Projected from the audit record. After fixing, re-run the task or re-measure to confirm.
AI agents successfully accessed johnlewis.com without encountering bot blocks, but achieved only a 30% task success rate. The absence of foundational routing files like `/llms.txt` and `/sitemap.xml` left agents without a clear map of the site's structure. Consequently, agents were forced to rely heavily on external search engines to find information for six out of ten tasks. While tasks like shipping, contact, and signup were fully successful, critical e-commerce intents like checking stock and finding the latest products failed entirely. Providing machine-readable pathways and ensuring key pages are discoverable via direct HTML links will significantly improve agent performance.
What works
- The site does not block AI agents, allowing basic access and returning a 200 HTTP status on the homepage.
- Agents successfully completed shipping, contact, and signup tasks while citing the site's own URLs.
- Policy, compare, locations, and signup intents were navigated natively without relying on external search bridges.
