Google Ads (AdWords) campaign target

To reduce the cost per conversion of shopping campaigns compared to the previous year and to make search campaigns profitable. The customer had a profitable business, and they were focused on increasing the margin by reducing the existing cost per conversion in shopping campaigns. The search campaign however wasn't very lucrative due to high cost of acquisition. The customer had to bring down the acquisition cost to less than a quarter of the cost of the product they were selling to render the search campaign profitable.

Problems in the existing campaign setup

  • In the search campaign ads were triggered mostly from broad match keywords. This attracted unwanted clicks which added to the overall cost per conversion.
  • Most of the products were unique and were attracting customers from very different search queries. Since the keywords used were more generic, the ads weren't specific to an individual product.
  • The shopping campaign targeted a lot of products, but most of them were clubbed together into a few product groups. Because available data in product group is an average of high and low selling products, specific high selling products couldn't be targeted.
  • As the number of products offered was large, identifying a product and effectively bidding on it was a hassle. Even Google bid optimizer couldn't get the job done right.
