Hi, You can use statcounter I like it most because its visual graphics chart or graph is easy to understand in just one go as well as you can check every thing regarding traffic like other stats. Also you can take sheets for your offline research.....
I use Google Analytics on all my sites. On my Drupal sites I also use the internal Stats tracking and on my Wordpress i also use WPUserOnline.
Been using opentracker for all my sites, you can get a 4 week trial for new users after that its 25.00 a month.
Why would you pay so much/month if you can use something free like Google Analytics? is it better than analytics?
