Pillark – Pillar & Cluster Internal Linking

Pillark gives you a clear overview of your pillar pages and the content clusters built around them, plus the internal-linking tools to keep that structure healthy. Pick your Pillar pages, and Pillark automatically maps which posts link to them, scores each cluster’s structure, and flags what’s missing.

Everything runs inside your own WordPress admin. The plugin reads your existing posts and pages, builds an internal link map, and reports on the parts of onsite SEO that are easy to overlook.

Built by Lasse Enggaard (https://lasse-enggaard.dk) at Webro (https://webro.dk). Plugin home: https://pillark.org

Source code: https://github.com/LasseEnggaard/pillark — there’s no build step or compiler involved; the JavaScript and CSS shipped in the plugin are the exact same files in the repository, not a compiled or minified output.

What it does

• Clusters – choose your Pillar pages and see each one’s cluster at a glance: incoming and outgoing links, two-way linking, topic coverage, freshness, and a per-Pillar quality score with concrete suggestions.
• Post overview – a sortable, filterable table of every post with word count, internal links, featured image, images missing alt text and more. Exports to CSV.
• Internal link profile – see which pages link where, the anchor texts used, and how link equity flows across the site.
• Orphan detection – find posts and pages that receive no incoming internal links.
• Link suggestions – get suggestions for relevant internal links between related content.
• Keyword cannibalization – detect posts competing for the same focus keyword.
• Duplicate anchors – find identical anchor texts pointing to different URLs.
• Content CTA button – optionally insert a call-to-action button into post content, with per-post and per-category exclusions.

Works with Yoast SEO

The keyword cannibalization report uses Yoast SEO’s focus keyword data, and the per-Pillar cluster score includes Yoast’s SEO title, meta description and focus keyword as one of its signals when Yoast is active. Neither is required — the internal link analysis, cluster overview and other tools all work without Yoast installed. This is an independent plugin and is not affiliated with, endorsed by, or connected to Yoast.
