With 68% of U.S. voters heading online before they vote to do research on local ballot initiatives, being online is crucial to getting elected. Politicians and issue advocacy groups maintain channels on YouTube during elections— and for advertising, most campaigns get their messages to constituents through online ads across search and Google Display Network with tactics like Google Blasts.
“Using In-Stream Ads, candidates and issue advocacy groups have reached millions of U.S. voters this primary season. It straddles that line between digital and TV advertising: most campaign managers and political agencies are taking their standard made-for-TV 30-second ads and simply re-purposing them to run on YouTube. Campaigns can target locations (like their state or district), as well as content categories on YouTube, allowing them to tailor their message to specific groups of constituents,” explains Google.
