Small changes can make a big difference to this issue, I think. If you've ever written about piracy you might have noticed a lot of unrelated hits from people searching for torrents of the work of anyone you happen to mention. I have. However, ever since Google stopped suggesting torrents and other related words, this incidental traffic slowed to a trickle.
