<p class="MsoNormal">Search engine optimization consists of several core types, including on-page SEO, off-page SEO, technical SEO, and local SEO. On-page SEO involves optimizing elements like keywords, titles, and content on individual pages. Off-page SEO focuses on building backlinks from reputable sites to boost domain authority. Technical SEO ensures your website loads quickly, is mobile-friendly, and is easy to crawl by search engines. Local SEO targets geographic-specific searches, making it essential for businesses serving a local community or region.
