Why move tracking to the server
Browser-based tags are increasingly blocked, capped, or stripped of cookies, so client-side measurement leaks. Sending events server-to-server, through Meta's Conversions API or a server-side tag container for Google, recovers events the browser would have dropped and gives you more control over the data you share.
Not a replacement, a partner
The common pattern is to run client-side and server-side together with deduplication, so each event is counted once. Server-side is what keeps a pixel-driven audience and Smart Bidding well fed as browser restrictions, ad blockers and consent refusals strip client-side signal, and it works alongside Consent Mode, not instead of it.
Common questions
What is the difference between client-side and server-side tracking?
Client-side tags fire in the user's browser and are exposed to blockers and cookie limits. Server-side sends events from your server, which is more reliable but needs careful setup and deduplication.
Is server-side tracking the same as the Conversions API?
The Conversions API is Meta's server-side method. Google uses a server-side tag container. Both are forms of server-side tracking with the same goal: resilient measurement.
