This discount is not an actual reimbursement of CPC costs, but an advantage in real-time bidding for a specific bidding position against Google CSS. Your ads through a CSS partner
start from a better position, participate in more auctions, and are likely to get more impressions. CSS partners do not have a price advantage over each other.
They also do not have a price advantage in ads from dynamic remarketing, which is part of Smart Shopping Campaigns.
Such a clear impact of CSS, such as cost-per-click reduction, will only be seen in a standard CPC bid shopping campaign. In a smart shopping campaign or a simple but bid-based conversion strategy, the benefit will generally not be fully and specifically represented in reducing the cost-per-click. But a thorough analysis will find it and sum it scattered across various indicators, such as increased volume and number of transactions. Check the results
of our customers who migrated their Shopping ads to Netpeak CSS.
