The most specific searches are where a small site can win, and they sit at the bottom of every keyword export sorted by volume.
Bringing them to the top
Sort by word count, most first. Five- and six-word phrases appear together, and many of them are questions phrased exactly as a person would ask them.
Why these convert
A searcher typing six words has already narrowed their own intent. They know what they want and are close to deciding. Traffic from those terms is smaller and considerably more valuable per visit.
One page can serve many
Twenty long-tail phrasings of the same underlying question do not need twenty pages. They need one page that answers the question thoroughly and happens to match all twenty phrasings — which is also the page most likely to earn a featured snippet.
