On all of the sites I have published, they contain a Google Analytics token. This causes every visit to be logged by Google Analytics. I can grant access to your account on request, it contains a lot of information about how many site visits, which countries did they come from, where did people go, where did they go to next, how long were they on the site for, how did they reach the site etc etc. There are people that specialise in accessing and manipulating Google Analytics data for a living, so there is much much more than most of us need to know.
I have recently come across a plugin called Google Analytics Dashboard for WP that can be configured to connect to my Google Analytics account and pick up the statistics for your website. Once set up, you can login to your site and see a panel on the dashboard that contains a set of configurable views. You can see an example below from Prestwood Village Association website. There are twelve different sets of data presented and different timelines can be selected.
It is one of the most useful plugins I have come across for internal marketing analysis.
If this is something you would like to have available on your site then do the following:
Login, go to Plugins and click on Add New and search for Google Analytics Dashboard for WP. Install it and activate it. Then contact me and I will link it to your GA Account. After I have done that, it is always available everytime you login.
