We started working with Fospha in 2020 following a period of high growth fueled by very high spend in Facebook. Then we started to worry about market saturation in our Facebook audience – it was getting harder to maintain that growth rate and keep hitting new audiences.
We diversified into lots of new channels, which was working well but made the picture a lot more complex. It made it really hard to understand which channels were playing what role. We didn’t trust the ad platform data, but Google Analytics wasn’t a fair way of measuring our impressions-led channels like Facebook, TikTok and Reddit, which we knew were driving most of our sales.
We were able to calculate a figure for blended customer acquisition cost, but to get that data at a channel level was basically impossible… we were having to make decisions based on gut feel.
Ultimately, even though we knew we needed to spend to grow, this made it hard to justify investing in our top of funnel, and impossible to test whether existing channels and campaigns were over-saturated.
The biggest thing has been giving us a consistent source of truth. Where previously all the ad platforms had been claiming credit using different attribution models, by working with Fospha we were able to do apples and apples comparisons of CACs across our marketing mix. The Fospha model considers clicks, impressions and offline advertising, so we knew everything was factored in. Now I log on every morning to see performance by channel in one place and make informed decisions on day-to-day optimizations.
Their Budget Planner product was also awesome for us. It uses machine learning to tell us how to spend our budget across all our marketing channels for the best possible return – it includes saturation modelling too which is great for us as a big spender. One of the really early results from that was that we immediately cut our monthly Facebook spend in the UK by over 20% without seeing any drop in revenue.
It’s been brilliant. Using Fospha data we successfully scaled our top of funnel, and in the first 6 months of our partnership increased our new customer conversions by 54%. Amazingly, we were able to do this within our target CAC too. During this crucial time Fospha has been the most important tool in our marketing stack.
