原文外掛簡介
Supan SEO is an AI-powered WordPress SEO plugin that scores every post and page (0–100), explains every failing check in plain English, and generates FAQ schema (JSON-LD) to win Google rich snippets and citations in AI answer engines like Perplexity, ChatGPT, and Gemini.
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 fixes that. No guesswork. No third-party dashboards. Just clear, actionable SEO and GEO/AEO 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
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.
Source Code
The full React/TypeScript source for the compiled JavaScript assets is included directly in this plugin under the src/ directory. Build tooling configuration is in vite.config.ts and vite.gutenberg.config.ts.
To regenerate the compiled assets from source:
Install Node.js and pnpm
Run pnpm install in the plugin root
Run pnpm build to produce build/supaseo.js and build/supaseo-gutenberg.js
External services
This plugin connects to the Supan API, a third-party service hosted on Google Cloud Run, to perform on-demand SEO analysis, FAQ generation, llms.txt file building, AI citation scoring, and internal link suggestions. The Supan API is operated by Ganda Tech Services Pty Ltd, the same author as this plugin.
The plugin will not function without this connection because the analysis, AI generation, and scoring logic runs server-side on the Supan API. No analysis happens locally inside WordPress.

What is sent, and when:
When you click Analyse on a post or page (from the plugin dashboard, the Gutenberg sidebar, or the bulk-scan flow): the plugin sends the page’s rendered HTML content, the canonical URL, the page title, the meta description, and your API key. This is needed so the API can score the page and return SEO issues + recommendations.
When you click Generate FAQ: the plugin sends the page title or topic string you entered, plus your API key. Returned JSON-LD is injected into the page.
When you click Build llms.txt: the plugin sends a list of post/page URLs and titles from your site, plus your API key. The returned llms.txt is written to your site root.
When you click Run AI Citation Check: the plugin sends the canonical URL and topic keywords, plus your API key. The API forwards the query to Perplexity Sonar and returns a confidence score.
When you click Suggest Internal Links: the plugin sends the post content and an excerpt of other posts on your site, plus your API key. Suggested anchors come back as a list.
No request is sent automatically. Every API call is triggered by an explicit user action in wp-admin. No request is made from the public-facing front-end of your site, and no visitor data is transmitted.
Data that is NOT sent: WordPress user accounts, comments, post authorship, email addresses, IP addresses, or any post/page that you have not explicitly chosen to analyse.
