Generative engines answer questions by combining definitions, facts and opinions from many pages. When your industry uses terms loosely, assistants often merge concepts or attribute the wrong meaning to your offer. One of the simplest generative engine optimization (GEO) tactics we use with clients is to publish a glossary first, then build service and article pages that use its definitions consistently.
The problem with fuzzy vocabulary
In overseas advertising, terms such as "agency account", "whitelisted account", "top-up", "spending limit" and "account suspension" mean slightly different things depending on the platform and the speaker. If a provider uses "agency account" to mean three different arrangements across its site, an assistant summarizing that site will produce an unclear or incorrect description. Buyers then ask follow-up questions, or leave.
The same applies in payments ("settlement" versus "payout"), multilingual websites ("translation" versus "localization") and AI search ("GEO" versus "AEO" versus "AI SEO").
What a useful glossary contains
- One entry per term, with a two-to-three sentence definition in plain language.
- Scope notes: which platforms or markets the definition applies to.
- Related terms and how they differ.
- A link to the service or guide page where the term matters in practice.
- A last-reviewed date, because platform terminology changes.
Keep entries factual. A glossary is not a sales page.
How it improves AI answers
- Disambiguation. Assistants can quote a short, self-contained definition rather than inferring one.
- Consistency. When service pages use the same wording, the model sees repeated, aligned statements about what you do.
- Entry points. Definition-style questions ("what is a whitelisted ad account") are common prompts; a clear glossary entry is a natural citation target.
Implementation steps
- List the 30–60 terms your sales team explains most often.
- Write definitions with someone who handles client questions daily.
- Publish on one indexable page, or one page per term if entries are long, with anchor links.
- Audit service pages and replace inconsistent wording.
- Link from articles to glossary entries on first use of each term.
- Review quarterly.
Measuring results
Track a set of definition prompts and service prompts monthly. Note whether assistants use your phrasing and whether the description of your services becomes more accurate. In our client work, the accuracy of descriptions usually improves before citation frequency does.
Common objections
"Our competitors will copy it." Possibly, but definitions are not a moat; clarity and consistency across your site are.
"It is too basic." Basic questions are exactly what new buyers and AI assistants ask.
Conclusion
A glossary is low-cost, durable content that makes every other page easier to understand. For a working example in overseas advertising, see our overseas advertising glossary.
