GA4 wasn't built for Jekyll. Here's what goes wrong.
Jekyll's GA setup requires either the jekyll-analytics gem (which adds a build dependency) or manual Liquid template edits across multiple files
GA's 45KB script is often larger than the entire HTML output of a Jekyll page, making the analytics heavier than the content
GitHub Pages only supports specific Jekyll plugins — custom GA configurations often don't work without a separate build pipeline
Most Jekyll users write technical blogs and personal sites — GA4's enterprise features are complete overkill for this audience
Built for speed, simplicity, and privacy.
One line in _includes/head.html — no gem, no Liquid variables, no _config.yml changes
Works on GitHub Pages without any build pipeline changes or allowed-plugins workarounds
Sub-1KB script makes your Jekyll site even lighter, which matters for readers on slow connections
Perfect for developer blogs — see which posts drive traffic without learning a complex analytics tool

All the insights. None of the bloat.
