Long-tail keywords
Specific, multi-word queries with lower individual volume but clearer intent.
What it means for a site you run
Long-tail queries convert better because the searcher knows what they want, and they are where small sites compete: the head term is owned by giants, the long tail is wide open. A blog's job is largely to farm the long tail around its product.
