To make your website SEO friendly, you must focus on both on-page and off-page SEO. On-page SEO involves optimizing elements directly on your website. You should start with keyword research and use relevant keywords in titles, headers, and content. Ensure your website is mobile-friendly and loads quickly. Properly structured URLs and internal linking also improve navigation. Off-page SEO focuses on external factors that impact your ranking. You should build quality backlinks from reputable websites. Social media engagement and brand mentions also boost your website's authority. Combining on-page and off-page SEO will improve your site's visibility and ranking.
