We are scraping from here: https://adwords.google.com/o/KeywordTool
We have a tool similar to this: http://legitseo.com/wp-content/uploads/2012/04/ultimate-niche-finder-review.png
Source code is in C#.
1. User inputs Adwords account in settings window. This removes captcha.
2. User inputs phrase(s) in our program.
3. User inputs CPC, search and other filter data.
4. Keyword ideas from Google keyword tool are populated into the C# tool.
Right now, HTTPWebRequest requires constant updates to a selectors.txt (attached) file after every Google change. Your job is to either automated the creation of selectors.txt or change it to WebBrowser.
