About this plugin
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.
