# Find keyword gaps

Compare your client’s domain against competitors to discover keywords where competitors rank but your client does not.

## How Find keyword gaps works

The Find keyword gaps mode compares your client’s domain against one or more competitor domains. It identifies keywords where competitors rank but your client does not, revealing untapped opportunities.

## Running a gap analysis

1. Select **Find keyword gaps** from the research mode tabs.
2. Your client’s domain is pre-filled from the client settings.
3. Enter one or more competitor domains to compare against.
4. Set location and language filters.
5. Click **Find gaps**.

The system uses domain intersection data to find keywords where competitors have rankings but your client does not.

## Prioritizing gaps

* Sort by **search volume** to find the highest-traffic opportunities first.
* Filter by **difficulty** to focus on achievable keywords.
* Look for keywords where multiple competitors rank — these are likely important topics in your industry.
* Save promising keywords to a list, then use them to create content projects in the Copywriter.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.rankability.com/researcher/find-keyword-gaps.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
