I ran into a Reporting limitation with a report in which I wanted to add a trend line to column bar chart displaying SEO leads generated Month over Month. The trend line was intended to reflect the # of SEO leads who then converted to lifecycle stage = Customer. I have been told that the limitation is that HubSpot is only able to display the total amount of contacts who are customers as of now, thus a straight and stagnant line, not a trend line.
I think this would be extremely helpful for businesses to be able to pull this kind of information into reports to display quality vs quantity of leads generated.
