Audit third-party servicessave ~0.0021 g/visit (17 kB)Medium impact · moderate effort
3 third-party domains account for 35 kB (65% of the page).
Remove services that no longer earn their place; load the rest on interaction (facades for embeds, delayed consent-gated tags). Each third party is also a privacy and performance dependency.

Fix caching for returning visitorssave ~<0.001 g/visit (28 kB)Medium impact · quick fix
On a repeat visit 111 kB of static assets were re-downloaded instead of coming from cache.
Serve static assets with Cache-Control: public, max-age=31536000, immutable and versioned filenames so returning visitors download almost nothing.
