Smart Internal Links review
A free, open-source WordPress plugin for reviewing internal-link suggestions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Smart Internal Links is a free, open-source WordPress plugin for finding and approving internal-link opportunities. It analyzes published content for phrases matching other post titles, then presents suggested source and target posts for review. The plugin suits WordPress users who want a controlled way to identify linking opportunities without relying on automatic link insertion or a separate content workflow.
Its strongest capability is bulk analysis. Users can scan the entire website or selected groups of posts, compare phrase matches against published post titles, and review suggestions before approving them. Configurable phrase sizes, maximum links per post, and post types provide control over how broadly the plugin identifies opportunities. This makes it useful for larger post libraries as well as more focused review groups, while keeping approval in the editor's workflow.
Platform fit is straightforward: Smart Internal Links integrates with the Classic Editor through a meta box and with Gutenberg through a sidebar. Its non-destructive link injection approach stores links separately from post content before injecting them at display time, which supports a review-based process without directly modifying the underlying post text. The main tradeoff is its narrow scope: it suggests and injects approved links but does not automatically link content or detect orphan pages. Choose it for free, configurable suggestions inside self-hosted WordPress; consider another tool if automatic linking or orphan-page discovery is essential.
