I need a reliable solution to extract data from the Google Adwords Keyword Tool ([url removed, login to view]).
The Information that will be passed to the script:
-Name of the Keyword (for example: car insurance)
The information that should be extracted from Google:
-search volume per month (for example: 12000)
-estiminated CPC(Cost per Click) (for example: 1.96€)
That's all. No captcha breaking required, I can input it by hand. Although I would be impressed if you could break it.
There's no need for a userinterface, just a php function getdata($keyword) that returns search volume and cpc.
The Script has to handle about 500 Querys per hour.
