What is link density and how is it calculated?

Link density is the ratio of total links to total words on a page, expressed as a percentage. Formula: (Total Links / Total Words) x 100. It measures how link-heavy your content is relative to text.

What is the ideal link density for SEO?

An optimal link density is between 2-5%. Below 2% means missed internal linking opportunities. Above 5% may signal link stuffing to search engines and dilute link equity.

What is the difference between internal and external link density?

Internal link density measures links pointing to pages on the same domain, while external link density measures links to other domains. Both are calculated as (link count / total words) x 100. A healthy balance favors internal links.

How is the link density score calculated?

The tool scores your page across 6 categories — Link Density, Anchor Text Quality, Link Distribution, Duplicate Links, Empty/Broken Links, and SEO Impact. The overall score averages all category scores.
