Though it may seem counter-intuitive because you are paying per ad click, paid search advertising can actually be budget-friendly. This makes it an ideal tactic for small businesses that are working with a limited budget. Since you are able to target specific types of consumers and measure every aspect of your campaign along the way, there are plenty of ways to optimize your budget and boost ROI. You can set budget caps, and the search engines will not spend more than you tell them to.
