User Story :
Magento 2 Site was loading pages in 6 seconds and the CPC was at 0.07 USD per click.
We optimized the site product detail page and the site load time was reduced to 2.5 seconds.We were surprised to see that the CPC cost went down to 0.05 USD per click.This mean that while we were getting 1400 clicks per 100 usd not we were getting 2000 clicks per 100 USD.Indirectly a saving of 600*0.07 = 42 USD per day or 1260 USD per month.
The other known benefit is higher conversion.Also while we were getting 4 orders from 1400 clicks per day now it was 7 orders from 2000 clicks per day.
So from a cost of 35 USD per order we are not at 28.5 USD per order.
