Two-way links
Which supporting pages link up to the pillar and get a link back. These are the ones holding the cluster together.
Your cluster is only as strong as the links you forgot
Pillark reads the internal links between your pillar page and everything around it, then shows you what is missing. That includes the pages which mention each other but never link.

How it works
Every cluster on one screen
Pick the page a cluster is built around. Pillark maps every internal link on the site and shows each supporting page as a card. Green means the link runs both ways, blue means it runs one way, and grey means a page mentions the pillar without linking to it.
- No settings to configure
- Nothing is written to your content
- Analysed once and cached
Internal link profile
Every page, and where its links go
One table covers every published page and post. It shows how many pages link in, how many it links out to, external links, dead internal links and when the page was last touched.
Pages with no incoming links at all are marked in red. Those are the ones search engines are least likely to find.
- Links in and out, split by pages and posts
- The anchor text used most often to link in
- Filters for orphans, dead links and old pages
Linking opportunities
The links you already wrote, without the link
Pillark compares every page against every other one. When a page names another by title but does not link to it, that pair is listed with the page to open.
These are the cheapest internal links you can add. The sentence is already there and the context is right, so all that is missing is the link itself.
- Only reported when one page genuinely mentions the other
- Opens the editor at the page that needs the link
What it finds
Six things Pillark tells you about a cluster
Everything is computed from your own content. No API keys, no external service, no data leaving your site.
One-way links
Pages that link up without a link back, or the reverse. This is often deliberate, so Pillark shows it as a note rather than an error.
Unlinked mentions
Pages that already name another page without linking to it. These are the easiest internal links to add.
Weak anchor text
Links that say "read more" or "click here" instead of describing the page they point to.
Dead internal links
Links pointing at pages that no longer exist. Each one is checked against posts, pages, archives and taxonomies, so the count can be trusted.
Pages you add yourself
Attach an existing page to a cluster by hand while restructuring, before the links between them exist.
Scope
It does not replace your SEO plugin
Titles, meta descriptions, sitemaps and schema output are solved problems, and Yoast SEO and Rank Math give them away for free. Pillark deliberately stays out of that work and does the part nobody else covers.

Questions
Before you install
No. Pillark reads their data where it is useful, such as the focus keyword used for the cannibalization report, and never writes to it. All three can run together.
Everything is computed in one pass and cached, so the cost is the same whether you open one cluster or ten. Sites with a few thousand posts are fine.
Never on its own. Pillark tells you what to add and opens the editor at the right page. You write the link.
Any page that links to your pillar, any page your pillar links to, and any page you attach by hand while restructuring. The front page is never counted, since it links to and is linked from everything.
Yes, on WordPress.org, with no paid tier and no upsell inside the plugin.
