In early October 2026, Google added to its guidance on creating helpful, reliable, people-first content a warning against deceptive authorship information. Fabricating creator profiles, with AI-generated headshots, made-up names or false credentials, is described there as a form of deception that makes a page untrustworthy to users and to its automated quality systems. The subject was already in the guidelines for its human raters; it now enters the public documentation written for site owners. Google announces neither a penalty nor a new ranking system. For a company that runs a blog, the practical question is to check who signs, with which photo and which credentials, before the next publication.
The facts
- In the section on who created the content of its guidance, Google now writes: avoid using deceptive authorship information. The examples given are AI-generated headshots, made-up names and false credentials used to make content appear as if it was written by human experts. The English page shows a last update on 5 October 2026, its French version on 7 October; according to Search Engine Journal, the version dated 1 October already carried this paragraph.
- Google files this practice under deception: any form of deception makes a page untrustworthy to users and to its automated quality systems, and is a signal of a low-quality page. The same page recalls that E-E-A-T (experience, expertise, authoritativeness, trustworthiness) is not a specific ranking factor and that its raters have no control over how pages rank.
- Search Engine Journal compared the new version on 2 October with a copy saved on 8 June, which went from the bylines advice straight to the How section without this paragraph. Search Engine Roundtable recalled on 6 October that Google had previously told it that it was not worried about faked author information. The Search Quality Rater Guidelines (version of 11 September 2025) already listed, in section 4.5.3, made-up author profiles and false credentials as deception to be rated Lowest.
The paragraph follows the advice to add bylines, in the section on who created the content
The guidance invites site owners to assess content through three questions: who created it, how and why. Under the first, Google encourages adding accurate authorship information, such as bylines, to content where readers would expect one, and linking those bylines to information about the person and the topics they write about. The new paragraph comes right after: fabricating creator profiles is deception, and deception signals a low-quality page.
The same update added a section defining the main content of a page and the four attributes raters assess: effort, originality, talent or skill, accuracy. Google gives as an example of low effort the use of generative AI to produce large amounts of text without human oversight or curation, and states that citing sources does not replace original work.
The guidelines Google's human raters follow to rate pages, the Search Quality Rater Guidelines, already covered the case. Their section 4.5.3, on deceptive pages, lists among deceptive information about content creators AI-generated content with made-up author profiles, built from AI-generated images or deceptive creator descriptions, and profiles that falsely claim credentials, such as posing as a medical professional. These pages receive the Lowest rating. Google states that raters' ratings do not directly influence ranking: they are used to check that its systems are working.
Google announces neither a penalty nor a new system, and a byline does not lift a page
The paragraph refers to automated quality systems without saying how they would identify a fabricated profile, as Search Engine Journal notes. No manual action, no ranking update and no effective date are announced. Google's page logging changes to its documentation records the 1 October change to the guidance on AI-generated content, and as of 2 October did not record the edit to the helpful content page.
The other side of the rule is known. In January 2024, Google's Search Liaison account said that bylines do not help pages rank better, Search Engine Journal recalls. The guidance confirms it in its own way: E-E-A-T is not a specific ranking factor, and Google gives more weight to trust signals on topics that affect people's health, financial stability or safety. A real byline is therefore not a ranking lever; a fabricated byline is now a declared signal of low quality.
Writing with an assistant remains allowed. Google's guidance on AI-generated content, updated on 1 October 2026, calls it critical to manually fact-check and review all AI-generated content before publishing, including title elements, meta descriptions, structured data and image alternate texts, and invites publishers to give context on how automation was used. The reproach targets the invented identity of the person who signs.
How to audit the bylines of a blog after this update
For two years we have kept meeting the same character on company blogs: a doctor with a catalogue smile, fifteen years of experience in a vague specialty, no trace outside the site. The checks below are our recommendations; Google has published no list of this kind.
- Inventory. Every name shown as a byline on the blog and on expert pages matches a real person who can be identified and reached.
- Headshots. Spot AI-generated faces or stock photos attached to a name. A byline without a photo is better than a portrait that belongs to nobody.
- Titles and credentials. A mention such as chartered accountant or fifteen years of experience must be justifiable on request.
- Author pages. The page linked to the byline holds a factual biography and links to profiles that exist: LinkedIn, publications, talks.
- AI-assisted content. Identify who reviewed and approved each article. That person signs; failing that, the company signs.
- Health, money, safety. Maximum requirement on these topics, to which Google says it gives more weight when it comes to trust.
| What the byline carries | What the guidance says | Fix |
|---|---|---|
| Made-up name with an expert biography | Fabricated profile, a form of deception | Replace with a real contributor or with the company's byline |
| AI-generated headshot or stock photo under a real name | Cited as an example of fabrication when used to suggest a human expert | Photo of the person, or no photo |
| Title or degree that cannot be justified | False credential | Remove the mention or justify it |
| Article written with AI, reviewed and signed by an identified person | Allowed; Google encourages explaining how automation was used | Keep the byline, mention the review |
| Article written with AI, published without review | The AI content guidance requires a manual check before publishing | Review, correct, then sign |
Removing every byline without an alternative solves nothing: the guidance encourages bylines where readers expect them. What remains is to write the internal rule, no fictional author, and to impose it on content providers in their contracts.
AIxH's view
This paragraph puts in writing a rule we apply on this site and for our clients: AI assists the writing, an identified person reviews, corrects and signs, and every author of our articles has a page pointing to their public profiles, like the members of our team. The same guidance encourages explaining how automation was used to produce a piece of content, when readers may wonder; we wrote it in our article on the September spam update. If bylines of uncertain origin are circulating on your blog, our search engine optimisation service can review them with your content, as part of an SEO audit, before the next publication.
