How we counted
For NovaAct, our 19 October 2026 collection used Tranco’s top 10,000 sites. Requests could run for 8 seconds, with a 262,144-byte file limit. Missing, unreachable and oversized files do not contribute to these shares. Collection and repeat readings used scripts/robots_2026_08_06.py (robots.py at app commit 07104ff).
