Performance & SEO Optimization
Speed Wins. Literally.
Google uses page experience as a ranking signal. Slow sites lose visitors, conversions, and rankings. I fix that.
What I Optimize
Core Web Vitals
| Metric | Target | What I Do |
|---|---|---|
| LCP (Largest Contentful Paint) | < 2.5s | Image optimization, preload, CDN |
| FID (First Input Delay) | < 100ms | Code splitting, defer non-critical JS |
| CLS (Cumulative Layout Shift) | < 0.1 | Size attributes, font optimization |
Technical SEO
- Meta tags — Title, description, OpenGraph, Twitter Cards
- Structured Data — JSON-LD schemas for rich results
- Canonical URLs — Prevent duplicate content penalties
- Sitemaps — XML sitemaps with image and video entries
- robots.txt — Proper crawl directives
- Internal linking — Silo structure for topical authority
- Breadcrumbs — For both users and search engines
AI & LLM Search Optimization
Traditional SEO isn't enough anymore. I optimize for:
- LLM-friendly structured data — Schema.org markup that AI crawlers parse
- Clear information hierarchy — Well-structured content that AI can extract
- Entity optimization — Proper semantic markup so LLMs understand who you are
- Content freshness signals —
