Setting up a Google Shopping campaign and initial results

The client pays at least $150 on eBay for a buyer. With the help of good old Google Shopping campaigns, the price dropped at least twice! The market is the USA, so the campaign did not work instantly as the first launch was limited not only by the maximum cost per click but also by a rather small daily budget. When the daily budget was raised to $50-60, sales started to go very actively, whereas previously there could be a maximum of two sales per month on the site. And "experts" had already set up pMax for this person, another modern tool, wasting budgets without results! During this period, there were 11 orders. 2 organic, one direct, and the rest were identified as Google Ads. With this number of orders, the client saved at least $1,000 on eBay fees!
