Search Engine Marketing is all about getting traffic to your website using paid placements in SERPs (search engine results pages).
Usually this means pay-per-click advertising such as Google Adwords.
As the market is still maturing, pay-per-click is relatively cheap. It will not stay this way forever, so start now!
To set up an effective online business you will need the following:
- A search engine optimised website, preferably a content management system such as Wordpress.
- A pay-per-click marketing campaign.
- Effective means of managing sales leads and email campaigns.
