SAN FRANCISCO: Yahoo is deepening its connections with Facebook's online social network.

The latest bond announced on late Tuesday will enable Facebook users to share more of their activities on Yahoo's websites, including which stories they are reading.

Yahoo Incorporation introduced the Facebook-sharing option in its main new section three months ago.

The same feature will now be available in 26 other parts of Yahoo's site, including its ''omg'' service for entertainment news and sections devoted to television, movies and games.

By tying more of its services to Facebook's popularity, Yahoo is hoping to give people more reasons to visit and stick around its website.

Yahoo ultimately wants to sell more online advertising.

That's an area where Facebook has been gaining ground as its website has emerged as a top Internet hangout.
