Visits to your own web site by staff members can seriously impact your data accuracy, leading you to draw incorrect conclusions and make poor decisions. Even if the numbers are small they may be concentrated in a specific area of the site and so be a big % of the totals for a site section or page. Not good.
To exclude internal traffic first create a new Profile in GA > Admin.This ensures that any mistakes you make will not affect your existing data sources. Once you have named the new Profile go to the Filters(shown) tab and select `+newFilter`. Leave `Create New Filter` radio button Selected. The easiest way to exclude is to select `Predefined filter`. Select as appropriate from the options in the dropdown menus and enter the IP address for your organisation and hit `save`. These days GA updates frequently so within hours you will see how the filter is working.
An alternative, giving you more flexibility is to select `Custom Filter`. Once you have selected that you can then select the radio button for `Exclude`. Once selected go to the`Filter Field` and select `Audience/Users` the drop down menu. As you can see from the image there are now 3 ways that you can exclude incoming traffic from you and/or your organisation.
Again, if you have them for your organisation, the `IP Address` range is probaly the best way to go. Simply enter the IP numbers – taking care to escape out the full stops by using a `\`eg 176\.168\.1\.1. You will find this tool useful plus more info on excluding internal traffic.
Alternative ways to exclude traffic are by using – `ISP Domain` and `ISP Organisation`. If you have one you can find your own `ISP Organisation` if you look in GA >Audiences > Technology> Network. Here you will see the names of service providers used by people visiting your site. If you see your organisations name you can use that in the Filter Field `ISP Organisation` and so exclude visits. Similarly you can add any ISP domain. Over time you can then compare the visitor data in this new Profile with your existing ( unfiltered) Profile and you should begin to see differences in the numbers reported.
One thing to note that is that these techniques will generally not be usable if you work from home and want to exclude your visits.The reason is that most service providers eg BT, Sky Etc use dynamic IP allocation so that each time you log on you are allocated a fresh ( to you) IP address. If you want to exclude visits from your home machine you will need to use the `cookie method` or your can use a browser where you have explicitly set it not to accept any cookies.
