# How to add a profiling question?
When setting up your brand lift, you have the option to add a profiling question for an additional cost of €200.
Our team of experts has carefully designed a library of profiling questions, so you can simply choose the one that best fits your needs. There are **over 200 profiling targets available, across more than 10 languages.\*\***
To add a profiling question, just select “Add a profiling question” while creating your measurement. You’ll then see a list of available options, allowing you to pick the category that most closely matches your target audience, or search directly by keyword.
**Please note,** the proportion of your target audience that fits a specific profile (the "incidence rate") can vary. For this reason, we recommend considering an audience boost that aligns with your selected question. This helps ensure you’ll have enough responses to accurately understand your sub-target once your brand lift is complete.
***
\*Please note: We are unable to take custom requests for new profiling questions at this time.
**Currently supported languages for profiling questions include:** French, English, Spanish, Italian, Portuguese, German, Dutch, Chinese, Arabic, Japanese, and Korean.

## 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://support.happydemics.com/launch/survey-customisation/how-to-add-a-profiling-question.md?ask=&goal=
```
`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.
