## Use cases

- Investigate technical indexing problems
- Review canonical and hreflang on a bilingual site
- Prioritize fixes after a site migration

## Outcome

An audit recording each issue, its evidence, impact and proposed fix.

## Example task

Audit this RU/EN site for indexing, canonical URLs, hreflang, sitemap and internal links. Give a URL and evidence for each finding; do not invent explanations for rankings.

## Requirements and limitations

agents:
- An agent that can read Agent Skills instructions; tool access depends on the host

tools:
- Browser or crawler that can inspect rendered pages
- Search Console for indexing and traffic evidence; PageSpeed Insights as needed

keys:
- Site-owner access for private Search Console data

paidDependencies:
- Ahrefs, Semrush and other commercial crawlers are optional

limitations:
- Rankings and traffic gains are not guaranteed.
- Validate structured data in rendered output; text-only fetches may omit scripts.
- Some upstream tool references are dated, including the retired Mobile-Friendly Test; use current equivalents.
- Editorial selection based on source inspection, not a comparative performance certification.
