SEO relies on four main tenants. It all starts with search engine optimization techniques, which means that search engines can easily access and index your information. Satisfaction is the second cornerstone. If your website ranks well in search engines, you must ensure it has the most relevant material concerning keywords and search queries. On-site search engine optimization is the third pillar, and it entails doing things like writing and laying up your site in an effective way. Off-site optimization strategies, such as link building, are the fourth pillar of search engine optimization. Getting other websites to link to yours is called "link building."
