Pay per click to advertise?

[Boomer]

If you want to advertise your business with Google and you select Pay Per Click,(PPC) you will pay Google each time a unique IP or visitor, clicks the ad you are advertising. The amount you need to decide on should be based on how many visitors you can expect to get. A rule of thumb is if you are going to pay, let's say, 1 penny per click and you expect you will have 3000 visitors, you should budget 1.5 times the amount of traffic you can expect. In this case would be $45. This is a low ball example but you should budget based on what you can afford against what amount of traffic you expect to have visit your site. This can be costly but If you find that PPC gets to costly, you can change your plan but that'll impact the SEO Google does when it promotes your site.
It really matters how much you budget because if you don't sell a product to get an ROI, you could wind up spending a lot of money.
