Link insertion
Link insertion means placing a link into the body of an existing piece of content, the mechanical act behind a niche edit and most curated-link outreach.
Link insertion and niche edit are often used interchangeably, though insertion describes the action (adding a link to live content) while niche edit describes the resulting placement. The appeal is the same: an established page may already rank and have authority, so a well-placed in-content link can transfer value sooner than a brand-new article.
The strongest insertions are contextual link placements that sit naturally inside a relevant paragraph and genuinely help the reader. The weakest are links shoehorned into off-topic text purely to pass authority, which Google can treat as a link scheme. Surrounding topical relevance and sensible anchor text are what separate a durable link from a risky one.
Practical caveat: since you are editing someone else's page, confirm the link is dofollow link if equity is the goal, check the host page actually receives traffic, and avoid sites that visibly sell insertions in bulk. A page stuffed with unrelated outbound commercial links signals a paid-link operation and can become a liability worth a disavow.
