Features are the search. A hot tub, a log burner, an enclosed garden or somewhere that takes two dogs is what gets typed, and each of those phrases has far less competition than the name of the region.
Group size filters ruthlessly. Somebody organising for eight will discard every property that does not say eight, so the number belongs in the title rather than buried in a description of the bedrooms.

The off season needs its own argument. Winter weekends sell on a fire, a pub within walking distance and somewhere to dry boots — not on the same photographs that fill the property in July.
