Track That Stat

The simple answer is no. Track That Stat was built to be fast and effcient.

The plugin was written in order to avoid high loads on the server. Instead of triggering processes multiple times in one occurrence, then script will only trigger each process after 50 seconds. So this lowers the load on the server as well as CPU. Most scripts will trigger the server every 1-3 seconds. So this creates many processes on the server and it will cause you to get suspended for using up too many resources.

Google analytics is a great tool and is very detailed. The only downside is that all of the information within google analytics is tracked by Google. Google sees all of your traffic, referring links etc. With this plugin, it is hosted on your self hosted WP installation. So you are the only one with access to that information. Some people may not want Google to know everything about the methods they are using to promote their sites. Another advantage is having all of your statistics in one place when you log into your blogs.

All of your data is stored internally on your server. I do not have any access to this information. I guarantee that I do not track anything on your blogs. Not only would that be unethical but I am pretty sure wordpress.org would not let me upload the plugin to their directory if this was the case.

The database size would depend on the actual data that is being collecting so there is no set number. If all of your traffic comes from referring sites, then it would be less than if your traffic came from both search engines and referring sites, which would include keywords data as well.

Simply click on "Settings" within the plugin and enter in your IP address. This will exclude you from being counted. A later update will have the option to not include you at all while you are logged into wp-admin.

The actual "Views" are considered page views. This is one person visiting multiple pages from one IP address. "Unique Visitors" counts one unique visitor from a single IP address.
