Facebook, in recent months, has been building up its local page review interface. Now, review scores are highlighted in bright blue in more places and people can click through and sort reviews based on star rating, most helpful and most recent.
According to Inside Facebook reader Matteo Gamba, there are now four CTA for users to place a review or see reviews.
The reviews seem to have taken a page from Yelp, allowing users to sort by most recent and most helpful (apparently ranked by the amount of engagement on the review).
The review scores are now highlighted in bright blue, both all over the page, as well as in sidebar posts. However, on mobile, the only option for reviews appears to be the most helpful option.
