For the business to be profitable, the returns from our ad campaigns had to be very high.

Being new, the client's website had few visitors. we needed to change that.

The Challenge

As we've already mentioned, we started from pretty much zero. Although they were rather successful on Amazon, Corebuy's own website was newborn and unknown when we started working with them.

We had to bring them traffic and sales.

The Strategy

With Corebuy being an eCommerce retailer, it was an obvious choice to focus on Shopping campaigns first. We worked with their product feeds and bids to get the best results possible.

For testing purposes, we also implemented a DSA (dynamic search ads) campaign.

Aside from that, we also launched a brand campaign targeting the client's brand name.

The Results

1. Standard Shopping campaigns

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

2. 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 changed everything.

We split whole campaigns into three big parts:

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

One very important thing is that for all smart campaigns, we recommend using the target ROAS bidding strategy. Without it, Google will spend a huge budget without any successful results.

3. 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).

You can easily set it up here, at Merchant Center:

At Google Analytics, it will show up like google/product_sync. And due to a huge number of products, this channel ended up being in the top 3 for lifetime revenue.

4. Other campaigns

As we mentioned before, Shopping campaigns spent over 80% of the whole budget, so we did not spend a lot on search, display, and other types of campaigns. We used a DSA (dynamic search ads) campaign with really low bids to get some cheap relevant traffic.

A brand campaign was also implemented. It is a campaign where we use only store namingю It is very important to have Search impression Share 100% here, so we used the Target SIS bid strategy here.

As for the other tests, we have launched some search campaigns based on best-performing products. However, they never delivered any positive results for us, so we decided to keep growing shopping campaigns instead.

We also tried Display campaigns. They delivered a big number of clicks, but the average session duration for them was lower than 20 seconds. This traffic was not as relevant as we hoped it would be.

5. Product feed

The website of this store was built on Shopify, so we had a lot of possibilities to create the best-optimized feed.

Firstly, we started with the default API from the Google Shopify App. The main benefit is that it is free and easy to use. However, you don't have any opportunities to customize it and can only use fields that Google can parse from your website. We encountered a really big problem with it - the listed price for each product included a delivery fee in it, even when the shipping was free. In this case, our products become 20% more expensive.

After that, we tried WakeUp data. It is a more advanced tool, but also quite heavy on the budget. We used it for the top 2k website products and did not get any positive results.

Finally, we settled on using the Socialhead app. It is very affordable and easy to use. We paid 50 dollars monthly for the management of over 30k products, which is a really good price. Moreover, Socialhead allows you to add different additional fields like product color, size, weight, etc, and add custom labels, which will help you to manage the store a lot easier!
