Unique LP and External web page visits

We are trying to pull out the unique web page visits for a landing page for the last 90 days (as per my understanding the page visit activity are only retained for 90 days so we cant get the data prior to that anyways) but I'm unable to get that from the landing pages or the lp performance report, both are showing the total views and not unique views.. Also we have a Marketo form on the external webpage(with Munchkin ID) so would like to get the uniques visits for that page too so I created a webpage activity report for the same just confirming to get the total visits we need to select each source (known as well as Anonymous visitors (including and not including ISPs) and then add the total count from all three activity source in the set up? And this will be unique we page visits I guess?
