Technical problems rarely stay isolated: slow load times amplify indexation issues, and pages blocked from crawling skew what Webmaster reports. Seeing that connection requires looking at several data sources at once instead of one problem at a time.
What it does
Given a site address — and optionally two or three key pages — the skill checks four areas in sequence: crawlability (robots.txt rules, sitemap coverage, noindex tags, canonicals), Core Web Vitals on the homepage and any specified pages, how fully the site is represented in the Yandex index, and excluded pages plus crawl errors from Yandex Webmaster's diagnostics.
What you get
A document saved to your library: a three-to-five sentence summary of site health, a section per area with statuses and findings, and a consolidated work plan where each action carries an expected effect and priority (high, medium, low). Chat gets only a short digest — up to eight lines covering the overall verdict, the top three problems, and where to start. This needs a connected Yandex Webmaster site; without it, the crawl-error and exclusion data is missing. Run it as a recurring quarterly or half-yearly check, when handing a project to a new specialist, or before a major investment in promotion.
