How many sites block it?

The 253 files blocking the whole site account for 4.1% of 6,171 readable robots.txt files. We found its name in 30 User-agent lists, a 0.5% share. Without a whole-site Disallow: / block, 5,918 files remain.

Among 552 readable files from the top 1,000 sites, we found 4 files naming it, a 0.7% share, with 44 files blocking the whole site. Blocking is more common among the leading sites, at 8.0%. Outside this group, 5,619 files contribute 209 blocks, or 3.7%.

A general User-agent: * ban contributes to this total whenever it applies to this crawler. Of 253 blocks, 227 come only from that general rule, without naming this crawler. Looking just at named files gives 26 blocks and 4 without a whole-site block. For 6,141 readable files, we found no mention by name. We ignore capitalization and repeated names.

Has that changed since August?

Between August and October, 15 sites that had blocked it stopped and 21 started, so 6 more of the same 5,889 sites block it. A further 201 blocked it in both months, and 5,652 did so in neither. Keeping the sites the same lets us count changes in their rules.

August’s full sample had 231 blocks among 6,236 readable files. October’s was 253 among 6,171. Those monthly totals also reflect which files we could read on each visit.
