Track CTR

Hi there! Thanks for your post. 

1. CTR between any 2 pages
   • You could measure CTRs in Amplitude using funnels, with one event being "page view", and the second event being "click button xyz." You can read more about Funnels in our Help Center here.
2. Conversion at checkout
   • To measure conversion at check out, you can create another funnel that has the last step as the purchase event, like in this example here. 
3. Impressions of a product on a page

   • Page View is not a default event within Amplitude so you would have to instrument this on your end. As far as calling the logEvent function with the JS SDK, for example, you would need to call logEvent after event instances that you'd like to track:

     • amplitude.getInstance().logEvent('EVENT_TYPE');

   • You can also view our Data Taxonomy Playbook to gain an understanding of Page View events.

4. Profit generated
   • To learn more about tracking Revenue events in Amplitude, please visit this article on sending Revenue Events. All Revenue events that send revenue as revenue properties will appear in the Revenue LTV chart. Here is an example from our Demo here. 

Hope that helps! Please let us know if you have any follow up questions.
