Our Technical SEO Service Process
We audit your site’s structure and speed using Screaming Frog, Sitebulb, GSC, and server logs. This reveals crawl waste, index gaps, Core Web Vitals issues — not just surface scans.
We resolve blocked pages, broken links, crawl errors, and ensure everything important is discoverable and indexable.
We improve load speed, mobile responsiveness, and clean up code to align with Core Web Vitals.
We refine URL structure, implement schema, and build a internal linking system.
We tighten security (HTTPS, canonical tags, redirects), manage sitemaps, and build a technical foundation that scales with growth.
