Are AI Generated Websites Bad for SEO? An Honest Take

This question gets asked in two very different rooms. In one room, a business owner is staring at an AI site builder that promised a finished website in ninety seconds and wondering if Google will quietly bury it. In the other, a content team has been pasting raw model output onto a blog for six months and is watching traffic slide. Both are asking whether AI is the cause. Neither is asking the better question, which is whether the pages they shipped are good enough to earn a ranking.

I build websites by hand for a living, so you might expect me to say AI sites are garbage. I won't, because it isn't true, and because I use AI every day in my own process. What follows is the honest version: where AI helps, where it quietly sinks you, and how to tell the difference before Google does it for you.

Does Google actually penalize AI content?

No. Google's published guidance is that it rewards high quality content however it is produced and does not care whether a human or a model wrote the words. Its systems target low quality and unoriginal content, and AI made it cheap to mass produce exactly that. So the penalty is real, but it lands on quality, not on the byline.

Google made its position clear back in early 2023 and has held it since: using automation, including AI, to produce helpful content is fine, and using it to game rankings with scaled, unoriginal pages is not. The line is intent and quality, not authorship. That distinction matters because it means there is no AI detector quietly demoting your site. There is a helpful content system asking whether each page was made primarily for people or primarily for the search engine.

What did change is the March 2024 core update, when Google said it expected to cut low quality, unoriginal content in results by around 40 percent and tightened its policy against scaled content abuse. A wave of sites that had published hundreds or thousands of lightly edited AI articles lost most of their traffic almost overnight. The pattern was not "this site used AI." It was "this site published a high volume of pages that said nothing a dozen other pages did not already say." The AI was the delivery mechanism for the actual offense, which was thinness at scale.

So why do so many AI built websites still rank poorly?

Because the average AI build fails on substance and on engineering at the same time. The copy restates what already ranks, the pages are near duplicates of one another, the underlying code is heavier than it needs to be, and nothing on the page proves a real person with real experience made it. Any one of those is a drag. Together they keep a site out of the running.

Start with the copy. Ask a model to write a page about, say, gutter cleaning in your city and it will produce something fluent, grammatical, and almost perfectly average. That is the problem. It is a confident summary of the consensus, and the consensus is already ranking. There is no number a contractor would only know after a hundred jobs, no photo of an actual gutter, no mention of the one local quirk that makes your service different. Google's experience signals, the second E in E-E-A-T, have nothing to grab onto.

Then there is duplication. AI site builders work from templates, and templated location pages or service pages tend to come out 90 percent identical with the town name swapped. I have audited sites where forty "city" pages shared the same three paragraphs verbatim. That is the exact shape the scaled content abuse policy was written for, and Google's near duplicate detection collapses those pages into one or drops them entirely.

The engineering side is quieter but just as costly. Many AI and drag and drop builders ship a page that loads a megabyte of JavaScript, a heavy page builder framework, and a dozen blocking scripts to render a layout a hand coded page would deliver in a fraction of the weight. That tanks your Core Web Vitals and your mobile experience, which are real ranking and conversion factors. I dug into the gap between a builder's output and clean hand written code in custom versus Wix, and the page weight difference alone is often the whole story.

What does a thin AI page actually look like?

A thin AI page is fluent and empty. It answers the question generically, repeats phrasing you have seen on five other sites, cites no first hand experience or original data, and could have been written about any business in the category. If you swapped your name for a competitor's, nothing on the page would be wrong. That interchangeability is the tell.

Here is the test I run when a client asks me to review pages they generated. I read a paragraph and ask: could only this business have written this sentence? On a thin page the answer is always no. The sentences are true, polished, and completely portable. "Our team is committed to delivering exceptional results for every client" is real English that means nothing and belongs to no one.

Watch for the structural tells too. A genuine list has specific items in it. A thin AI list reads "quality, reliability, professionalism, and trust," four abstract nouns standing in for the concrete detail the writer did not have. Compare that to what a real list looks like on a useful page:

• A specific price or range, like "$180 to $240 for a single story 1,500 square foot home"
• A named tool, product, or method the business actually uses
• A constraint or tradeoff a competitor would not admit, like "we don't do tile roofs"
• A number that only comes from experience, like "we replace about one in twelve downspout brackets"

None of those come out of a model that has never run the business. They come from the owner. The moment you read a page and cannot tell which company wrote it, you are looking at content Google's systems are built to ignore.

How do you use AI for a site without hurting SEO?

Use AI where it is genuinely good, which is research, structure, and a fast first draft, then put a human in front of the words before anything ships. The person adds first hand experience, real numbers, specific examples, and cuts every sentence that could have been written about anyone. AI assisted is fine. AI abandoned on the page is what gets you demoted.

My own workflow looks like this. I let a model gather and organize what is already out there on a topic, which saves me an hour of reading. I'll have it draft an outline and stress test it for gaps. Sometimes I let it write a rough first pass of a section so I have something to react to instead of a blank page. Up to that point, AI is doing what it is good at, which is moving fast over ground that is already well trodden.

Then the real work starts, and it is human work. I rewrite the draft in my own voice, pull in things I have actually seen building for clients, add the specific numbers and tradeoffs a model cannot know, and delete every limp filler sentence it produced. I verify every factual claim against a primary source, because models state wrong facts with total confidence and a single fabricated statistic can sink the credibility of a whole page. The output is faster than writing from scratch and it carries experience the model never had.

If you are publishing at any volume, the discipline that protects you is simple to state and hard to keep: never let a page go live that a person has not made specifically better than the average page already ranking for that query. If you cannot add something real, do not publish the page. An empty page does not just fail to rank, it drags down how Google's helpful content system views the rest of your site.

Is it ever worth building a whole site with AI?

For a quick placeholder or a personal project where ranking does not matter, an AI builder is fine and honestly a reasonable use of an afternoon. For a business that needs to compete in search and convert visitors, no, not as a finished product. The output is a starting point at best, and the time spent fixing its code and copy usually erases the time it saved.

I want to be fair here, because the anti AI purists overstate this. If you need a one page site to point a QR code at, or you are testing whether an idea has any pulse before investing, generate something and move on. Speed is the entire value and you are not trying to outrank anyone. There is no shame in that and no SEO penalty for it either, because thin content only hurts when it is competing for queries it cannot win.

The trouble is when a real business treats AI generated output as the finished website. The copy needs rewriting for experience and specificity, the duplicate pages need consolidating, the bloated code needs replacing with something that passes Core Web Vitals, and the schema, internal linking, and crawlability all need to be built deliberately rather than guessed at by a generator. By the time you have done all of that properly, you have rebuilt the site. That is the honest tradeoff, and it is why I hand code client sites instead of generating them. The full reasoning behind that choice is in my breakdown of website builders versus custom coded websites, and the service itself is web development done by a person, not a prompt.

Hand coding is not a religious position for me. It is that I can control page weight to the kilobyte, write copy that actually demonstrates experience, and structure a site so search engines and AI answer engines can read it cleanly. A generator optimizes for "looks done in two minutes." Search optimizes for "is this the best result." Those are not the same goal, and the gap between them is exactly where rankings are won or lost.

What about AI search and answer engines, not just Google?

The same rule holds and gets stricter. ChatGPT, Perplexity, and Google's AI answers cite the source that says something specific and verifiable, not the one that restates the obvious. Generic AI written copy is the least likely thing to get cited, because it adds nothing the model did not already know. Original, experience backed pages are what these systems pull from.

It is a little ironic. The pages most likely to be quoted by an AI answer engine are the ones least likely to have been written by AI, because answer engines surface the specific claim, the real number, the first hand detail. If your page is a fluent summary of the consensus, the model already has the consensus in its weights and has no reason to cite you. If your page contains a price, a method, a result, or an opinion that exists nowhere else, that is the snippet it reaches for.

So the advice for AI search is the same advice for Google search, just with the volume turned up. Say something only you can say. That is the entire game in both traditional rankings and the AI driven answers that are eating into them, and no amount of generated text gets you there on its own.
