Weird Fish has proudly served the United Kingdom and beyond for 28 years and counting with the same founding values at its core. Let’s dive further into what Weird Fish did to be successful with Bloomreach Engagement, how it was achieved, and the impact it had on the company.

The Challenge

Weird Fish wanted to ensure its revenue did not suffer because of the changes to third-party tracking by Safari and Firefox. 

As privacy laws have changed how businesses can conduct themselves online and acquire customer data, questions around keeping the Facebook Ads revenue flowing in have emerged. Weird Fish set out to answer these questions.

The Solution

Bloomreach Engagement offers the perfect solution in this case: Facebook Conversions API (FB CAPI). The FB CAPI integration offers the possibility of sending important events, such as purchases or leads, to Facebook Ads. That in-turn allows for better optimization of Facebook Ad campaigns. 

FB CAPI directly responds to the decreased reliability of the Facebook pixel and offers more control over what data is being sent to Facebook. The API allows companies to send events to Facebook Ads’ platform directly without having to rely on browser pixel tracking. Brands have much more control over what data is shared with Facebook thanks to Facebook Conversions API. 

The Results

The implementation and integration was a success for Weird Fish. In comparing results over a four-month period at the end of January 2021 to the end of May 2021, Weird Fish saw significantly better metrics with Facebook Ad campaigns after using Facebook Conversions API. Those metrics include: 


  • An 82% increase in revenue

  • A 17% increase in impressions

  • A 3% increase in reach
