Backlinks are hyperlinks from external websites that point to pages on your website. They play a crucial role in SEO as search engines consider them as votes of confidence or credibility for your content. High-quality link-building from both relevant and reputable websites can also positively impact your website’s rankings, signaling to search engines that the content you create is valuable and authoritative. It’s also important to focus on earning organic backlinks through valuable content and outreach, rather than simply resorting to spammy link schemes. These may even result in penalties.
