Features
ZHS Site Audit and SEO Diagnostics divides your site’s health into four core strategic pillars across 17 automated checks:
1. Usability Diagnostics
- HTTPS & SSL Transport Security: Checks active SSL protocol enforcement and detects Strict-Transport-Security (HSTS) headers.
- Mobile Viewport Optimization: Validates responsive <meta name="viewport"> attributes and flags accessibility-blocking parameters like user-scalable=no.
- Multi-Channel Contact Options: Scans for clickable tel: links, mailto: links, social profiles, and interactive contact form blocks.
- Entry Popup & Interstitials: Detects invasive overlays and verifies accessible dismiss controls to safeguard mobile page experience scores.
- Footer Trust & Legal Links: Validates Privacy Policy, Terms of Service links, and flags dead # dummy anchors.
2. Accessibility (WCAG 2.4.1 Standards)
- Skip-to-Content Navigation: Checks for bypass navigation links and confirms their target IDs exist in the DOM.
- Image Alt Text Diagnostics: Audits images for missing alt tags, junk filenames (e.g. IMG_001.jpg ), and redundant title mirrors.
- Form Input Labels: Verifies that form inputs have explicit <label for="..."> pairings or ARIA labels.
- Heading Hierarchy (H1-H6): Enforces a single H1 tag, prevents skipped heading levels, and flags empty heading tags.
3. SEO Essentials
- HTML Title Tag: Assesses SERP character length (optimal 50-60 characters) and flags default WordPress taglines.
- Meta Description: Evaluates SERP preview snippet length (optimal 140-160 characters) to maximize organic CTR.
- Canonical & Robots Indexing: Validates self-referencing canonical tags, inspects noindex flags, and checks search engine visibility.
- Open Graph & Twitter Cards: Ensures social preview cards ( og:image, og:title, twitter:card ) render correctly when shared.
- XML Sitemap Reachability: Probes core WordPress and SEO plugin sitemap endpoints ( /wp-sitemap.xml, /sitemap_index.xml ).
- Indexable Content Depth: Analyzes front-page text density and calculates database published content volume to prevent thin-content penalties.
4. GEO & AI-Readiness (Search 2.0 / Knowledge Graphs)
- Schema.org JSON-LD Structured Data: Deep-parses JSON-LD graphs for Organization, LocalBusiness, physical addresses, and sameAs entity authority profiles.
- AI & Entity Brand Readiness: Audits brand consistency across site titles, Open Graph tags, Schema entities, and copyright notices for LLM search indexing.
