Measurement, checked every day

With so many websites measuring at once, an error could go unnoticed for weeks.

We built a system that checks every day that events, variables and values arrive as they should.

Result

The status of measurement across all their websites at a glance, with alerts whenever something fails.

What we did

Monitoring dataWe built datasets in BigQuery from GA4 data to check measurement.
Three levels of checksWe check record volume, value format and variable presence.
Every websiteWe apply the same monitoring system across their whole digital ecosystem.
Dashboard with alertsWe designed a Looker Studio dashboard that shows the status of each website and flags any failures.

CONFIDENTIAL CLIENTLarge group · 20+ websites

Faster websites, monitored every day

The SEO team was working on the speed of more than 20 websites, with no reliable way to measure progress.

We built a system that measures real user experience, analyses it every day and alerts the team when something gets worse.

Result

SEO can see how every website is evolving in one place, and spot any drop the next day.

What we did

On-site measurementWe captured Core Web Vitals from every real visit: loading, responsiveness and stability.
Centralised dataWe brought the data into BigQuery, where we cleaned and organised it.
DashboardsWe built dashboards to analyse by website, page, device or period.
Daily alertsWe set up alerts that flag a website when its performance slips enough to need attention.
