The Okiano service is concerned with creating the Google Ads, assigning relevant keywords that will invoke these Ads when users search for your products. The cost per click is paid by you to Google Directly through your payment means in Google Ads.
A $750 is considered minimal amount for an eCommerce webstore as conversion rate can be between 1% and 4% of visitors for a good campaign, meaning that with an average click cost of around $1.0 you would like to spend a minimum of $25 per day to bring around 25 potential customers to your store in hope to make sales.
