What it does: Offers banner ads from national advertisers

What's cool: ValueClick has one of the largest pools of marketers and serves up ads for well-known brands, such as Netflix and eBay, that probably don't compete with your company. ValueClick also offers a separate service called Commission Junction, which pays small commissions every time clicks from your ads lead to a certain action, such as a purchase or filling out a form.

Drawbacks: The banner ads often feature video and other flashing graphics, which may distract visitors or tarnish your site's design.

What it pays: From 25 cents to $2 for every 1,000 people who see the ads
