Facebook is adding a slew of new apps and services to its site in the hopes that visitors never ever leave—or at least extend their stay on the site as long as possible. Some of these—such as new tools for cooking and fashion applications as well as services from Netflix and Spotify–were unveiled last fall.

Now, a number of additional "lifestyle apps" are joining these, for a total of 60. These are provided by such companies as Ticketmaster, Rotten Tomatoes and travel site Gogobot.

The information posted in these apps will also appear on the Timeline.

More Than Just the 60

Marketers will find the information about Facebook users significantly increasing–such as detailed information about their leisure time activities–as more developers build apps for the site. Facebook has opened its platform for all developers, not just the 60 apps that have launched. "Soon, there will be apps for all types of interests, as more apps will launch over time," Facebook’s director of platform Cal Sjogreen wrote in a blog post. "Whether you love snowboarding, gardening, hiking, or knitting, or something else, there will be an app for you."

Timeline's Role

The growing number of apps will also position Timeline as users' de facto online presence—a role Facebook clearly expects Timeline to assume if it hasn’t already.

Facebook Chief Technology Officer Bret Taylor told the LA Times that the new apps would help users personalize their profiles—and that Timeline has deepened users' relationship with Facebook and increased the amount of time they spend on the site.

Already Sticky

The rollout of these apps follow news from TBG Digital that it is 45% cheaper to buy an ad format such as Sponsored Stories or to click a Like button on Facebook compared to traditional online ads that link to the web.
