A short answer is yes! Adding an additional campaign will generate more leads, and is good for your business overall. It increases the exposure of your business page and branding, as more people have a chance to click on it and see who you are. It also allows you to test different markets and see where you should be focusing on. When you are running 2 or more ads, you can compare which one is performing better and this will indicate where you should be spending your advertising dollars.
