[Veronica]

The best and most cost effective way to market on the Internet will depend on what you are trying to sell, where you are trying to sell it, and who you are trying to reach.

The top three ways of marketing online include:

a) search engine optimization (SEO) b) pay-per-click marketing (PPC) c) email marketing
Social Media Marketing, Video Marketing, and Mobile Marketing are also increasing in popularity as web based marketing tactics.

On the list above, if you have the time and knowledge required to optimize a site, SEO is likely the most cost effective as the results typically are long lasting and continue to drive traffic for an extended period of time.
