The headline, the problem and the solutions are all different things.

- Front end tracking did not lie, the people tracking it were not aware. If opendoor was spending on Ads, the marketing team would be the first to see a disparity between the clicks on an ad network and pageviews on their end.

- As such this is also a reason why you need to check your server hit logs with your Analytics.

- Where is the author is right it Frontend numbers being incorrect largely due to blockers

- His understanding of bounces is also incorrect. Bounce is when there is no second "interaction event", many marketing folks fake-fix the bounce rate, by sending a scroll event as an interaction event.

- I always tell people that analytics numbers are "signals", not "metrics", they are not accurate enough to be called "metrics"
