This document discusses various types of off-page SEO techniques, including social bookmarking, blog directory submissions, image submissions, video submissions, and question and answer submissions. Social bookmarking allows users to share and bookmark web pages on social sites to help spread knowledge. Blog directory submissions involve choosing relevant categories to build quality backlinks over time. Image and video submissions require optimizing the media with proper titles, descriptions and tags before sharing on submission sites. Question and answer sites are a good way to get traffic by providing helpful answers to related questions and including links to one's website.
