Associated Content debuted a marketing campaign Monday featuring the online publishing service's most high-profile contributors, with the aim of attracting more free-lance talent, MediaPost reported.

The company currently tallies some 250,000 regular contributors of text, photos and videos, MediaPost reported, and it has collected more than 1.1 million pieces of content, which drew 9.3 million unique visitors in May, according to comScore.

The company works on a "yield-management system," which determines a one-time upfront fee of anywhere from $4-$20, and contributors then receive about $1.50 for every 1,000 page views.

Associated Content CEO Patrick Keane told MediaPost:

In terms of our growth, it's critical to encourage more free-lance talent to join our community of regular contributors and help us in delivering even more premium content for our users, as well as our advertisers and partners.
