I think there is an under-appreciated average search engine user in the comment:
People will typically write their intent on the search engine even when they could simply directly to the website.
Case in point: The top 10 bing searches are for websites, including FB, Google, Youtube [1]. This traffic is highly competitive and should (as in all competitive markets) be bid among competitors.
The address bar is the search bar. My wife never types "facebook.com". She types "facebook", gets the google search page, and then clicks on facebook from there. It pisses me off that if I start typing facebook, Chrome doesn't autocomplete to facebook.com. In contrast, if I'm in Safari, and type "n" I get "news.ycombinator.com" autocompleted.
Small business people in my area of UK have always done this, type in the box in the middle (usually Google, occasionally Bing or some other service). But my pretty tech-literate kids do it too, even when I show them how they 'should' do it and that is faster, and they don't need the extra click to get where they're going ... mad!
On Chrome on Win10 as I use at work though, typing in the address bar, with my settings, I get auto-fill of addresses (the history search is noticeably missing vs Firefox) including the option to use 'tab to search' on a domain.
