- Leaving out Google Analytics tracking code on some pages of your site – this is easily done, and easily fixed. You simply cut and paste tracking code into the pages you are missing it from. Some bigger sites that are more commercial make it a little harder to fix this issue but should be able to offer assistance should you need it.
- Not customising your tracking code for many domains – this can mean that data accuracy is not at its highest level so ensure that domains and sub-domains are customised for the optimal ROI from your analytics campaign.·
- Traffic from within your business is counted – employees and your existing service providers are not people that you want to be tracking on your website as they are not potential customers. It is possible to exclude IP addresses from your IP range so do this for employees and whoever else you feel you need to.
The most accurate way to learn about your analytics data is to have two profiles with the same settings, then when a change needs to be tested, only conduct the change on one account to see what happens. You can then compare the data to learn if it had a negative or positive effect on your campaign.
