What is a survey distributed via social media primarily used for?

A survey distributed via social media is primarily used for gathering customer feedback quickly because it leverages the extensive reach and accessibility of social media platforms. These platforms allow businesses to connect with a large audience in real time, making it easier to collect opinions and insights from customers about products, services, or overall experiences. Social media surveys can be designed to be engaging and easy to complete, often leading to higher response rates compared to traditional methods. This instant feedback is invaluable for businesses aiming to make informed decisions and improvements based on customer preferences and satisfaction.

The other options do not align as well with the primary purpose of social media surveys. Collecting payment information is not suitable for social media, as it poses significant security risks. Promoting upcoming events may involve sharing information on social platforms, but that process typically doesn't use surveys. Evaluating vendor performance is usually conducted through more structured feedback mechanisms, rather than through casual social media interactions that tend to focus more on customer opinions.
