A site-wide audit is good for the big picture but poor at pinpointing one struggling section — a product category that's lost rankings, or a blog that's clearly underperforming. Those problems get buried among hundreds of other findings in a general report.
What it does
Given a section URL — a category, blog, or service area — the skill checks three things at once: whether the hub page itself is structured properly, how much of the section's child content actually makes it into the Yandex index, and whether key pages in the section load fast enough.
What you get
A compact report scored across three axes — structure, indexation, speed — each with a clear status, plus a prioritized list of fixes. It closes with one line naming the single change that gives the biggest payoff for the least effort in that section. Use it whenever one part of the site underperforms while the rest looks fine, before launching a new category, or as a recurring check that walks through sections one at a time instead of drowning in a whole-domain report.
