Google announces authorship markup-
Google announced 
this week that it will immediately begin supporting authorship markup, as a way of better connecting authors with content on the web. This change will enable users to search for content via an author's name. The service will also enable websites to publicly link from content to author pages. Othar Hansson explains in his post on Google’s Webmaster Central Blog, “
If an author at The New York Times has written dozens of articles, using this markup, the webmaster can connect these articles with a New York Times author page. An author page describes and identifies the author, and can include things like the author’s bio, photo, articles and other links.”
Google announces embedded format for Ad Sitelinks-

Instead, text in your ad that exactly matches one or more of the sitelinks in your campaign will automatically be linked to that sitelink’s destination URL. With embedded sitelinks, potential customers can pick the part of your ad that applies directly to their current interests and visit the most specific page for that topic.”
