Best for: Existing AIOSEO Pro or Elite users
All in One SEO's Link Assistant lives inside the AIOSEO plugin and offers one-click internal link suggestions, orphan-post detection, and domain link reports. It is only included in the Pro and Elite tiers, so it makes most sense if you already use AIOSEO. First-year prices are discounted 50% and renew at list price.

Best for: Rule-based automatic linking on WordPress, with a free starting point
Internal Link Juicer automates linking through a keyword dictionary: define keywords per post and the plugin places links wherever those terms appear, with gap and frequency rules. The free version covers posts and pages; Pro extends to taxonomies and custom fields and adds WP-CLI support and Yoast/Rank Math keyword import.

Best for: WordPress sites that want link analytics alongside auto-linking
Link Manager Pro (formerly Interlinks Manager, by DAEXT) combines keyword-based automatic linking with an analytics dashboard showing internal and inbound links per post, click tracking, and link-equity visualization. A free lite version is on WordPress.org; Pro is an annual subscription by site count.
from $59/yrWordPressFully automatedFree version
Best for: WordPress publishers who want suggestions inside the editor
Link Whisper is the most widely used WordPress internal linking plugin (50,000+ sites). It surfaces AI suggestions inside the editor as you write, adds links with one click, supports auto-linking rules, and reports on orphan posts and broken links, with Google Search Console integration. Pricing is a flat annual fee by site count.

Best for: WordPress owners wanting linking plus site-health tooling in one plugin
Linkilo is a WordPress plugin that bundles internal link suggestions with topic-cluster visualizations, crawl-log analysis (including AI bots such as GPTBot and ClaudeBot), broken-link fixes, redirects, and click analytics. Every tier gets every feature; AI features use your own OpenAI key. It also exposes an MCP interface for Claude and ChatGPT.
from $59/yrWordPressSuggestionsNo free tier
Best for: Rank Math users and budget-conscious WordPress sites
Rank Math Pro's AI Link Genius adds AI-powered link suggestions, orphan-page recovery, and bulk linking to the Rank Math SEO plugin — and unlike AIOSEO it is included in every paid plan. With Pro covering unlimited personal sites, it is the cheapest full-featured internal linking option on WordPress.

Best for: Free related-posts blocks as a supplement to contextual linking
YARPP is a free, long-running plugin that displays related posts based on title, content, and taxonomy similarity. It generates related-content blocks rather than contextual links in body text, and it has not been updated since late 2024 — treat it as a complement to the tools above, not a replacement.

Best for: Sites already on Yoast that want basic suggestions without another plugin
Yoast SEO Premium adds internal linking suggestions to the editor sidebar of the most installed WordPress SEO plugin, alongside redirects, schema, and multi-keyphrase analysis. The suggestions are simpler than dedicated tools — no bulk insertion or link auditing — but for many sites it is already installed.
