Is a Survey by Google Legit?

Episode 1577 (1:42:30)

David from LA, California
Google

David received an email from Google asking if he'd participate in a media use survey. Is it legit? Leo says to look at the web address. Hackers are very good at spoofing emails. He wants to see the top-level domain of google.com/restoftheurl. If it's google.somethingelse.com then that isn't legit.
