The internet presents a lot of interesting opportunities to make money. If you already have products of your own then simply setting up an e-commerce website and sending traffic to your site that is targeted is the key to getting more sales. Pay per click advertising can often be a good way to get relevant visitors to your site. Some good ones include Google AdWords and Bing search marketing. Use targeted keywords in your pay per click campaigns where you are going after potential buyers and not just people looking for information.
Tracking is key:
It is important to ensure that you are tracking conversions closely as optimization is very important where you want to bid more on keywords that are converting and remove keywords that are not converting.
