How to verify Quickload is actually working on your site
Five tests, ordered cheapest to most thorough, to confirm the engine is rewriting tags and improving CWV.
Five tests, ordered cheapest to most thorough.
1. View page source
Right-click your homepage, View Page Source, search for text/quickload. Any cross-origin script tag should now have this MIME type — the browser parks it instead of executing it.
2. Watch the runtime in real time
Open your site with ?quickload_debug=1. The console will show purple [Quickload] logs: Initialized on load, then Firing group "interaction" the moment you scroll or tap, followed by Activated for each script.
3. Watch the network tab
Reload the debug URL with the Network tab open. Before scroll: no third-party scripts requested. After scroll: GTM, GA, Pixel, Hotjar all appear. That's the proof.
4. PageSpeed Insights
Run PSI on your homepage with the plugin disabled, then enabled. TBT and LCP should drop measurably. INP improves on real-user data over a few days, not synthetically.
5. Discovered Scripts page populates
After a few visits, the Discovered Scripts admin page lists every cross-origin URL the runtime activated. This is your live tag inventory.
