Supan Content – Internal Links, Orphan Pages & Link Graph

Orphan pages don't rank. Poorly-linked content doesn't rank. But most WordPress sites have hundreds of posts that are one internal link away from a traffic boost — and no way to find them. Supan Content analyses your entire WordPress site to build a visual internal link graph, surface orphan pages instantly, suggest high-value linking opportunities using AI-powered semantic matching, and detect topic clusters — all without leaving wp-admin. Stop publishing new content. Start unlocking the traffic in what you already have. Key Features

• Internal link graph — see exactly which pages link to which, with orphan pages flagged at a glance
• Orphan page detection — instantly find pages with zero inbound internal links dragging down your authority
• AI-powered link suggestions — semantic engine matches your posts by topic and recommends the highest-impact linking opportunities
• Topic cluster mapping — group your content by semantic category to build true topical authority
• Near-duplicate content finder — configurable similarity threshold to catch keyword cannibalisation before it costs you rankings
• One-click graph build — analyses up to 200 published posts and pages automatically
• Copy-to-paste anchor HTML — insert suggested links without writing a single line of code

About the name: "Supan" (スパン) is a Japanese loanword meaning "span" — the arc or spectrum of connections. It reflects what this plugin does: mapping the full span of internal links across your site. External Services This plugin sends post content (title, body text, URLs) to the GTS SEO API (hosted on Google Cloud Run) to perform link analysis, clustering, and duplicate detection.

Data sent: published post titles, content body, and canonical URLs. No user data or PII is transmitted. 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:

1. Install Node.js and pnpm
2. Run pnpm install in the plugin root
3. Run pnpm build to produce build/supaco-content.js and build/supaco-content-gutenberg.js

1.1.2

• The editor sidebar now explains why suggestions are unavailable — "needs a published post or page" — instead of showing a bare "Error 404" on drafts and custom post types.
• Tested against WordPress 7.1.
• The block editor sidebar now resolves its panel components from wp.editor instead of the deprecated wp.editPost. WordPress 6.6 moved them, and reading the old location logged a deprecation notice in the browser console on every post edit screen. WordPress 6.0–6.5 still works via a runtime fallback.
• Editor scripts now declare wp-editor as a dependency so the panel loads correctly under 7.1's always-iframed post editor.
• Packaging: the plugin now ships the full GPL-2.0 licence text rather than a summary of it.
• Plugin, terms and privacy links now point at the current supan.cchk.info product domain, and the author link at g-t-s.com.au. The previous spectra.cchk.info URLs were left over from the Spectra to Supan rename. No functional changes.
