How we counted

For Brightbot, on 19 October 2026, we requested robots.txt from Tranco’s top 10,000 sites. Each file had 8 seconds to arrive, up to 262,144 bytes. Only available files we could read enter the percentages. Later readings are included in results from scripts/robots_2026_08_06.py (robots.py at app commit 07104ff). See the full survey method.
