Google's author guidance: fake experts now called deception - and bylines still don't rank

Google dated the change October 1, 2026, according to Search Engine Journal, which reported that the Search Central page on creating helpful, reliable, people-first content now warns against fabricated creator profiles. That matters to anyone whose website has a blog, an About page or a team page. For years, adding a friendly face and an expert title to a page was treated as harmless polish. Google now puts a name on the practice when the face or the title is invented, and the name is deception.

Google now calls invented experts a form of deception

The new paragraph sits in the "Who (created the content)" section of Google's page, right after its existing advice to add accurate authorship information such as bylines, Search Engine Journal reported. Google's own page still says it strongly encourages adding accurate authorship information, such as bylines, to content where readers might expect it. Then it adds a warning.

The page reads: "However, avoid using deceptive authorship information. Fabricating creator profiles (such as by using AI-generated headshots, made-up names, or false credentials to make content appear as if it was written by human experts) is a form of deception. Any form of deception makes a page untrustworthy to both users and our automated quality systems, and is a signal of a low-quality page."

Google's page now says fabricating creator profiles, using AI-generated headshots, made-up names or false credentials, is a form of deception that makes a page untrustworthy to its automated quality systems. According to Search Engine Journal, a copy of the page saved June 8 went from the bylines advice straight to the "How" section, with no such paragraph. Compared with that copy, the October 1 version also includes a section defining main content.

That main content section, on Google's page, describes what raters look at, including effort. It says that using generative AI to produce large amounts of text without manual oversight or curation represents little to no effort.

The rule already existed for raters, now it is written for owners

None of this is new as an idea inside Google. Search Engine Journal pointed out that the Search Quality Rater Guidelines already tell raters to treat fake creator profiles, AI-generated author images and false claims of expertise as deception. Roger Montti covered that guidance in May 2025, the publication noted.

Section 4.5.3 of the rater guidelines lists AI-generated content with made-up author profiles, built from AI-generated images or deceptive bios, as one example of deception, according to Search Engine Journal. The same section lists author profiles that falsely claim credentials, such as posing as a medical professional. Raters are told to give pages that use deception the Lowest rating, according to Search Engine Journal.

The difference is the audience. Search Engine Journal noted that the people-first page says raters "have no control over how pages rank," while the new paragraph refers to Google's automated quality systems. In other words, the warning has moved from a manual for the people who grade Google's results to a page written for the people who run websites, and it now talks about the systems that do affect ranking.

The same day, Google told you to fact-check AI writing by hand

The author warning did not arrive alone. Google's documentation updates page lists an October 1 change to its guidance on using generative AI content, saying the update added information from the Search Quality Raters guidelines "to get our documentation in sync with our presentations we use at our developer events."

Barry Schwartz, executive editor of Search Engine Roundtable, reported that the updated document now uses the word "critical." Google's AI guidance now says it is critical to manually factcheck and review all AI-generated content for accuracy and trustworthiness before publishing. The page explains why: "generative models don't retrieve facts, but predict a likely sequence of words based on their training data," so outputs may contain inaccuracies, also known as hallucinations.

Google's AI guidance page adds that the review applies to more than the article itself. It names title elements, meta descriptions, structured data and alternate text for images, all of which can appear in search results. For online stores, the page says Google Merchant Center requires AI-generated images to carry IPTC DigitalSourceType TrainedAlgorithmicMedia metadata, and AI-generated product titles and descriptions must be labeled as AI-generated.

Schwartz wrote that Google does not often use the word "critical" in its help documents, and he wondered whether Google's September 2026 spam update is going after these things. That is his question, not something Google has said.

Why a clinic or a contractor should check the About page first

Put the two updates side by side and the message to a business owner is plain. Google wants content checked by a real person, and it wants the person named on the page to be real too.

Think of it like the licence number painted on a contractor's truck. Leaving it off is a missed chance to build trust. Painting on a number that belongs to nobody is a different thing entirely, and it turns a blank space into a false claim.

If your website shows a person who does not exist, or a credential nobody on your team holds, that is the exact practice Google's own page now names. This weighs most on health, money and safety topics. Google's people-first page says its systems give even more weight to strong experience, expertise, authoritativeness and trust on topics that could significantly affect people's health, financial stability or safety, which it calls "Your Money or Your Life" topics. The rater guidelines example Search Engine Journal cites, posing as a medical professional, is the one a clinic should read twice.

Search Engine Journal's own advice is narrow and practical: author pages and bylines are where you would check that a name, photo or credential is not being used to create a false impression of human expertise. If an agency, a freelancer or an AI tool writes your blog posts, that check is yours to make, because the page carries your business name.

What Google did not say, and why bylines still won't lift rankings

The other side: Google has explained the rule but not the enforcement. The new paragraph does not say how Google's automated systems would identify a fabricated profile, as Search Engine Journal noted. Google has not published what happens to a page or a site once deception is detected, beyond calling it a signal of a low-quality page. Search Engine Journal also reported that, as of its publication, Google's documentation updates page logged the AI content change but did not list the people-first content edit at all, which means changes to this page can happen quietly. And the rater guidelines' deception section is broader than the new paragraph, covering fake business details, impersonation and deceptive page design, so the owner-facing guidance may not be the full picture.

There is also a trap in the opposite direction. On bylines themselves, Google's Search Liaison account said in January 2024 that they do not help pages rank better, Search Engine Journal reported. Rushing to add author boxes to every page will not move rankings on its own. The point of the new paragraph is honesty, not decoration.

Bottom line

Google has taken a rule its raters already used and written it into guidance for site owners, on the same day it told them to fact-check AI content by hand. There is no new tool to install and no deadline. There is a short audit: every name, photo and credential on your site should belong to a real person who actually holds it.

A real staff member's name, or simply your business name, is safer than an expert who was invented to sound impressive. When did you last look at who your website says wrote your pages?
