Example AdWords campaigns on my website

This is for my IT382 Digital Marketing module.

This proposed AdWords campaign is for my website: nowtweet.it . The website is a URL shortener optimised for Twitter. Looking at the keywords and discription, I have proposed the following two AdWords Adverts:

Shorten those long URLS
Use Twitter? Shorten your URLS
the simple way with Now tweet it
nowtweet.it

Free Twitter URL Shortener
Nowtweet.it is the best way to get
your long URLs into Twitter!
nowtweet.it/shortenURL

Proposed Keywords: Twitter, URL, shorten URL, shrink URL, tweet, tweet URL, post URL, Twitter tool, free Twitter tool

The estimated search traffic that the Google tool shows is fairly low, but with a limited budget it should be adequate. The campaign can be monitored based on average costs per click and will be shown in countries where Twitter is commonly used; for example the UK, USA, Brazil and Canada.
