## At a glance

1. **Find a gap**: Open Intelligence → Vocabulary and select Topics with gaps.
2. **Open the terms**: Choose a topic and theme row to see each missing term and the cited pages using it.
3. **Check the context**: Read the cited pages and relevant answers before deciding whether the language belongs on your page.

Open [Intelligence → Vocabulary](https://app.knitknot.ai/intelligence/vocabulary) to compare the language on your pages with language on cited pages for the same buyer topics. A gap points to a term worth investigating. It does not, by itself, show that adding the term will change an AI answer.

## Find a topic and theme

Select **Topics with gaps** to see topics with cited vocabulary absent from your pages. **Fully covered topics** shows topics with no missing cited vocabulary in this analysis. The **Missing terms** tile counts distinct absent terms across the current topics, and **Corpus freshness** shows how recently the underlying page corpus was checked when a date is available.

Search for a topic or filter the table by **Topic** or **Theme**. Each row pairs a buyer topic with a theme. **Gap terms** counts missing terms for that row; **Covered** is the share of its analyzed terms already present on your pages. The table starts with the lowest coverage, but a low percentage alone does not tell you which page to edit.

For example, a “call recording compliance” theme might have terms absent from your pages. First check whether your product actually supports the relevant compliance requirement. A term found on a competitor's page may describe a capability you do not offer.

## Inspect the cited pages

Open a topic and theme row. The detail lists each **Gap term** beside a **Winning page** that uses it. **Uses on page** counts occurrences of that term on the page. **Citations** and **Engines** show its presence in the measured answer set. Search for a term or page, or filter by term, owner, and engine. Open a page row to inspect its source record and cited answers.

Read the passage around the term on the cited page and the buyer question that led to the answer. Then compare it with your own page and [approved facts](/docs/review-and-approve-facts/). If the term is accurate and helps answer a real question, revise the relevant page. If it is jargon, a rival-only claim, or unrelated to the question, leave it out.

When the page labels the result **Directional**, its term weighting comes from a broader cited-page corpus rather than only answers where your company was absent. Treat its ranking as a lead for review. If the view says **Your pages use the vocabulary AI cites**, it found no gaps across the topics analyzed; that is not a verdict on every possible buyer question.

Vocabulary gaps concern wording on pages. For missing page types across topics, use [Content coverage](/docs/find-content-coverage-gaps/). For themes that recur across answers and cited pages, use [Cited themes](/docs/read-cited-themes/).
