What a good website should do

Your website should bring you customers

A polished design is worthless if Google can't find you, the mobile version drags, or visitors don't know how to reach you. I build websites that show up in search, load fast and push visitors to act.

Visible on Google

Technical SEO included from day one: meta tags, structure, schema, sitemap. Your customers find you when they search for you.

Fast on mobile

Core Web Vitals optimized, images served in the right format, lean code. Over 60% of traffic comes from mobile, it has to be flawless.

Built to convert

Clear calls to action, focused user journey, short forms. Every page guides the visitor toward something concrete: call, book, buy.

SEO included in every engagement

SEO included on every project

Indexing, Core Web Vitals, schema.org and page structure are handled from the start, not bolted on at the end.

Technical SEO

Core Web Vitals, schema.org, sitemap, hreflang, Search Console indexing.

  • Lighthouse 95+ on mobile
  • Schema.org Person, Service, Product
  • Validated sitemap and hreflang
  • Search Console indexing

Content SEO

Keywords, Hn tagging, E-E-A-T signals, internal linking.

  • Targeted keyword research
  • Optimized Hn structure and tags
  • E-E-A-T signals
  • Internal linking

Local SEO

Google Business Profile, LocalBusiness schema, NAP citations, location pages.

  • Optimized Google Business Profile
  • LocalBusiness schema
  • Consistent NAP citations
  • City pages

This site as an example
