Clusterlane

Clusterlane turns your categories, tags and other groupings — even pages your custom post types point to — into topic clusters, scores each one, and tells you on every screen what to do next: which articles nothing links to, which mentions can become links in one click, and which article should be the main one.

Free, with no limit on articles:

• Site map — every cluster at a glance, sized by articles and coloured by health.
• Cluster graphs — the pillar, supporting articles and orphans of each cluster, and every link between them.
• Focus next — the clusters where a few links make the biggest difference.
• Improve this cluster and Improve this article — what to fix, most important first, with the fixes one click away.
• Text Match — finds places where an article already names another article without linking to it. Apply links one by one, per article, or the whole list in one run; undo any link, or the whole run.
• Cluster quick view — health and its trend, links, orphans, pillar and the articles to start with, for any cluster in the list.
• Choose each cluster’s pillar — Clusterlane picks the best-linked article, or you choose it yourself.
• SEO title and description preview — from your SEO plugin (Yoast, Rank Math, SEOPress, All in One SEO, The SEO Framework) or your own fields and ACF fields, with length checks and a filter for missing or weak descriptions.
• SEO Titles — every article’s SEO title and meta description on one page, weakest first: filter by cluster, missing or weak descriptions, long titles and duplicates, edit by hand and apply to your own fields, with undo. The first time Clusterlane changes a title or description it keeps the original, so Restore original brings it back.
• Roles and capabilities — decide who can use Clusterlane and who can change its settings.
• Theme links — reads your published pages too, so links your theme adds through lists, cards and related sections count. Pages are read in the background, through the WordPress HTTP API.
• Pages as clusters — for sites built from custom post types that point to each other (areas and their region, hotels and their destination): Clusterlane finds the custom fields by itself, and each page becomes a cluster with the pages pointing to it.
