Downloadable heatmap visualisation of best time of day and week

Take a look at this powerful visualisation. It uses a combination of Google Analytics Custom Reports and Excel's Conditional Formatting to make the hotspots really stand out.

The example shows conversion rate. But you could choose revenue, or goals, or whatever else you wish.

The article contains links to download the GA Custom Report and the Excel template.

Really good stuff:
