What it does
Once installed, the agent checks a website's hreflang tags, which tell search engines which language or regional version of a page to show to which users. It looks for common mistakes such as missing return links, invalid language or region codes, non-canonical URLs, and mixed HTTP/HTTPS, and it can generate correct tags for HTML, HTTP headers, or sitemaps. It also notes region-specific search features where relevant.
Great for
- SEO specialists working on sites with several languages or countries
- Developers implementing multi-language sites who want correct hreflang markup
- Agencies auditing a client's international search setup
Skip it if
- Sites with only one language and no regional versions, since the skill adds little value there
- Anyone expecting guaranteed ranking changes; hreflang is a hint and the skill's guidance is based on documented rules, not a promise of results
Try asking
- “Audit the hreflang tags on https://example.com and list any missing return tags”
- “Generate hreflang link tags for my English, French and German pages”
- “Check whether my language codes like en-uk or jp are valid hreflang values”
- “Create an XML sitemap hreflang block for my cross-domain .com and .de sites”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Give the skill the full URL or a list of page URLs so it can check the full set of alternates.
- Provide the canonical URLs for each page, since hreflang on non-canonical pages is ignored.
- Verify the generated output against the live site, because the skill works from the content you provide and fetching pages depends on the agent's own tools.
