Most webmasters chose to use Google Analytics to gain insight on their site’s traffic. Let’s face it, GA is ana mazing product, and it’s free! (Thanks Google!).
Now that being said GA is a powerful tool, it offer many options, tools and reports and you could probably teach a masters just on how to use all of them properly. Because reading your analytics wrong could be just as bad, if not worse, as not having any analytics at all.
For that reason we recommend you pick a few reports and focus on tracking those over time, making any changes on your site and going back to those same reports to decide whether the changes were positive or not.
One of the most common mistakes that webmasters do and that can really through off your data is tracking your own traffic on the traffic from those working for you. These users will spend hours on your site and navigate deeply into it, increasing your measurements, especially if your traffic is relatively low.
There are a number of ways you can avoid tracking your own traffic and the one from those who work for you, IP filtering, etc. but those aren’t 100% reliable.
Fortunately for WordPress users there are plugins like “Google Analytics by Users and Roles” which will not only allow you to place your GA tracking code on all your pages properly but will also give you the ability not to track any hand-picked user or users with a specific role (for instance you may chose not to track admins and authors).
The user interface of this plugin is really simple and easy to understand, it won’t overwhelm you with endless features and options, it goes straight to the point and it gets the job done!
