You can install Airgrow automatically via Google Tag Manager, or you can embed the Airgrow tracker code into your site code.
Navigate to your current container and click "Add new tag."
Click "Choose a tag type to begin setup," and in the window that appears on the right click "Custom HTML."
Insert the tracker code in the HTML field, then click "Save." Next click "Choose a trigger to make this tag fire," and select "All pages."
Click "Save" once more, then click "Submit" in the upper right-hand corner of the screen. In the "Version name" field enter the words "Airgrow installation," then click "Publish."
Open your site in a new tab. This will automatically send the first event to the tracker. This completes the installation.
To install manually you will need developer access to your site. Insert the tracker code before the closing tag </head>. The tracker code may be found at this link if you have already registered. If not, first register and you will see it immediately following registration.
