In their own words
InterLinks
InterLinks is a Shopify app that automatically turns selected keywords in store content into links to products, collections, or other target URLs. It can place links in product and collection descriptions, blog posts, and pages when those pages load, without changing the underlying content. InterLinks404 extracts keywords from broken URLs and redirects visitors to matching products, collections, pages, or articles; the feature supports 16 languages. The free Demo plan includes one free link, content linking, and InterLinks404 redirects. Professional costs $19 a month or $180/year and includes 5,000 active keywords, unlimited linking automations, an AI SEO Blogger, and a 7-day trial. Professional also offers AI link recommendations based on a store-catalog scan, CSV import and export for bulk keyword management, analytics, and real-time placement reports. The AI blog post generator is powered by GPT-4.1; the plan comparison also names GPT-4o Mini. InterLinks says it works with Shopify themes and major Shopify translation apps. Some page builders or handcrafted themes may need backend installation adjustments. The app lists Shopify as its platform.
Link&Cluster
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.
