I’m Chris, founder of Net Impression. With over 10 years of experience in analytics and conversion optimisation, I help e-commerce brands, agencies and ambitious teams get their data in order. Google Analytics 4, BigQuery and Tag Manager are all part of the toolkit.
At Net Impression, we don’t just plug in dashboards. We build our entire insights and experimentation stack in-house, which means no reliance on expensive third-party tools. This gives our clients full control, cleaner data, and lower ongoing costs.
We turn messy metrics into clear, strategic insights. Then we test what matters, using custom A/B and multivariate experiments designed to improve conversions, revenue and user experience. When we find what works, we scale it with confidence and build a roadmap for sustainable growth.
OUR Expertise
With Google Analytics 4, we handle every step: data-layer planning, custom event schema, e-commerce tracking, cross-domain setups, user-ID stitching and QA testing. So you start collecting accurate, future-proof data on day one and never miss a conversion signal.
Beyond simple clicks and pageviews, we architect robust Google Tag Manager solutions: custom data layers tailored to your business logic; server-side tagging for performance and privacy; dynamic event triggers; user-property enrichment and full documentation to keep your marketing and dev teams in sync.
Leverage BigQuery to its fullest: we’ll design ETL pipelines that pull in GA4 exports, CRM data and ad metrics; build optimised, partitioned tables; write reusable SQL models; and hand you self-serve query templates. The result? Lightning-fast access to granular insights across millions of rows.
Ditch static spreadsheets, our interactive dashboards (Looker Studio, Data Studio, Power BI) automatically refresh your key KPIs, blend data sources (ads, email, on-site events) and layer in drill-down filters. You’ll get one pane of glass for acquisition, behavior and revenue metrics, complete with anomaly alerts and scheduled reports.
We run end-to-end CRO programs: UX audits and session-replay analyses identify friction; we craft bold, data-driven hypotheses; set up rigorous A/B and multivariate tests in Optimizely, VWO or Google Optimize; and apply strict statistical methods. When winners emerge, we implement site-wide rollouts and build a prioritizsed testing roadmap for sustained uplift.

“We brought in the team to help make sense of our analytics and improve our conversion rates. They didn’t just give us reports, they helped us understand what was actually happening on our site and what to do about it. Within weeks we were seeing clearer insights and better results from our campaigns. Highly recommend if you want to make data actually work for you.”
