Comprehensive search engine optimization covering technical SEO, content optimization, and strategic planning.

Technical SEO Audit

Site Crawlability Checklist

• robots.txt properly configured (not blocking important pages)
• XML sitemap exists, is valid, and submitted to Search Console
• No orphan pages (every page reachable via internal links)
• Canonical tags set correctly (no duplicate content issues)
• Hreflang tags for multi-language sites
• Clean URL structure (no parameters, descriptive slugs)
• Proper 301 redirects for moved/deleted pages
• No redirect chains or loops

Page Speed & Core Web Vitals

• LCP (Largest Contentful Paint): Target < 2.5s
• INP (Interaction to Next Paint): Target < 200ms
• CLS (Cumulative Layout Shift): Target < 0.1

Common fixes:

• Optimize and lazy-load images (WebP/AVIF format, srcset for responsive)
• Minimize render-blocking CSS/JS
• Use font-display: swap for web fonts
• Preload critical resources
• Implement proper image dimensions to prevent CLS

Mobile-First Optimization

• Responsive design (no horizontal scrolling)
• Touch-friendly tap targets (48px minimum)
• Readable font sizes without zooming (16px minimum body)
• No intrusive interstitials

Content Optimization

On-Page SEO Elements

<!-- Title Tag: 50-60 characters, primary keyword near front -->
<title>Primary Keyword - Supporting Context | Brand</title>

<!-- Meta Description: 150-160 characters, compelling CTA -->
<meta name="description" content="Clear value proposition with primary keyword. Include a call-to-action that encourages clicks.">

<!-- Heading Hierarchy -->
<h1>One per page, contains primary keyword</h1>
<h2>Section headers with secondary keywords</h2>
<h3>Subsection headers with related terms</h3>

Content Structure

• Introduction: Hook + primary keyword in first 100 words
• Body: Comprehensive coverage of topic with semantic keywords
• Headings: Clear hierarchy (H1 > H2 > H3), keyword-rich but natural
• Internal links: Link to related pages with descriptive anchor text
• Media: Images with descriptive alt text, relevant videos
• Conclusion: Summary + clear next action

Keyword Strategy

1. Primary keyword: Main topic (1 per page)
2. Secondary keywords: Related topics (2-5 per page)
3. Long-tail variants: Specific queries users actually search
4. Semantic keywords: Related terms and synonyms (LSI)

Content Quality Signals

• Comprehensive coverage (2000+ words for competitive topics)
• Original research, data, or insights
• Updated regularly (include "Last updated" dates)
• Expert authorship (author bio, credentials, E-E-A-T signals)
• User engagement (low bounce rate, high time on page)

Schema Markup (Structured Data)

Common Schema Types

// Article Schema
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Article Title",
  "author": {"@type": "Person", "name": "Author Name"},
  "datePublished": "2026-01-01",
  "dateModified": "2026-04-14",
  "image": "https://example.com/image.jpg",
  "description": "Article description"
}

// FAQ Schema
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [{
    "@type": "Question",
    "name": "Question text?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text": "Answer text."
    }
  }]
}

// Product Schema
{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "Product Name",
  "offers": {
    "@type": "Offer",
    "price": "99.99",
    "priceCurrency": "USD",
    "availability": "https://schema.org/InStock"
  }
}

// LocalBusiness Schema

Site Architecture

URL Structure

example.com/
├── /category/                    # Category page
│   ├── /category/subcategory/    # Subcategory
│   │   └── /category/subcategory/page-slug/  # Content page
├── /blog/                        # Blog index
│   └── /blog/post-slug/          # Blog post
└── /tools/                       # Tool/resource pages

Internal Linking Strategy

• Hub-and-spoke: Pillar pages link to cluster content and vice versa
• Contextual links: Link within body content (not just navigation)
• Breadcrumbs: Help users and search engines understand hierarchy
• Related content: Suggest relevant pages at end of content
• Anchor text: Descriptive, keyword-rich (avoid "click here")
