Advice is the traffic. When to plant something, what survives in shade, how to revive a lawn: these are searched far more than any product, and the centre that answers is the one visited at the weekend.
The calendar repeats exactly. Each month brings the same questions in the same order, which means a year of content can be planned once and reused with minor updates indefinitely.
Christmas dwarfs everything else on the calendar. Trees, wreaths and decorations get searched from late November, and whoever is visible in that fortnight takes the season's footfall.
Problems convert fastest. Something eating the leaves, a lawn full of moss, a plant that is dying: those searches come from somebody who intends to buy a solution today.
