Backlinks are links from other websites that point to your website. Search engines often treat them as signals of trust and authority, especially when the linking site is reputable and the link is placed in relevant context. In practical terms, backlinks help search engines discover your pages and can influence how strongly your content is viewed compared to similar pages on the same topic.
What matters most is quality and relevance, not just the number of links. A backlink from a credible site in your industry that naturally references your page is typically far more valuable than dozens of links from unrelated, low quality directories. Aim for links that support accurate information and add real value for readers, such as citations, resources, partnerships, and press coverage. Avoid manipulative link schemes, since they can create confusion, undermine credibility, and put your site at risk of penalties.
