Online auction site LabX introduced an advanced advertising feature that improves seller exposure in search engines. The new feature lets a LabX user automatically promote their listing simultaneously in Google Adwords and Overture search engine campaigns. This creates additional exposure for their LabX listing while eliminating the expensive time costs involved for a seller to set up and administer their own search-engine marketing campaign. The search-engine listing campaigns draw upon LabX expertise and historical data for the appropriate keyword strategy. LabX is an online marketplace for scientific products.
