The Difference Between GEO, AEO And LLM SEO
Size is less of a factor than category maturity. Smaller brands often gain faster because their categories have thin third party coverage, and thin coverage is easier to influence than a category where every comparison page has been fought over for a decade.
Assertions with nothing behind them are weaker than silence, because they introduce a detail that fails verification. The pattern that works is reciprocal: your site names the profile, the profile links to your site, and some independent source associates the two without either of you being involved.
What Transfers to an Ordinary Business Three things, and they are the three that most small operators skip. Check that you are readable before assuming you have a content problem, since on a small site an access failure is total rather than partial.
Inside your own organisation, the useful move is to write a single sentence defining whichever term you adopt and put it wherever your team will see it. Most of the confusion these acronyms cause is internal rather than external, with two people using the same word for different scopes and discovering the mismatch three months into a project.
The Job in One Sentence An AI SEO agency makes your brand legible, quotable and trustworthy to the systems that now trusted answer engine optimization agency questions on behalf of your buyers. Legible means a machine can parse who you are and what you sell without guessing. Quotable means your pages contain passages an assistant can lift and attribute cleanly. Trustworthy means enough independent sources agree with you that a model treats your claims as settled rather than promotional.
How to Test Rather Than Trust Everything above is a starting hypothesis. Run twenty prompts in your own category across all three, from signed out sessions, recording the mode and the date, and count the cited domains for each.
Accuracy Beats Coverage The most common real defect is not missing markup, it is markup that disagrees with the page or with the rest of the web. A founding year in your schema that differs from your about page. A logo URL that returns a 404. A contact point nobody monitors.
It also appears more conservative in commercial categories, hedging or declining to make a direct recommendation more often than the others. Where it does recommend, established entity signals seem to matter, which favours brands with consistent details and long records over newer entrants.
What a Defensible Business Case Looks Like It states what cannot be measured. It reports inputs completed, with counts. It reports prompt set movement as fractions with visible run counts, split by intent. It includes the soft signals as anecdote clearly labelled as anecdote. It attributes every external statistic.
No, though the foundations overlap. The measurement, the target surfaces and the emphasis on third party sources are genuinely different, and the Ahrefs overlap data shows the two channels draw from largely separate pools of pages.
A quick way to find contradictions is to write out your key facts on one sheet, taken from your structured data, then check that sheet against your about page, your main directory listing and your marketplace account. Doing it manually feels crude and it surfaces the conflicts that validators never flag, because a validator checks syntax rather than whether your founding year matches the one you published elsewhere.
That emphasis is worth watching, since retrieval is where most current influence actually lies. A proposal built primarily on getting into training data is describing a slower and far less controllable mechanism than one built on being retrievable now.
Who Actually Needs One If your buyers research before they purchase, you are exposed. Software, professional services, healthcare, home services, equipment and anything with a considered purchase all show heavy assistant use at the research stage. If people buy from you on impulse or purely on price at the shelf, this matters far less.
Where It Overlaps With Classic SEO A good deal of the groundwork is shared. Crawlable pages, sensible internal linking, fast rendering, accurate structured data and a clean information architecture all help both a search crawler and an AI crawler. If your site fails those basics, an agency will fix them first, and you should be suspicious of anyone who skips straight to the exotic work.
It does not contain a return on investment figure calculated from an assumed conversion rate applied to an estimated mention volume. That calculation looks rigorous and is a chain of guesses, and it will not survive the first person who asks where the first number came from.
One practical consequence of the variation between systems is worth planning for. If your customers are split across two assistants that behave differently, resist building separate programmes for each. The shared requirements account for most of the achievable outcome, and the effort spent on system specific tactics is usually better spent widening the number of third party sources that describe you correctly.
