This document discusses the key pillars of SEO, which include website accessibility and prominence on search engines. Website accessibility involves on-page SEO like keyword research and technical elements, while website prominence relies on creating and promoting great content both on-site through blogging and off-site via social media and links. The goal is to send signals to search engines like Google that your website deserves high rankings by having engaging, shareable content that keeps users on your site. Great SEO combines technical optimization, creative content marketing, and social promotion to improve organic traffic from search.
