Pay per Click does exactly what it says on the tin. You pay every time someone clicks on your ad.

With pay per click, you're paying for a keyword and keywords vary in price. Some are very expensive - "mortgages", "dublin hotel", "conference hotel". Others aren't as expensive. It all depends on which industry you work in.  

Part of this service is that you'll get advice on the best way to use your budget, however big or small it may be. Your campaign will be set up for you and you'll receive weekly and/or monthly reports on your campaign performance. Do you have last minute hotel room rates you want to advertise? Maybe a special offer that ends in one week? Or are you a start up with a brand new website that isn't appearing in Google yet?

PPC offers instant visibility and instant results in Google, using a controlled budget so your costs don't spiral out of control.
