Higher EMQ means more events successfully attributed and a stronger signal for the algorithm, so optimizing match quality is how you realize the value of CAPI rather than sending events that arrive but cannot be tied to users and therefore do little. ## How to improve it EMQ improves by sending more and better-quality matching parameters with each event, hashed identifiers like email, phone, name, and other customer information where available and consented, formatted correctly so Meta can match them. The practical work is ensuring your systems actually capture and pass these parameters reliably (many implementations send too few, capping match quality and wasting the CAPI investment), formatting and hashing them per Meta's requirements, and doing so within privacy and consent rules. Because match quality directly gates how much of your conversion signal is usable, improving EMQ is often the highest-return fix in a CAPI setup that is technically sending events but underperforming because too few of them match. ## The discipline The disciplined approach treats event match quality as a key lever in CAPI performance, sending as many correctly-formatted, consented matching parameters as available so events actually attribute, and monitoring EMQ to find and fix where weak matching is capping the signal. Optimize matching, not just event volume. The trap is implementing CAPI, seeing events arrive, and assuming the job is done while poor match quality means much of the signal is unusable, quietly limiting attribution and optimization; the discipline is maximizing the quality and completeness of matching data within consent rules, because Meta can only attribute and optimize on the events it can match to users, and event match quality is precisely what determines how much of your hard-won server-side signal actually counts. ### Related terms
