Overview of Different Types of Filters

Google Analytics provides you with three predefined filter types and several customized filters.

Filter Name Explanation
Exclude all traffic from a domain Excludes traffic from a domain that you specify. Applies reverse lookup and can filter out traffic from an ISP or the company's internal network.
Exclude all traffic from an IP address Excludes traffic from a single IP address or range of IP addresses. Useful in filtering the company's internal traffic.
Include only traffic to a subdirectory Includes only those visitors who are viewing a particular subdirectory on your web site. Useful in tracking a particular section of a web site e.g. www.yoursite.com/customercare.

Understanding Best Practices for Setting Filters

Always keep the default profile without applying any filters.

Adding more than one include filter to a profile can cause data to not appear in your reports e.g. if you use include filters to only include certain IP addresses, then traffic from all other IP addresses will be ignored.

Filters are executed sequentially in the order they are listed in your settings. Thus, output from one filter serves as input for the next filter. Thus, it is important that you apply filters in a correct logical manner.

To setup filters, open up your desired profile, and navigate to the 'wheel' on the top right of your screen. Once you open up all of your settings, you'll see options to add in Filters. See screenshot below.
