Internal linking is one of the most underrated SEO tactics. Google's John Mueller has called it "one of the biggest things you can do on a website to guide Google and visitors to the pages that you think are important."
But doing it manually? That's a time sink. With hundreds of posts, finding linking opportunities becomes nearly impossible.
That's where internal linking tools come in. We tested the top options for WordPress in 2026 to help you pick the right one.
What to Look for in an Internal Linking Tool
Before diving into the tools, here's what separates good ones from great ones:
Link suggestion quality. Does the tool understand context, or does it just match keywords? The difference between AI-powered and keyword-based linking is significant. A tool that links "Apple" to both your fruit recipes and tech reviews isn't helping anyone.
Site performance impact. Plugin-based tools add database queries. Some slow your site noticeably. Desktop apps process locally with zero site impact.
Pricing model. Annual subscriptions add up fast. A $97/year tool costs $485 over five years. One-time payments exist, and they're worth considering.
Automation vs. control. Some tools auto-deploy links. Others suggest and wait for approval. Know which workflow fits you.
Additional features. Orphan page detection, anchor text analysis, broken link checking. These extras can make a real difference.
