If you want to generate leads but at the same time do not wish to overwhelm your readers with automatically popping out windows, etc, you can create a custom form pop-up.
That means that the reader will see the form in a popup only after clicking on the highlighted area.
To create a custom form popup perform these quick steps:
Open the publication page in Edit mode
Click the Hotspot tool and open the Pop-ups section
Choose the Form option and select the form from the drop-down menu
Once the form is chosen click Add to page button
