Website promotion is the continuing process used by webmasters to promote and bring more visitors to a website. Many techniques such as web content development, search engine optimization, and search engine submission, are used to increase a site's traffic.
Search Engine Land created an infographic of factors that affect ranking in search engines for search engine optimization that help drive traffic to a specific website.
Search engine optimization (SEO) is the process of affecting the visibility of a website or a web page in a search engine's "natural" or un-paid ("organic") 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.
