responses - that's how we get the inferred demographic data. Some of that inferred data is based on browsing behaviour so we know your interests based on sites that you've gone to and seen. That's a possibility, for sure - to tie browsing interests to answers in the survey. But I don't think we'll do much beyond that for privacy reasons. Could a publisher tie GCS data from readers to their Google Analytics data? PM: We don't share the survey data with publishers, but publishers can run their own surveys. Some percentage of their traffic gets dedicated to their own surveys. The ones that they run themselves aren't charged for, but they aren't paid for them either. But right now we don't have any plans to tie survey data back to Analytics data. Follow us on Have your say Please do not complete the following form field for security reasons.
