Match Boost helps to improve the reach and match rates of your audiences by enriching them with third-party user data before they are sent to downstream paid media partners. By using Match Boost to enrich your audiences, you can increase the return on ad spend (ROAS) of your marketing campaigns.
\nThe following outputs support Match Boost:
\nCurrently, audiences can only be boosted using US-based third-party data.
\nMatch Boost can be used with the following audience types:
\nBoth audience types can be enriched with Match Boost to improve match rates when forwarded to supported downstream platforms.
\nMatch Boost can be enabled either at the level of a single audience connection or an entire output configuration. If you enable Match Boost for a specific audience connection, only that connection will be boosted, regardless of how many other audiences are connected to the same output. You can turn on Match Boost for up to 4 individual audience connections.
\nIf you enable Match Boost for an entire output configuration, then every audience connected to that output will be boosted, assuming they meet the User identity requirements.
\n\n\nTo boost an audience connection, all supported identifiers for the connection must be forwarded.
\nIf you disable any identifiers in the audience connection settings, Match Boost cannot be enabled.
\nThis requirement prevents Match Boost from adding identifiers that you have intentionally excluded for compliance or privacy reasons. For example, if you exclude IDFAs from an audience for compliance reasons, Match Boost will be unavailable for that connection.
\n\nYou can turn on Match Boost while creating a new audience connection:

\n\nFor existing connections, the Connect tab of the Audience Builder is the only place to enable Match Boost:
\n![](\"/images/guides/segmentation/match-boost/3-boost-button-connect-tab.png\")
\nAudience connections with Match Boost turned on are labeled with a Boosted button:
\n![](\"/images/guides/segmentation/match-boost/4-boosted-icon-connect-tab.png\"){kind=icon}
\nYou can also start from the Audience Group Editor: click the Boost/Boosted button on the audience card to open the Connect tab, then click the Boost button next to the connection and select Match Boost or Household Reach.

\nTo enable Match Boost for every audience that is connected to a specific output configuration, you can enable Match Boost in the output configuration’s settings:
\n\nNavigate to the output configuration’s settings:
\n![](\"/images/guides/segmentation/match-boost/bulk-boost.png\")
\nYou can disable Match Boost for an output configuration at any time by returning to its configuration settings and unchecking Match Boost. This disables Match Boost for all audiences connected to that specific output configuration.
\nTo disable, or “unboost”, Match Boost for an existing connection, use the Connect tab of the Audience Builder:
\n![](\"/images/guides/segmentation/match-boost/unboost-audience-builder.png\")
\nYou can also start from the Audience Group Editor: click the Boosted button on the audience card to open the Connect tab, then click the Boosted button next to the connection and uncheck Match Boost.
\nTo turn off Match Boost for every audience connected to an output, see Enable Match Boost for an output configuration.
\nYou can use Audience Insights to review the impact of Match Boost on your audiences, including changes in reach over time and the number and types of identifiers added through enrichment. For more information, see Benchmarking in Audience Insights.

Match Boost improves match rates through a process called identity enrichment. In practice, this means temporarily supplementing the profiles in your audience with additional identifiers and attributes from a trusted third-party provider.
\nBy broadening the set of data associated with each user, downstream platforms can perform multi-key matching, which increases the ability of recognizing your audience members.
\nMatch Boost begins with the first-party data already present in your mParticle audiences, such as:
\nThis data is then expanded through cascading enrichment, where each known identifier can resolve to additional identifiers and related attributes in a third-party identity graph.
\nOnce identifiers are resolved, associated user attributes may also be added. These may include first and last name, gender, city, state, and postal code, depending on the specific output your audience is connected to.
\nAttributes strengthen matching in platforms like Meta (Facebook) Custom Audiences, which use both identifiers and demographic attributes as part of their multi-key matching process.
\n\nAudiences connected to The Trade Desk are enriched differently, since the goal is to generate Unified ID 2.0 (UID2) values rather than to add raw identifiers and attributes directly to the outgoing profile.
\nAs with other outputs, Match Boost starts from the first-party data already present in the audience being boosted, and uses it to find additional identifiers and attributes from a trusted third-party provider. For The Trade Desk, these additional identifiers and attributes are then used to generate UID2s, which are added to the profiles forwarded to The Trade Desk, extending UID2 coverage beyond what your first-party data alone would support.
\n\nIn keeping with mParticle’s privacy policy (and to comply with contractual agreements between mParticle, third-party data providers, and downstream partners), no enriched data (identifiers or attributes) is exposed to customers.
\nNo first-party data from mParticle is shared with the third-party provider, and no third-party data is added to user profiles within mParticle.
\nYes, Match Boost is fully compatible with Composable Audiences. The enrichment process works the same way for both Real-Time Audiences and Composable Audiences, adding third-party identifiers and attributes before forwarding the audience to downstream platforms.
\nAfter you enable Match Boost and connect an audience, enrichment occurs prior to the audience being forwarded to your chosen output. However, the time it takes for change in your match rate to appear depends on the downstream platform:
\nNo, Match Boost adds any available user data from the third-party provider that’s missing from your audience.
