What Are Backlinks?
Backlinks are links from other websites that point to a page on your site. They function as a signal of trust and relevance — every backlink is effectively one site vouching for another.
Why They Matter for SEO
Backlinks remain one of the strongest ranking factors search engines use, on the logic that pages other sites choose to link to are more likely to be genuinely valuable. A site with many high-quality backlinks tends to rank better than an otherwise similar site with few or none.
What Makes a Backlink High Quality
Quality depends on several factors: the authority and trustworthiness of the linking site, how topically relevant it is to your content, whether the link is dofollow or nofollow, and whether it was earned naturally rather than paid for or manipulated. A single link from a highly relevant, authoritative site is typically worth far more than dozens of links from low-quality or unrelated ones.
