The largest thing with buying web traffic from Google is you often don't know what your profits will be until you have maxed out your credit card and realize you're going to go broke. That is why I want to show you the right way to figure out how much money you can make so you can avoid this disaster.
How Come It's Hard To Tell How Much Money You Are Going To Make:
The problem with AdWords is the fact that you can't tell how much money you will make until you buy a bunch of clicks. So what most people do is stick their head in the sand and hope for the best. Not only that, they think that somehow if they just spend enough money that they will eventually make a profit.
They subconsciously think that Google will feel bad for them and give them cheaper clicks because they have blown every penny they have!
Here Is How Know The Profits Before Blowing All Your Cash:
The thing you need to do is find a site in your market who is using AdWords the right way and is selling what you want to sell. That way you can use that person as a model as they are obviously profitable and know what they are doing.
Don't rip them off - but use the model they are using. Then focus on getting visitors from only the keywords that make sense and that will bring buyers. Once you get profitable doing this - then roll it out on a big scale.
