The season is short and badly timed. Everybody searches in the first hot week, by which point the manufacturing diary is full, so the pages that convert are the ones read in February by somebody planning ahead.
Cost is the first search and it goes unanswered. A range by width and projection, with what changes it, brings in the people who assumed this was far more expensive than it is.
Repairs are the quiet, reliable half. A torn cover, a failed motor or a recover on an existing frame happens all year and competes with almost nobody.
Terraces and shopfronts are a bigger market with different words. Cafés extending outdoor seating are buying trading capacity, and they search for that rather than for shade.
