Businesses are filling their websites with AI-generated content that sounds like every other business in their industry, ranks for nothing, and convinces nobody to buy anything. Google updated its Quality Rater Guidelines in January 2025 specifically to target this kind of low-effort content. If your website copy could belong to any business in your sector, it effectively belongs to none of them, including yours.

Key Takeaways:

  • Google’s January 2025 Quality Rater Guidelines now explicitly mark mass-produced, low-effort AI content as “Lowest” quality regardless of how it was created
  • By May 2025, AI-written content made up roughly half of all new English-language web content according to SEO firm Graphite. “AI slop” was named Merriam-Webster’s Word of the Year for 2025.
  • Google’s E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) requires genuine first-hand knowledge that raw AI output cannot produce
  • Practical tests and industry research consistently show AI website builders producing near-identical layouts, structures, and copy regardless of the business being described
  • Raw AI output is a starting point, not a finished product. Using it as one is costing you enquiries.

The Homepage That Could Belong to Anyone

I looked at a website last month for a roofing company in Coventry. Their homepage opened with: “At [Company Name], we are committed to delivering high-quality roofing solutions tailored to your needs. Our experienced team of professionals brings expertise and dedication to every project.”

I have seen that sentence, or something within three words of it, on roughly forty websites in the last six months. Builders. Accountants. Solicitors. Plumbers. IT companies. It is the default output when someone types their business type into an AI tool and copies whatever comes back without touching it.

The roofing company had been trading for eleven years. They had done work on listed buildings. They had a specialist in heritage slate. None of that was anywhere on their website because none of it came out of a prompt.

Their website said nothing. It sounded confident while saying nothing. And Google, along with every potential customer who landed on it, noticed.

What Google Actually Thinks of This

Google does not penalise AI content simply because AI wrote it. That is worth saying clearly. The problem is not the tool. The problem is what businesses do with the output.

In January 2025, Google updated its Search Quality Rater Guidelines to explicitly address generative AI for the first time. The updated guidelines added AI-generated content directly to the “Lowest quality” category, stating that if almost all of the main content on a page is copied, paraphrased, auto-generated, or AI-produced with little originality or added value, it should receive the lowest rating. This applies even if the page credits its sources. Google’s Senior Search Analyst John Mueller addressed this directly at Search Central Live in Madrid in April 2025, calling on quality raters to flag content where the main content has been generated automatically with no meaningful human input.

Google employs between 10,000 and 16,000 human quality raters who use these guidelines to flag content, which then trains the automated systems that determine rankings.

The framework Google uses to assess content quality is called E-E-A-T: Experience, Expertise, Authoritativeness, and Trustworthiness. Of these four, Experience is the one AI content fails on completely and by design. AI has no first-hand knowledge of your industry, your clients, your processes, or your results. It cannot write about the job you completed in November that went sideways and how you fixed it. It cannot describe what separates your approach from the three competitors down the road. It can only produce a plausible-sounding version of what every business in your sector has already said, because that is what it was trained on.

Sites built on raw AI output have suffered significant traffic drops following Google’s core updates in 2024 and 2025, with documented cases losing the majority of their organic visibility. The businesses that ignored this and kept publishing are still trying to recover.

Your Customers Can Tell Too

It is tempting to assume that if content sounds professionally written, nobody will question it. That assumption is increasingly wrong.

By May 2025, AI-written content accounted for roughly half of all new English-language web content, according to analysis by SEO firm Graphite. Merriam-Webster named “slop” its Word of the Year for 2025, defining it specifically as low-quality AI-generated content produced in quantity. Mentions of “AI slop” across the internet increased ninefold in 2025 compared to 2024, according to Meltwater, with negative sentiment peaking at 54% in October. People are not just aware of this problem. They are actively annoyed by it.

Think about what your About Us page actually says. Does it mention your founding year and that you are “passionate about delivering results”? Does your services page promise to “work closely with clients to understand their unique requirements”? Does your homepage have a section about your “commitment to quality”?

None of those phrases mean anything. They are the verbal equivalent of a stock photo of someone shaking hands. They exist because AI generates them, they sound reasonable, and most business owners do not realise they are identical to what every other business in their sector has on their site.

Practical tests of AI website builders consistently demonstrate this problem. When the same prompt is given to multiple AI tools, the resulting sites share almost identical structures, section layouts, copy patterns, and design logic. A January 2026 piece from UK design agency Headon Creative described AI-built websites as instantly recognisable: black backgrounds, white text, gradient headlines, floating icons, and very little substance. When thousands of businesses generate sites this way, the output stops feeling modern and starts signalling exactly when and how it was built.

What AI Cannot Know About Your Business

Here is the practical problem. AI generates content by predicting what text should follow other text, based on patterns in its training data. It is very good at this. What it cannot do is know anything specific about you.

It does not know that your construction firm has completed over 200 projects in the West Midlands and that 70% of your work comes from repeat clients. It does not know that your accountancy practice specialises in contractors and has saved clients an average of £4,000 a year in tax. It does not know that your landscaping company has a specialist in Japanese garden design, or that your law firm was founded by someone who spent fifteen years at a Magic Circle firm before setting up independently.

Those specific details are what convert visitors into enquiries. They are the things a potential customer reads and thinks, “Right, these are the people I want.” AI cannot invent them. If you do not put them in, they are not there, and your website is left with the same filler content as everyone else.

The businesses that rank and convert in 2025 are the ones whose websites demonstrate genuine expertise and real experience. Not claimed expertise. Demonstrated expertise. Case studies with actual outcomes. Specific processes that reflect how the business actually works. Testimonials that go beyond “Great service, would recommend” and into what the client actually experienced.

An Ahrefs analysis published in April 2025 examined 900,000 newly published web pages and found that 74.2% contained AI-generated content. Yet Google’s own data shows that 86% of pages actually surfaced in Google Search were human-written. The implication is straightforward. Generic AI content is being produced at enormous scale and failing to rank at nearly the same rate.

The Fix Is Not Complicated

The answer is not to avoid AI tools entirely. Used properly, they are useful for structure, for first drafts, for generating options. The problem is treating the first draft as the finished product.

Every piece of content on your website should pass a simple test before it goes live. Could this sentence appear on a competitor’s website without anyone noticing? If the answer is yes, rewrite it.

Replace generic claims with specific ones. “We have years of experience” becomes “We have completed over 150 loft conversions across Birmingham and the surrounding area since 2009.” “We are committed to quality” becomes “Every project includes a full snagging inspection and a twelve-month workmanship guarantee.” “We work closely with our clients” becomes a description of your actual process, step by step, in plain English.

Add the things only you can add. Your team. Your real results. The specific areas you work in. The types of projects you take on and the ones you turn down. Why you started the business. What you have learned along the way.

I worked with a plastering company in Leicester earlier this year. Their website had AI-generated content on every page. It read perfectly well and said absolutely nothing. We rewrote every page using information pulled from two hours of conversation with the owner. Specific projects. His background in heritage restoration work. The types of properties he specialises in. The fact he refuses to use spray plaster.

Within three months, enquiry rates from the website had increased substantially and he was ranking for local search terms he had never appeared for previously. Same website. Same structure. Entirely different words.

The words matter. The specific, human, experience-based words that only your business can provide. Everything else is slop.

What To Do This Week

Pull up your homepage and read the first paragraph. Then ask yourself honestly whether it could have been written about any business in your industry. If it could, it needs rewriting.

Do the same for your About Us page, your service pages, and any blog content published in the last twelve months.

Where content is generic, replace it with specifics. Real numbers. Real locations. Real outcomes. Real details about how you work. If you are not sure where to start, talk to someone who can help you extract that information and turn it into copy that actually represents your business.

Generic AI content is not a small problem. It is the difference between a website that generates enquiries and one that sits there looking the part whilst doing absolutely nothing.
