We have a feature called STATS wherein you can check how may people actually visit your website, with the number given you can formulate which pages or ads are converting leads into sales.
Here are the steps on how to enable your STATS settings:
1. Go to ACCOUNT SETTINGS
2. Click on MAD SCIENTIST ONLY
3. Turn ON the BUILT-IN TRACKING feature
4. Click on OK
5. Refresh your page
When you're done, you can go back to your funnel and you'll see the STATS button on the top right hand corner of your account. Once you click that button, the icons for the pages will change to numerical values equivalent to the number of unique visits to the page.
