Link Decay

Definition

Link decay refers to the gradual loss of value and relevance of a backlink over time. As backlinks age, they tend to carry less weight in search engine ranking algorithms.

Link Decay Relevance For SEO

• Link decay can negatively impact search rankings if many backlinks to a site have rotted or lost value. Having a large number of low-quality, irrelevant backlinks can dilute a site’s overall link profile.
• Managing link decay is important for maintaining strong SEO. Tactics like link reclamation, fixing broken links, and acquiring new high-quality backlinks can help offset the effects of link decay.

Link Decay Best Practices for SEO

• Regularly audit backlinks to identify and fix broken links, redirect expired domains, and reclaim lost links. Tools like SEMrush, Ahrefs, and Google Search Console can help.
• Create evergreen content that continues attracting high-quality backlinks over a long period of time. This builds a more sustainable link profile.
• Reach out to sites linking to old or changed content and ask them to update the links or provide new relevant linking opportunities.
• Acquire new high-quality backlinks on an ongoing basis through content promotion, outreach, etc. This compensates for the diluted value of aging backlinks.
