Signal breakdown

The score above combines two different things: whether an agent can understand this site at all, and whether the site has adopted the emerging optional agent conventions. They're grouped separately here because a site can be excellent at one and have none of the other.

Comprehension

Whether an agent can read and understand the page at all.

12/58(21%)

Agent convention adoption

Whether the site has adopted the emerging optional agent conventions.

24/42(57%)
