Kristin Lemkau, chief marketing officer at JPMorgan, says the bank has limited its web ads to 5,000 from 400,000 in an effort to improve the quality of ad displays; marketers have taken a programmatic advertising approach which features ads across the web based on browsing habits versus investment in individual sites; the new limitations for JPMorgan use a more customized white listing approach and are also the result of fewer ads on YouTube following recent issues.
