Agentic website
Every change to your website is manual work today, so it happens too late or never. With AI website development, AI agents build and maintain your site across all pages and languages at once: an agentic website. Your team decides and approves, and nothing goes live without sign-off.

Sound familiar?
Every change to our site is a ticket, and then we wait for weeks.
Our site is held together by plugins and keeps getting slower and more fragile.
We want to grow in more countries, but a new language takes months.
ChatGPT and Perplexity mention our competitors, not us.
How we help
An agentic website turns this around: you ask for a change in plain language, agents carry it out on every relevant page and in every language, and a person approves it on a preview link before anything goes live. Weeks of work become days.
Why Customer Impact
From idea to live in days instead of weeks. Your marketing moves at the pace of the market, not the pace of a ticket queue.
New languages and markets without an extra team. customerimpact.be runs in four languages, each with its own pages on the same rhythm.
Built to be found in Google and mentioned in AI answers: clean HTML, structured data and AI crawlers welcome.
No stack of plugins and no platform that locks you in. The code and the content are yours, even if you stop later.
About Customer Impact
Customer Impact is a digital marketing agency founded by Tanguy De Keyzer. For more than 10 years we have been building the growth engine of startups, scale-ups and established companies.
We have been working with AI in marketing for three years and building agentic websites for two. Tanguy De Keyzer leads strategy and SEO, Sam van den Bos builds the websites and the systems behind them as CTO, and Fern, Robrecht and Pieter Jan take care of SEO, content and execution. Our own site runs the same way.
What we stand for:
What we do
Agents write the code, migrate the content and run the checks. Our team steers, reviews and decides. That means days instead of months.
Clean HTML, structured data and real buttons and labels. AI crawlers read every page, and browser agents comparing providers find every field.
Static pages without a stack of plugins, served from a CDN. Fast for your visitors and for every crawler, with a budget for Core Web Vitals.
For example, you ask for an FAQ on every article about a service. Agents build it across all relevant pages and languages, following your style guide and your approved facts.
Insights from sales calls, Search Console, GA4, campaigns and your CRM become proposals for new pages and improvements. You approve or adjust.
Keyword research per country, translation with your industry's terminology, local rules and offers, and the review process you prefer: per country or central.
Our process
We check whether your site is readable for AI crawlers and whether your current platform is holding you back.
We record rankings, URLs, links, speed and AI mentions, so you can compare honestly after the launch.
Agents build and migrate, our team steers. Everything runs on a test environment first. Days to a few weeks, depending on the number of pages and languages.
We track the results. Changes across hundreds of pages now happen in one round, and search engines get an immediate signal through IndexNow.
Always all-in
A new service, a change in the law or a new market often means adjusting hundreds of pages one by one today. So it does not get done. Every plugin adds code, updates and risk, until the site becomes slow and fragile. And a new language costs a translation plugin or a second site, with all content maintained twice.
Meanwhile customers increasingly ask their questions to ChatGPT, Copilot or Perplexity, or read an AI answer in Google first. Those systems read your site directly, and they do not see everything: according to research by Vercel, the major AI crawlers do not execute JavaScript. Whatever appears only after loading does not exist for them.
“More people will solve it.” Every extra link in the chain is an extra queue. An organization that runs on AI agents responds faster and deals with things up front instead of after the fact.
“Every page has to be perfect.” Teams lose weeks on details. What counts is enough high-quality content, strengthened with your own knowledge, points of view and cases.
“A website is a project.” A site that stands still after launch starts ageing on day one. New pages, events, calculators and tools should be added in days, not months.
Today a new page passes through a briefing, a web agency, UX and UI design, a copywriter, a translation agency and a developer for the tracking. With an agentic website that happens in one sprint: structure, design, copy, translation and tracking in one round, in every language. One team steers, agents execute.
A few examples from our own projects, as estimates rather than measured averages:
| Task | Classic | Agentic |
|---|---|---|
| Changing one call to action in 120 places | Almost a day | 1 minute |
| Translating a site of about 100 pages into 4 languages | 2 to 3 weeks | 1 day |
| A new page in several languages, with tracking | Several days of work across several suppliers | One round |
Level 1: foundation. A strong structure and architecture, the right components, optimized for mobile, with trust signals and cases. This is the rebuild or migration.
Level 2: content at scale. Continuous publishing based on a topic map, in every language, checked and optimized. That is how we publish on customerimpact.be in Dutch, French, English and German.
Level 3: a learning site. Pages improve based on campaign and conversion data. A/B tests between very different pages, where the winner becomes the new standard.
With an agentic website the role of your team changes. They decide what needs to change, and why. Agents carry it out on every page and in every language. And they approve before anything goes live, always.
That comes with fixed ground rules. Every change sits on a preview link first and only goes live after human approval. Every change is logged in version control, so a previous version is back online in no time. Agents work with your style guide and a list of approved facts, not with whatever they come up with. And a person reviews important copy and translations.
An agentic website does not just translate, it localizes. We do keyword research per country, so every page uses the words people there actually type, in Google and in AI answers. The translation follows your industry’s terminology. Laws, prices, offers and cookie rules are adapted per country. Stuck in a translation plugin today? Read how to leave a translation tool without losing SEO, or look at our website translation services.
The code lives with you. If you stop working with us, you keep managing the site yourself, or with whoever you like. Customer data never goes to an AI model that trains on it, and we map privacy and cookies per country. Prefer to be at the controls yourself? Then we train your team and step in when needed.

Your website is no longer a business card, it is a living part of your organization. If every change still happens page by page and ticket by ticket, you are always too late. With agents the unit of work changes: not one page, but the whole site in one round, and a person decides.

The difference is not faster typing, it is the unit of work: not one page, but the whole site in one round.
Case studies
ResultX, a sustainability consultancy, is getting a new site in three languages, moved off Webflow and built in just over two weeks. Agents build, a second AI reviews every change, and every build runs 910 automated tests and 86 browser checks. The ResultX team edits the blog itself.
For our sister agency SEO GEO Agency we built a complete site in Astro with agents: 20 service pages, 65 knowledge articles, 68 glossary terms and the cases. Going from an empty project to 171 pages took two days, with structured data and a link check on every build.
We rebuilt customerimpact.be off Webflow, with agents. Google measures a load time of 1.5 seconds for the largest element with real visitors. On the same foundation the site grew from 18 to 1,520 clicks from Google per 28 days.

Briefly tell us what it is about. You get a personal reply from Tanguy or someone from the team, not a call centre.
A website built and maintained by AI agents, steered by people. You ask for a change in plain language, agents carry it out across all relevant pages and languages, and your team approves it on a preview link before anything goes live.
No. Nothing goes live without approval. Agents work with your style guide and a list of approved facts, and important copy and translations are reviewed by people.
Days to a few weeks, depending on the number of pages and languages. seogeoagency.be went from an empty project to 171 pages in two days, and the new ResultX site in three languages was ready in just over two weeks.
Translation and localization happen in days. The review happens at your pace, by whoever you choose: a local owner per country, one central reviewer, or publish first and adjust afterwards.
Not if the migration is done properly. We record a baseline first and redirect every old URL to the right new page. That is how customerimpact.be moved off Webflow, and it then grew from 18 to 1,520 clicks from Google per 28 days.
The crawlers of ChatGPT, Claude and Perplexity do not execute JavaScript. Whatever loads only after that, they do not see. An agentic website delivers clean, fast HTML with structured data, so AI systems can read every page.
Factor in what you no longer outsource: the agency, the translation, the developer. And what it is worth to have a campaign live days earlier. Changing one call to action in 120 places takes almost a day the classic way, and one minute the agentic way.
The code and the content are yours. You keep managing the site yourself afterwards, or with whoever you like. We also train your team to manage the site themselves.
Customer data never goes to an AI model that trains on it. Security follows best practices, and we map privacy and cookies per country.
Yes. Your team edits copy and blog articles in a simple CMS. For changes across many pages or languages at once, we use the agents.
From WordPress, Webflow, Wix and most other platforms. We rebuild in Astro, with static pages on a CDN.
