Twitter broadened its reach by letting websites add "Follow" buttons that visitors can click to begin tracking posts at the globally popular microblogging service.

Twitter billed the button as "a new way to follow Twitter accounts directly from the websites you visit every day."

The feature was rolled out the same day Web advertising company AdGrok announced it has been bought by San Francisco-based Twitter.

"When Twitter approached us and asked if we'd be interested in working on their monetisation platform, we realized that this was a once-in-a-lifetime opportunity that we just couldn't pass up," AdGrok said in a blog post.

"Starting today, we will be working full-time on Twitter's revenue engineering team."

Websites that took part in the Follow button launch included online venues for pop stars Lady Gaga, Justin Bieber and Britney Spears as well as news, sports, and videos.
