Technical SEO & Performance

The Engineering Side of Ranking on Google

Most SEO agencies can write blog posts and build links, but freeze the moment the problem is technical — a site that loads slowly, renders wrong for Google, or buries its content behind JavaScript. That technical layer is exactly where rankings are won or lost, and it's exactly what a development studio is built to fix.

At Codified Studio, we handle the engineering side of SEO — Core Web Vitals, site structure, schema, and rendering — the work that makes everything else your marketing does actually count. Built by the same in-house team that builds the sites.

Technical SEO — The Foundation Everything Else Sits On

SEO has three parts: content (what you say), off-page (links and authority), and technical (whether Google can crawl, render, and rank your site at all). You can write the best content in your market, but if your pages load slowly, render blank without JavaScript, or lack the structure Google expects, it won't matter. Technical SEO is the foundation — and it's the part marketing agencies most often can't touch, because it's an engineering job, not a copywriting one.

What We Fix

Core Web Vitals & speed.

The load-speed and stability metrics Google uses as a ranking factor — measured, diagnosed, and fixed at the code level, not papered over with a caching plugin.

Crawlability & rendering.

Making sure Google sees your full content — fixing JavaScript rendering, indexation, sitemaps, and the structure that lets search engines actually read your site.

Schema & structured data.

Marking up your pages so Google understands them — and rewards you with rich results: FAQs, reviews, breadcrumbs, and more real estate on the results page.

Local SEO foundations.

Google Business setup, local schema, and the on-page signals that get you found by customers searching in your area — the bedrock of local visibility.

What's Included in an SEO Engagement

A typical SEO & performance engagement covers:

A full technical SEO audit with a prioritised, plain-English fix list
Core Web Vitals and PageSpeed fixes at the code level
Crawlability, indexation, sitemap, and rendering fixes
Schema markup and structured data for rich results
Site structure, internal linking, and on-page optimisation
Local SEO and Google Business setup where relevant

Rankings and speed are baked into how we build — every Next.js and WordPress site ships SEO-ready, so this is as much prevention as cure.

Ranking Is Engineering — Not Just Content

The reason we can do the SEO work marketing agencies outsource is simple: it's code. Fixing render-blocking scripts, restructuring how a page is built, adding schema, tuning the database query behind a slow page — that's development work, and it's what we do all day.

Core Web Vitals fixed in the code, not masked by a plugin that stops working
Server-side rendering and clean markup so Google sees complete pages
Structured data implemented properly, validated against Google's requirements
Monthly reporting so you can see rankings and Core Web Vitals actually move

“Our SEO agency said the developers need to fix it” is a sentence we hear constantly. We're the developers — which is why we can act on the audit instead of just handing you one. Read why a slow site quietly loses customers.

Ideal For

Sites failing Core Web Vitals
Businesses whose SEO agency is blocked on 'dev work'
Stores and sites that rank below their content quality
Local businesses needing to be found in their area

How We Deliver — From First Call to Launch (and After)

No black box. Here's exactly what happens once you bring us in:

01

Discovery & scoping

A real conversation about the problem, the users, and the constraints — not a sales call. We leave it knowing exactly what needs building and why.

02

Fixed proposal & quote

You get a plain-English scope document, a timeline, and a fixed price. What's included, what's excluded, and what happens if scope changes — all in writing before any money moves.

03

Design & architecture

Wireframes, UI, and the technical architecture — database schema, API design, hosting — agreed up front so there are no expensive surprises mid-build.

04

Build in sprints

Development happens in short, reviewable cycles with a shared board. You see working software early and often, not a single black-box handoff at the end.

05

QA & testing

Every feature is tested — automated tests plus manual QA on real devices — before it's marked done. Nothing ships on a “works on my machine”.

06

Launch & handoff

Deployment, performance checks, and a walkthrough. You get the source code, the hosting, and the documentation — full ownership, zero lock-in.

07

Support & iteration

We stay on for bug fixes, monitoring, and new features on a retainer or ad-hoc basis — whichever fits how your product will actually grow.

How Much Does SEO & Performance Cost?

SEO and performance cost in the UK varies by scope and whether it's a fix or ongoing. For reference:

OptionTypical range
UK SEO agency — retainer£800 – £3,000 / month
Technical SEO audit (one-off)£1,000 – £5,000
Freelance (variable quality)£300 – £1,500
SEO & performance via Codified Studiofrom $700

The cheapest quote on paper isn't always the cheapest in practice — a low day rate that needs heavy management, or a build that needs redoing, costs more than a fixed scope delivered right the first time. With Codified Studio, pricing is transparent from the first quote: no hidden onboarding fees, no surprise scope creep, and full code ownership at the end.

FAQ

Frequently Asked Questions

Most SEO agencies focus on content and links, and outsource anything technical to “the developers”. We are the developers — so we handle the technical side directly: Core Web Vitals, rendering, schema, and site structure. We're the ones the audit usually tells you to hire, which means we can fix problems instead of just documenting them.

Our focus is the technical and performance side — the engineering that content and links sit on top of. We'll optimise on-page structure and can advise on content strategy, but if you want heavy content production or link outreach, we're best paired with a content-focused partner while we own the technical foundation.

Yes — it's core work. We measure and diagnose what's actually causing the failures (render-blocking scripts, layout shift, slow server responses, heavy images) and fix them in the code. Most sites we take on move from failing to passing within the first engagement.

Projects are priced in USD and invoiced via Payoneer or Elevate Pay — no international wire fees, no currency surprises. Fixed-price projects run 50% deposit to start, 50% on delivery, against a plain-English scope document agreed before any money changes hands.
