This post is so old, but @a_schumacher 's 2/22 reply gives me hope…Amanda, personally, I would expect a heat map tool to live in the page’s reporting. I think being able to see clicks on negative/empty space would be good (could help us understand where our pages may be misleading), but obviously valid clicks are the main priority.
I can’t think of a need for viewing clicks on an individual basis, but that doesn’t mean others couldn’t make use of that level of granularity. A heat map for individual pages (and landing pages!!!) would be good - not sure that a high level, site-wide overview would be as useful.
I really hope your team is able to make this feature happen! Thanks for all your hard work!
