Do I need to insert a tracking code to all pages of my website?

No, however, we recommend your team add the tracking code to each page of your website. If that's not possible, we recommend adding it to the homepage and landing pages of your website. It's best practice to ensure you have reports for initial and recurrent visits, the journey they take on your site, and overall engagement time. 

Using the tracking code in this way will give your team access to more intent signals from prospects and the ability to create more precise campaigns through Influ2.
