A GEO agency helps your brand get found, cited and described accurately inside ChatGPT, Perplexity, Gemini, Google AI Overviews and Copilot, using the same rigor good SEO agencies apply to traditional rankings: real audits, real content, real technical work and honest measurement. Be direct with yourself before you hire one: no agency, including Agentixly, can guarantee a citation in any AI answer engine, because these systems are non-deterministic, personalized and controlled entirely by companies outside any agency's reach. This guide covers what real GEO work includes, 12 questions to ask, the red flags that predict a wasted budget, and the KPIs worth paying for.
What Does a GEO Agency Actually Do?
Generative engine optimization, GEO, is the practice of making a brand easy for AI answer engines to find, understand and cite accurately. For a deeper definition and how the discipline relates to search overall, see our explainer on what GEO is. A GEO agency's actual scope of work falls into five areas, and a finalist should describe its approach to each one specifically, not in general marketing language.
- AI visibility audits: structured testing of how your brand and competitors appear across ChatGPT, Perplexity, Gemini, Google AI Overviews and Copilot for a defined set of buyer-intent prompts, run repeatedly rather than once.
- Entity and schema clarity: making sure your brand, products and named experts are unambiguous entities, described consistently across your site, structured data and third-party profiles.
- Authoritative content: long-form, fact-checked content that answers real questions in depth, structured so a model can extract a clear, correct claim from it.
- Earned citations and digital PR: mentions and links from third-party sites that models treat as corroborating sources, not content published only on domains the agency itself controls.
- Technical access and measurement: confirming AI crawlers can reach your content, and building a repeatable way to know whether any of this is working.
If a GEO agency's pitch stops at the first item on this list (an audit) or the last one (a technical checklist), you are buying a fragment of GEO, not the discipline. The work only compounds when all five run together.
GEO Agency vs SEO Agency vs In-House: Who Should Own This?
For most companies, GEO is not a separate discipline from SEO so much as a new measurement layer and a few new workstreams bolted onto the same foundation. Technical crawlability, authoritative content and structured data serve traditional rankings and AI citations at the same time, which is why we break down the full comparison in SEO vs GEO.
A dedicated GEO agency earns its place when you need deep, platform-specific tracking across several AI tools, or when your existing SEO partner has no credible AI measurement practice and will not build one. An in-house owner still matters in either case: one person on your team should hold the prompt panel, the reporting cadence and the relationship, the same way you would not outsource ownership of your Search Console account. When you are also evaluating traditional SEO partners, our companion guide on how to choose an SEO agency covers the parallel questions for that side of the work.
How AI Crawlers Actually Work: What a Technical GEO Partner Should Know
Content and citations only matter if AI systems can reach your site in the first place, and this is where a lot of GEO advice gets vague or wrong. Each major provider publishes its own named crawlers with their own purpose and their own robots.txt controls, and a technically credible GEO partner should know the difference between them without checking notes.
| Platform | Crawler names | What each does | robots.txt control | | --- | --- | --- | --- | | ChatGPT (OpenAI) | GPTBot, OAI-SearchBot, ChatGPT-User | Model training, search indexing, live user fetches | GPTBot and OAI-SearchBot honor it separately; ChatGPT-User may not | | Claude (Anthropic) | ClaudeBot, Claude-SearchBot, Claude-User | Model training, search indexing, live user fetches | All three are controlled separately | | Perplexity | PerplexityBot, Perplexity-User | Crawling and indexing, live user fetches | PerplexityBot honors it; Perplexity-User generally does not, since a user requested the page | | Google AI Overviews and AI Mode | Googlebot, no separate crawler | The same crawl and index that power regular Search results | Blocking Googlebot removes you from Search and AI Overviews together | | Gemini apps and model training | Google-Extended, a token rather than a crawler | Controls whether crawled content trains Gemini and related models | Disallow it without affecting Search or AI Overviews eligibility | | Microsoft Copilot | Bingbot | Copilot grounds its answers in Bing's index; there is no separate Copilot crawler | One rule for Bingbot governs Bing, Copilot and related surfaces together |
Two details in that table trip up most GEO advice. First, AI Overviews are not a separate opt-in feature: Google is explicit that there are no additional requirements, no special machine-readable files and no special schema.org markup needed to appear there, and that indexing is never guaranteed regardless of what a page does. Second, an llms.txt file (the proposal Jeremy Howard published in 2024 to help AI agents navigate a site's content more efficiently) is a convenience file, not a ranking signal; no provider in the table above treats it as a citation input. A GEO agency that leads with "we will add your llms.txt" as a headline deliverable is leading with the least important item on the list.
12 Questions to Ask a GEO Agency
Send these before the pitch meeting and ask for answers about your brand specifically, not about the agency's process in the abstract.
Scope and Diagnosis
| # | Question | A good answer sounds like | Walk away if you hear | | --- | --- | --- | --- | | 1 | How does our brand currently appear across ChatGPT, Perplexity, Gemini and AI Overviews? | Specific findings from a real prompt panel run before the call | "We will find out after onboarding" | | 2 | Which prompts and buyer stages are you tracking, and why those? | Prompts mapped to how your actual buyers research and compare | A generic list unrelated to your product | | 3 | How does this work relate to our existing SEO program? | A plan to share technical and content foundations, not a rebuild | "GEO replaces SEO" | | 4 | What can you realistically influence, and what is out of anyone's control? | A clear line between content, schema and citations versus placement | A promise of guaranteed visibility |
Technical and Content Execution
| # | Question | A good answer sounds like | Walk away if you hear | | --- | --- | --- | --- | | 5 | Which AI crawlers can reach our site today, and which are blocked? | A specific audit of GPTBot, ClaudeBot, PerplexityBot and related rules | No knowledge of specific crawler names | | 6 | Who implements schema and content changes? | Tickets or pull requests in your stack, with an owner and a date | "We send recommendations to your team" | | 7 | How do you earn third-party citations? | Digital PR, expert positioning, original data, each with a source | Content posted only on sites the agency controls | | 8 | How do you keep content accurate as facts and products change? | A review and refresh cadence tied to releases or policy changes | No process; content is published once and left alone |
Measurement and Terms
| # | Question | A good answer sounds like | Walk away if you hear | | --- | --- | --- | --- | | 9 | How do you measure AI visibility, and how often? | A repeated prompt panel across models, with a defined sampling method | A one-time snapshot presented as an ongoing metric | | 10 | Can we see the raw prompts and outputs behind your reporting? | Yes, with the panel and transcripts available to you directly | Only a proprietary score you cannot inspect | | 11 | Who owns the content, schema and tracking setup if we leave? | You do, in your own accounts, from day one | Work built on the agency's own tools or logins | | 12 | What is the contract term and exit process? | A short initial term or paid pilot, then a notice period | A long lock-in signed before any deliverable exists |
Questions 4 and 9 carry the most weight. Question 4 tells you whether the agency is honest about what GEO can and cannot promise, and question 9 tells you whether its measurement is a real, repeatable method or a one-off screenshot dressed up as a report.
Red Flags and Snake Oil to Watch For
The GEO market is new enough that confident-sounding vendors can say almost anything without much pushback yet. Slow down, or walk away, if you see any of these:
- Guaranteed placement in ChatGPT, Gemini or any AI tool. No agency controls a third-party model's output. A guarantee is a sign the agency does not understand the systems it is selling access to, or is comfortable misleading you.
- Hidden text or prompt-injection tactics. Content written to manipulate a model into citing or favoring a brand, hidden from human readers, is a policy violation on most platforms and a durable trust risk if discovered.
- llms.txt sold as the whole strategy. It is a helpful convenience file at best, not a citation mechanism, as the crawler table above shows.
- Reporting built only on a proprietary visibility score. If you cannot see the underlying prompts and outputs, you cannot audit whether the number means anything.
- No named platforms or prompts. "We optimize for AI search" without naming which models and which prompts it tracks is not a measurable claim.
- Recommendations with no implementation. An agency that hands your developers a document and calls it done rarely produces shipped change.
- Lock-in before any deliverable exists. A twelve-month contract signed before you have seen a single audit or report.
- Silence on the difference between GEO and SEO. An agency that cannot explain what actually changes between the two disciplines likely has not done the work to know.
How Much Does GEO Cost?
GEO pricing follows the same models as SEO, and the model matters more than the headline number because it determines what you are actually buying.
| Pricing model | Typical market range | Best for | Watch out for | | --- | --- | --- | --- | | Hourly or project audit | 2,000 to 10,000 dollars for a one-time AI visibility audit | A first look before committing to an ongoing program | An audit with no prioritized follow-up plan | | Monthly retainer | 2,000 to 8,000 dollars for small and mid-market companies; higher for enterprise or multi-market work | Ongoing content, schema and citation work plus tracking | Paying for activity with no visibility into results | | Bundled with SEO | A blended retainer covering both disciplines | Companies that want one accountable team | Unclear which budget line pays for which deliverable |
These are typical market ranges, not a price list; actual quotes vary with the number of platforms tracked, content volume and how many markets or languages you operate in.
Illustrative scenario: a Series B B2B SaaS company already spends 8,000 dollars a month on SEO and adds a 3,000 dollar monthly GEO scope covering a 40-prompt panel across four models, entity and schema cleanup, and one earned citation campaign per quarter. Assuming the combined program influences even a small share of the deals sourced through organic and AI-assisted research, the relevant comparison is not the 3,000 dollar line item against total revenue, but against the cost of one lost enterprise deal where a buyer's AI research surfaced a competitor instead. The numbers here are illustrative; treat the comparison as a way to frame budget, not a forecast.
What KPIs Should a GEO Agency Report?
GEO measurement is younger and noisier than SEO measurement, so the KPIs that matter are the ones you can inspect yourself, not the ones with the most impressive-looking dashboard.
| Instead of | Report this | Source | | --- | --- | --- | | A single "AI visibility score" | Citation rate and mention rate across a fixed prompt panel, by model | Repeated prompt runs, logged and shared | | One screenshot of a good answer | Sentiment and factual accuracy of mentions over time | Manual or automated review of the same transcripts | | Total site traffic | AI referral traffic identified by source in your analytics | Analytics, filtered for known AI referrer domains | | Nothing tied to search behavior | Branded search lift following content and citation pushes | Search Console and analytics, read together | | A vague sense of AI presence | Generative AI appearances in Google's own reporting | Search Console's generative AI performance report |
Google added a dedicated generative AI performance report to Search Console, showing impressions and pages that appeared inside AI Overviews and AI Mode by country and date. It is the only first-party visibility data any of the major AI platforms currently publish back to site owners, which makes it worth checking directly rather than trusting a summary of it.
Illustrative scenario: assume a 40-prompt panel run monthly across four models for a mid-market fintech brand. In month one, the brand is mentioned in 12 of 160 total responses (a 7.5 percent mention rate) and cited with a link in 5. By month four, after entity cleanup and two earned citations on trusted publications, mentions rise to 34 of 160 (21 percent) and citations to 15. The assumptions and figures here are illustrative, meant to show the shape of a credible report, not a result any program can promise.
How Agentixly Approaches GEO Engagements
Agentixly treats GEO as an extension of engineering-led search work, not a separate marketing add-on, because the same team that ships schema, server-side rendering and site structure can also fix the technical gaps that keep AI crawlers out. A typical engagement moves through four phases: an AI visibility audit across the major platforms using a prompt panel built for your buyers, entity and schema cleanup alongside technical crawler access, content and earned-citation work aimed at third-party corroboration rather than only your own domain, and monthly measurement reported with the underlying prompts and outputs, not just a score.
Because our GEO specialists work alongside our SEO team and web engineers, technical fixes ship in your codebase instead of sitting in a slide deck, and GEO and SEO are planned as one program rather than two vendors billing separately for overlapping work. What you get: your own accounts and tracking setup, a prompt panel you can see in full, and no promise of a citation we cannot actually control.
The Bottom Line
A GEO agency is worth paying for when it treats AI visibility as a measurable discipline: named platforms, a repeatable prompt panel, real technical and content work, and reporting you can audit yourself. It is not worth paying for guaranteed placement, a hidden-text trick, or an llms.txt file sold as a strategy, because none of those are how these systems actually work.
If you want a program built on that discipline, explore Agentixly's GEO services or tell us which platforms and prompts matter to your buyers. We answer every inquiry within 24 hours.
