Do you want to rank high on Google ?
Search engine optimization (SEO) is the process of improving the visibility of a website in search engines via the (“organic” or “algorithmic”) search results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine’s users.
SEO may target different kinds of search, including image search, local search, video search, news search and industry-specific vertical search engines.
