AuditySEO

AuditySEO Canonical Manager gives you complete, granular control over the canonical URL of every page on your WordPress site: posts, pages, custom post type entries, taxonomy terms, archive pages, and even the pagination pages WordPress generates automatically.
Missing or incorrect canonical tags are one of the most common technical SEO problems on WordPress sites. They let search engines index duplicate versions of the same content, split your ranking signals across multiple URLs, and waste crawl budget on pages that should never compete for the same keywords. AuditySEO Canonical Manager fixes this at the source, so every URL on your site points search engines to the page you actually want ranked.
<h4>Free features</h4>
<ul>
<li>Lists pages, posts, custom post types, terms and archives in a dedicated AuditySEO Canonicals admin screen.</li>
<li>Shows the default canonical URL that WordPress (or your SEO plugin) would output for each item.</li>
<li>Detects content pagination created with the <code></code> tag.</li>
<li>Detects pagination of the posts page (<code>page_for_posts</code>) based on the number of published posts and <code>posts_per_page</code>.</li>
<li>Detects pagination of taxonomy term and archive listings.</li>
<li>Lets you set a custom canonical URL per item and per pagination page.</li>
<li>Applies your overrides through the canonical filters of WordPress core, Rank Math and Yoast SEO.</li>
<li>Rewrites the <code><link rel="canonical"></code> tag in the final HTML output as a fallback for themes, caches and plugins that print a canonical outside of those filters.</li>
<li>Imports and exports canonical overrides via CSV, with a dry-run preview before bulk changes are applied.</li>
<li>Validates canonical URLs when you save them (HTTP status, redirects, noindex, external domain) without blocking the save, and flags the affected item with the reason until it is fixed.</li>
<li>Filters the editor by status, override state and pagination.</li>
</ul>
<h4>Pro features</h4>
Upgrade to AuditySEO Canonical Manager Pro to unlock:
<ul>
<li>History & restore – every change to a canonical override is recorded with the user and date, and can be rolled back with one click.</li>
<li>Automatic canonical fixes, applied site-wide:
<ul>
<li>Replace pagination canonicals that point to page 1 with each page’s own self-referencing URL.</li>
<li>Strip tracking parameters (utm_*, gclid, fbclid, msclkid, and more).</li>
<li>Strip display-variant parameters (print, amp, output, format, replytocom, and more).</li>
<li>Force the canonical to always match the requested URL exactly, including its query string.</li>
</ul>
</li>
</ul>
The free version is fully functional on its own and does not require the Pro upgrade to manage canonical overrides, detect pagination, validate URLs or import/export CSV files.

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.
<h4>Key Features</h4>
<ul>
<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>
<li>Near-duplicate content finder — configurable similarity threshold to catch keyword cannibalisation before it costs you rankings</li>
<li>One-click graph build — analyses up to 200 published posts and pages automatically</li>
<li>Copy-to-paste anchor HTML — insert suggested links without writing a single line of code</li>
</ul>
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.
<h4>External Services</h4>
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.
