The biggest GEO and AEO agency red flags are not a lack of AI jargon. They are guarantees, untestable methods, missing evidence, weak approval controls and proposals that cannot explain what the agency will actually change.
GEO, AEO and LLM SEO are not official Google categories. They are overlapping labels for making reliable buyer information easier to find, understand and use across search and AI-assisted discovery. The practical priority is stronger conventional SEO, clear facts and evidence—not a promise of AI mentions.
Choose a consultant for senior diagnosis and internal enablement, an agency for coordinated execution, or a hybrid model when your experts can approve facts quickly but cannot run the full programme.
