Sometimes you make the best sale when you aren't trying to sell! Educational content (for altruistic purposes) can be an informative and/or entertaining "gift" to the public. Keep the spirit of generosity alive on the internet. You've found information about subjects on the web… return the favor and share some of yours! People might end up bookmarking your site, and referring other people to it. That'll generate activity which stimulates the interest of the web bots.
DMOZ (Directory Mozilla) is a multilingual, open content web directory listing sites that are not only for commercial purposes. Only websites containing educational content are accepted. These submissions are then fed through to Google and Yahoo, potentially increasing your site’s visibility to the web crawlers, thus helping its placement with the search engines.
- extra content and files on a business’ website increases its chances of being found by the web visitors via the search engines
