On Site Search Engine Optimization or On Site SEO refers to everything used or contained within the site itself. It would include all the pages with the On Page SEO techniques applied, as well as site specific techniques, files and requirements that are used by a search engine algorithm to place your pages in its index. This includes both visible and invisible elements. This also includes site size, navigational methods, sitemaps and other site SEO related issues.
