SEO Design Patterns
Page Structure
- One H1 per page (the primary topic).
- Logical heading hierarchy (H1 → H2 → H3).
- Descriptive URLs: /products/running-shoes not /p/12345.
- Breadcrumbs with structured data markup.
Meta Tags
- Title: 50-60 characters. Primary keyword + brand.
- Description: 120-155 characters. Compelling summary with CTA.
- Open Graph: og:title, og:description, og:image for social sharing.
- Image alt text: Descriptive, natural language.
Performance (SEO Impact)
- Core Web Vitals: LCP < 2.5s, FID < 100ms, CLS < 0.1.
- Mobile-first indexing: mobile experience is what Google sees.
- Fast loading: compress images, lazy load below-fold.
Content
- Answer questions directly (featured snippet opportunity).
- Internal linking between related pages.
- Updated content ranks better (show "last updated" dates).
- Structured data (FAQ, HowTo, Product, Review schemas).
