The service enables brands to compare the sites, keywords and descriptions that produce the best results for them by tracking users' cookies from the search listing to conversion.
Advertisers can also channel budget into the best-performing promos, with data automatically collated and produced in a series of reports for immediate use by Overture's clients.
The release is part of the UK launch of Overture Performance Marketing (OPM), a division in the US. Marketing Console runs alongside Search Optimizer, an automating sponsored-search bidding and optimisation tool, as OPM's first two products.
Martin Child, managing director of Overture Northern Europe, commented: "With Overture Performance Marketing, advertisers will be able to increase the performance of their sponsored search campaigns. It will not only provide insights into which tactics and online channels work most effectively but also give them the option to automate bidding and optimisation strategies.
The UK launch is imminent and more information will be released at the beginning of 2005."
In the US, advertisers using Marketing Console are charged by the number of leads the service tracks on their behalf per month. For example, brands can track 40,000 leads for a monthly cost of $149 (£80).
