Long-tail referrals from Google have always tended to be poorly targeted in comparison to shorter search terms. To some extent, this is probably unavoidable. It might be interesting to see if bounce rates on long-tail referrals improve as a result of Hummingbird. Except that it's hard to separate long-tail traffic from short-tail traffic if referral data isn't being provided.
