I was going to ask the same thing, thanks for bringing this up.
I have somewhat popular site with a useful tool that get people to search for it using widgetwidget.com. Over 70% of traffic is direct. The rest comes from google using "widget widget" or "widgetwidget.com".
The keywords are for a brand and not one of those buy widget today.com it.
So unstead of the coded title or H1 tag, which are 100-150 characters, G changed the title to keywords in domain.
I changed the title to something else. Few days later, G it to completly different keywords from the home page!
