SEO agency website
Showcase for a freelance SEO expert dedicated to improving online visibility and driving organic traffic for businesses.
The freelancer offers a comprehensive range of SEO services, including technical optimization, content refinement, and strategic link-building. SEO audits are emphasized as critical for enhancing website performance and boosting sales. The freelancer also specializes in local SEO to help businesses connect with customers in their vicinity.
Technologies Used
The site was built on a modern static stack that actually supports ranking — because the thing the client sells (SEO) must also be visible in their own website:
Astro
Generates static HTML with minimal JavaScript — translates to 95–100 scores in PageSpeed Insights.
Vue 3
Interactive components (accordions, filters) hydrated only where they're actually needed — the "islands architecture" pattern.
TypeScript
Static typing across the application layer — reduces whole classes of runtime errors.
UnoCSS
On-demand CSS engine (Tailwind-compatible) that emits only the classes actually used.
Markdown + MDX
File-based blog — no database; content versioned in git next to the code.
PWA
Manifest and service worker; installable on mobile devices.
Scope of work
- Design and implementation of a business-card site with blog and project portfolio.
- Structured data configuration (
Organization,Service,BreadcrumbList,FAQPage) for rich snippets in Google. - Proper hreflang and canonical setup for a future multilingual version.
- Image optimization (WebP/AVIF, lazy loading,
aspectRatioto eliminate CLS). - Contact form integration and GA4 analytics.
- Continuous deployment — every merge to
mainautomatically publishes a new version.
Outcomes
- Core Web Vitals in green (LCP < 1.5 s, CLS < 0.01) on mobile.
- Full page load under 1 second on a typical 4G connection.
- Zero hosting costs on the client side (static site served from a CDN).
- Easy content growth — the client adds blog posts in Markdown through a Git-based panel.
