Competitive Analysis with Excel

I am currently trying to create program in excel with a form that will allow the end user to input a website's URL, and excel returns with the url in "A1", html meta keywords (unparsed) in "B1", meta title from html page source in "C1", and html meta description in "D1". I am unfamiliar with ie automation but am familiar with building forms and I am currently using Excel 2007. Userform name - frmComp Command Button name - cmdGo Textbox name - txtUrl
Can anyone please help?
