Is it though? Without products there are no sales at all. A compelling enough product will sell with no marketing/sales effort, so sales is really only whatever that baseline is + (extra units sold from sales and marketing efforts - cost of sales of marketing). I would think this is actually quite hard to measure, you also have to normalize against many external market factors and behavior of competitors.

would it? maybe you are talking about video games and a good enough game would sell itself. But for other businesses sales / marketing / ads do matter. Imagine you provide a 50% better service than your competitors, but you target audience never reaches your page because they are bombarded with google ads of your competitors
