About Propeller

from our crawl and measurement

Perfect for entrepreneurs, remote workers, freelancers and creatives to...." Its AI visibility score is 5.1 out of 10: the engines can find it, but they do not have much to hold on to.

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

Our monitoring has logged 2 AI crawler visits here: the engines come, the question is what they find.
