Google adds main content, four rater attributes and a fake-author warning to its helpful content guidance

Google added new text to its "Creating helpful, reliable, people-first content" page on Search Central, and the page shows a last-updated date of 1 October 2026 UTC. The additions define "main content", describe four attributes that Search Quality raters assess (effort, originality, talent or skill, and accuracy), and warn against fabricating creator profiles such as AI-generated headshots, made-up names or false credentials. Search Engine Roundtable and Search Engine Journal both reported the change on 2 October 2026.

What Google changed on the helpful content page

The page lives at Google Search Central and is the document Google points site owners to when they ask what "helpful" means. Its headings, in order, include "Self-assess your content", "Focus on people-first content", "Get to know E-E-A-T and the quality rater guidelines", "Main content" and a "Who, How, and Why" block. The 2 October reports describe three additions to that structure: a paragraph on main content, a short section on how raters evaluate it, and a paragraph in the "Who" part about deceptive authorship.

Search Engine Roundtable, written by Barry Schwartz, framed the update as two additions: a main content section and a section on the four rater attributes. Search Engine Journal, written by Matt G. Southern, focused on the third piece, the fake-author warning, and compared the live page with an archived version from 8 June, which did not contain that paragraph. Neither report gives a rollout date or a ranking-system name, because Google gave none.

What is new here versus what RA covered on 2 October

On 2 October 2026 Relevant Audience published a post about a different Google document: the guide on using generative AI content, where Google added a sentence saying it is critical to manually fact-check and review AI-generated content before publishing, including titles, meta descriptions, structured data and image alt text. That post is about a different page, and it is not repeated here.

This post covers the helpful content page itself. Three things are new in this coverage:

• The definition of main content and the statement that its quality is one of the most critical factors for assessing page quality.
• The four rater attributes, abbreviated EOT/SA by Search Engine Roundtable's headline: effort, originality, talent or skill, and accuracy.
• The warning against fabricated creator profiles, which Search Engine Journal says was absent from the 8 June archived copy.

The two changes landed on the same day, and both draw on material from the rater guidelines, so reading them together is reasonable. They are still separate edits to separate pages, and a site owner should check both.

Main content: what Google counts

Google Search defines main content as any part of the webpage that directly helps the page achieve its purpose. The page then lists what that covers. Per the guidance, main content includes the primary text and media, interactive features such as calculators, tools, games and search, user-generated contributions such as reviews, comments and forums, tabbed or expanded sections such as specifications or safety notes, and page titles and headings.

The Search Engine Roundtable report quotes the sentence that places this in context: one of the most critical factors for assessing page quality is the quality of the main content. That sentence follows a reference to E-E-A-T, so Google is positioning main content quality as something alongside experience, expertise, authoritativeness and trustworthiness, not a replacement for them.

The practical reading is that "content" on a page is wider than the article body. A calculator that returns wrong numbers, a review block full of spam, or a tabbed specification section that hides the real information all fall inside Google's definition. So do the page title and headings, which means a misleading heading is a main content problem, not only a snippet problem.

The four attributes raters assess

The page says Search Quality raters are trained to evaluate four fundamental attributes of the main content. The table below sets out Google's description of each, taken from the page.

Two details are worth reading closely. First, effort is defined as including "the systems powering" the content, not only the writing. A tool, dataset or template that took real work to build counts. Second, accuracy is graded on a sliding scale: factual correctness for informational pages, a higher bar for YMYL topics such as health, money and safety.

The warning about fabricated creator profiles

In the part of the page about who created the content, Google now says to avoid using deceptive authorship information. It names the practice: 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. Google calls this a form of deception.

Search Engine Journal quotes Google as saying that any form of deception makes a page untrustworthy to both users and its automated quality systems, and is a signal of a low-quality page. That is the sentence that matters most for site owners, because it names automated systems and not only human raters.

The same report notes that the May 2025 rater guidelines already treated fake author profiles as lowest quality. What changed is where the statement sits. It used to be addressed to raters. It is now in the public documentation that site owners read. Search Engine Journal's comparison with the 8 June archive is the evidence that the paragraph is recent.

What the page says about disclosing AI use

The "How" section of the page asks questions for sites that use automation to substantially generate content. It asks whether the use of automation, including AI-generation, is self-evident to visitors through disclosures or other ways, whether the site provides background about how automation or AI-generation was used, and whether it explains why automation or AI was seen as useful.

The same section says that using automation, including AI-generation, to produce content for the primary purpose of manipulating search rankings violates Google's spam policies. The reports and page text read do not say whether these particular sentences are new in this edit, so this post does not claim they are. They are included because they sit on the same page and apply to the same question: what a site should be able to show about how its content was made.

Timeline of what is known

What Google and the reports did not say

• No ranking update, system name or rollout window was announced with the edit.
• The text does not say how many pages are affected or give any figure for fake author profiles.
• The page does not say that a byline improves rankings. It says deceptive authorship signals low quality.
• Nothing in the sources mentions Thailand or Thai-language content.
• The page describes what raters are trained to evaluate. The passages read do not describe how rater scores feed into automated ranking.

What this means for Thai marketers

The page is global and says nothing specific to Thailand, so the following is analysis, not a claim from Google. Thai sites that publish under invented author names, or that use AI-generated portraits for "expert" profiles, are doing exactly what the new paragraph describes. Where a Thai site publishes at volume in either language, the cheapest risk reduction is to make authorship real: a named person who exists, with credentials that can be checked, or a clearly labelled team or brand byline.

For agencies writing for clients, the practical effect is on process. A brief that asks for a quick "author box" with a stock face now carries a documented downside. A better brief asks who actually reviewed the piece and what they added.

Main content also gives a way to audit pages that rank poorly despite decent links. If a page's real value is a tool, a table or a set of reviews, check that those elements work and are accurate, because Google counts them as main content. Teams that already run a SEO audit can add a main content pass: list every element that directly serves the page's purpose and test each one.

Checklist for your own site

1. List every author profile and confirm the person exists, the photo is of that person, and any stated credentials are true.
2. Replace invented or AI-generated author identities with real people or an honest team byline.
3. For each key page, name its purpose and list the elements that serve it: text, media, tools, reviews, tabs, headings.
4. Test interactive features for correctness, and remove or moderate spam in user-generated sections.
5. Ask what human effort or original information each page contains that other sites lack.
6. For YMYL topics, check claims against expert consensus and keep a review record.
7. If you use automation to generate content, decide how you will disclose it and be ready to explain why it was used.

This work sits naturally within an SEO programme and in editorial standards for content marketing, where authorship and review rules are easiest to enforce at the point of production.

Frequently asked questions

Did Google announce a new algorithm update?

No, the reports describe a documentation edit and no ranking update was announced. The page shows a last-updated date of 1 October 2026 UTC, and neither Search Engine Roundtable nor Search Engine Journal cites a rollout date.

What is main content according to Google?

Main content is any part of the webpage that directly helps the page achieve its purpose. It includes primary text and media, interactive tools, user-generated contributions, tabbed or expanded sections, and page titles and headings.

Are AI-generated author photos a problem?

Google says fabricating creator profiles with AI-generated headshots, made-up names or false credentials is a form of deception. Search Engine Journal quotes Google as saying deception makes a page untrustworthy to both users and automated quality systems.

Do I have to disclose that I used AI?

The page does not state a blanket requirement. It asks sites that use automation to generate content substantially whether the use is self-evident to visitors, whether they explain how it was used, and why it was seen as useful.

Is this specific to Thailand?

No, none of the sources mention Thailand. The guidance applies to Search generally, and any Thailand-specific reading in this post is analysis and not a statement from Google.
