Social media firm Pluck has developed a new version of its SiteLife platform – the technology currently employed by Hearst Digital and USA Today to ramp up interactive features for users.

According to a press release, the new version (3.3) offers improved search engine optimisation to make content such as comments on news articles and forums more open to search engines.

It also gives more options for publishers when managing online communities.

Pluck’s technology, which handles user comments, ratings, recommendations, image and video sharing, forums, blogs and creates social network-style profiles for users, was recently implemented by the Guardian’s Comment is Free section.
