Conduct technical and on-page SEO audits covering crawlability, site speed, mobile-friendliness, and content optimization. Use this skill when the user needs to improve search rankings, diagnose traffic drops, audit a website for SEO issues, or plan an SEO strategy — even if they say 'why is our traffic dropping', 'audit our SEO', 'how do we rank higher on Google', or 'our site is slow'.

SEO Audit

Framework

IRON LAW: Technical Foundation Before Content Optimization

A site with brilliant content but broken crawlability, slow speed, or
no mobile support will not rank. Fix technical issues FIRST, then optimize
content. A technically sound site with mediocre content outranks a
technically broken site with great content.

Priority: Crawlability → Speed → Mobile → On-Page → Content → Links

Gotchas

SEO results take 3-6 months: Don't expect ranking changes within weeks. Measure over quarters, not days.
Google Search Console is the source of truth: Third-party tools estimate. GSC shows actual Google data (clicks, impressions, index status).
Core Web Vitals are ranking factors: Since 2021, Google uses page experience (speed, interactivity, visual stability) as ranking signals. Not optional.
AI-generated content: Google doesn't penalize AI content per se, but penalizes low-quality, unhelpful content regardless of how it was produced. E-E-A-T matters.
Local SEO for Taiwan: For local businesses, Google 我的商家 (Google Business Profile) is critical. Optimize GBP before worrying about organic rankings.
