Technical SEO and Website Speed Optimization
I help websites become easier for search engines, AI assistants and real users to understand by improving technical SEO, structured data, page speed and crawl signals.

This service is for websites with weak metadata, missing schema, poor Core Web Vitals, crawl issues, duplicate pages or slow JavaScript-heavy frontends.

Structured data
Add schema for services, person, organization, FAQ, breadcrumbs and case-study content where relevant.
Speed optimization
Optimize images, scripts, fonts, rendering and layout stability for better Core Web Vitals.
AI-search readiness
Create direct service answers, FAQ structure, llms.txt and consistent entity signals.

FAQ
Quick answers before we start.
What technical SEO issues can a developer fix directly?
A developer can fix crawlable HTML, metadata, schema, canonical URLs, sitemap output, robots rules, redirects, image delivery, JavaScript weight and Core Web Vitals issues.
Can you improve Core Web Vitals?
Yes. I can optimize images, fonts, scripts, layout stability and rendering behavior to improve LCP, CLS and INP where the codebase allows it.
Can you prepare a site for AI search?
Yes. I can add answer-first content blocks, FAQ schema, Person and Service schema, clean internal links and an llms.txt file for AI discovery.

Technical SEO is strongest when it is implemented in the codebase, not only described in an audit. Developers can fix crawl signals, rendering, structured data and performance at the source.
Hiring comparison
Freelance Developer vs Web Agency
A senior freelance developer is often faster and more direct for scoped technical builds. An agency can be useful when the project needs a large team, brand strategy, content production and ongoing account management.
