Yahoo CEO Marissa Mayer has been quite vocal lately, first saying she wants original programming to go along with a supposed upcoming Yahoo streaming service, and now the CEO has got her eyes set on search once again. A report citing sources close to the matter said that Mayer and Yahoo SVP of mobile and emerging products, Adam Cahan, have spearheaded as many as two projects aiming, at least in part, to dethrone Google as Apple's go to search choice on its sought after iOS platform.

Sources said the two projects are centered around building a mobile search engine, some kind of mobile monetization platform and largely hinged on getting a deal with Apple. Mayer is said to be quite a ways along with presentations for Apple execs regarding moving Yahoo search into the number one spot on Safari for iOS. The company is apparently in the process of creating a detailed presentation with images of how things could shape up.

"This is the aim of the whole effort here, to grab the pole position in iOS search," one source working on the initiative told Recode. "It will take more than pretty pictures, though, to convince Apple to give up Google, given its focus on consumer experience being top-notch. But Marissa wants it very badly."

Google search is still the default search option for Apple, but the company does have a good relationship with Yahoo. Apple's default iPhone stock and weather apps are powered by Yahoo technology, and it looks as though Mayer hopes to extend this relationship into a much bigger arena. However, with the $1 billion in various fees it pays Apple every year and its unarguable dominance in the field, Yahoo and CEO Marissa Mayer have quite a job ahead of them replacing Google as Apple's go to mobile search engine.
