The pain

## What *keeps you up at night.*

The real problems we hear again and again. If two or more ring true, SealMetrics fits.

### GA4 adds ~146 KB to every page

Our tracker is ~132× lighter on the wire. CLS stays low, Lighthouse scores don't get punished, your dev team doesn't complain.

### Consent Mode v2 is a maze

Modeled conversions, modelled pageviews, modelled everything. Marketing makes decisions on data you can't audit. SealMetrics captures the real events.

### GA4 + server-side GTM = 3 months of work

We do what server-side GTM tries to do — but out of the box. No GCP project, no Cloud Run, no maintenance.

### BigQuery sampling above threshold

GA4 exports sampled data to BigQuery above certain volumes. Our export is full resolution — every event, no sampling, ever.
