The main 'Publication' tab in your statistics covers the following areas:
Visits – The number of visits made across all devices, including via desktop and laptop computers, smartphones and tablets including repeat visitors, graphed versus the date visited. Note that Zmags determines a 'visit' by browser session, meaning all activity within the same session counts as one visit.
Latest visit – The date your publication was last viewed.
Visits – The total of all visits.
Bounce visits – Percentage of visits that open and directly close the Zmag without viewing another page.

Zoom clicks – The total number of times readers zoomed in while reading.
Time spent in zoom – Total period of time readers spent zoomed in.
Unique visitors – The total number of visits, not counting those times a visitor came back while a "recently visited" cookie was currently active on their machine.
Search Engine traffic – Percentage of readers who came in from a search engine, as opposed to some other source.
