Find internal linking opportunities and orphaned pages, and add links between related content on your site.
Internal-linking tools range from crawlers that surface opportunities to systems that can insert links automatically. The important differences are how opportunities are discovered, whether suggestions use exact keywords or broader topic/entity understanding, how much editorial control is available, and whether implementation happens through WordPress, JavaScript, or manual edits.

For data-backed link opportunities
#1 of 7 in Internal Linking Tools
Ahrefs Site Audit finds internal-link opportunities by looking at a page's top ranking keywords and then searching other crawled pages for matching mentions. Consider it when rankings and crawl data should inform manual internal-link work; the report identifies the source page, keyword context, and target page, which gives editors a concrete place to add each link.
WordPress suggestions
#2 of 7 in Internal Linking Tools
Link Whisper is built as a WordPress internal-linking plugin. It analyzes content to suggest contextual links while editing and includes reports for internal links and orphaned posts. Because suggestions appear inside the CMS, publishers can review links without exporting crawl data to a separate workflow, which is especially useful for content-heavy WordPress sites.
For automated cross-site linking
#3 of 7 in Internal Linking Tools
Linkbot combines an internal-linking report with an automated bot that can create links through a code snippet. The report highlights orphan pages, link gaps, and prioritized opportunities, while users can exclude pages or keywords and approve or reject suggestions. A separate indexing workflow uses internal links from higher-traffic pages to help expose pages that are missing from Google's index.
Keyword-rule WordPress linking
#4 of 7 in Internal Linking Tools
Internal Link Juicer automates internal links in WordPress from keyword targets configured for individual pages. Rules can vary anchor text, exclude content areas, and use blacklists or whitelists to control where links appear.
Entity-based automation
#6 of 7 in Internal Linking Tools
InLinks builds a knowledge graph of topics mentioned across a site and can create links from those topics to designated cornerstone pages. It supports review before deployment and uses JavaScript for implementation; the entity-oriented method helps teams recognize context and synonyms instead of relying only on exact keyword matches, which changes how suggestions are generated.

Automation can save time on large sites, but relevance still matters to users and search engines. Tools that provide review, exclusion rules, or approval controls are useful when editors need to prevent awkward anchors, redundant links, or links that cross the wrong content silo.
An orphan page is a URL with no discoverable internal links from other pages in the site's crawlable structure. Internal-link tools often flag these pages because users and search crawlers may have difficulty reaching them through normal navigation.
