Mobile signup ad platform Pontiflex has revealed the costs of targeting US swing states – those in which no party has the support of a consistent majority – as political marketers increasingly turn to mobile campaigns to connect with voters, raise donations, engage volunteers, and build petitions.

The cheapest swing states to run the ads in are North Carolina, Pennsylvania and Virginia, ranging from a cost $1.29 to $1.31 per sign up. The most expensive is Montana, which costs $3.84 per sign up.

Political campaigns which target all swing states pay a blended average cost of $0.85 to $1.00 per signup. 

“In 2008, the Obama Presidential Campaign used signup ads to build email and social communities and help get the President elected. Today, weve built on that relationship and are working with a large number of political candidates and campaigns as theyve taken their campaigns mobile,” says Zephrin Lasker, Co-founder and CEO, Pontiflex. “We’re glad to help them as they look to grow and mobilise their support base.”
