Web browser bookmarks assist with navigation and remembering pages, whereas social bookmarking lets one post pages to a public domain and tag them with keywords. This helps others to locate the sites when looking for subject matter relative to the keywords. This can produce traffic for pages, where if they had not been bookmarked, might not have been as conspicuous. Initially, to attract traffic and quality backlinks one needs to inform people that a site actually exists. It is useless to depend on people finding you via search engine rankings. Users can search many site pages for specific topics and bookmark a page themselves. This demonstrates to an interested audience that a particular site is real and also promotes recognition. Social bookmarking can be utilised to give popular subject matter on a site more exposure and even assist sites to go viral.
