Does Google penalize AI-generated content?

Google is not scanning for AI watermarks. What matters more to the search engine is whether the content adds something new: personal experience, original data, useful tools, practical information, or other value for the user.

The new invisible watermark for Claude-generated texts might initially look like a problem for SEO specialists and marketers who use AI for large-scale content creation. However, the watermark itself is not the issue.

Google does not demote pages simply because AI was used during content creation. The search engine cares about something else: whether the material is useful, original, and genuinely answers the user’s search intent.

How Anthropic’s AI Watermark Works

On August 11, Anthropic confirmed that Claude’s text outputs now feature an invisible watermark. It applies to all models released by the company after August 2.

The model generates text by sequentially choosing the next word from a set of potential options. The watermark subtly influences this selection process, giving preference to a specific, secret portion of the vocabulary.

An individual sentence looks no different from standard human text. However, when analyzing several hundred words, this statistical pattern can be detected using a special cryptographic key.

Where this marker resides is equally interesting. It is not metadata that a CMS can strip during text upload. The watermark is embedded directly into the choice of words, which means it travels along with the text.

If you copy text from Claude and paste it into your CMS, the marker remains. At the same time, users cannot see it and cannot simply remove it with a single click.

Anthropic is not the only company moving in this direction. On August 2, the transparency code within the EU AI Act came into force, which envisions the labeling of AI content so that other systems can identify it. Similar requirements apply to other AI developers.

Against the backdrop of growing low-quality AI content, we can expect the number of such labeling mechanisms to increase.

If you have been using ChatGPT, Gemini, and Claude for several years to generate articles, service pages, and product categories at scale, your first thought might be:

“Google will find this watermark, flag our pages, and we will lose organic traffic.”

The watermark does exist. However, Google does not penalize content solely because it was created with AI.

It is worth looking deeper: if an AI watermark frightens you, the real problem might actually lie within your content itself.

What Google Actually Says

Let’s start with what Google officially states regarding AI content.

In February 2023, Google published its stance on AI-generated content. The core principle is straightforward:

“Appropriate use of AI or automation is not contrary to our guidelines.”

Regarding the impact of AI on search rankings, Google explains even more directly:

“Using AI doesn’t give content any special gains. It’s just content.”

In short, Google does not care who or what wrote the text; it cares about what the user ultimately receives.

The search engine chose not to engage in an endless arms race between AI generators and AI detectors. Instead, Google focused on the value a page delivers to the user.

This approach is reflected in Google’s spam policies, which define violations that can lead to manual actions. Out of 16 types of spam, generative AI is mentioned only twice.

The first case involves attempts to manipulate Google’s AI features; such actions fall under general anti-spam regulations.

The second case is significantly more critical for content marketing. It addresses scaled content creation:

“Using automation—including generative AI—to generate content at scale is a violation if the primary purpose is manipulating ranking in Search results rather than helping users.”

In that same policy, Google clarifies:

“Creating large amounts of unoriginal content that provides little to no value to users, regardless of how it is created.”

It is vital to pay attention to that last phrase: “regardless of how it is created.”

Google drew a direct parallel back in its February 2023 publication. About ten years ago, the search engine faced a similar boom in mass content generated by humans. Google noted that banning all content simply because humans created it would make no sense.

The same applies to AI.

If a hundred copywriters produce hundreds of shallow pages with no new insights, it is a problem. If an automated AI workflow does the exact same thing, the problem remains identical.

The issue is not AI itself. The issue is scale without originality, and creating content to manipulate rankings rather than to serve the user.

What Large-Scale Content Generation Looks Like in Practice

Now let’s look at what an AI strategy looks like in its most radical form.

In November 2023, the founder of an SEO agency called his experiment an “SEO heist.”

He downloaded a competitor’s sitemap, converted the list of URLs into article topics, and then used automation to generate approximately 1,800 pieces of content.

He published the results himself: in total, the site gained 3.6 million visits, averaging around 490,000 per month, while claiming that this traffic was hijacked directly from the competitor. The post detailing the experiment gained nearly 4 million views.

Search Engine Land reported the full story of this experiment. Eventually, even Google CEO Sundar Pichai learned about it: during an interview, he was shown the post and asked to comment on the situation.

The post about the SEO heist was shown to Google CEO Sundar Pichai during an interview.

And then, the experiment began to fall apart.

Over the following months, most of the gained traffic vanished. The website returned to roughly its previous metrics, and on certain parameters, dipped even lower.

If you overlay this case onto Google’s rules, the pattern is fairly obvious:

• A high volume of pages
• Zero added value
• Content creation purely to manipulate search rankings

All three criteria align.

That is precisely why the website was penalized—and along with it, other resources that employed a similar approach suffered the same fate.

Does AI Content Really Rank Worse?

Now let’s examine a study that might initially seem to contradict everything mentioned above.

Semrush analyzed 42,000 blog posts using an AI detector and categorized them based on their positions in search engine results pages (SERPs).

Among pages in the number-one spot, approximately 80.5% were classified by the detector as human-written, while only about 10% were flagged as AI content.

In other words, human-written content landed in the top spot about eight times more frequently.

However, jumping to the conclusion that “AI content cannot reach the top” misinterprets the study’s findings. The researchers themselves highlighted this distinction.

The issue is that an AI detector analyzes the final output, not the process behind its creation.

A page that a human genuinely put effort into can appear as high-quality, author-driven content even if AI was used during the writing process.

The same study notes that AI has already become a standard part of content production for most teams. Starting from roughly the fifth position downward, the gap between content classified as human-written versus AI-generated becomes significantly smaller.

So, the issue is not that AI content is incapable of ranking.

The real problem lies elsewhere: shallow, low-quality content cannot sustainably hold top positions in search results.

And an AI watermark changes nothing about that—neither for better nor for worse.

What Google Actually Values

If AI itself is not the problem, what factors does Google evaluate positively? There are several key aspects, none of which depend on who typed the text on the keyboard.

Effort

The first principle is directly outlined in the Search Quality Rater Guidelines.

These are the instructions Google uses to evaluate search result quality through human raters. While rater evaluations do not directly alter site rankings, the guidelines highlight the content characteristics Google trains its algorithms to prioritize.

Section 3.2 addresses evaluating the main content of a page:

“For most pages, the quality of the Main Content can be determined by the amount of effort, originality, talent, and skill that went into creating it.”

Google further clarifies what it means by effort:

“Effort: Evaluate how actively a person worked to create content that satisfies user needs.”

Section 3.2 of the Search Quality Rater Guidelines, where Google defines the concept of “effort.”

Importantly, the concept of effort is not limited to text generation alone.

Google notes that effort can manifest through developing page functionality or building systems that power the page. For instance, a page might offer a machine translation service.

In other words, a custom calculator developed for your website represents work and effort—even if a machine processes all calculations after launch.

Conversely, Google’s next example clearly illustrates where the boundary lies—effectively mirroring the SEO heist case mentioned earlier:

“Automatically generating thousands of pages by running existing free content through available translation software without supervision, manual oversight, etc., is not considered a result of effort.”

Thus, the core question is not who authored the text—human or AI.

The critical question is whether anyone put in the work to make that content genuinely useful.

Commodity vs. Non-Commodity Content

Effort serves as a general principle, but there is an even more practical criterion that Google has been addressing more directly in recent times.

In April, during Search Central Live in Toronto, Google representative Danny Sullivan presented a slide categorizing content into two types: commodity and non-commodity.

In short: generic content that anyone can generate versus content that carries unique, intrinsic value.

For the second category, Sullivan highlighted three core attributes: unique, specific, and authentic.

• Unique — Distinctive enough that competitors cannot easily replicate it.
• Specific — Tied to a real case study rather than built around generic advice.
• Authentic — Demonstrates firsthand experience, proving the author actively handled the situation described.

Examples clearly illustrate this contrast:

For a running shoe store:

• Commodity content: “10 Things to Consider When Buying Running Shoes.”
• Valuable, non-commodity content: “Why This Client’s Running Shoes Broke Down After 400 Miles”—a breakdown of a specific case detailing how the client’s unique running gait destroyed the shoe’s foam sole.

For a real estate agent:

• Commodity content: “7 Tips for First-Time Homebuyers.”
• Non-commodity alternative: “Why We Skipped the Professional Inspection and Saved $15,000″—a real-life account explaining how the agent personally inspected the drainage system and discovered PVC piping instead of concrete.

For an interior designer:

• Commodity content: “Kitchen Design Trends You Need to See.”
• Non-commodity alternative: “Why I Refused to Install Marble in a Home with Five Kids”—backed by actual stain tests using grape juice and turmeric to justify the decision.

The distinction between commodity and non-commodity content:

A commodity article could be written by almost anyone—or any AI model.

Conversely, a piece focused on a specific, real-world case can only be created by someone who actively experienced the situation firsthand.

At the same time, Sullivan emphasized that commodity content is not inherently bad. At times, straightforward, standardized information is precisely what a specific page requires.

Information Gain and Google’s Patent

This logic is not new for Google. In fact, it carries a formal name: information gain.

Google holds a patent titled “Contextual estimation of link information gain,” which evaluates a document based on:

“Additional information contained in the document compared to information from other documents already presented to the user.”

To put it simply: when your page merely regurgitates what ten other sites have already published, it matters little how well written the text is or who wrote it.

You are not contributing new information—therefore, you offer no additional value to the user.

Such content struggles to reach top search rankings. Even if a page initially ranks well, it risks losing its position over time as search algorithms discover content that offers users greater depth.

Semrush offers a comprehensive guide on information gain for those interested in exploring this approach further.

Information gain represents what your page adds to the body of knowledge already available in search results.

In the end, there is one question every creator should ask before publishing content.

It is less of an SEO tactic and more of a fundamental mindset shift in content creation:

“Is this piece truly helpful? Does it contain something unique? Does it deliver additional value to the user?”

If the answer to all three questions is “yes,” an AI watermark is the least of your concerns.

How to Make Content Non-Commodity

How do you transition from generic advice to content that genuinely delivers added value? Here are at least three simple directions to get started.

It makes no difference whether a page was created entirely by hand or if the initial draft was prepared by an AI model. What matters is that the final page offers something not found in the other ten search results.

Add Features that Required Real Effort

The simplest example is an interactive tool.

A custom calculator offers solid proof of real effort that cannot be replicated with a single prompt. Examples include:

• A tax calculator on an accountant’s website
• A sizing quiz in an online store
• A monthly payment calculator on a real estate agency site

Today, tools like these can be built using AI in literally a single day. And that is precisely the point.

You do not need to write all the code manually. What matters is that the tool exists, functions properly, and provides value to the user that standard text search results cannot match.

Move Beyond Text—Build Visual Content

A text-only page competes directly with dozens of other text-heavy pages on the exact same topic.

By contrast, a short video or an original chart built on your own data represents a format many competitors never bother to create. Scaling this type of content is also significantly harder.

After writing an article, you can:

• Record a concise video version of the material
• Slice it into multiple short-form videos
• Transform your proprietary data into a chart or diagram
• Design a unique infographic unavailable elsewhere

This approach works exceptionally well for updating older articles: adding video elements allows users to choose their preferred format—whether reading the article or watching it.

Original infographics and charts are equally effective—provided the underlying data belongs to you and its source is verifiable.

Share Insights Only You Possess

This is the core principle of non-commodity content applied directly to your work.

This may include:

• Results from your own projects
• Internal operational data
• Statistics drawn from actual practice
• Conclusions rooted in personal experience
• Opinions backed by specific, real-world examples

Buffer has embraced this approach since 2013. The company publicly shares its salary calculation formula, individual team member salaries, and an open revenue dashboard.

A competitor cannot simply copy these pages because the information relies entirely on Buffer’s internal metrics.

This was not a clever SEO strategy designed to target a specific keyword. Such content exists because the company is willing to publicly reveal what others do not.

That said, you do not need to expose your internal business operations in such extreme detail.

For example, a plumber who replaced 400 water heaters in a year knows which brands frequently require repairs and how long they actually last. That information might not exist on page one of Google simply because other writers lack access to that volume of real-world cases.

Similarly, an e-commerce store tracks which products are returned most often and the reasons customers state in return forms. Using this data, they can build a far more useful sizing guide that competitors will struggle to replicate.

Crucially, there is no need to name clients or disclose confidential details.

The specifics just need to be truthful and concrete enough for the reader to realize: the author has genuine, hands-on experience with these situations.

Another essential component is a real, verifiable author.

Include the author’s full name, a profile photo, professional background, and relevant expertise. Countless articles are still published anonymously, making it difficult for users, Google, and AI systems to evaluate who stands behind the information on the page.

What Does Google Actually Penalize?

Google applies search penalties to pages created at scale that offer little to no value to users and serve primarily to manipulate search rankings.

Websites hit by these penalties typically attempt to publish excessive amounts of content in short periods—without adding genuine value.

And an AI watermark has nothing to do with it.

It merely indicates the origin of the content—answering the question: “Was an AI model used in creating this text?”

That is not a criterion Google uses to build search rankings.

Instead, issues are far more likely to emerge at a different level—platform policies and brand reputation.

For instance, LinkedIn already allows users to report posts with the option “Seems like AI slop”—enabling members to flag content that appears low-quality or AI-generated.

LinkedIn added a “Seems like AI slop” option to its report menu. Watermarks may matter at the platform level, but they are not a Google ranking factor.

At this level, the real stakes involve user trust and brand equity—a challenge online platforms across the board are actively managing today.

Therefore, do not waste time attempting to strip AI watermarks from your pages out of fear of non-existent Google penalties.

Direct those efforts into the content itself instead.

Incorporate proprietary data. Conduct original research. Build a useful tool. Present a real case study. Add a video, diagram, or infographic. Involve an expert with specialized experience.

Above all, offer the user something new that they cannot find in alternative search results.

That is what truly dictates content quality—and no AI watermark can perform that work for you.
