Research principles

Our public research aims to:

• use primary and official sources whenever possible;
• publish data and reproducibility materials when they can be shared safely;
• document methodology, environment, assumptions, and limitations;
• distinguish measured findings from documentation, interpretation, and inference;
• avoid production credentials, personal data, customer identifiers, and live client assets;
• preserve frozen releases when a publication cites a specific dataset;
• explain complex technical topics in a way that remains useful to readers with different levels of experience.

Topics we cover

• Google Analytics 4
• Google Tag Manager
• Server-side tagging
• Consent Mode and privacy-aware measurement
• Google Ads and conversion tracking
• Merchant Center and ecommerce diagnostics
• Measurement Protocol and offline conversions
• CRM and webhook integrations
• Attribution and data quality
• Technical SEO
• Core Web Vitals and web performance
• Advertising platform changes and implementation risks
