Results overview of our CSS service for 2025

From the perspective of online sales and performance advertising, 2025 can be described as a stable and balanced year. After several dynamic and uncertain years, the market gradually settled, and e-shops increasingly focused on efficiency, budget optimization, and long-term performance sustainability. This approach was clearly reflected in the results of CSS Shopping in EU, where smaller fluctuations between individual periods and consistent performance throughout the year could be observed.

The beginning of the year was naturally influenced by the tail end of the Christmas shopping season. The first quarter was among the stronger periods, with online sales remaining at a high level and e-shops able to work efficiently with existing demand. The second quarter brought a slight slowdown, which is typical for the spring months. Nevertheless, campaign performance remained stable without any significant declines.

The third quarter is traditionally the weakest period of the year, mainly due to the holiday season. The same pattern was observed in 2025; however, the decline was not significant. E-shops managed to keep their advertising active even during the summer months, which had a positive impact on traffic quality and overall campaign performance. The final quarter once again confirmed its importance, as performance returned to higher levels thanks to increased demand during the shopping season.

From a quarterly comparison perspective, it is important to emphasize that the differences between individual periods were not extreme. This suggests that in 2025, e-shops approached campaign management in a more systematic and less impulsive way than in previous years. The focus shifted toward stability, cost control, and output quality rather than short-term volume maximization.

The overall results for 2025 confirm the positive development of performance advertising within CSS Shopping in EU.

An impression volume exceeding 5.3 billion indicates very strong market coverage and a high level of ad visibility across advertising channels. The campaigns were able to generate demand consistently over the long term and maintain a stable presence in both search results and the display network.

The number of clicks, reaching over 94 million, confirms that the ads were sufficiently attractive and relevant to users. A CTR of 1.77% points to a balanced ratio between broad reach and the quality of audience engagement, with the ads effectively capturing attention even at very high impression volumes.

An average CPC of €0.24 indicates efficient cost management and strong execution of auction strategies. Despite increasing competition, the cost per click was kept at a reasonable level, reflecting a well-structured campaign setup, relevant keyword selection, and optimized ad creatives.

A conversion rate of 1.86% suggests a smooth and functional transition between the ad and the landing page. This indicates that users were directed to an environment that matched their expectations in terms of offer, pricing, and overall user experience.

The year 2025 showed that CSS Shopping in EU has reached a phase of stable and predictable performance. Seasonality remains a natural part of e-commerce, but its impact was milder than in previous years. E-shops focused more on traffic quality, efficient budget allocation, and campaign optimization throughout the entire year.

The overall results indicate that well-configured advertising can deliver consistent performance even in periods without major market fluctuations. As such, 2025 confirmed the ongoing shift toward long-term sustainable performance, where success is driven not only by volume, but primarily by business value and campaign efficiency.
