Google updated its guidance on using generative AI content on October 1, 2026, lining it up with the Search Quality Rater Guidelines. On October 7, Google DeepMind opened its SynthID Detector to the public. Together, the two announcements revived a familiar question: can Google tell when a page was written with AI, and will it hurt the page?
Google AI content guidelines for law firms, like those for every other site, answer a different question. They are about whether a page is accurate, whether it adds something, and whether a site is churning out pages in bulk.
Google’s updated guidance does not ban AI-written pages.
It warns that generating many pages without adding value can break its scaled content abuse policy, and it says AI content should be fact-checked by a person before publishing. SynthID Detector checks images, video and audio, not written text.
Myth 1: Google Penalizes Any Page Written With AI
The belief that Google penalizes any AI-written page is not what its guidance says. AI can help with research and with organizing original content, according to Google’s guidance on using generative AI content. The warning is narrower: using generative AI tools to generate many pages without adding value for users may violate Google’s scaled content abuse policy.
Scaled content abuse is defined in Google’s spam policies as “when many pages are generated for the primary purpose of manipulating search rankings and not helping users.” The problem is volume without value, whatever tool made it.
Myth 2: Google Can Scan a Law Firm Blog Post for an AI Watermark
The belief that Google scans blog text for an AI watermark mixes up two separate things. According to Google DeepMind’s SynthID Detector announcement, the tool lets anyone check whether an image, video or audio file was made with AI from Google or its partners, which include OpenAI, NVIDIA and Kakao.
The announcement does not list written text as something the public tool checks, and it does not connect the tool to Search rankings. For a law firm, time spent worrying about detection is better spent checking facts.
Myth 3: The Rater Guidelines Decide Rankings
The belief that quality raters decide rankings is one Google’s guidance addresses directly. The page points to sections 4.6.5 and 4.6.6 of the rater guidelines, which cover scaled content abuse and low-effort, low-originality content, and notes that “their ratings don’t directly influence ranking.”
The guidelines are still useful as a self-check, because they describe what Google’s raters look for in low-effort, low-originality content. Pages written in a hurry, by AI or not, can fit that description, for many of the same reasons law firm copy sounds the same.
A Review Routine Before an AI-Drafted Page Goes Live
Google says it is “critical to manually factcheck and review all AI-generated content for accuracy and trustworthiness” before publishing. For a law firm, that review matters twice, because lawyer advertising rules prohibit false or misleading communications, and some states, such as D.C. under its Rule 7.1, also cover assertions that cannot be substantiated.
A review routine built on Google’s guidance:
- Check every statement of law against the statute, rule or court page. Google notes that generative models can produce errors.
- Check the parts readers don’t see, including titles, meta descriptions, structured data and image alt text.
- Add what only the firm knows, such as how a local court handles a step.
- Consider telling readers how the content was made, as Google’s page suggests.
- Cut anything the reviewer can’t confirm.
A machine-drafted Spanish page needs the same review, plus a decision on translated versus original Spanish content.
Frequently Asked Questions
A law firm can use ChatGPT or another AI tool to help write blog posts. It says all AI-generated content should be fact-checked and reviewed before publishing, and it warns against generating many pages that add no value for readers.
Google’s search guidance does not require a label on AI-written web pages. Separate labeling rules apply to AI-generated product data in Google Merchant Center, which does not cover law firm blog posts.
Scaled content abuse is Google’s term for generating many pages mainly to manipulate search rankings rather than help users. Google lists using generative AI tools to create many pages without adding value as one example.
The public SynthID Detector checks image, video and audio files for SynthID watermarks from Google and partner AI tools. Google DeepMind’s October 7, 2026, announcement does not list written text among the file types the public tool checks.

- The guidance points to rater guideline sections on scaled content abuse and low-effort content.

Following Google AI Content Guidelines on Law Firm Pages
Google AI content guidelines for law firms come down to a standard lawyers already know: say only what you can support, and make the work worth reading.
For firms using AI drafts, the change to make is in the process, not the tool. Assign a reviewer, check every fact at its source, and add the local knowledge a model cannot have. Firms still weighing what AI tools do to a firm’s visibility can start with one page and measure the result.
Lexicon’s legal content experts handle legal blogging for firms that want AI used for research and a person accountable for every claim. Call 877-486-8123 or contact us online to talk about how your drafts get reviewed today.
