As patio points out, this won't really affect sales because it doesn't measurably alter the top line (revenue). What it does do (assuming) is modify that bottom line (profit) in a number of ways: 1. Given the same $1M expenditure on product development, nets better results. 2. Free advertising (reducing expenses of that department) with all this indirect marketing. Additionally, a better algorithm helps them to secure their position in the market, which is really more of a strategic move; hard to measure.
