Technical SEO: The technical half of being found.
The technical half of being found – fast pages, correct markup, multilingual content that stays in step, and a content model the client can actually run.
Three published case studies

What that includesDISCOVERY
Technical SEO, multilingual
- Technical SEO – sitemaps, robots, structured data, redirects
- Core Web Vitals and page speed work
- Multilingual sites kept in step from one source
- Content models an editor can use without training
- Transactional email and deliverability
Every machine-readable surface is generated from it, never maintained by hand.
- Sitemapsitemap.xml
- Robots policyrobots.txt
- Structured dataJSON-LD
- Share imagesone per page
- Plain-text summary for language modelsllms.txt
Most of what holds a small site back is technical rather than editorial: pages that render late, a sitemap nobody generates, a translation that covers half the site, or a content model so awkward that nothing gets published.
We fix that end of it. Pages are rendered statically where they can be, scripts are kept off the critical path, and the machine-readable surfaces – sitemap, robots policy, structured data, social previews and, increasingly, a plain-text summary for language models – are generated from the content rather than maintained by hand.
Where a site is bilingual, both languages come from the same source, so publishing once publishes everywhere.
01Who it is for
A business whose site is slow, half-translated or hard to update, or which does not show up for the searches its customers actually make, and which wants the technical causes fixed before anyone writes more copy.
If this is the wrong service for you, we will say so and point you to the right one.
02What you get
- Pages rendered ahead of time, with scripts kept off the critical path
- A sitemap, robots policy and structured data generated from the content, never maintained by hand
- A share image per page, rendered at build time
- A plain-text summary of the site for the language models that now read it
- Both languages from one source, if the site is bilingual, and a content model an editor can use without training
This site is built the same way: every page is static, the sitemap dates each page by its last real change, and each service and product carries its own structured data and share image.
03What we need from you
Access to the site and its hosting, to the domain's DNS, and to its search console if it has one; and the searches you would like to be found for, in your customers' words rather than ours.
Is this what you need?
Describe the job in a few lines. If this service is the wrong fit, we will say so and point you to the right one.

Proof
Where we have done it
Three case studies, written from the source code and anonymised.
-

A content-managed site for an independent practice
A professional services firm
Moved a practice off a hosted site builder onto a Next.js site with its own editing studio, so services, programmes and events publish without a deploy.

A bilingual clinic site the clinic can edit safely
A Cyprus health clinic
A WordPress block theme for a private clinic, with a booking form, English and Greek from one source, and a deploy that rebuilds the CSS for you.
In use · edited by the clinicRead the case -

A storefront where each work is one of one
An independent art studio
An artwork storefront on Next.js and PostgreSQL – originals that sell once, prints that do not, and commissions handled in the same system.

How we work
How an engagement runs
Four steps, and we stay after the fourth: what we build, we host and support.
- 01
Discovery
We map how the business actually runs today, including the spreadsheets and the workarounds.
- 02
Build
We build the system in small, shippable pieces you can use before it is finished.
- 03
Integrate
We connect it to the couriers, payment providers and marketplaces you already depend on.
- 04
Host and support
We run it on infrastructure you own or on ours, as agreed, with backups, monitoring and someone to call.

inquiries@kdvassiliougroup.com01Will we be able to edit it ourselves?
Where editing is part of the job, yes. We build content models an editor can use without training; one clinic edits its own pages in two languages from a single source.
