He also called Mayer's plan to become part of people's lives an "audacious goal."
Brad Shimmin, an analyst with CurrentAnalysis, said convincing Yahoo's user base that the company is committed to mobility will be another challenge.
"I think original content is the key to Yahoo's future," he added. "The company doesn't have to become another Bloomberg or Time Warner in order to succeed here. It merely needs to weave excellent news, opinion, sports, etc., throughout its existing collaboration services to convince users to start their morning with Yahoo."
Shimmin also said Mayer did a good job laying out her plans to Yahoo employees without getting bogged down in weighty details.
"I think at this point, any effort that rallies the company's assets around a small set of relatable objectives, such as mobility and content, will result in an improved outlook for Yahoo," he said.
