Websites that Google and AI understand, from day one.
A Belgian digital studio in Brussels and Liège, Nelty builds search engine optimization (SEO) and visibility in AI answers (GEO) into every Next.js website and every Medusa store, from the start. It's not an add-on or a line on the quote: it's how we build.

Why it's included
Search rankings are decided in the code.
A slow site, poorly structured or unreadable to a crawler, can't be rescued with keywords added after the fact. Page structure, speed, structured data: it's all decided when the site is designed and built. We only offer SEO and GEO on sites we build. We control every line, so we can stand behind what we promise.
Why not…
- An SEO agency on your current siteIt recommends, someone else has to fix. The deep work often stays on hold.
- An SEO pluginIt helps fill in tags, not fix the structure or the speed.
- Dealing with it laterSEO added after the fact often means rebuilding part of the site.
What's included
Five foundations, in every project.
Everything that happens on your site is included. What happens elsewhere (links from other sites, press coverage) is handled separately, on quote.
An architecture built for search
One page per search intent, titles and descriptions written page by page. In a redesign, every old address is redirected to the new one.
A fast site
Lightweight pages, measured against Google's Core Web Vitals.
Structured data
Your business, services and products described in a format search engines read, with price, availability and reviews for online stores.
Pages AI can cite
Direct answers, an FAQ written from your customers' real questions, a site open to the crawlers of ChatGPT, Perplexity, Gemini and Claude, with an llms.txt file.
A consistent identity
Your Google Business Profile created or updated, Search Console set up, and the same description of your business everywhere.
How to improve your local SEO?Already have a website?
The answer is often a redesign.
We don't do SEO on a site we didn't build. If yours is holding you back, we carry over your content, redirect every address and keep what already works.
Talk about a redesignFrequently asked questions
What we're asked most often.
Are SEO and GEO billed separately?
No. Everything that happens on your site is part of every website and store we deliver, with no separate line on the quote. What happens elsewhere (links from other sites, press coverage) is handled separately, on quote.
Is Nelty an SEO agency?
Yes, for the websites we build. Search rankings depend on a site's structure and speed, which we only control on those. If your current site is holding you back, we can talk about a redesign.
What is GEO?
GEO, short for Generative Engine Optimization, means making a site understandable and citable by assistants such as ChatGPT, Perplexity, Gemini or Claude. In practice: clear answers, structured information and a consistent identity across the web. What is GEO? The full article
Do you guarantee the top spot on Google or a mention in ChatGPT?
No, and nobody can. What we guarantee are the foundations: a fast, well-structured site that search engines and AI can read.
How long does it take to see results?
A new site is indexed within a few days to a few weeks. Rankings then build up over several months, depending on the competition in your industry and how regularly you publish.
What happens after launch?
The site is delivered ready to rank. Publishing regularly remains the best lever, and your admin interface lets you do it yourself.
Do you also run advertising?
Yes, we run Google Ads and Meta Ads campaigns for the sites we build. Google Ads and Meta Ads
