Period for analysis:

In this case, we compare the results of 2024 and 2025.

Main tasks:

sales and profitability growth in a highly competitive environment

Results for 4 months:
  • Transaction growth: 50,94%
  • Income growth: 41,07%
  • ROAS Growth: 46,9%

Situation in 2024:

Transaction cost: 119.8 UAH

Conversion rate: 3.03%

ROAS: 794%

 

Overall, after achieving stable metrics since launch in January 2023, the goal in early 2024 was to increase transaction volume and improve ROAS as much as possible without changing the budget.

 

A quick note: our list of services does not include things like search query analysis, expanding negative keyword lists, monitoring and analyzing current metrics using provided statistics in Google Ads, Google Analytics, and Google Merchant Center, optimizing RMax signals, adjusting daily campaign budgets based on performance, and other regular work. We only include more or less major changes.

 

 

 

In the spring of 2024, we decided to test a popular RMax strategy of dividing products into "Heroes," "Zombies," "Sidekicks," and "Villains." We divided the overall RMax campaign into four.

Our hypothesis is that dividing the budget into «bestsellers» and «undervalued» products will yield

best result.

The testing lasted more than 2 months.

The result was that segmentation fragmented the data, and Google's algorithms did not have enough data to optimize advertising, which worsened the results.

Therefore, after analyzing the results, we came to the conclusion that it was necessary to return to a single, common RMax campaign, which allowed the system to work with the full volume of information.

 

This summer, we set up enhanced conversion tracking. In short, this feature improves the accuracy of advertising campaign measurement. According to our analysis, this implementation had the biggest impact on improving advertising performance.

 

At the beginning of 2025, we decided to conduct another test: replacing the feed-only ad group with a group of ads containing ad text and banners. Previously, we had seen that displaying ads only in shopping results was more effective, but it's always important to test different hypotheses on different projects, which is what we did.

After two weeks of testing, we already noticed significantly better results in the object group: CTR increased from 1.6% to 1.8% (+14%); ROAS increased from 12,24% to 17,00% (+39%). Therefore, we left only the new group running.

Next, in the RMak campaign, we divided product categories into different groups of objects, which allowed us to target more specific audience signals to specific categories. This didn't result in as significant an improvement in performance as we expected, but we decided to retain this setting primarily for easier management and data analysis.

 

We've made other changes since then, such as narrowing our user base by adjusting geotargeting in the DSA campaign and making some changes to account extensions (objects), but we won't dwell on that.

 

So, at the moment, for 2025, compared to the previous one, we have received the following results:

  • transactions: +50,94%
  • transaction cost = 67.04 UAH: decrease by -44%
  • Conversion rate = 4.04%: increase of +33%
  • Income: +41,07%
  • ROAS = 979%: an increase of +46.9%

Of course, we don’t stop there and continue to work on improving the efficiency of our activities.

Key findings:
  • Data aggregation trumps segmentation. It was confirmed that the algorithms work more efficiently on large data sets.
  • It is important to keep an eye on new features and test them. Guided by this rule, we implemented advanced conversion tracking and have not regretted it.
  • all projects are different. If one setting worked on many projects, it doesn't mean it will work on all of them.
  • regular audit. It is this that allows us to find growth points even when everything seems to be working perfectly.
  • cost optimization. We managed to increase revenue by +41% while reducing costs by -4% by reducing non-targeted traffic and increasing the most relevant traffic.
Result

We not only maintained stable project performance over three years of collaboration, but also found ways to reach new levels of profitability, using the experience of previous setups as a foundation.
