Technical SEO & Performance Optimization Services

Website performance is not just about user experience — it directly impacts your Google rankings. Core Web Vitals are a confirmed ranking factor, and sites that load faster consistently outperform slower competitors in search results. I combine deep technical expertise with data-driven SEO strategies to deliver measurable improvements.

My own portfolio site (the one you are on right now) scores 90+ on both mobile and desktop PageSpeed, with zero render-blocking resources, critical CSS inlined, all scripts deferred, and comprehensive structured data. I apply the same rigorous optimization standards to every client project.

What I Optimize

  • Core Web Vitals: LCP, INP, and CLS optimization to meet Google's "Good" thresholds
  • Render-blocking resource elimination through critical CSS inlining and script deferral
  • Image optimization: format selection (WebP/AVIF), lazy loading, proper sizing
  • Font optimization: self-hosted WOFF2, font-display swap, preloading
  • Server-side optimization: Brotli/Gzip compression, caching headers, CDN configuration
  • Structured data implementation: FAQ, Reviews, Breadcrumbs, Organization, Product schemas
  • Title tags, meta descriptions, heading hierarchy, and internal linking
  • Sitemap and robots.txt configuration, canonical tags, hreflang setup

Why Hire a Developer for SEO

Most SEO agencies focus on content and link building but struggle with technical implementation. As a developer who specializes in SEO, I can directly implement changes to your code, server configuration, and structured data — not just recommend them. This means faster execution, proper implementation, and no lost-in-translation issues between an SEO consultant and a developer.

1

Technical SEO Audit

Comprehensive crawl of your site to identify technical issues: broken links, crawl errors, duplicate content, missing meta tags, slow pages, and indexation problems.

2

Performance Baseline

Measure current Core Web Vitals (LCP, INP, CLS), PageSpeed scores, and load times. Establish benchmarks for tracking improvement.

3

Priority Fixes

Address critical issues first: render-blocking resources, unoptimized images, missing caching headers, and broken structured data.

4

On-Page Optimization

Optimize title tags, meta descriptions, heading structure, internal linking, and content for target keywords. Implement structured data schemas.

5

Advanced Optimization

Critical CSS inlining, font optimization, lazy loading, resource hints (preconnect, preload), compression (Brotli/Gzip), and CDN configuration.

SEO & Performance FAQ

Technical SEO fixes (PageSpeed, Core Web Vitals, structured data) can show improvements within 1-4 weeks as Google recrawls your pages. Ranking improvements for competitive keywords typically take 2-6 months depending on your domain authority, competition level, and content quality. I focus on quick wins first — fixing technical issues that provide immediate performance gains — while building toward long-term ranking improvements.

Google considers a PageSpeed score of 90+ as "Good" for both mobile and desktop. However, the real metrics that matter are Core Web Vitals: LCP under 2.5 seconds, INP under 200ms, and CLS under 0.1. These are the actual ranking signals Google uses. I optimize for these real-world metrics, not just the score number, though improved metrics naturally result in higher scores.

Structured data is JSON-LD code that helps Google understand your page content. When implemented correctly, it enables rich results in search — FAQ dropdowns, review stars, breadcrumbs, product info, and more. Rich results dramatically increase click-through rates, with some studies showing 20-35% CTR improvements. I implement all relevant schema types and validate them using Google's Rich Results Test.

Yes, Google Search Console is central to my SEO workflow. I use it to monitor indexation status, identify crawl errors, track keyword rankings, analyze click-through rates, submit sitemaps, and request re-indexing after fixes. I can work with your existing GSC setup or help you configure it from scratch. All my recommendations are data-driven based on actual search performance data.

Technical SEO covers the infrastructure: page speed, mobile responsiveness, structured data, crawlability, indexation, canonical tags, and server configuration. Content SEO covers the words on the page: keyword targeting, title tags, meta descriptions, heading structure, and content quality. Both are essential. I specialize in technical SEO with strong on-page optimization capabilities. For content strategy and copywriting, I can provide keyword recommendations and content briefs.

Absolutely. Core Web Vitals optimization is one of my primary specialties. I fix LCP issues by optimizing images, eliminating render-blocking resources, and implementing critical CSS inlining. INP improvements come from code splitting, reducing JavaScript execution time, and optimizing event handlers. CLS fixes involve proper image dimensions, font loading strategies, and layout stability improvements. I have achieved "Good" scores across all three metrics on multiple client sites.
