Backlink
A link from one website to another. Backlinks act as votes of confidence that help search engines judge a site's authority.
A backlink is simply a link pointing from another website to yours. Search engines treat backlinks as signals of trust — if reputable sites link to you, your content is more likely to be seen as credible.
Quality over quantity
A few links from respected, relevant sites matter far more than many links from low-quality ones. Spammy or paid link schemes can hurt rather than help.
Why it matters
Backlinks are one of the longest-standing signals of authority in search — and that same authority increasingly influences whether AI systems trust and cite your content.
