BCompetitive

Costco Travel is accessible to AI agents and performs well for booking and support, but struggles to provide complete answers for pricing, fees, and contact information.

Projected from the audit record. After fixing, re-run the task or re-measure to confirm.

Agents successfully accessed costcotravel.com and navigated its homepage, which contains a healthy number of links. They were able to fully complete tasks related to booking, support, comparisons, and locations. However, agents struggled to find complete information for pricing, fees, policies, and contact details, resulting in partial task failures. The lack of a sitemap and an `llms.txt` file forces agents to guess URLs, leading to errors when searching for contact information and latest updates. Providing structured agent-facing files and ensuring key information is easily discoverable will improve the site's overall AI readiness.

What works

Homepage is fully accessible to agents with 218 raw HTML links for navigation.
High overall reliability (91%) and own-source citation rate (90%).
Agents can successfully complete booking, support, comparison, and location tasks natively or with light bridges.

WebMCP — what the site declares about itself

Not checked

This audit ran with the WebMCP check switched off. That does not mean there are no tools — it means we did not look. Turn on "Check WebMCP" when re-auditing.

Act-stage check (nothing submitted)

Checks whether an agent could fill in the forms and press the buttons, up to the point of pressing. No form was submitted, nothing added to a cart, nothing paid. Report only; not scored.

The act stage was not checked in this audit.
