Backlinks are links from one website to another, serving as a vote of confidence for the linked site. When a website includes a backlink to your content, it indicates that your information is valuable and trustworthy. Search engines like Google use backlinks as a key factor in determining a site's authority and ranking in search results. Having quality backlinks can improve your website's visibility and drive more traffic. Not all backlinks are equal; those from reputable sites carry more weight than links from less credible sources. Building a strong backlink profile is essential for effective SEO (Search Engine Optimization).
