What changed
What changed between ARC's two most recent open-data snapshots: stores that started or stopped serving a valid UCP profile, blocking AI crawlers, or returning a checkout link, plus adoption trends by platform across every dated snapshot.
Snapshot 2026-10-30 (30 Oct 2026) to 2026-11-06 (6 Nov 2026)
30 Oct 2026 → 6 Nov 2026
Compared from store_answers.csv in 2026-10-30 (10,662 stores) and 2026-11-06 (10,750 stores). A store counts as changed only when both readings finished; unknown, turned-away and not-tested readings never count as a change. 19 opted-out stores are left out. No store in the earlier snapshot is missing from the later one.
Newly serve a valid UCP profile (1)
ucp_profile_valid was a finished reading other than yes in the earlier snapshot and yes in the later one.
- ae.comno profile found at the host on 30 Oct 2026 → yes on 6 Nov 2026 · Not detected
No longer serve a valid UCP profile (0)
ucp_profile_valid was yes in the earlier snapshot and a finished reading other than yes (no or not_found_at_host) in the later one.
None between these two snapshots.
Started blocking AI crawlers in robots.txt (1)
blocks_ai_crawlers went from no to yes. A rule in a file, not an observed block.
- bim.com.trno on 30 Oct 2026 → yes on 6 Nov 2026 · Not detected
Stopped blocking AI crawlers in robots.txt (1)
blocks_ai_crawlers went from yes to no.
- eldi.beyes on 30 Oct 2026 → no on 6 Nov 2026 · Adobe Commerce / Magento
Checkout link: no → yes (0)
can_agents_get_checkout_link went from no to yes. ARC stops before paying, so yes means an agent reached checkout, not that an order was placed.
None between these two snapshots.
Checkout link: yes → no (0)
can_agents_get_checkout_link went from yes to no.
None between these two snapshots.

Adoption trends by platform
Every dated snapshot that publishes store_answers.csv (2026-10-09.r3, 2026-10-12.r3, 2026-10-30, 2026-11-06), 9 Oct 2026 to 6 Nov 2026. Each point is one snapshot. The store list grew between snapshots, so a change in a share can come from which stores were added, not only from stores changing. Shopify is platform Shopify; Not Shopify is every other value, including Not detected and empty. Opted-out stores and checks that did not finish are left out of every denominator.
Denominator: completed checks (can_agents_get_checkout_link yes or no). Snapshots 9 Oct 2026, 12 Oct 2026, 30 Oct 2026, 6 Nov 2026.
