Siroko, is an activewear company based in the north of Spain that focuses on producing premium cycling and winter sports clothing. With a strong presence in Spain, Germany, Austria and an expanding footprint in the USA, Siroko is dedicated to providing comfort and timeless style for active lifestyles.

As Siroko continued to scale and expand into new markets, they struggled with the limited visibility of last-click attribution. With Fospha’s full-funnel view of their marketing efforts, Siroko was able to optimize their campaigns in the German and Austrian markets, scaling TikTok advertising for their Spring Sale, driving an efficient revenue uplift.

Here is how they did it:

Looking Beyond Clicks: Unveiling the True Impact of Paid Social

Before Fospha, Siroko relied on Last Click attribution and ad platform data, but this approach was both time-consuming and gave an incomplete view of their attribution.

At the end of March 2024, Siroko onboarded with Fospha and immediately began optimizing their channel mix and campaigns using the year-over-year data that Fospha provides from day one.

Fospha's data revealed that Last Click had been substantially underreporting the value of Siroko’s Paid Social channels while over-attributing to channels like Paid Search. 

Fospha’s modeling, which takes into account aggregated impressions, clicks, and third-party data, showed that Paid Social had actually driven 3.4 times more conversions in 2023 than Last Click reported.

The numbers were even more striking for TikTok, with Fospha attributing 9.5X more conversions to TikTok than Last Click attribution identified.

 Spring Sale Success with TikTok

Equipped with a full-funnel view of their attribution, Siroko could easily identify a group of underperforming campaigns in their Germany and Austrian market (largely in Google channels) and reallocated this budget to Spring Sale campaigns in TikTok, where Fospha showed huge potential.

Replacing these underperforming campaigns, in April, Siroko started scaling up their TikTok presence in Germany & Austria, with channel spend doubling between Q1 and Q2.

The returns were impressive. At the end of Q2 TikTok revenue was up a striking 177%, with ROAS sitting at more than double Siroko’s target.

The impact of this channel mix optimization can also be seen at a blended level with total conversions up 44% in Q2 compared to Q1 2024. 


TikTok also proved its scalability, with Siroko finding the channel performed optimally at higher levels of spend, as the cost of acquiring customers improved by 30%.

This strong efficiency was also reflected at blended level, where ROAS improved by 10% and CPA by 15% by Q2 2024.

By moving beyond the limitations of Last Click, Siroko uncovered huge untapped potential in their impressions-based channels, especially on TikTok. This shift allowed them to make informed decisions about how to optimally invest their Spring Sale marketing budgets. 

As Siroko continues to leverage Fospha for data-driven growth, we can’t wait to see what they achieve next, especially as they expand their reach in the US market.
