The “Vibe-Coding” Trap: Why AI Code is Different

Before AI took over the digital world by storm, technical debt was usually the result of “cutting corners” to meet a deadline. It was human error, documented and known.

In 2026, the debt will be different. It’s automated debt. AI models are “probabilistic,” not “architectural.” They are brilliant at predicting what the next line of code should look like based on billions of lines of training data, but they have zero understanding of your specific business logic or long-term goals.

When an AI generates code, it often prioritises “functional completeness” over “structural integrity.” It will give you a script that works, but it might duplicate a function that already exists elsewhere, import three unnecessary libraries, or ignore your team’s established naming conventions.

This leads to a fragmented codebase where every new feature feels like it’s being bolted onto a house made of mismatched bricks. Eventually, the weight becomes too much. This is exactly why digital marketing (and development) takes super-powers—because it requires the human ability to see the “big picture” that an LLM simply cannot perceive.

How Code Bloat Kills Your 2026 SEO

You might be thinking, “If the site works, why does the code matter?” It matters because of the Google December 2025 Authenticity Update. Google’s latest algorithm isn’t just looking at your words; it’s looking at your “Total Page Experience.” AI-generated code is notorious for “Code Bloat”—extra, unnecessary lines of JavaScript and CSS that slow down your site and confuse search crawlers.

When your site is bogged down by “AI Slop,” your Core Web Vitals take a hit. In the new era of Generative Engine Optimisation (GEO), AI “Answer Engines” like Gemini and Perplexity need to be able to parse your site in milliseconds. If your code is a tangled mess of AI-generated redundancies, those engines will simply skip you and cite a competitor who has a cleaner, more authoritative site.

This is why proper technical optimisation is no longer an “optional extra.” It is the barrier to entry for being seen at all in 2026.

The Financial Cost: Speed is a High-Interest Loan

The biggest irony of AI-assisted coding is that it’s actually making us slower in the long run. 2025 data showed that while initial coding was 20% faster, the time spent debugging and refactoring increased by nearly 40%.

If your team is spending 60% of their week fixing “weird bugs” caused by AI-generated modules that don’t talk to each other, you aren’t saving money. You are paying a “debt tax.” This friction eventually kills your ROI. If you want to see how this impacts your bottom line, look at how conversion rate optimisation relies on a fast, predictable, and clean user journey. A “debt-heavy” site is a leaky bucket for your marketing spend.

4 Ways to Stop the Rot (The Platform81 Way)

You can’t put the genie back in the bottle—AI is here to stay. But you can manage it “properly.” Here is how we recommend keeping your codebase in fine fettle.

1. Implement “Human-First” Workflows

AI should be the “intern,” not the “architect.” Every line of code generated by an AI must be treated with suspicion. If a developer cannot explain exactly why the AI chose a specific logic path, it shouldn’t be merged. We’ve talked about this before: protecting your work-life balance is only possible when you aren’t spending your weekends fixing “ghost in the machine” bugs.

2. Get a “Proper” Technical Audit

Most businesses have no idea how much debt they’ve accumulated over the last two years. They just know the site feels “heavier.” A comprehensive website audit is the only way to find out where the AI-generated bloat is hiding. We look for redundant scripts, hallucinated dependencies, and structural inconsistencies that are dragging down your performance.

3. Shift to Proactive Maintenance

The “set it and forget it” era of web development is dead. With the pace of AI evolution, code that was “fine” six months ago might be obsolete today. To stay ahead, you need a dedicated website maintenance and support plan. This isn’t just about “fixing what’s broken”; it’s about “refactoring” (tidying up) your code regularly so the debt never reaches a crisis point.

4. Feed the AI Better Context

If you are going to use AI, don’t just give it a blank prompt. Give it your style guide, your architectural standards, and your existing component library. The “mess” happens when the AI is left to guess. The more context you provide, the less debt it generates.

The “Stockport Perspective” on AI

Look, we’re all for innovation. We love a tool that makes life easier as much as the next person. But there’s a difference between “working fast” and “working well.”

In 2026, the businesses that will dominate page one aren’t the ones that generated the most code; they are the ones that maintained the best code. They are the ones who realised that account management is the backbone of any successful campaign, because it takes a human to manage the expectations and the ethics of these new tools.

Don’t let your business become a cautionary tale of “AI Slop.” It’s time to roll up our sleeves, clear out the debt, and build something that actually lasts.

Frequently Asked Questions

Can’t AI just fix the technical debt it created? 

Not really. That’s like asking the person who made the mess to “clean it up” without giving them a mop. AI can help identify patterns, but it takes a human architect to decide on the best structure for your specific business.

Is technical debt visible to my customers? 

Indirectly, yes. They’ll see it in the form of slow loading times, broken forms, or “janky” animations. Even if they don’t see the code, they’ll feel the importance of website maintenance (or the lack of it) in the user experience.

How do I explain the cost of “refactoring” to my boss? 

Tell them it’s like servicing a van. You can skip the oil change to save fifty quid today, but you’ll be paying five grand for a new engine in six months. Refactoring is the “oil change” for your digital business.

Does AI code bloat affect my SEO rankings directly? 

Yes. Google’s 2026 Authenticity Update specifically penalises sites that have poor performance due to unoptimised code. If your site is “heavy,” it won’t get cited by AI Answer Engines, period.

Will AI ever write “perfect” code? 

Maybe one day, but we aren’t there yet. Until an AI can understand your specific brand, your unique user base, and your long-term business strategy, it will always need a human expert to keep it on the straight and narrow.
