Meta Tags Analysis
Ensure your pages are fully optimized for search visibility. We analyze every meta tag that Google and social platforms use to understand and display your content in search results.
- Title tag length and keyword optimization (30–60 characters)
- Meta description length and compelling copy (70–160 characters)
- Canonical URL validation to prevent duplicate content
- Open Graph tags for Facebook, LinkedIn, and social sharing
- Twitter Card meta tags and social preview optimization
Performance & Core Web Vitals
Measure the exact metrics Google uses to evaluate page experience. We run Lighthouse audits for both mobile and desktop, and pull real-user data from Chrome UX Report when available.
- Largest Contentful Paint (LCP) — how fast main content loads
- Cumulative Layout Shift (CLS) — visual stability of your page
- First Contentful Paint (FCP) and Time to First Byte (TTFB)
- Speed Index, Total Blocking Time, and Time to Interactive
- Lighthouse scores for Performance, Accessibility, SEO, and Best Practices
Technical SEO Audit
Verify the technical foundation that search engines need to properly crawl and index your site. We check server configuration, security headers, and crawlability essentials.
- HTTPS encryption and SSL certificate verification
- robots.txt validation and crawl directive analysis
- XML sitemap detection and format validation
- Security headers: HSTS, CSP, X-Frame-Options, X-Content-Type-Options
- www/non-www redirect consistency check
Mobile Optimization
With Google's mobile-first indexing, your mobile experience directly impacts rankings. We verify every aspect of mobile readiness.
- Viewport meta tag with correct device-width configuration
- Touch target sizes and spacing for finger-friendly navigation
- Base font size verification (minimum 16px for readability)
- Responsive design detection and horizontal scroll prevention
Content Structure
Well-organized content helps both search engines and users understand your pages. We analyze heading hierarchy, text quality, and image optimization.
- H1 heading presence, uniqueness, and keyword relevance
- Heading hierarchy validation (H1 → H2 → H3 without skipping levels)
- Image alt text coverage for accessibility and image SEO
- Word count and content depth analysis
Schema & Structured Data
Unlock rich results in Google Search — stars, FAQs, breadcrumbs, product info, and more. We validate your JSON-LD against Google's official requirements.
- JSON-LD block detection with @context and @type validation
- Required and recommended property checks per schema type
- Rich results eligibility assessment (Article, Product, FAQ, Organization, etc.)
- Nested entity validation and URL/date format checks
Links Health
Broken links hurt user experience and waste crawl budget. We check every link on your page — internal and external — for issues that affect SEO.
- Broken internal and external link detection (404, timeouts)
- Redirect chain analysis for internal links
- Empty href and javascript:void(0) link detection
- Generic anchor text warnings ("click here", "read more")
- External link rel attribute checks (noopener, nofollow)
Image Optimization
Images are often the heaviest assets on a page. Proper optimization improves load speed, accessibility, and search visibility.
- Alt text coverage for every meaningful image
- Explicit width/height attributes to prevent layout shift (CLS)
- Modern format detection (WebP, AVIF vs legacy JPG/PNG)
- Lazy loading for below-the-fold images
Open Graph & Social Sharing
Control how your pages look when shared on Facebook, Twitter, LinkedIn, and messaging apps. A compelling social preview drives more clicks.
- Open Graph title, description, and image validation
- Twitter Card type and tag completeness
- Social preview rendering with actual tag values
