What Link&Cluster is
Link&Cluster is a WordPress plugin for finding internal-link opportunities and organizing content into topical clusters. Its overview highlights paragraphs where links to existing site content may fit, and users can review link counts across posts, then sort or filter them. Clusters can be built from categories or custom taxonomies, with the plugin prioritizing links within those groups. It can insert a related-posts box into other posts, and its design and wording are customizable. The free Starter plan includes incoming internal link counts, outgoing external link counts, and counts by category. Pro costs $44, paid once and adds link opportunities, taxonomy counts, cluster assistance, one-click internal links and related-post boxes, plus lifetime updates. The maker says links embedded in posts in Editor Mode remain after uninstalling the plugin. Purchases have a 14-day money-back guarantee. Installation requires uploading the plugin to WordPress’s wp-content/plugins directory and activating it. The WordPress.org listing says it has not been tested with the latest three major WordPress releases.
