  a) Running a random call campaign to determine the number of people salient about the message or
  issue awareness you are attempting to get out to the public
  b) Click through rates, site visit statistics, and how many people are adding the site as a friend or
  fan on a social networking site
  c) Hold town hall meetings and discuss the issue or message in order to determine how many people
  were informed about the issue
  d) Write an article for the newspaper requesting that people write or call in to poll their opinions and
  knowledge of the issue being discussed
