Good catalog architecture is rarely invented from scratch — it's usually borrowed from a player that already figured out how to spread demand across sections and landing pages to catch both broad and narrow queries. Walking a competitor's whole structure by hand, filter pages included, takes too long to do properly.
This skill walks a competitor's site from the homepage down into its key sections, rebuilds the structure as a tree, and flags which decisions — dedicated landing pages for narrow demand, filter pages acting as standalone SEO pages — are worth borrowing for your own architecture.
What it does
Given a competitor's site (and your niche, for sharper findings), the skill studies the homepage navigation, then two or three key sections to see how subcategories, filter pages, and internal linking work, and checks via search which of the competitor's pages Yandex treats as authoritative for its main topics.
What you get
A chat report with a text-tree map of the structure — section, subsections, page types — plus notable findings like landing pages for demand most competitors miss, and three to five specific structural elements worth adopting, each with a note on the demand it captures.
