Q: My event parameter values are collapsing into '(other)' — how do I stop it?

Q: My event parameter values are collapsing into '(other)' — how do I stop it?

A: You've hit high-cardinality limits. GA4 caps unique dimension values in standard reports and buckets the rest.
— Standard reports keep a daily limit of distinct values per dimension; everything beyond rolls into '(other)'.
— Common cause: stuffing unique IDs, full URLs with query strings, or timestamps into a parameter.
— Fix at source — strip query strings, group values into ranges/categories before sending.

To see ungrouped data, query it in an Exploration (no '(other)' collapse) or use BigQuery export for raw event-level values.

TL;DR: Reduce unique values at collection; use Explorations/BigQuery for raw detail.
