Quite a few site owners have complained about Google's "Direct Answers" (a.k.a. "Knowledge Graph" boxes), which they think will deprive of them of traffic by answering searchers' questions on the SERPs.
In some cases, at least, that threat may be overrated.
Here's an example (and I'll use a real one, just to test the temporary change in this forum's TOS):
I did a search on "doughnuts" a few minutes ago, and the resulting SERP had a huge Direct Answer box with a photo of doughnuts, a dictionary definition of "doughnut," and a long list of "Nutrition Facts" for "doughnuts, with chocolate" from the USDA. For the searcher who might be looking for information on making or buying doughnuts, the Direct Answer box was essentially a waste of space. It seemed to exist mainly a technical showpiece, as in:
"We've figured out a way to mash up photos, dictionary definitions, and USDA information in food searches. Isn't that cool?"
Obviously, there are cases where Google Direct Answers may take away casual traffic (people wanting to know the capital of North Dakota or whatever), but for at least some searches, Direct Answers and the Knowledge Graph are little more than fluff.
