AllThingsD says Yahoo will lay out its turnaround strategy for its employees tomorrow. Presumably they’ll hear about ad technology and search, and some new developments for the home page and email. The home page may become even more of an aggregation tool, and add more social media. Yet Yahoo of all companies knows that customizing the home page is too much work for all but its most loyal and tech-savvy users. Historically, it’s been done by 20 percent of Yahoo users. Still, Yahoo is good at personalization without necessarily needing explicit user input, so maybe we’ll see more of that. It better not de-emphasize the prime ad inventory on the home page – that’s one of the few mass-reach premium-value spots online. Search is supposedly front and center. I outline what Yahoo could do there in my Weekly Update.
