Your AI-built website looks great. That’s exactly the problem.

You used Cursor, Lovable, Claude, or one of the other AI tools to build your website. It came together fast. The design looked polished. You shared it on LinkedIn and the comments rolled in: “Looks amazing!” “So clean!” “AI is the future!”

So you moved on to other things. Why wouldn’t you? The site looks professional. It feels done.

But months later, the bookings aren’t coming the way you expected. You’re not getting enough inquiries, or not the right kind. You’re not showing up in Google. Visitors land on your site and leave without taking action.

The instinct is to tweak the design. Make it bolder, more eye-catching, add more content. But design isn’t the problem.

What’s happening underneath is.

I know this because I audited 10 AI-built websites. Not a theoretical analysis, but real sites built by real solopreneurs with real tools. The first was a friend’s site that I checked as a favor. The other nine came from LinkedIn posts where people proudly shared what they’d built.

Everyone was looking at the design. Nobody checked under the hood. I did. And I found the same problems in every single one.

What’s actually going wrong (and why you can’t see it)

These problems aren’t technical nitpicks. Each one directly affects whether your business gets clients, gets found, or stays out of legal trouble. And they’re all connected: a site with bloated images loads slowly, ranks lower in search results, emits more carbon. One problem compounds into several.

For each category below you’ll read: what’s at stake for your business, what I found across the 10 sites, and what’s causing it.

Speed

Your website has about 3 seconds to load before visitors start leaving. They never see your offer, your expertise, or your call to action. For a solopreneur whose website is a primary channel for getting clients, that’s revenue walking away. Above 5 seconds, research shows you lose up to 90% of bookings.¹

“But everyone has fast internet in 2026,” I can hear you say. Not on the train. Not on rural mobile connections. Not on Deutsche Bahn WiFi. Not in a cafe with 30 people sharing one router.

Only 1 out of 10 sites loaded in under 3 seconds on mobile (Google’s recommended threshold). Three took over 8 seconds.

What’s causing it? Heavy, unoptimized images are the biggest culprit. Photos uploaded straight from the camera without compression, way too large for a screen (1920px is all you’ll ever need). One site had a 4 MB logo. Another had 21 MB of images on a single page.

On top of that, most sites were loading unused code: files the page doesn’t even need but downloads anyway. Plus a font file that weighed 1MB. All of it adds up.

AI doesn’t question any of this. You upload a photo from your camera or Unsplash, it places it at full size.

CO₂ emissions

Website emissions and speed are two sides of the same coin. The heavier your site, the more energy each page view consumes in data centers, in transit, and on your device, and the slower the site loads. So even if environmental impact isn’t your primary concern, the performance impact should be. And if you work with clients in the sustainability space, your website’s carbon footprint is a credibility issue.

8 out of 10 sites received an F rating for carbon emissions. I checked each site using the Website Carbon Calculator. Only 4 sites came in below the global average of 0.41g of CO2 per page view. The other 6 ranged from 0.44g to 2.36g, with the heaviest site dirtier than 97% of all websites globally.²

The cause is the same as with speed: huge images, fancy animations, heavy Javascript code. These things seem to be “trendy” somehow, so that’s what AI produces if you prompt “sleek” or “modern” website. Plus, AI makes “more” cheap and easy, so you keep adding sections, images, and effects. Nobody’s there to check the weight, page speed, and emissions.

Privacy

If you’re based in the EU or serve visitors there, GDPR applies to your website. Tracking visitors without their consent or operating without a privacy policy isn’t a grey area. It’s a compliance gap that can result in fines of up to 300,000 EUR. And “I didn’t know my site was tracking people” is not a defense.

9 out of 10 sites tracked visitors without consent. They used Google Fonts or Google APIs loaded from Google’s servers. Every page load sends visitor data, including IP addresses, to Google. Under the GDPR, that requires explicit consent before the font even loads. Only one site was clean.

9 out of 10 had no proper privacy policy. One privacy policy link led to a 404 error page. Another had a footer label that said “Privacy” but wasn’t even a clickable link. Seven had no privacy policy at all.

Three sites had third-party cookies on top of that. Only one of those three actually had a cookie policy in place.

If your business stands for doing things right, a website that tracks visitors without consent works against everything you represent.

Security

Getting hacked costs time, money, and reputation. If your site stores personal data (even just contact form submissions), a breach can turn into a privacy violation on top of that. For solopreneurs, recovering from a security incident can mean weeks of lost work.

Every single site was missing security basics. Not one had all security headers and content policies in place. Without them, your site is leaving doors open that should be locked. Most solopreneurs don’t even know these doors exist, let alone that they’re unlocked.

Two sites scored a B on security. One scored an F. The rest landed on C or D.³

While everyone’s complaining about how insecure and easy-to-hack WordPress is, nobody seems to care about what AI does.

Accessibility

Accessibility isn’t just about people with disabilities:

• A form that can’t be filled by keyboard alone frustrates people who spend a lot of time on the computer.
• Low text contrast affects people over 40 and everyone reading in bright sunlight.
• Small buttons frustrate anyone on a phone. Every accessibility issue is a visitor who can’t use your site properly, and that’s a booking you’ll never know you lost.

Plus, SEO and AI bots read your site the way a screen reader does. They depend on proper HTML code, correct heading structures, and alternative text for images. The same structural issues that lock out visitors also lock out search engines.

I tested accessibility scores only with Lighthouse, which gives you a score of 1-100. Accessibility scores across all 10 sites ranged from 87 to 96. Those numbers sound reassuring. They’re not.

Automated tests like Lighthouse only catch surface-level issues: missing alternative text, some color contrast ratios, missing link text. But a score of 92 doesn’t mean your site is accessible. It means the automated test didn’t find certain categories of problems.

Here’s what those scores were hiding:

• Contrast issues on 6 out of 10 sites. Text that doesn’t have enough contrast against its background, making it hard or impossible to read.
• Heading order problems on 5 sites. Screen readers rely on heading hierarchy (H1, H2, H3) to navigate a page. When headings skip levels or are used for visual sizing instead of structure, navigation breaks down.
• Missing main landmarks on 4 sites. Landmarks are HTML elements that help screen readers identify the main content area, navigation, and footer. Without them, users have to wade through every element on the page.
• Small touch targets on 2 sites. Buttons too small to tap reliably on mobile.
• Buttons without accessible labels. A sighted user sees a button. A screen reader user encounters a blank.

My favorite accessibility issue in this test: black text on dark green background on the primary CTA in the mobile menu. Nobody can read it. But the website owner didn’t think of checking their site on mobile.

And AI doesn’t catch them because—again—it builds what it has seen on the wider internet: Even in 2026, almost 96% of the top 1 million websites have accessibility errors (on average 56 errors per page to be specific).⁴

SEO

SEO determines whether people find you through Google at all. And everything I say here for SEO applies equally to AEO, GEO, and AIO.

If your site isn’t properly set up for search engines, it doesn’t matter how good your content is. Nobody will see it. All of these depend on the same technical foundations: clean HTML, proper metadata, structured content, and crawlable links. And SEO problems are silent: you don’t see the traffic you’re not getting. You just notice, sometimes months later, that nobody’s finding you through search.

6 sites had SEO scores below 100, ranging from 75 to 92. Again, those look adequate. But everything under 100 means a rookie mistake.

Here are some SEO errors:

• Missing meta descriptions on 5 sites. This is the text snippet that appears in Google search results beneath your page title. Without one, Google pulls random text from your page. That rarely represents your business the way you’d want.
• Broken or invalid robots.txt files on 2 sites. This is a small file that helps search engines find and crawl your pages. If it’s broken, Google might not index your site at all. You could have the best content in your industry and nobody would find it.
• Links that search engines can’t follow on 1 site. Not all links are created equal. Some are built in a way that looks clickable to you but is invisible to Google. If your site uses those, you miss out on an easy ranking boost.

Unlike with accessibility, there’s no data showing these SEO mistakes are common on the wider web. So here’s my guess why this happens: most business owners don’t know that a meta description, a valid robots.txt, or properly structured links even exist. You can’t prompt for something you’ve never heard of.

AI-built vs. professionally built: one website, side by side

A friend built her one-page solopreneur website with Claude Code. When she showed it to me, I offered to run my Solopreneur Website Check on it as a gift.

The Website Check is based on the 5 Solopreneur Website Foundations: the framework I use for every website I build. It covers Strategic Clarity, Professional Branding, Intuitive UX, Independent Technology, and Ethics & Sustainability. The first three held together on her site. Not flawless, but decent. The technology and ethics foundations told a different story.

Here’s what I found, compared to what I typically deliver with The reLaunch.

Speed. Her site took 14.3 seconds to load on mobile. My builds average 2.8 seconds. The main culprit: large images with no compression, no modern format, no adaptive sizing.

Carbon. Her site generates 2.36g of CO2 per page view, dirtier than 97% of websites globally. My builds average 0.02g, cleaner than 98% of sites, hosted on 100% renewable energy. (She works with clients in the sustainability space. Those numbers matter.)

Privacy. Google Fonts loaded, tracking every visitor without their knowledge. No cookie banner. No privacy policy. This can get you fines up to €300,000 in the EU.

SEO. Claude forgot to add a meta description. My friend didn’t even know what that was. A one-line problem that directly affects how her site shows up in search results.

On top of that: the same accessibility issues (contrast, keyboard navigation, heading structure) and missing security headers like with every other site tested. Not one of these issues was flagged by Claude.

Why AI keeps making these mistakes

These aren’t random oversights. They’re systemic. And they come down to three things.

AI is a copycat (or stochastic parrot if you want to use fancy nerd language). It generates structure based on patterns from millions of websites. Most of those websites don’t meet modern standards themselves. AI learned from them and reproduces what it saw. The result isn’t a bad website. It’s a website that reflects the average of what exists online, not the standard your business should meet.

AI gives you what you prompted. Nothing more. You didn’t prompt “add a privacy policy,” “compress all images,” “add security headers,” or “make sure the heading hierarchy is correct.” AI is responsive, not proactive. It won’t flag that your 4 MB logo should be 4 KB.

You can’t catch what you don’t know to look for. You may not know that you need to check your mobile menu to catch a button nobody can read. You may not know what a robots.txt is, let alone that yours is broken. You probably can’t tell that your site is one complaint away from a 300,000 EUR fine.

“If you don’t know what quality output looks like, AI won’t save you. […] AI only makes sense if you use it to amplify what you already know and do well, not as a hack.”

— LinkedIn comment by Nick Broekema

That matches what I see every day. I use AI in my own design workflow. Many designers do. The difference: We know what to direct the AI to do, what to check, and what to fix. The tools work well in the hands of someone who already has the expertise.

The foundations your AI-built website is missing

If you’re a solopreneur selling services via your website, here’s what you actually want and need: A website that loads on Deutsche Bahn WiFi. That shows up in Google. One where people and bots alike can actually read your content and navigate your site. That’s the baseline. Not a bonus.

If you’ve realized your AI-built website is holding you back, The reLaunch replaces it with a professional one. Every site I build is based on the 5 Solopreneur Website Foundations. Each one directly affects your bottom line:

• Strategic Clarity. Attracts right-fit clients who are ready to buy, not tire-kickers.
• Professional Branding. Builds trust before the sales call, so you stop defending your prices.
• Intuitive UX. Guides visitors to book, instead of losing them to confusion.
• Independent Technology. No slow loading, no security gaps, no missed search traffic.
• Ethics & Sustainability. No fines, no lawsuits, no credibility gaps with impact clients.

When these five foundations work together, your website doesn’t just look sleek. It actually gets you clients.

How to know whether you need a redesign

I can hear you say:

“But I’m not sure I need a full redesign”

That’s a fair response. And you might be right.

My done-for-you website redesign The reLaunch is a true overhaul, so that we get all five foundations right. But not every AI-built website needs to be torn down and rebuilt. Some need targeted fixes. Others need a deeper reThink. The problem is: you can’t make that call without knowing what’s actually going on under the hood.

That’s exactly what The Website Check is for.

I run your site through the same checks I used on the 10 AI websites: privacy, security, speed, carbon, accessibility, SEO, plus all the other foundations. You get a detailed report of what’s working, what’s not, and what to fix first.

It’s not a sales pitch for a redesign. You’ll know exactly where your site stands and can decide your next step from there, whether that’s fixing things yourself, hiring someone to help, or realizing your site is in better shape than you thought.

For the global average, last reported numbers at Website Carbon were from 2023. So, I looked at the 2026 State of the Web report to calculate a median weight for all websites tested (weighted average for both desktop and mobile) and ran that trough the SWDM v4.
