Steckler joined AOL UK from MSN in July as vice-president of interactive marketing, as well as interim managing director.
His appointment comes as AOL unveils Platform A, which will offer advertisers access to targeting and measurement tools across the platform's network of third-party sites, as well as sites owned and operated by AOL.
Platform A builds on Advertising.com, which operates the largest third-party display network, and integrates behavioural targeting company Tacoda, mobile media network operator Third Screen Media, video ad-serving platform Lightningcast and Adtech's global ad-serving platform.
AOL also announced that it would move its corporate headquarters to New York from Dulles, Virginia.
