Borderline visible. AI bots can crawl NASA Science, but the structured-data signals are thin - you are at real risk of being skipped when buyers ask ChatGPT, Claude, or Perplexity for a recommendation.

About NASA Science

from our crawl and measurement

NASA Science describes itself simply: "Mars is the fourth planet from the Sun, and the seventh largest. It’s the only planet we know of inhabited entirely by robots." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.0 out of 10.

Under the hood there is structured data on the page (Organization, WebSite, ImageObject) and a readable heading structure and substantial page content, but the score is capped by what is missing: an llms.txt file, a sitemap.

What this score means

Your AEO score measures whether AI search engines - ChatGPT, Claude, Perplexity, Gemini - can actually read your site and cite it in answers. Roughly two-thirds of sites are invisible to them. At 4/10, NASA Science is crawlable but under-signaled - fixable, and the signals above are where to start.

Frequently Asked Questions

Why Do We Go?

Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to explore the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.
