Optimizely allows you to integrate with various other analytics tools by default. The Analytics Integration options contain out of the box integration with some of the most popular tools. It's also the best place to check which integrations are turned on. By default all the options are disabled. To access the Analytics Integration dialog click on 'Analytics Integration' under the 'Options' button in the Optimizely editor.
By enabling any of the integrations you allow Optimizely to send data to the platform in question. For more information about specific steps for setting up the integration take a look at How to Integrate Optimizely With an Analytics Platform of my Choice.
Enabling the GA integration gives you a couple of options.
- Slot Number - Select a slot number that is not currently being used by another experiment or any custom variables in your existing GA integration. This is the Custom Variable Key that you will use to find your Optimizely experiment in GA.
- Custom Tracker - Only use this if you're defining a custom tracker on your page. If you're not sure what a custom tracker is, leave this blank.
KISSmetrics is turned on for an entire project, so turning it on for one experiment will affect all the experiments in that project. Keep that in mind when turning on KM integration.
SiteCatalyst integration requires a small block of code to be added to the SC implementation on your page. Once enabled it will allow you to look at your SC data split by the Optimizely Experiment and Variation.
You do need to pick either a prop or an eVar that Optimizely can use to send the data. It's not necessary to have both, but one is required.
