The campaigns are developed based on the demographics and characteristics of the people that Clash-Media's clients would most like to target. Ads are served via Clash-Media's Lead and Data Network, which consists of more than 500 websites and publishers including GMTV, Tiscali and MySpace.
Clash-Media then verifies and "cleanses" leads, which are delivered directly to the client. The speed of turnaround means businesses are more likely to have successful conversions, according to Clash-Media.
The new service follows on from successful campaigns that Clash-Media developed for Firstplus, MBNA and Ocean Finance.
Diana Herriott, marketing director for Clash-Media, said: "While pay-per-click and keyword searches are often very successful, many companies are finding that it can become a very expensive way of generating interest in a brand. The advantage of online lead generation is that companies can qualify a set of leads before they have even paid for them.
"For example, a company may only want to target a certain demographic of people based on how much they earn per year, and because we have a fully opted-in lead process and strict verification procedures it enables us to do just that and produce the highest quality of leads for the client."
Clash-Media's clients currently include Whiskas, Toyota, Cheapflights, AXA and Orange.
