If you run a business and are experimenting with AI tools, you might be asking yourself whether Google can really tell if content was created by AI. This can be especially important for SEO, with worries that AI-generated text might be penalised or demoted.
Amid concerns over misinformation from AI-generated content, Google has rolled out tools like SynthID for content transparency. AI, especially tools like ChatGPT and Gemini, has taken off in popularity, with 47% of posts likely AI-generated, grabbing everyone’s attention with everything from AI-made cat videos to AI images created of action figures that look like us.
In this guide, we’ll look at how Google can tell if your content is written by AI, whether it matters, and how you can use AI to create more valuable content for your website.
Can Google Detect AI-Generated Text?
Yes, with reason. Google’s tools like Synth ID don’t care whether you’ve sourced the content from AI, but target unhelpful or spammy behaviour. Detection isn’t the goal, quality is.
In reality, Google’s focus isn’t on identifying AI but on filtering out all the spammers. The truth is, certain words and phrases can flag content as AI-generated.
It has been identified 305 words and 43 red flag phrases like “delve”,” well-crafted”, “as we conclude” and “transformative power”, that scream ChatGPT. Large Language Models also love a dramatic number of dashes. Even when you ask it to “humanise” the writing, a sprinkle of human editing is still needed to create memorable content.
Does Google Penalise AI-Generated Content?
Not exactly. Google makes it clear that its priority is to share content that includes expertise, authoritativeness, and trustworthiness, no matter how the content is produced. Google’s policy now targets “scaled content abuse” to detect AI style patterns, but what matters most is that content remains valuable and human-centred.
Yes, you should care; otherwise, content shared online or written information will become too manufactured and will lack personality. This means that as long as you edit AI-created content to ensure it still holds your personality and remove spammy words, you will follow Google’s policy.
How Accurate Are AI Detection Tools?
AI detection tools aren’t as accurate as you might hope, as a2023 study of 14 detection tools found that only five scored over 70% accuracy, and none exceeded 80%. Another detection platform showed 93% sensitivity on content, but text that had been modified by a human often reduced its accuracy.
AI detection tools are clearly a work in progress and have a long way to go before they can count as a useful tool.
What Is SynthID and How Does It Work?
SynthID is Google DeepMind’s watermarking system. It invisibly embeds a digital signature into content, text, images, audio, and video created with Google’s AI tools such as Gemini. Over 10 billion items have already been watermarked.
Google’s new SynthID Detector portal allows early testers to upload content and pinpoint watermarked portions. While detection can be powerful, it’s currently limited to watermarked content. Once SynthID has successfully made it through the teething stage, it will create transparency to boost trust and promote content authenticity.
How Can I Make AI-Assisted Content Safe for SEO?
A human editor’s touch makes all the difference. Whether through editing or adding personal insights, refining AI output helps reduce detectable AI-like patterns and boosts quality. As John Hinkley put it, “It’s a tool – like a piano is to a composer, or a chisel to a sculptor.” At Lumen SEO, we recommend applying Google’s E-E-A-T framework: Experience, Expertise, Authoritativeness, and Trustworthiness to AI-assisted content. Showcase your expertise, share real experiences, build authority with credible sources, and ensure trust with accuracy and transparency.
To make AI safe for SEO, always add real-world insights, fact-checked data, and your brand’s unique perspective. Edit drafts for tone and flow so they feel authentic and human. You can read more about how this improves rankings in our E-E-A-T blog.
Think of AI as a useful assistant, not the author itself, that helps you produce content that is efficient, credible, and search engine-friendly.
How to Use AI for Your Content (Without Letting It Write It for You!)
If you want to use AI the smart way, start with these three simple tips.
- Don’t copy and paste directly from AI: As tempting as it can be to publish AI’s completed work, use it as a framework or first draft. Take this as an opportunity to add your tone and personality to your content.
- Let AI be your proofreader, not your writer: As someone with dyslexia, AI has been a game-changing tool for me. I use it to catch spelling mistakes or grammar slips I might otherwise miss, giving me more confidence in the final quality of my writing.
- Brainstorm Ideas: We’ve all been there, staring at a blank page, unsure where to start. AI can help by taking the rough idea you already have and offering examples, angles, or suggestions to get the ball rolling. Think of it as a creative spark, not the final draft. It gives you momentum, but you’re still the one steering the direction. Unlocking Better Content with AI: Quality First, Tools Second
How Can We Help?
In summary, Google can detect AI-generated patterns, especially via watermarking efforts like SynthID, yet does not penalise AI content. But it will make red flags known, such as low quality, unhelpful, or spammy language, regardless of where it came from. Detection tools continue to improve but remain imperfect.
The secret lies in combining AI efficiency with a sprinkle of human oversight, your expertise, and uniqueness.
