# Free Campaign URL Tools

Use the [UTM Builder](/tools/utm-builder.md) to create campaign URLs with source, medium, campaign, term, and content tags. It preserves existing query parameters and fragments and runs in your browser without signup.

## Check conversion tracking

The Library guides include local [payload checks](/library/meta-capi-missing-duplicate-events.md), [browser identifier checks](/library/fbp-fbc.md), and [event pairing checks](/library/meta-event-id-deduplication.md). For Meta's reported score, read the [Event Match Quality guide](/library/meta-event-match-quality.md).
