Find website Information

I have been given task to check for url that

1. site:domain (If index in Google)

2. link:domain ( If any backlinks)

3. keyword (in domain)

Can anybody give me idea how to implement it.So far for 1 I think i should search google for the KW site: your site.com and see if it is listed in the results or not.

2 and 3 are still unknown.

A开发者_StackOverflow中文版ny help would be great.

I have to use c# winforms or WPF.
