Here is a list of every social bookmarking website on the web that is worth bookmarking and then a few more!

Social bookmarking websites are one of the fastest growing web services online. They allow you to save and organize bookmarks online instead of saving them in your browsers “favorites” list, which helps better organize them and remove the endless list of bookmarks in your browser.

Search engine ranking specialists or SEO specialists can use this list by creating accounts on each of the social bookmarking sites below and submitting client's websites. Submitting websites to social bookmarking websites allows the websites to be easily crawled by search engines. Many website owners pay for this service or do it manually themselves.
