Keeping positive ROAS during experiments (Return On Ads Spend) (15+)



Standart Shopping campaigns 

A shopping campaign is our main channel for revenue generation. We spent more than 80% of the whole ad budget. The main challenge for us was how to correctly manage store with over 30k items. Firstly, we divided it based on the website collection, but it is not working. After that we decided to split them based on cost per click, we started getting conversions, but the target ROAS was not reached.


Smart Shopping campaigns 

After almost 10 different structures for standard shopping campaigns, we got some conversion data and decided to test some smart shopping campaigns. This moment changes everything. The main disadvantage of this type of campaign is that we can not check the search term report, we even can’t see any terms where our ads showed. But, it does not matter if it gives you results:) 

We split whole campaigns into three big parts:

  • Amazon best sellers 
  • Website best sellers 
  • All other products 

One very important thing is that for whole smart campaigns we recommend using target ROAS because, without it, google will spend a huge budget without any successful results.


Free listing

This feature allows people to see product results from your store on various Google surfaces, including Google Images, the Shopping tab, Google Search, and Google Lens (availability of listing types varies by country). Just as we don’t charge sites to be part of the Google Search index, participating merchants are eligible to appear in free listings.


Buy on Google 

Retailers of all sizes can sell their products directly on Google, with zero Google commission fees, through our Buy on Google checkout experience. Retailers can work with their own third-party providers, starting with PayPal, for payment processing and more. 


Price competitiveness report

The price competitiveness report shows how other retailers are pricing the same products that you sell. You’ll see an average price for each product, which can help you understand the price at which other retailers are successfully attracting clicks, as well as aggregate metrics on benchmark prices over time.


Other campaigns 

We were using a DSA (dynamic search ads) campaign with low bids, to get some relevant traffic for a really low price. This campaign is useful for websites with a big number of pages.
