This is a Smart Move
Using PPC gives you numerous advantages. The most important is that you only get to pay for traffic driven to your site. Using this method you also get traffic as a result of a wider exposure of your site on the web. This method also allows you to control how much you spend on advertising.
This is because you can tell when you are doing well and when you need to advertise. In actual sense you can monitor the effect of advertising.
But you need to be careful
You should be wary of PPC search engines that pay clickers to click their revenue from clicks. You may find yourself paying for 10 clicks that came from a single person who never bought anything. You should therefore steer clear of unscrupulous search engines.
