Q: How do I add Leadsius tracking script in Wordpress?
A: What you need to do, is to add Leadsius tracking script before the ending /body tag in Wordpress. The easiest way to do it, is to add a plugin that allows you to do this.
We've used a plugin called "Head, Footer and Post Injections":
After the plugin has been installed, you'll inside the plugin settings find a field named "Before the </body> closing tag (footer)" where you paste your Leadsius tracking script. You find your tracking script in Settings -> Tracking script inside Leadsius.
