LinkedIn, whose site is used by about 175 million members worldwide for professional networking, started rolling out the new Profile on Tuesday, and expects to reach everyone in a few months.

"LinkedIn is about connecting talent with opportunity at a massive scale," LinkedIn CEO Jeff Weiner said during a webcast press conference, adding that the Profile is at the center of the site to help members connect.

LinkedIn has tried to make the Profile more visually appealing and thus help members better highlight their professional experience. The new Profile features inline editing, intended to simplify and make more convenient the process of updating information in its different sections.

The Profile will now also make more prominent relevant information about people on members' networks, such as shared interests, to foster increased and better-informed engagement.

Weiner said that the current annual run rate for searches on LinkedIn is 5 billion, and that the motivation behind those queries goes beyond people looking for job opportunities and networking, and includes salespeople scoping out leads, journalists doing reporting and entrepreneurs seeking investors.
