Not tested

We tested the broad category“ai writing assistant”— because it is the most contested place to appear and the hardest first test to pass: the generic questions a buyer asks before they’ve named a specific tool. So the 80% above is a precise, limited finding about that broad category only. It does notprove the site is invisible in its own narrower niche — only the broad category was measured this run. A follow-up run should test prompts specific to the site’s real category.

Tested = measured on real AI answers this run. Not tested = no answer was generated, so no score is claimed.
