[レベル: 中級] rel="prev" および rel="next" のリンク要素のサポートを終了したことを Google は Twitter で告知しました。 Spring cleaning! As we evaluated our indexing signals, we decided to retire rel=prev/next. Studies show that users love single-page content, aim for that when possible, but multi-part is also fine for Google Search. Know and do what's best for *your* users! #springiscoming pic.twitter.com/hCODPoKgKp — Google Webmaste
