Having a Fast Shipping badge on your website will drive customer attention and boost conversion. Exactly how much? On average we see around 40% sales conversion lift with badges versus not having badges. That is, about 40% more of your customers, who land on your pages, will end up buying the product.
Fast Tag boost, then, is the extra sales that you got when you showed fast shipping badges on your listings (a subset of all Fast Shipping orders placed through the Fast Tag program). In other words, the sales attributed to the benefit of fast shipping only.
So how exactly is the boost number calculated?
The bold number that you see on the dashboard is the extra sales divided by all sales you would have gotten naturally (the striped green over solid green and blue).
And how is the boost itself calculated?
Sales boost = total sales* - sales occurring naturally = total sales - total sales / (1 + badge conversion lift**)
*all sales and boosts are computed on a market level on a day by day basis
**for the badge conversion lift we are using platform averages, not your specific lift.
