Explain
When a number moves, Explain breaks the movement down by products, traffic sources and devices, so you see what drove it.
What drove the change
Pick a metric (visitors, conversion, order size or revenue) and a period. Explain compares it with the period before and breaks the change down by products, traffic sources and devices, and by tags when your site uses them.
The result is a waterfall of what pushed the number up and what pulled it down, with the top five contributors in each group.

The impact, calculated
Each contributor's impact is calculated, not guessed. The impact on conversion rate, for example, is the item's conversion rate weighted by its share of sessions, so an item's impact reflects both how much it changed and how much of your traffic it carries.
One item in depth
Open any contributor for its own impact analysis: the current period set against the periods before it, so you can see whether the movement is new or part of a longer trend.
