Link density describes the number of hyperlinks that are present on a specific web page in relation to the overall volume of content. There is no universally recognized ‘ideal’ link density, but an unusually high number may be flagged as suspicious.
Link density is relevant because Googlebot (and other search engine web crawlers) takes links into account when indexing and ranking websites. When web pages contain an exceptionally high volume of links, it can signal to crawlers that the content is untrustworthy or potentially manipulative.
To mitigate this risk, website owners should focus on producing high-quality content and utilizing internal/external links in an organic and natural way. If a site is victimized by toxic backlinks, its owner can request that Google disavow these links, ensuring they are not considered during the site’s indexation.
