Backlinks are links from one website to another. In SEO, they matter because they act like signals of trust. When another website links to your page, it is essentially pointing readers toward your content and saying, "This is worth checking out."
Search engines use
get backlinks as one way to understand which pages are helpful, credible, and relevant. A website with strong backlinks from
respected sources may have a better chance of ranking well than a site with no outside references. But not all backlinks are equal. A link from a trusted industry blog, news site, university, or popular resource page is usually much more valuable than a link from a
low-quality spam site.

The best backlinks are earned naturally. This happens when you publish content people actually want to reference, such as guides, reviews, original research, comparison articles, tools, tutorials, or useful resources. For example, a detailed guide that answers a common customer question can attract links from bloggers, forums, small businesses, and other websites in your niche.
