Duplicate Content Cure is an extremely simple plugin that makes WordPress more Search Engine 
friendly (And therefore improving SEO). It does this by preventing search engine spiders/bots 
from accessing pages like Archives, Tags, and Categories, which tend to contain duplicated content 
from elsewhere on your site. This is achieved by adding nofollow, noindex to 
these problem pages.
Duplicate Content Cure doesn’t have a lot of features that other SEO plugins have, but 
it also is lightning fast by comparison.

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.

<li>Internal link graph — see exactly which pages link to which, with orphan pages flagged at a glance</li>
<li>Orphan page detection — instantly find pages with zero inbound internal links dragging down your authority</li>
<li>AI-powered link suggestions — semantic engine matches your posts by topic and recommends the highest-impact linking opportunities</li>
<li>Topic cluster mapping — group your content by semantic category to build true topical authority</li>

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.
