You can configure several options of the Web Analytics module in Site Manager -> Settings -> Web Analytics dialog:
| Enable web analytics | If true, web analytics module logs the events. | 
| Exclude search engines | Indicates if search engine robots should be excluded from tracking. | 
| Excluded URLs | URLs of your web sites that will not be tracked. All underlying pages will not be tracked either. You can specify multiple URLs (or site sections) separated with a semicolon (;). | 
| Excluded file extensions | Types of files managed by Kentico CMS that will not be tracked and shown in the File downloads report. You can use several extensions separated with a semicolon (;) (e.g. ‘.jpg;.gif’) Please note: it's necessary to include the dot in the extension name. | 
| Excluded IP addresses | Client IP addresses whose access will not be tracked by the analytics module separated with a semicolon (;). You can use it to exclude your own IP address so that your visits do not influence the results. Please note that you can use * in IP addresses as the wildcard character that stands for any digit. | 
| Remember visitors by IP (minutes) | If the entered value is higher than 0, the visitors' IP addresses are used for smarter visits logging. IP addresses are stored in memory for the specified amount of time. | 
| Track browser types | Enables browser types tracking. | 
| Track campaigns | Enables campaigns tracking. | 
| Campaign tracking URL parameter | URL parameter name to identify the campaign. | 
| Track conversions | Enables conversions tracking. | 
| Track countries | Enables countries tracking. | 
| Track file downloads | Enables file downloads tracking. | 
| Track invalid pages | Enables invalid pages tracking. | 
| Track page views | Enables page views tracking. | 
| Track referrals | Enables referrals tracking. | 
| Track visits | Enables visits tracking. | 
| Track registered users | Enables registered users tracking. | 
Please note: These options are applied at the moment when the event occurs. Later change will modify only future events.
