Projected from the audit record. After fixing, re-run the task or re-measure to confirm.
Agents can access the homepage and successfully complete tasks related to careers and signups using the site's own URLs. However, for the majority of intents, agents fail to find the necessary information on-site and are forced to rely on external search engines. This results in a low 20% task success rate and a 40% own-source citation rate, meaning users are often getting information about the BBC from third-party sources. Furthermore, agents encountered errors when trying to access support and documentation pages, indicating missing or broken standard paths. Implementing an `llms.txt` file and improving internal linking for key intents would significantly enhance agent navigation and content discovery.
What works
- The homepage is fully accessible to bots and provides a healthy number of anchor links (202).
- Standard discovery files like sitemap.xml and robots.txt are present and return HTTP 200.
- Agents successfully completed the 'careers' and 'signup' tasks while citing the site's own URLs.
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.
