Our bounce rate just got much lower, which we know isn't due to our brilliant content. Seems that we're firing a direct call rule when the user leaves a page (this gives us the scroll depth, time on page, etc... for the user, which is then used to determine the quality of the story in question). Anyway, I'm pretty sure this is what's causing the issue because I can see an uptick in this type of content around the same time. Is there anyway to tell Adobe that this is a "non-interaction" event?
If your Direct Call is triggering on the page then it would definitely increment your Analytics Server Call in which case even if a user was leaving the page with no interaction, a bounce would not be considered since you would have two calls. Now, you would want to move try and changing to another rule type like event based which would not trigger any server calls but would record your scroll depth values into an evar which would be recorded on the next page load.
