A beautiful AI website is not yet a good website

With AI, a polished website goes live surprisingly fast. But sitemaps, page structure, content, consent and forms are not always delivered with it. Here is what to check before you publish.

A polished homepage. Smooth animations. A contact form at the bottom. With AI, you can have all of that on your screen surprisingly fast today.

But a website that looks finished is not automatically ready to receive customers.

When we review vibe coded websites, we come across missing sitemaps, incorrect URLs, unclear page structures and copy that mostly contains a lot of words. The front end is there. What is needed to make the website work reliably has not always been delivered with it.

The problem is not that the website was built with AI. The problem is that "looks good" is being used as the acceptance criterion.

What is vibe coding?

With vibe coding, you describe to an AI tool what you want to build. It generates the code, and you steer it with new instructions.

That makes building websites more accessible and can speed up the work considerably. At Saerens Advertising, we also use AI while building.

But speed does not replace control. A convincing demo does not yet prove that Google can process your pages, that your contact form delivers enquiries, or that your tracking respects visitors' consent.

1. Your website is online. Can Google do anything with it?

Opening a website in your browser is a different test from checking whether search engines can discover and index the right pages.

Take the sitemap: a file that tells search engines which pages you consider important. Sometimes it is missing. Sometimes it exists, but points to a test domain, deleted pages or incorrect URLs.

A sitemap is no guarantee of indexing. A small, well-linked website can be found without one. But if you provide one, its contents need to be correct.

The same goes for other signals. Is there still a setting active that prevents indexing? Does a page reference itself as the preferred version, or accidentally the homepage? Do old links keep working after a redesign?

"The page loads for me" answers none of those questions.

2. A big title is not necessarily a good page structure

What looks like a main heading can technically just be an enlarged piece of text.

A clear H1 and logically built subheadings help structure the content. That is useful for visitors, search engines and people using assistive technology.

A missing H1 does not cause an SEO disaster on its own. It is, however, a checkpoint you miss if you only look at the design.

The more useful question is: does someone immediately understand what this page is about, who it is for and what the next step is?

3. A lot of text is not the same as useful content

AI can easily write ten service pages. Or fifty local pages where only the town name changes.

But what does a potential customer learn from them?

"We deliver quality, service and tailor-made solutions" could appear on almost any company website. It says nothing about your approach, what is included or when your service does and does not fit.

Good content gives concrete answers. How does a collaboration work? What does the client need to provide? Which choices influence the price? Which experience or examples support your story?

Google does not prohibit AI content because it was made with AI. Producing pages at scale without added value, however, can fall under its spam policies.

Duplicate content does not automatically mean a penalty either. But near-identical pages without a purpose of their own are rarely a strong foundation.

The goal is not more pages. The goal is better answers to real customer questions.

4. A cookie banner is no proof that your privacy is in order

Not every website needs a cookie banner. If your site only uses strictly necessary cookies and no other technology that requires consent, the situation is different from a site with advertising tracking.

But as soon as consent is required, it must also be respected technically.

A banner that shows "decline" while non-essential cookies have already been set solves nothing. The same applies to a privacy statement that does not match the tools that are actually active.

So do not just check whether there is a banner. Test what happens before a choice, after accepting, after declining and when consent is withdrawn.

5. Your form says “sent”. Does the enquiry actually arrive?

A success message is easy to build. A reliable enquiry process takes more.

Does the message actually arrive? What does the visitor see if sending fails? Does the form work on a smartphone? Are input fields validated? Is there protection against abuse?

And if you measure conversions: do you record a successful enquiry, or only a click on the submit button?

That difference helps determine whether you make decisions based on real enquiries or misleading numbers.

The check before you publish

Checking an AI website before publishing: sitemap, structure, forms and consent under the magnifying glass

Test on the real domain, not just in your build tool's preview:

  • Are important pages reachable and not unintentionally excluded from indexing?
  • Does the sitemap contain the correct, final URLs?
  • Do internal links, redirects and error pages work correctly?
  • Do pages have clear titles, headings and a purpose of their own?
  • Does the content answer concrete customer questions, without invented claims or filler?
  • Do cookies and tracking respect visitors' choices?
  • Do form submissions arrive and are errors handled clearly?
  • Do navigation and forms work on mobile and with a keyboard?
  • Do you measure successful actions without unwanted double counting?

This is a first check, not a full technical, security or legal audit. But it already goes a good deal further than "the homepage looks good".

Build with AI. Deliver with control.

You do not automatically have to throw away an AI website and start over. Sometimes the foundation is solid and targeted improvements are enough. Sometimes the problems run deeper.

That needs to be investigated first.

At Saerens Advertising, we use AI to build faster, not to skip control. Design, content, findability and functionality belong to the same delivery.

Have you built a website with AI and are you unsure whether everything behind the scenes is right? Get in touch to have your website reviewed and to determine what should be tackled first.
