I'm sending out a bi-monthly email newsletter that contains different types of article. What I'm trying to calculate is a useful metric for understanding which articles are the most popular, but I need to factor in that they don't appear in equal number, i.e. not every email has the same number of each article type.
I have access to all the data I need, such as number of clicks, number of instances of each article type per email etc. but I'm just struggling with what the calculation should be!
Any help much appreciated.
