AI・LLM時代対応のWordPress SEOツール
当研究室で開発したWordPress向けのSEOテーマ・プラグインを無料公開しています。検索エンジン最適化の基本機能から、AI・LLM時代に対応した最新技術まで、実務で培ったノウハウを実装したツール群です。
SEO最適化ベーステーマをはじめ、構造化データの自動生成、XMLサイトマップ管理、メタ情報の最適化、パンくずリスト生成など、SEO対策に必要な機能をプラグインとして個別に提供しています。コーディング不要で、WordPress管理画面から簡単に導入・設定が可能です。
なお、「Backbone Theme for SEO + LLMO」をご使用になる場合は、関連プラグイン群をセットで導入することを強く推奨します。テーマ単体では完全なパフォーマンスを発揮できないため、各プラグインを組み合わせることで、最大限のSEO効果を実現できます。
ツールはすべて柏崎剛のGitHubでオープンソースとして公開しており、継続的にアップデートしています。目的に合わせて、必要なツールをお選びください。
