Yotru also lets users see their friends’ purchases from your site, ask their friends questions about your site, browse recommendations and write recommendations about your site to their friends, too. Users can do all of this without leaving your site, just by using the Yotru widget. What’s in it for you?
<ul>
<li>Your site’s visitors feel more confident in your services, because they trust their friends—they will be able to make purchasing decisions much more easily.</li>
