Can an agency guarantee we will appear in ChatGPT answers?

Why can nobody guarantee a place in ChatGPT answers?

An assistant writes each answer from what it retrieves and what it learned. You do not control that, and neither does your agency. Google makes the same point about its own system: no third-party tool has access to its internal ranking or AI systems⁵.

Answers also move. Commenters in one Hacker News thread noted that the same prompt can return different recommendations from day to day, and suggested tracking how often a brand appears over time rather than reading one output⁶. AirOps reports that only 30 percent of brands stay visible from one answer to the next, and that about 57 percent of brands that disappeared came back within two runs. Both figures are the vendor's own³.

What red flags should make me walk away?

These come from Google's own hiring guidance and from checklists published by agencies and editors. The agency checklists are written by firms that sell the service, so read them as one side's view.

• A guaranteed position, ranking or citation count. One GEO agency's checklist says no agency can guarantee specific positions in AI search results⁴.
• A fixed outcome on a fixed date, such as several-fold more AI visibility in 60 days or results inside the first 30 days⁴.
• A money-back guarantee tied to AI outcomes the agency cannot control⁴.
• A lock-in of 12 months or more before any result is shown⁴. A contract guide treats six months as a reasonable start and advises against 12-month commitments⁷.
• Claimed special ties to Google, or secrecy about what will be done. Google's hiring guide lists both as warning signs².
• One-off screenshots as proof, or claims of secretly submitting your site to AI models. An independent editorial guide lists both as red flags⁸.

What can a credible agency commit to instead?

Inputs and measurement. A scorecard from a content agency suggests checking for a defined tracking method (which engines, how often, and how mentions differ from citations), live reporting rather than a static deck, a clear answer on who will do the work, contract success measured in citation terms, and a refusal to guarantee what the agency does not control⁹.

Ask for these in writing:

• A baseline in the first week: the fixed set of buyer questions, the assistants checked, and what each one said about you.
• A report on the same questions at a stated cadence, showing for each question whether you were named, cited or missed, with the date.
• Work you can inspect: pages changed, facts corrected, access fixed, and a change log. Google's hiring guide says to ask for examples of past work, check references and ask that all changes be shared with you².
• A review point, for example formal reviews at 60 and 90 days, where scope changes if the numbers are flat⁷.

How do I check an agency's claims before I sign?

Run the test yourself first. Write about 20 questions a real buyer would ask, put them to two or three assistants, and log who appears and whether you are described correctly. Treat it as a sample, because answers vary⁸. Then ask the agency to show its own brand across the same assistants. One scorecard recommends checking whether the agency shows up in AI answers itself⁹.

Ask for references and speak to them. If an audit is offered, give read-only access to Search Console, not write access, and remember that you stay responsible for the actions of any company you hire². In an Ask HN thread about whether a monthly SEO retainer was worth it, commenters advised measuring conversions rather than traffic and treating domain-authority reports with suspicion¹⁰.
