Search engine optimization or SEO is a methodological analysis of strategies, techniques, an approach used to increase the number of visitors to a website by determining a top-ranking placement in the search results page of a search engine (SERP) — including Google, Bing, Yahoo, and other search engines. SEO is generally used to grow up your business. SEO is about to upgrade a website by boosting its presence in search engine results pages (SERPs). Usually, you cannot simply develop a website with ill-organized and out of date content. It would hardly be of any use. In other words, SEO involves establishing certain changes to your website design and content that makes your site more attractive to a search engine.
