Brand surveys allow users of Twitter to optionally share their perceptions of different companies and products. These surveys are linked to within Tweets from the @TwitterSurveys account.
If you see a Tweet from @TwitterSurveys, you have been randomly selected to participate in a brand survey. If you do not want to participate in the survey, simply don't click on the Tweet from @TwitterSurveys and/or click the dismiss button on the Tweet.
Your responses are anonymously collected and added together with many other responses. They are not tied to you personally and are anonymous when analyzed.
No. Your choice to respond or not to the survey will not alter your overall Twitter experience.
Thsese surveys are intended to help brands understand how they are perceived and the effect of their ads. This is a standard industry practice across many digital platforms.
