What are Backlinks in SEO?
Backlinks, also known as inbound links or incoming links, are links from one website to another. In SEO (Search Engine Optimization), backlinks act as votes of confidence from other websites, signaling to search engines like Google that the linked content is valuable, credible, and relevant. Websites with high-quality backlinks tend to rank higher in search engine results pages (SERPs) because they are perceived as authoritative and trustworthy.
Backlinks, also known as inbound links or incoming links, are links from one website to another. They serve as a signal to search engines that your content is valuable and credible. When a reputable website links to your page, it acts as a vote of confidence, indicating that your content is worth referencing. Backlinks are essential for improving search engine rankings, as they help search engines determine the authority and relevance of a webpage.
For example, if a popular blog links to your website’s article, search engines consider it as a recommendation, which can improve your website’s ranking.
