Why Machine Learning Is Only as Good as Your Tracking Data
Facebook Ads lives and dies by machine learning. The platform assigns a quality score, predicts action rates, and auctions your ad—every step powered by the data you feed it. Starve the algorithm and it guesses; feed it clean, complete signals and it prints returns.
How the Algorithm Learns
On‑platform signals — clicks, likes, shares, comments. Each micro‑action teaches the model what hooks attention.
Off‑platform signals — add‑to‑carts, check‑outs, app installs on your site. These events close the feedback loop and tell Facebook which impressions turned into revenue.
If either data stream is missing or noisy, optimisation stalls and CPM rises. That’s why flawless event tracking isn’t optional; it’s the fuel.
Bottom line: Machine learning can’t optimize what it can’t see. Give it the full data picture with Bily and watch ROAS rise week after week.
