Good morning. I write a lot of original content on sports, a soccer team in the UK that is. Now I read that if my content is published on another website/blog and the article contains a link back to my website, that will help my PR a lot. What exactly is this system called, is it backlinks? And how does it work exactly? That is, to have my articles on other websites/blogs with links back to my website, do I have to pay or it's the other way round? Thank you.
You submit your articles to certain sites. The term is "article marketing" and you can do some more research on that. One such site is ezinearticles.com, but I know there are a plethora of similar sites.
