Are these articles free to use on other websites or are they copyrighted for wikipedia only ? Mostly, i dont even see the author of an article. Anyone know more about this subject ?
What's best about Wikipedia is that you can exploit its high-ranking pages by becoming an editor of Wikipedia and submitting useful content to it and then adding a link to your website in a Wikipedia entry related to your website. I did it before. But you have to make sure that the site you're linking to in that Wiki entry is relevant and very useful to the purposes of people reading that Wiki entry, of course.
