Supan SEO

About the name: "Supan" (スパン) is a Japanese loanword meaning "span" — the arc or spectrum of connections. It reflects the family of Supan plugins for WordPress site management. Most WordPress sites bleed organic traffic silently — missing meta tags, weak title lengths, no structured data — and no one ever tells you why. Supan SEO gives every post and page a real score (0–100), breaks down every failing check in plain English, and generates FAQ JSON-LD schema to push you into Google featured snippets and AI answer engines like Perplexity and ChatGPT. No guesswork. No third-party dashboards. Just clear, actionable SEO insights — from inside wp-admin. Key Features

• Instant SEO score (0–100) — know which pages need work: title length, meta description, H1 presence, keyword density, and more
• GEO / AEO scoring — optimise for AI answer engines (Perplexity, ChatGPT, Gemini) alongside traditional Google
• Plain-English fix suggestions — every failing check comes with a specific, actionable recommendation
• FAQ schema generator — produce ready-to-inject JSON-LD structured data from any topic in seconds
• AI Citation Check — paste a topic query and see whether Perplexity AI cites the analysed page
• llms.txt builder — generate the AI-crawler discovery file at your site root with one click
• Live post/page dashboard — see scores for your entire site at a glance, updated every time you run an analysis
• Works with Yoast SEO & RankMath — reads existing meta fields automatically, no duplicate setup
• Gutenberg sidebar — analyse the post you're editing without leaving the block editor
