Technical SEO — built by developers, not marketers
The speed, indexability and structure Google ranks on are developer work. We build that foundation — and prove it on our own site.
Technical SEO is the part of search optimisation about how your site is built, not its copy: load speed (Core Web Vitals), indexability, structured data, redirects, hreflang and how Google renders your JavaScript. It's developer work — exactly where most marketing agencies fall short. For businesses that want to rank higher technically without touching their content.
Why a developer, not a marketer?
Core Web Vitals, indexation policy, structured data, redirect mappings, hreflang and JavaScript rendering are code topics. A marketing agency advises and hands you a report; a development agency fixes the cause. Because we build your site ourselves, we solve the problem where it lives — in the code.
What technical SEO means with us
Core Web Vitals & pagespeed
Green LCP, CLS and INP on a static-fast foundation. Speed is a direct ranking factor and lifts conversion — slow sites lose visitors before they even load.
Indexation & crawl control
We make sure Google indexes exactly the right pages: robots, sitemap, canonicals and clearing out thin or duplicate URLs that dilute your authority.
Structured data (schema)
Service, FAQ and Organization schema so you stand out with rich results, and get cited by AI search engines.
Redirects & migrations
301 mappings that preserve ranking signals during a restructure or migration — no traffic leaking to dead URLs (a mistake we fixed for ourselves just this week).
Hreflang & international
Correct language and region targeting so your multilingual site doesn't compete with itself and each language lands with the right searcher.
AI findability (AEO/GEO)
Optimised to be cited by ChatGPT, Perplexity and Google's AI overviews — the fastest-growing search traffic right now.

We don't just apply technical SEO for clients — we built a dedicated platform for it at seo.jongma.dev. The proof is measurable, not a sales pitch.
What does it cost?
A technical SEO audit with concrete fixes is a defined project; ongoing optimisation runs monthly. The Quote Tool gives you a tailored estimate in under a minute.
Frequently asked questions
Regular (content) SEO is about text, keywords and authority. Technical SEO is about the build: speed, indexability, structure and code. Without a sound technical foundation, even perfect content won't reach the top.
Both in one. We write the code and steer on findability. For technical SEO — Core Web Vitals, pagespeed, indexation, schema — that's an advantage: we fix the cause instead of advising on it.
Yes. Speed is our specialty: we build on a static-fast foundation and optimise LCP, CLS and INP to green. We raise the score on existing sites too.
