Technical SEO

Semantic HTML, structured data, Core Web Vitals optimisation, and crawlability audits for JavaScript applications.

Technical SEO is the foundation of organic search visibility — especially for JavaScript-heavy applications. I help businesses ensure their React, Next.js, and SvelteKit applications are fully crawlable, indexable, and optimised for search engines.

My technical SEO service begins with a comprehensive crawl audit. Using tools like Screaming Frog, Sitebulb, and Google Search Console, I identify indexing issues, crawl budget waste, duplicate content, and missing structured data. For JavaScript applications, I verify that Google can render and index client-side content — implementing SSR or SSG where client-side rendering falls short.

Structured data is a key differentiator. I implement comprehensive schema.org markup — Person, Organization, WebSite, BreadcrumbList, Article, Product, FAQ, and more — enabling rich snippets in search results. On this portfolio site, I have deployed 14+ schema types that provide Google with a complete understanding of the content.

Performance and SEO are inseparable. I optimize Core Web Vitals — LCP, INP, and CLS — because Google's page experience ranking signal directly impacts search positions. I implement semantic HTML with proper heading hierarchies, landmark regions, and descriptive link text. I also handle the technical plumbing: XML sitemaps, robots.txt configuration, canonical URLs, hreflang tags for multilingual sites, and structured URL patterns.
