fixed date. The first reading costs nothing and settles the first two cases in an afternoon.

• Your buyers reach you through Google alone. Google's guide says optimizing for its AI features is "still SEO". Our piece on appearing in Google AI Overviews lists the steps.
• You have not measured anything yet. A first reading costs nothing: check whether ChatGPT mentions your brand yourself, or send us your domain.
• You want a dashboard, not the work. Our overview of tools that track brand visibility in AI search covers that route.
• You need a guaranteed outcome by a date. Neither Google's guidance nor OpenAI's or Perplexity's crawler page offers one.
• You are not sure the spend fits your size. Is GEO worth it for a mid-size company covers that decision.

Questions people ask next

These are the follow-ups we are asked most often once the answer above has landed. The same rule applies to each: where a figure appears, its source and year sit in the same sentence, and where we do not know something we say so rather than estimate it.

Is generative engine optimization a thing?

Yes, as a name for a kind of work. Google's guide for site owners defines GEO as generative engine optimization and describes it, with AEO, as a term for work focused on improving visibility in AI search experiences. The same guide says that, from Google Search's perspective, that work is still SEO.

Are GEO services and AEO services the same thing?

The labels overlap. Google's guide treats AEO and GEO as two terms for work focused on improving visibility in AI search experiences. Optimist, an agency that sells both, writes that the terms are converging and the methodology underneath is the same. Compare deliverable lists, not names.

How long do GEO services take to show results?

We do not know, and we give no timeline. Optimist's page tells buyers to expect early signals within 1-2 months and compounding results over 6-12 months, and says realistic benchmarks depend on category and starting position. That is the agency's own claim; we have not tested it.

What do GEO services cost?

There is no market rate we can source. Omniscient Digital's GEO services page said on October 5, 2026 that full-service engagements start at $10,000 a month; that is one agency's published starting price, and the sentence is not specific to GEO work. Optimist's own agency ranking lists Optimist's retainers from $3,000/month for advisory or $4,000/month for full-service, and a one-time roadmap from $7,500. First Page Sage's service page states no price.
