Gorilla Drill

Gorilla Drill describes itself simply: "小学 1 年生から中学 3 年生までを対象に、毎日の学習ドリルを PDF で無料ダウンロードできる家庭学習サポートサービスです。." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 3.7 out of 10.

On the page itself the strengths are clear: a clear heading structure and crawler access and the files AI engines look for. It is passable on some structured data, a partly stated business identity and partial sitemap and link coverage. What holds it back is credibility markers like credentials or reviews.

Off the page, almost no other sites link to it, the domain does not yet read as established, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on, nobody is discussing it where AI engines look and it does not come up on Reddit. Those are earned elsewhere on the web, not fixed on the site itself.

There is not much on the page to read either, about 132 words. The site links to no social profiles, so there is nothing tying the brand to a wider presence.
