When leveraging the ‘Tracked page view event’ trigger, be sure to only apply your actions to events that contain a lead ID greater than 0 and set defer processing to off.
All page view events will be tracked, but most likely we are only going to want to create automated rules for leads that we are tracking. Untracked leads will have their lead_id key set to zero so we will not want to apply rules to events where the lead_id is set to zero.
Because page view events will be the most abundant event occurring on your website, you will not want to defer processing to the cronjob system. This could cause our cron processor component to bog down and stress your site’s resources. Page tracking events are fired via AJAX and in the background, so we should be able to process them immediately without adding too much additional stress to your WordPress environment.
