I installed WordPress Popular Posts plugin (version 2.3.5, with param "Views logging behavior, log views from: visitors only") there several months. I posted an post there 3 days.
Number of views of WordPress Popular Posts plugin for this post : 35 views (35 pageviews in wp_popularpostsdata table 5 and pageviews in wp_popularpostsdatacache table).
Number of views in Google Analytics for this post : 934 vues (934 visitors and 769 unique visitors).
Why are there so big a difference between the plugin and Google Analytics ?
