All of them together: 92 (A)
Projected from the audit record. After fixing, re-run the task or re-measure to confirm.
Agents successfully connected to the site without encountering bot blocks and located standard files like sitemap.xml and robots.txt. However, the overall task success rate is only 20%, with 8 out of 10 intents failing to yield complete answers. The site forces agents to rely heavily on external search engines to find pages for contact, locations, support, and latest news, rather than providing clear internal pathways. Additionally, the absence of an /llms.txt file causes agents to guess URLs, leading to 404 errors and complete failure when searching for documentation.
What works
- The site does not block AI agents and returns a healthy HTTP 200 status on the homepage.
- Standard discovery files (sitemap.xml, robots.txt) are present and accessible.
- Agents successfully completed the 'signup' and 'careers' tasks while citing the site's own URLs.
- When agents do find content, they cite the site's own URLs 90% of the time.
What to fix
For each item: its current state, why it matters, how to fix it and how to check. The same content comes as files you can hand straight to whoever does the work.
