Bily: Server‑Side Tracking

Bily lowered our CPMs by 13% when we tested it. We're quite impressed. The data seems super accurate after our testing. We had many different convoluted setups in the past and they were clearly dropping conversion and didn't have as many features. Their MCP has been magical too. I didn't realize we could automated so much. We were about to use OneTrust, but then we realized with bily, it's just one toggle for the cookie consent! That was a huge cost saving. Also, Philippe has been very helpful throughout the process

I am very dissapointed. There is a customer service more or less responsive, but the bugs and technical issues make impossible to use the app. I don't recommend.

Since integrating Bily, I’ve noticed a clear improvement in tracking accuracy, especially with the Add-to-Cart event — the matching quality is on a very high level. This has helped my campaigns get more precise data for optimization. The onboarding support was also excellent; the team guided me through the setup and answered all my questions quickly. Really happy with the results so far.

“now I just check Bily, scale the winners, and cut the losers. My only regret? Not finding it sooner.”

Every day I move six figures in ad spend. Every day I fight against BS platform reporting. Every day I trust Bily more than Meta’s ‘trust me bro’ numbers. If you like clean, hard data and making decisions that actually make you money, you need this. If you like spending money on bad ads, keep doing what you’re doing.
