CodeZine

CodeZine is a business whose own site puts it this way: "「CodeZine（コードジン）」は、株式会社翔泳社が運営する、開発者のための情報メディアです。テクノロジー入門からAI活用、キャリアまで、ソフトウェア開発にかかわるすべての人の学びと成長を支える最新情報と実践知をお届けします。." To AI engines like ChatGPT and Perplexity it is partially visible, scoring 5.7 out of 10, readable in places, missing in others.

Almost none of the machinery AI engines read is present, including structured data describing the business, an llms.txt file, a sitemap.

AI crawlers have visited the site once in our tracking, so the engines are already looking.
