If you are a local business then it might be a good idea to try using Google AdWords Express. Google AdWords Express means that your ads will appear inside Google Maps across all types of device, be it mobile phone, laptop, desktop pc, tablet etc. and will also appear on related sites inside the US. In addition your Google Plus profile will be used as a guide to match your business to relevant searches.
Using Google AdWords Express you won’t be able to control what keywords there are but you can see the keywords that Google has selected for you and you will not need to manage your ad campaigns as Google makes it easy.
The other advantage is that you don’t need an actual website as you can simply use your Google+ page.
