PLUGIN INTEGRATION
In order to see advanced optionsyou have to click/activate the form opt-in /subscription / lead
Here you have several options, most of them are just about "looks" of the pop-up you about to create. Such as where your submit buttons will show and the text and background color. I will leave this for you to explore.
Paste your Rainmaker code where it says "add form embed code" and you set to go.
LAST BUT NOT LEAST, THE DISPLAY RULES
On this panel you can configure where and how your campaigns or messages will appear. It's very much self explanatory.
You can choose for your messages or campaigns to appear site wide, exclude some pages or choose to appear only on selected pages. You can also choose when they appear.
One thing I do suggest is to turn off your popup campaigns and messages on mobile devices since last update, google is penalizing websites that have popups covering more that x% of the screen.
