Generative engine optimization services: what a GEO agency should do

A generative engine optimization service should do four things: make sure AI crawlers can reach and read your site, rewrite key pages into passages an answer engine can quote, earn mentions and listings on other sites, and measure your citations across engines before and after. Anything sold as a GEO service that skips the measurement, or promises a citation, is not doing the job.

Ranked for a startup that wants that work done by hand, with a fixed scope and proof of what shipped, LaunchScaler's SEO / GEO boost comes first below, followed by the other kinds of provider worth considering and a checklist for judging any of them.

What does a GEO agency actually do?

GEO work is ordinary technical and off-page SEO aimed at a different reader: the systems that retrieve pages for ChatGPT, Perplexity, Claude, Gemini, Copilot and Google's AI features. It has four parts, and each has published evidence behind it. A proposal that cannot map its tasks onto these parts is selling something else.

Access and rendering is a one-time technical fix, usually measured in days of work rather than months. Quotable passages are writing work on your own pages. Third-party mentions are the slow, human part, and they are where most of a provider's time should go. Measurement brackets all of it. The explainer on generative engine optimization covers the research behind the quotable-passages row.

Which GEO service providers are worth hiring?

For a startup, the deciding criteria are a fixed scope, work done by people rather than link networks, and a record of every deliverable you can check. On those, the order is LaunchScaler's SEO / GEO boost, a technical SEO consultant, a digital PR firm, a full-service agency with a GEO practice, and a tracking platform run by your own team.

1. LaunchScaler: SEO / GEO boost

LaunchScaler's SEO / GEO boost is done-for-you off-page work in four workstreams: guest placements on real, publishing sites with links a human editor chose to give; structured-data fixes for your product, organisation, FAQs and reviews; answer-engine optimisation that makes your pages quotable, with clear claims, sourced facts, an llms.txt and passages an engine can lift; and technical off-page clean-up of redirect chains, canonical mismatches, lost backlinks and broken citations.

It starts at $299 and is quoted per project. It is inquiry only: nothing is charged on the page, and LaunchScaler replies within one business day with a scope and a quote. The process runs from an audit of your off-page footprint, through a plan scoped to where your site stands, to the work done by hand. You get a record of every placement and every fix, linked and checkable. LaunchScaler states it never buys links from networks, runs private blog networks or fakes reviews and mentions, and that if a placement does not happen, it tells you so. It suits a founder who wants the off-page work done without hiring an agency on retainer. Talk to us with your URL for a scope.

2. A technical SEO consultant, for access and rendering

If your problem is that AI crawlers cannot read the site, a technical consultant fixes it fastest. The work is robots.txt groups per bot, firewall rules for verified crawler IP ranges, and moving content from client-side rendering to server rendering or prerendering. Ask for before-and-after evidence: the raw HTML showing your content, and a 200 for each retrieval bot's user agent.

3. A digital PR firm, for third-party mentions

Mentions on other sites are the part you cannot do from your own domain. A PR firm pitches journalists, newsletters and podcasts to cover your product. Judge it by named placements in publications your buyers read, with or without a link, since a plain mention still counts. Rule out any firm that pays for coverage with followed links, which Google classes as link spam.

4. A full-service SEO agency with a GEO practice

An agency can run all four parts together, which suits a company with a marketing team to brief it. The risk is a retainer spent on activity rather than outcomes. Insist on the same measurement baseline you would ask of anyone else, and on a list of deliverables per month rather than hours.

5. A GEO tracking platform run by your own team

Tracking tools show where you are mentioned and cited, and some suggest content gaps. They do not do the work. They suit a team with the time to act on what the tool reports. The comparison of GEO and AEO tools covers the options.

What are the red flags in a GEO proposal?

The clearest red flag is a guarantee. Neither Google nor OpenAI offers one: Google says "indexing and serving isn't guaranteed" even for pages that meet every requirement, and OpenAI says model outputs "may differ from request to request." A provider cannot promise what the engines themselves do not. The table lists the others and why each is a problem.

Mentions work because they are earned. The comparison of brand mentions and backlinks for AI explains why a genuine unlinked mention can outweigh a bought link, and the guide to link building for startups covers the legitimate way to earn both.

How should you measure a GEO provider's work?

Agree the measurement before the work starts, and use the same method after. Pick 15 to 30 real buyer questions, run each on the same engines the same number of times, and record how often you are mentioned and cited. The difference between the two runs is the result; anything else is a claim.

1. Write the questions a buyer asks before choosing a product like yours, including comparisons and "best tool for" questions.
2. Choose the engines: ChatGPT, Perplexity, Claude, Gemini, Copilot, Google AI Overviews and AI Mode cover the main ones.
3. Run each question several times per engine, since one run is a sample of one.
4. Record for each run whether you are named, whether you are linked, which of your pages is linked and which competitors are named.
5. Repeat the identical set after the agreed period and compare the rates, not individual answers.

Keep the baseline yourself, or have it produced by someone other than the provider being judged.

What should you ask any GEO provider before signing?

Ask questions that force specifics. A provider doing real work can answer each one with a document, a list or an example; one that cannot is selling a label. Put the answers in the contract as deliverables.

1. What will you change on my site, page by page, and when?
2. Which third-party sites will you pitch, and will every placement be one an editor chose to publish?
3. Do any placements involve payment for a followed link?
4. How will you measure mentions and citations before and after, on which engines and with how many runs?
5. What will I receive at the end: a list of every fix and placement with links, or a summary?
6. What happens if a placement you planned does not happen?
