There are many SEO companies that offer training programs. In addition, some universities and institutions offer certificates in Internet Marketing or Internet Programming. However, the principles behind Business Management and Marketing are similar to Internet Marketing. That said, a conventional marketer cannot be successful in internet marketing without extensive knowledge and research of the ‘net.

So I would recommend you to visit seomoz.org, and other similar SEO blogs and websites, and read all of their articles, read their blogs, take their quizzes and tutorials. At the same time, a certificate in Internet Marketing or a Bachelor’s in Business is helpful to make you successful – but many successful Search Engine Optimizers and Marketers did not have any of these credentials, they learned from real life experience.

I did a certificate in Internet Programming and I won’t say it wasn’t worth it, but it was very expensive and in hindsight I shouldn’t have spent that much money on it. Be very careful of fraud schools like CDI.

try Brainbench tests and tutorials, i think they have lots of stuff to learn from
