WordPress Developer in Metz–Thionville
Seganiko is your WordPress developer in Metz and Thionville. We create, redesign, secure and maintain WordPress sites for SMEs across Moselle, with a single, French-speaking point of contact. Our agency is based in Algrange, between the two towns, and at every stage you remain the owner of your site and its code.
Our WordPress development covers creation, redesign and maintenance, adapting to your business and your budget.
What does a WordPress developer actually do for your business?
A WordPress developer designs, fixes and evolves your site: creation, redesign, bug fixing, speed optimisation, security and custom features. In short, this is the person who makes your site fast, reliable and easy to update, without you having to touch the code.
WordPress runs more than 40% of all websites worldwide, according to W3Techs. It is not a niche tool but a standard foundation that a developer can work on years later, without locking you into proprietary technology.
For an SME, this translates into concrete tasks: speeding up a site that has become slow, securing a vulnerable installation or adding a feature that standard plugins do not cover.
Which WordPress services do we offer in Metz–Thionville?
We cover the full life cycle of a WordPress site, from creation through to maintenance. The table below summarises our four main services, what they include and who they are for.
| Service | What is included | Who it is for |
|---|---|---|
| Creation and redesign | Mock-up, WordPress integration, content, go-live | Business with no site or an ageing one |
| Maintenance and security | Updates, backups, monitoring, security patches | Live site that must stay online |
| Performance (Core Web Vitals) | Speed optimisation, caching, images, LCP/INP/CLS | Slow site that is losing visitors |
| Custom plugins and features | Bespoke development, integrations, APIs, forms | Business need beyond the scope of standard plugins |
On performance, the goal is measurable: according to web.dev, a good score aims for an LCP under 2.5 seconds, an INP under 200 milliseconds and a CLS under 0.1. On the BGL Fashion WooCommerce store, we brought the LCP down from 4.2 to 1.9 seconds, and the client saw a 12% increase in conversions (client testimonial). See also our method for optimising WordPress speed and Core Web Vitals.
We work on classic WordPress as well as headless setups, and we develop custom plugins following the standards of the official WordPress documentation.
How do you keep control (and ownership) of your WordPress site?
You keep control of your site by holding the access credentials and ownership yourself. No essential element should depend on a single provider. Here is what you should always own in your own name.
- The domain name, registered in your name
- The hosting account, in your name
- The WordPress administrator access
- The FTP/SFTP and database access
- A recent, exportable backup of the site
- The source code and documentation for custom development
Our principle is simple: on delivery, you hold all of these access credentials and you remain the owner of your site. Ownership of custom code and the terms of transfer are set out in the contract: thanks to our Git + staging workflow, you own the code, and the entire repository is handed over to you on delivery.
Is your WordPress site GDPR-compliant?
A WordPress site is not GDPR-compliant by default. At a minimum it must obtain consent before placing non-essential cookies, display a legal notice and a privacy policy, and secure the data collected through forms. For a site based in Metz or Thionville, the relevant authority is the CNIL, not Luxembourg’s CNPD.
The CNIL sets precise rules for the use of cookies and other trackers: consent must be freely given, informed and as easy to refuse as to accept. We put these foundations in place, and you can then check your site with our 12-point WordPress GDPR self-audit or go deeper with our GDPR compliance guide for WordPress.
How much does a WordPress developer in Metz–Thionville cost?
The cost depends on the mode of collaboration: a fixed-price project for a creation or redesign, a daily rate for one-off work, or a monthly plan for maintenance. The price varies according to the number of pages, the custom features and the level of support expected.
| Service | Pricing model | Indicative range |
|---|---|---|
| Site creation or redesign | Fixed-price project | 2 500 € – 5 000 € excl. VAT (beyond this, on request) |
| One-off work (bug, enhancement) | Daily rate | on request |
| Maintenance and security | Monthly plan | 150 € – 350 € excl. VAT/month |
The maintenance plan brings together updates, backups and security monitoring, with a defined response time: from 48 h on the 150 € excl. VAT/month plan, to 24 h on the 350 € excl. VAT/month plan, and down to 4 h with a custom SLA.
When do you need a WordPress developer, and when not?
You do not always need a developer. For a very simple showcase site, a one-off need and a tight budget, an online editor or a turnkey theme may be enough. If your priority is to create a first local site, see our website creation service in Thionville and Metz.
A developer becomes worthwhile as soon as you have custom features, performance targets to meet or a site that genuinely generates revenue. Conversely, WordPress is not always the right choice: a highly specific business application or a real-time platform calls for dedicated development. We tell you this frankly rather than forcing the tool.
