About
The AI-powered internal linking plugin for WordPress. Build internal links faster, find linking opportunities, and improve SEO automatically.
Security History
What It Does
Link Whisper Free analyses your existing posts and pages to surface internal linking opportunities based on content relevance and keyword matching. It adds an inline link suggestions panel inside the WordPress editor so you can insert internal links without leaving the post, and it helps flag orphan content that has few or no internal links pointing to it. The free tier covers the core suggestion workflow while a paid version unlocks automatic linking and deeper reporting.
Who It's For
This plugin is best for content-heavy WordPress sites that already publish frequently and want to improve crawl paths and on-page SEO without manually auditing every post. It suits bloggers, news publishers, knowledge bases, affiliate sites, and agencies that manage large archives and need to retrofit internal links to older content quickly. Sites with under 30 or so posts will see limited value since there are simply not enough existing pages to link between.
Who Should Skip It
If your site has fewer than 20 published posts, a simple manual linking approach will be faster and give you better control over anchor text. Anyone wanting fully automatic internal linking, advanced reporting, or AI-driven suggestions should look at the paid Link Whisper tier or a competing tool instead, since the free version caps the most useful automation features.
The Bottom Line
Link Whisper Free delivers a focused internal linking workflow that does one job well, and its strong maintenance and compatibility scores make it a safe pick for older or larger sites. The free tier strips out the headline AI and automatic linking features, so heavy users will likely outgrow it and need to upgrade or switch. Overall Quality Score of 79.85 out of 100 places it as a useful niche tool rather than a must-have.
