Add internal links from old posts to new cornerstone content

Older, established posts frequently carry accumulated backlink authority and ranking history that a brand-new cornerstone piece, however well-built, simply hasn't had time to develop yet — linking from these established posts to the new cornerstone content is a direct mechanism for passing some of that accumulated authority forward, meaningfully accelerating how quickly the new cornerstone piece can establish its own ranking strength.

The identification of which older posts genuinely warrant this kind of link requires real topical relevance, not simply picking whatever posts happen to have the most existing traffic or authority regardless of subject matter. A link from an older post that's only tangentially related to the cornerstone topic reads as forced to both readers and search systems evaluating the genuine relevance of the connection, while a link from a genuinely related older post reinforces a real, coherent topical relationship.

The natural, contextual placement of these links matters more than simply adding them anywhere convenient — a link embedded naturally within the older post's existing content, where it genuinely adds value for a reader interested in learning more about the connected topic, provides more real value than the same link tacked onto a generic footer or unrelated section, which reads as an afterthought rather than a genuine content connection.

Descriptive anchor text continues to matter here the same way it does throughout topic cluster linking generally — anchor text that actually describes the cornerstone content's subject, rather than generic phrasing like "click here" or "read more," gives both readers and search systems a genuine preview of the destination content, reinforcing the topical relationship being built through the link itself, not just its mere existence.
