The problem with SetFocus() is that the page title will show before the page load completes. Also, IE can be customized with different titles.

You may be better off using AutoIT which can actually scrape the screen for specific text.

Are you in control of the web page content? If so, you might consider embedding code in it that could be used to notify.
