I'm occasionally doing that and especially suggest non-technical users to do exactly this thing. I can mistype URL. Google will correct me, if site is well-known. Otherwise I'm risking to go to phishing website.
I just finished helping out a friend who did exactly this thing, clicked on an ad at the results page thinking it was Google's top result and was redirected to an ESTA scam site where they lost a bunch of money.
What's easier to tell apart for nontechnical users? URL bar from Google search field or ads from Google results?
