Need to boost site traffic? The idea of handing over hundreds, often thousands, of dollars for premium ad space or trading (begging for) links may be keeping you up at night.

Here’s an option. Adgridwork is an open (free) advertising network that lets bloggers and publishers barter their own real estate for advertising space on any of the thousands of sites in the Adgridwork network. You can choose what types of sites your ads appear on, and even monitor campaign progress, like impressions and conversions, through Adgridwork’s free metrics and tracking tools.

To get started, register your website or blog with the network, defining your site by category and any relevant keywords. This helps Adgridwork target advertisements to specific audiences. Once approved, your site is added to the mix and open for serving ads. In exchange, you ads will start running on other sites in the network. Adgridwork uses a simple merit system to reward its supporters- the more ad click-through’s your site generates, the more sites your ads appears on.

If you’re looking for a simple way to generate traffic or just tired of paying for ad services, consider using Adgridwork to promote your site.
