It is amazing how so many people have tried out the best online advertising methods and yet still never really realized its' true potential. Meaning that it still stares them in the face and they cannot even recognize it.
There should really be no debate about this so let us look at your own habits online. When you require some information online, where do you go? To your favorite search engine naturally, where you key in some relevant keywords. The results will depend on the content available online concerning the subject that you are interested in.
So it is highly unlikely that there is a more effective online advertising method than using promotional articles to attract the attention of leading, popular search engines. Why then is it that there are so many people who have tried promotional articles and it has not worked out too great. The answer to that question is simple. Writing a few articles and posting them at article directories will hardly do much for your traffic. Promotional articles are meant to be visible online and for this to happen, you must understand search engine optimization or SEO. This means that you must post article designed to generate lots of one way links pointing to certain key, quality articles at your site. The most efficient way of getting this to happen is writing quality articles that other webmasters will quickly pick up and re-post at their sites complete with the carefully chosen anchor text links in the author's resource box at the bottom and also within the article.
Relevant classified ads can also be pretty effective, especially when people who know what they are doing do it.
