Free Internal Link Checker: Audit Anchor Text, Link Distribution & Site Architecture
An internal link checker crawls your website to analyze anchor text patterns, link distribution, and site structure, identifying over-optimization, wasted generic anchors, and keyword stuffing across your internal linking profile. SEOShouts' free tool scans up to 500 URLs and generates a visual word cloud showing which anchor phrases dominate your link structure, a feature no other free tool offers.

“I built this internal link checker after auditing 500+ websites and finding the same pattern: site owners obsess over broken links but completely ignore what their anchor text tells Google. This tool doesn't just find links — it visualizes the words you're using and shows whether they're helping or hurting your rankings.”
What is an internal link checker and why do you need one?
An internal link checker is an SEO tool that crawls your website to map how pages connect to each other through hyperlinks. It analyzes anchor text (the clickable words in each link), tracks link distribution across your site, identifies broken or redirected links, and flags pages that receive too few or too many incoming links.
Most internal link tools stop at finding broken links and counting totals. That misses the point entirely. The real value lies in anchor text analysis — understanding what words you're using to link pages together, because those words directly tell Google what each destination page is about.
Google's John Mueller confirmed this in a Search Central session: “Internal linking is super critical for SEO. It's one of the biggest things that you can do on a website to guide Google and guide visitors to the pages that you think are important.”
According to Semrush's site audit data, 25% of all web pages have zero incoming internal links — effectively invisible to both search engines and users. Meanwhile, Zyppy's study of 23 million internal links found that pages with more anchor text variations receive significantly more clicks from Google, proving that diverse, descriptive anchor text directly impacts traffic.
The SEOShouts Internal Link Checker addresses both problems: it finds underlinked pages AND shows you exactly what anchor text you're using through a visual word cloud that no other free tool provides.

How to run an internal linking audit (step-by-step)
Optimizing your internal linking structure is one of the fastest ways to improve rankings without building a single backlink. A Databox study found that 42% of SEO experts spend equal time on internal links as external links.
Why anchor text is the most underrated ranking factor
Many site owners chase backlinks while completely ignoring the text within those links. Here's why your internal anchor text strategy matters more than most SEOs realize.
The ideal internal anchor text distribution
There's no single perfect formula, but analyzing top-ranking sites reveals a consistent healthy pattern. Aim for this distribution:
| Anchor Type | Example | Target % | Risk Level |
|---|---|---|---|
| Descriptive / Partial Match | "check out our internal link audit guide" | 50–60% | Safest & Most Useful |
| Branded | "according to SEOShouts' analysis" | 20–30% | Builds Brand Entity |
| Exact Match | "internal link checker" | 10–15% | High Power, High Risk |
| Generic | "click here," "read more" | < 5% | Zero SEO Value |
| Naked URL | "seoshouts.com/tools/" | < 5% | Wasted Opportunity |
Zyppy's study of 23 million internal links confirmed that anchor text variety correlates directly with organic traffic — the more unique anchors pointing to a page, the more clicks it receives from Google.
5 common anchor text mistakes (and how to fix them)

How many internal links should a page actually have?
This is one of the most debated questions in SEO, and Zyppy answered it with data.
Their analysis of 23 million internal links found clear patterns:
- 40–44 internal links: The range where pages receive the most clicks from Google
- 45–50 internal links: Peak traffic performance
- 50+ internal links: Traffic declines — Google may discount the value of individual links when pages are link-saturated
- 3–5 contextual links per 1,000 words: The recommended density for in-content links specifically (not including navigation)
The same study found that pages buried 4 or more clicks deep from the homepage receive 9× less traffic than pages within 3 clicks. Internal linking isn't just about anchor text — where you place links in your site hierarchy determines whether pages get found at all.
This is why a holistic internal link audit — anchor text quality AND link placement — delivers the biggest ranking improvements. Our tool handles the anchor text analysis; pair it with a full on-page SEO analysis to evaluate overall page structure and depth.
Optimizing internal links for AI search engines (2026)
AI search is fundamentally changing how internal links function. Google AI Overviews, ChatGPT, Perplexity, Claude, and Gemini don't just follow links — they use them to build semantic maps of your site's knowledge structure.
How AI models interpret your internal links
Traditional search engines follow links to crawl and index pages. AI models go further — they use internal link patterns to understand topical relationships between your content. When your blog post about "anchor text optimization" links to your tool page using the anchor "analyze your anchor text distribution," the AI model learns that these two pieces of content are semantically related.
“A strong internal linking structure gives AI engines clearer semantic signals, making it easier for AI search engines to surface your most authoritative and relevant pages in generative results.”
Natural language anchors beat keywords for AI
AI models process language as vectors — mathematical representations of meaning. Short, robotic keyword anchors provide weak semantic signals. Longer, natural language anchors provide rich context.
| ✗ Old SEO Anchors | ✓ AI-Optimized Anchors |
|---|---|
| "internal link checker" | "use our free internal link checker to audit your anchor text" |
| "best pizza NYC" | "the top-rated pizza places across New York City" |
| "SEO audit" | "run a comprehensive technical SEO audit of your website" |
| "link building" | "proven strategies for building high-quality backlinks" |
The shift is clear: write anchors as if you're explaining the destination to a human, not stuffing keywords for a crawler.
We recommend testing your site's AI visibility weekly. Use our internal link checker alongside proper schema markup and robots.txt configuration for AI crawlers to cover all three key AI visibility signals.
