Development
Professional website development
A professional website presents your company, your offers and your content to prospects, customers and candidates. It must load quickly, be found on Google, display correctly on mobile and be editable by your teams without technical help.
Agencei builds brochure sites, corporate sites, multilingual sites and content-heavy sites for SMEs, groups, non-profits and institutions. The technology depends on your needs: Next.js with a headless CMS when performance and customization come first, WordPress when editorial autonomy and the plugin ecosystem are decisive.
Every site is delivered with a structure designed for organic search, Core Web Vitals monitoring, suitable hosting and documentation for your contributors.
When do we step in?
Building the site of a company at launch
You need a credible online presence quickly: offer pages, contact form, blog and legal pages, on a foundation that can grow.
Replacing a slow or outdated site
Your current site loads slowly, is no longer updated and is losing positions on Google. We rebuild it while keeping your URLs and your existing rankings.
Managing large content volumes and several languages
Training catalogue, branch network, news in several languages: a structured CMS and suitable templates prevent the number of pages to maintain from exploding.
Handling traffic spikes
Advertising campaigns, media coverage or events: a statically rendered site served by a CDN absorbs spikes without extra infrastructure cost.
Integrating the site with your tools
CRM connection, appointment booking, candidate area, maps or a catalogue synchronized with your ERP.

Frequently asked questions
Next.js or WordPress for my website?
WordPress fits when your teams publish frequently and need to manage the site independently with proven plugins. Next.js with a headless CMS is preferable for a very fast, highly customized site or one exposed to large traffic spikes. We advise you after reviewing your usage.
How long does it take to build a website?
A brochure site with a handful of pages is usually delivered in a few weeks. A multilingual site with many templates and integrations often takes several months, including content writing and validation.
Can you migrate the content of my current site?
Yes. We export your pages, articles and media, clean them up and reintegrate them into the new structure, with a redirect plan to preserve your rankings.
Will the site rank well on Google?
We deliver a sound technical foundation: markup, speed, structured data, sitemap, mobile. Rankings then depend on the quality and regularity of your content, which we can help with.
Who hosts and maintains the site?
We recommend hosting suited to the chosen technology and can manage it for you. Maintenance (updates, backups, monitoring) can be covered by a separate contract.
