To make money online this is what you need to do.

You'll need to choose a niche and find out if people are searching for things that are related to your niche on the Internet by checking on keyword search terms used on search engines.

You'll need to choose a target group(s) to sell to in your niche. You'll need to determine the right products/services to sell to targets in the niche, you can do this if you know the targets in your niche, what they want, the problems they have and the solutions to them, what others are giving them, and the highest value they should have in the niche. You'll also use this knowledge to create/write the ads, content and free giveaway that sell in the niche for your promotions.

Once you've determined the right products/services to sell in your niche, you'll need to find out where your targets are online so that you'll promote to them to make the sale, this is where PPC (pay-per-click) comes in.

To make money online you'll have to sell on targeted ad media to make the sale, targeted ad media is where you can find and reach the targets who'll buy from/through you, selling on untargeted ad media will not make money.

These ad media/techniques have made online marketers lots of money again and again over the years – ezines, articles, forums, affiliates, search engines, PPC (pay-per-click) services like Google Adwords and joint ventures.

Obviously it is not only PPC advertising that can make you money on the internet, the fact that you don't know PPC advertising does not mean you'll not make money online, all you need is to get to targets who'll buy from you through other types of ad media if you cant for one reason or the other use PPC advertising.

PPC is just another technique/method of advertising, if you don't have the right products/services to sell and you don't know who (the targets) you'll sell them to, no promotional technique/method will work, no matter how popular it is, hence you must know your niche and targets and what they want to make money on the internet.
