Instapage adds code per landing page, so you add the Converly code to each page you want tracked.
Step 1: Copy your install code
In Converly, click Install in the left sidebar and copy the code shown at the top. It is unique to your site. See Install Converly for the full walkthrough.
Step 2: Add it to Instapage
Open your page in Instapage and go to its settings, then the HTML/CSS area. Paste your Converly code into the head section, then save and publish. Repeat for every page you want Converly to track.

Check it works
Submit a test entry through a form on your site, then open the Activity page in Converly. If the code is installed correctly, the event shows up there within a moment.
Paste your own code
Any code shown in a screenshot is only an example. Always paste the exact code from your own Install page, which contains the key that is unique to your site.
