What it is

Link&Cluster is a self-hosted WordPress plugin for finding internal-link opportunities and organizing topical clusters. It highlights paragraphs where links to existing content may fit, and reports internal-link counts across posts with sorting and filtering. Clusters can use categories or custom taxonomies, with links inside those groups prioritized. The plugin can insert a related-posts box into other posts, and its design and wording can be customized. Starter is free at free and includes incoming internal-link counts, outgoing external-link counts and counts by category. Pro costs $44, paid once, billed as Buy once, with lifetime updates; it adds link opportunities, taxonomy counts, cluster assistance, one-click internal links and related-post boxes. Links embedded in Editor Mode are said to remain after uninstalling. Purchases include a 14-day money-back guarantee. Installation involves uploading the plugin to WordPress’s wp-content/plugins directory and activating it. Paid support is listed through the WordPress.org forum. The WordPress.org listing says the plugin has not been tested with the latest three major WordPress releases.
