Contextured

Pay-per-click marketing: lovely in theory, but if you don't have the time to sit and learn about it and tweak your keywords accordingly, you won't get the return on investment you might expect from a PPC campaign. Contextured, though, takes the hassle out of PPC: built by a team of PhD scientists, it uses semantic technology to allow its users to manage their Google AdWords and Yahoo Search Marketing accounts in the easiest possible way. Founder Michael Oxley turned down a job at Swiss nuclear research facility CERN to start the business - so expect a lot from Contextured in the future.
