Where are the South African Internet Marketing and SEO companies?

It seems to me that South Africa is a few years behind the rest of the world when it comes to the internet. I represent a South African Internet Marketing and SEO company, and 85% of the companies we represent are not South African companies. It seems to me that South African companies still do not know how the internet can increase their business sales and revenue and provide the highest return on investment.
i would like to know your comments.
