Analyses outbound links for dofollow/nofollow strategy, domain diversity, anchor text quality, and sponsored/UGC attributes. Use when auditing link profiles or optimising outbound linking strategy.
Audits HTML patterns that affect Core Web Vitals (LCP, CLS, INP). Checks for layout shift causes, largest contentful paint blockers, and interaction responsiveness issues. Use when optimising page performance or fixing Google PageSpeed Insights warnings.
Validates hreflang tags, multi-language configuration, regional targeting, and internationalisation best practices. Use when auditing sites with multiple languages, regions, or localised content.
Validates title tags, meta descriptions, Open Graph tags, and Twitter Cards. Use when auditing or fixing meta data for search engine and social media optimisation. For canonical URLs and robots directives, see the technical-seo skill.
Validates viewport meta configuration, responsive design, font sizes, touch target sizes, and mobile-hostile patterns. Use when checking mobile-friendliness or fixing mobile rendering issues.
Validates heading hierarchy, keyword density and placement, and internal/external link structure. Use when auditing on-page SEO factors for an HTML page.
