Measurement
Signal loss
The share of conversions and user data that ad platforms can no longer see because of privacy rules, browser limits and consent choices.
What it is
Cookie restrictions, app tracking prompts and consent requirements all remove data that platforms used for targeting and measurement.
Why it matters
For lead generation and e-commerceLess signal means reports undercount and bidding learns from less. Accounts with better data recover more of it.
In practice
Close the gaps with server-side events, enhanced conversions, offline imports and first-party data, all with consent.
A common mistake
Reading a drop in reported conversions as a drop in real ones without checking the CRM or store.
