For our logged in users we update each page's metrics daily. To make sure you are looking at the latest statistics, open your page in Likealyzer and hit refresh on the top right of the box that shows your Likerank:
Any page with a verified Likerank and/or Competitors in your leaderboard
We refresh these pages every 24h but there is no way to manually force a refresh for these pages.
Pages you are browsing while you are signed in
If you navigate to a page that has not been refreshed in over 24h we'll try to refresh it once you get there, this means the score could change while you are on the page. This will happen within the first couple of seconds of you coming to that page.
