I have 200+ web sites that I track, at present I am dividing them up and running 4 installations of Piwik, but even then I have web sites that are in mixed groups.
It would be good to be able to list sites in groups rather than All Websites
I also second this. Would be a great feature to have. In the meantime, does anyone have a workaround solution, to report data grouped by websites? We want to categorize the websites we manage and display reports by category.
We’ve just released a new plugin which could really helpful to you: Roll-Up Reporting aggregates data from multiple websites, mobile apps and shops into a Roll-Up site to gain new insights and save time.
Roll-Up ReportingRoll-Up Reporting lets you aggregate data from multiple websites and apps into one single site. It lets you answer questions like “How many visits happened on all of my websites and apps?” and “Which campaigns contributed the most across several of my websites?” or “How do my various Brands overall compare with each other?” When you have several shops (eg white-labels) it is very valuable to see how your ecommerce shops are performing overall. Or when you are a web agency and you are serving many customers and want to provide each customer with a single aggregate view of all their web properties. Roll-Up Reporting lets you analyze this aggregated data in one site so easily. It saves you lots of time and helps you gain the insights you need instantly.
