deciding btwn client-side pixels and a server-to-server setup usually comes down to ur priority between
data accuracy and implementation speed. client-side is easier to deploy via
gtm.js
but relies too much on browser privacy settings and adblockers. server-side setups provide a more
reliable source of truth for attribution by bypassing the browser layer entirely.
>it basically eliminates the impact of ioss privacy restrictionsthe trade-off is that u gotta manage ur own infrastructure and handle
increased cloud computing costs for the proxy server. if u only care abt surface-level metrics, stick to the browser, but if you need precise attribution for roi calculation, the extra work is necessary.
