Limits and human review

The skill cannot reliably detect structured data or schema markup using only `web_fetch` or `curl`, as these tools strip client-side JavaScript. It also requires the user to provide context on site type, business goals, and current traffic levels for a complete audit.

Words, phrases, and punctuation patterns commonly associated with AI-generated text. Avoid these to ensure writing sounds natural and human.

## Em Dashes: The Primary AI Tell

**The em dash (—) has become one of the most reliable markers of AI-generated content.**

Em dashes are longer than hyphens (-) and are used for emphasis, interruptions, or parenthetical information. While they have legitimate uses in writing, AI models drastically overuse them.

### Why Em Dashes Signal AI Writing
- AI models were trained on edited books, academic papers, and style guides where em dashes appear frequently
- AI uses em dashes as a shortcut for sentence variety instead

## Hreflang

### Placement Methods

Google supports three equivalent methods: HTML `<link>` in `<head>`, HTTP `Link` headers, and XML sitemap `<xhtml:link>` elements. Google confirmed no method is prioritized over another.

Google combines signals from both HTML and sitemaps. If the same language-region pair points to different URLs across methods, Google drops that pair rather than guessing.

### Reciprocal Requirement

Google's docs: "If page X links to page Y, page Y must link back to page X. If not, those annotations may be ignored or not interpreted correctly."

Every page must include itself (self-referencing) in the hreflang set. Missing self-referencing is the #1 error found by Semrush audits. A study of 374,756 doma

# SEO Audit

The same skill in the words people use speaking to an assistant rather than typing into a box. Each one carries the situation it came from, and each answer says only what the skill's own files support.

asking about SEO issuesI need help with my SEO, what should I do?

This skill acts as an expert guide to identify and recommend improvements for your site's search engine optimization. It covers everything from technical foundations like crawlability to optimizing content and handling international settings.

international SEO concernsDo I need to worry about my hreflang setup?

If your site serves multiple languages or regions, you must check for self-referencing entries on every page and ensure reciprocal links are in place. Using the correct ISO codes is also critical.

technical SEO questionsCan this skill find my schema markup?

No, because `web_fetch` or `curl` cannot reliably detect structured data / schema markup. You must use a browser tool or Google's Rich Results Test for accurate findings.
