Recolt datas by post with post_meta and display it with the Api Google chart on each post and page in your administration. 2 pages admin exists for home page and by categories in dashboard > statistics menu. These pages work with simple addition of post_meta and only directly displaying in administration (no recolted datas for home page and categories on front end).
If you don’t view the meta box under each post and page, open one post and one page and in the top-right corner hit „screen options“. Select the meta boxes from the plugin.
In the futur, maybe the plugin creates some humanized and dynamics things (like – by user – „your prefered categories“,…) because the plugin recolts datas to make that. Also cron task to create survey by post/by page to make comparison. Also one option for adding personal referers. Some manual and automatic resetting option. Some of this kind of build is already under construction.
The plugin have an option to decrease request by user like 1/2 or 1/5 or 1/10 users, etc…
