Internal Linking & Topic Cluster Planner

Internal links tell search engines which pages matter and how they relate. Paste your pages and topics and get a pillar-and-cluster link plan, with orphans and missing pillars flagged, ready to implement.

Quick answer: a topic cluster is a pillar page linked to and from every supporting page on that topic, which concentrates authority and helps you rank for the whole subject. This planner groups your pages by topic, identifies each pillar, generates the internal links to add, and flags orphan pages and clusters with no pillar.

Plan your internal links

Runs in your browser. Paste one page per line as url | topic | role. Role is pillar or cluster (leave blank for cluster).

Who uses this and why

You publish a lot but rank flat

Good posts that never quite break through often lack internal links pointing authority at them. Clustering shows exactly which links to add.

You want to build topical authority

Ranking for a whole subject, not one keyword, comes from pillar-and-cluster structure. This plans it from your existing pages.

You suspect orphan pages

Pages with no internal links pointing to them are nearly invisible to search engines. The planner flags orphans so nothing is stranded.

Handing work to a writer or VA

Export a concrete from-to link list with anchor suggestions that anyone can implement without guesswork.

Internal links do three jobs at once: they help search engines discover pages, they pass ranking authority between pages you control, and they signal how your content relates. Unlike backlinks, they are entirely in your hands, which makes them one of the highest-leverage, lowest-cost things you can improve. Yet most WordPress sites link almost at random, a few in-body links here, a related-posts widget there, leaving important pages under-linked and orphan pages invisible. A deliberate structure changes that.

The pillar-and-cluster model

The durable structure is the topic cluster: one broad pillar page covering a subject, surrounded by focused supporting pages that each go deep on a sub-topic. Every supporting page links up to the pillar, and the pillar links down to each supporting page. This concentrates authority on the pillar, tells search engines you cover the topic comprehensively, and helps the whole group rank, exactly the kind of depth that both Google and AI answer engines reward. This planner takes your pages and topics, assembles the clusters, generates the up-and-down links, adds light sibling links, and flags the two failure modes that break the model: clusters with no pillar (authority has nowhere to concentrate) and orphan pages (stranded with no links in).

The plan lists the links; implementing them well means writing natural anchor text, placing links in relevant context rather than stuffing them, and deciding which pages truly deserve to be pillars as your content grows. Done thoughtfully it compounds; done mechanically it reads as spam and helps little.

Frequently asked questions

What is a topic cluster?
A topic cluster is a broad pillar page on a subject linked to and from a set of focused supporting pages about sub-topics. The structure concentrates authority and signals topical depth, helping the whole group rank. This planner builds the cluster and its links from your pages.
Is this internal linking tool free?
Yes, free with no login, and it runs in your browser. Paste your pages and topics and it returns a pillar-and-cluster link plan with orphan and missing-pillar warnings, downloadable as CSV.
What is an orphan page?
An orphan page has no internal links pointing to it, so search engines struggle to find and value it. This tool flags pages with no topic assigned as likely orphans so you can link them from a relevant page or fold them into a cluster.
How many internal links should a page have?
There is no magic number; link where it genuinely helps the reader and reflects real topical relationships. The pillar-and-cluster pattern gives a sensible baseline: each supporting page links to its pillar and the pillar links back to each supporting page, plus contextual links where relevant.
What anchor text should internal links use?
Use descriptive, natural anchor text that reflects the destination's topic, not generic phrases like click here or read more. This tool suggests the cluster topic as a starting anchor; adapt it to read naturally in context.
