Yahoo's "Explore Concepts"?

New to me!

[Reno]

One of my sites is about a topic that on average gets very little daily traffic. However a few days ago, Yahoo sent over a thousand visitors for one 5 word search query. At first we thought this was some sort of automated program that was out of control, but in looking at the stats, it was in fact 1007 unique visitors on the same day, spread over the full range of IP numbers, all from Yahoo, all with that exact same 5 word query.

I was perplexed until I dug deeper, then found that Yahoo is doing something called "Explore Concepts:", which is new to me. If you put in a short query, then this "Explore Concepts:" box came up at the top of the SERPs, with the 5 word phrase as the first choice. That longer phrase is what the 1000+ visitors clicked to reach our site.

I do like it and hope it is continued/expanded, but am feeling as if I've been asleep at the wheel, as I've not seen it before :~}

How long has this been going on?
