Audit Score = (Metadata Validation) + (Content Hierarchy) + (Technical Performance)
A comprehensive audit spans multiple domains: verifying Title/Meta lengths, ensuring H1/H2 cascading structure, and confirming image Alt attributes are populated.
ベストプラクティスとガイドライン
- Audit Core Web Vitals (CWV): On Page SEO is no longer just about keywords. Google heavily penalizes pages with poor Largest Contentful Paint (LCP) or Cumulative Layout Shift (CLS). You must audit your frontend loading speed.
- Verify Canonical Tags: If you have an eCommerce site with multiple URLs pointing to the same product, you must set a `<link rel='canonical'>` tag to prevent Google from penalizing you for duplicate content.
- Check Mobile Viewports: Google operates on a Mobile First index. If your page looks perfect on desktop but the text is unreadable or buttons are too close together on mobile, your rankings will plummet.
よくある質問 (FAQ)
How often should I run an SEO audit?
You should run a basic technical audit before publishing any new major piece of content, and a comprehensive site wide technical audit quarterly to catch broken links and deprecated tags.
What is an XML Sitemap?
An XML Sitemap is a structural blueprint file (usually at `/sitemap.xml`) that tells Googlebot exactly which pages exist on your domain and how often they are updated, speeding up the indexing process.
Does keyword density still matter?
No. The archaic practice of calculating 'keyword density' is completely dead. Google's modern NLP (Natural Language Processing) algorithms evaluate topical authority and semantic context, not raw keyword repetition.
