Free (core features), $69.99/year (Pro - 1 site)

WPLink.AI
Our Pick$60 one-time (Solo), $199 one-time (Agency) - lifetime license, unlimited WordPress sites. Launch pricing. Ollama support for free AI processing.

With Ollama configured, WPLink provides full semantic analysis, vector-based link discovery, and AI-generated anchor text suggestions without paying for any API keys. The one-time license fee is the only cost, and it delivers genuinely AI-powered linking rather than keyword matching. Check WPLink pricing for current launch offers.

Link Whisper (Free Version)
Free (reporting only), $77/year (1 site - full features)
Link Whisper offers a limited free version on WordPress.org that provides basic internal link reporting. The free version shows your internal link counts and helps you identify orphan content. However, the actual link suggestion engine and bulk link management features are reserved for the premium version. It is useful as a diagnostic tool but does not offer free link suggestions.

Linkilo (Free Tier)
Free (limited suggestions), $59/year (1 site - full features)
Linkilo provides a free tier that includes basic link analysis and a limited number of link suggestions per month. The free version lets you explore the plugin's interface and get a taste of its AI-powered suggestions before committing to a paid plan. While the suggestion limits make it impractical as a long-term free solution for active sites, it is a useful way to evaluate AI-powered linking at no cost.

- + Good way to evaluate the tool before committing to a paid plan
- + Modern interface that is pleasant to use even in the free version

What to Look for in a Free Internal Linking Plugin
Active Suggestions vs. Passive Monitoring
The most important distinction among free tools is whether they actively suggest links or merely report on your current linking status. A tool that only counts links tells you there is a problem but does not help solve it. A tool that suggests specific links or auto-inserts them provides direct value. Learning how to audit internal links can help you evaluate which approach your site needs. Internal Link Juicer's free version, for example, actively inserts links, while Yoast's free version only counts them.
Upgrade Pressure and Feature Gating
Some plugins offer genuinely useful free tiers, while others gate essential features behind paywalls and use the free version primarily as a marketing funnel. Look for tools where the free version provides real, daily-use functionality rather than just a teaser. Check whether suggestion limits, post type restrictions, or feature locks will frustrate you after the initial setup.
Setup and Maintenance Effort
Free tools often require more manual configuration than their paid counterparts. Keyword-based tools need you to define target keywords for every post, which is manageable for small sites but becomes tedious at scale. Consider how much time you are willing to invest in setup and ongoing maintenance versus what the tool does automatically.
Compatibility with Your SEO Stack
If you already use an SEO plugin like Rank Math or Yoast, their built-in linking features might be sufficient and avoid plugin conflicts. Adding a dedicated linking plugin on top of your SEO suite can sometimes cause conflicts or redundant functionality. Check compatibility before installing multiple SEO-related plugins.
Long-Term Total Cost
Free today does not always mean free forever. Consider what happens when your site grows beyond the free tier's limits. If you will likely need premium features within a year, compare the annual cost of upgrading against tools with one-time pricing. A free tool that costs $70/year after six months may not be cheaper long-term than a $60 one-time purchase (launch pricing).
Our Recommendation
For a truly free solution, Internal Link Juicer offers the best balance of functionality and zero cost, with automated keyword-based linking that works well for small to medium sites. If you already use Rank Math or Yoast, their free linking features may be all you need to monitor and improve your link structure. For those willing to make a one-time investment to escape the limitations of free tools, WPLink.AI with Ollama delivers AI-powered semantic linking with no recurring costs.
