# Do you prevent duplicate survey responses?

**Yes**, TalentMap recommends using a unique URL for each respondent. Each respondent obtains it's own unique URL and once completed the link is closed and cannot be accessed again.

A key challenge with survey deployment is to ensure we get a sufficient response rate, however, we do ensure respondents don't complete the survey more than once.

The ideal deployment method is using a unique URL which is specific to the individual respondent. Once that survey is completed the link is closed and can't be used again or re-accessed.

If deploying by unique URL is not an option and the survey is launched using an open link, TalentMap has means for checking duplicates including looking at response rate patterns, reviewing open-ended comments etc.

## 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://docs.talentmap.com/site-faq/faq/survey-design/do-you-prevent-duplicate-survey-responses.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.
