Google has added two new sections to its "creating helpful, reliable, people-first content" help document, expanding the guidance beyond E-E-A-T to define "main content" and to spell out four attributes that Search Quality raters use to judge it. The change landed the same day Google updated its AI-generated content document, marking a coordinated revision of its creator-facing quality guidance.

The most significant addition is a new statement elevating main content quality to a critical ranking-adjacent concern. Google wrote: "Beyond E-E-A-T, the Search Quality Evaluator Guidelines emphasize that one of the most critical factors for assessing page quality is the quality of the main content, specifically how effectively it allows the page to achieve its purpose and provide a satisfying user experience."

That wording matters. Google does not casually use the word "critical" in help documentation, and the new line effectively tells publishers that E-E-A-T alone does not complete the quality picture — the substance of the page itself must deliver on its stated purpose.

What counts as main content

For the first time in this document, Google defines "main content" as "any part of the webpage that directly helps the page achieve its purpose." The definition is broad and explicitly includes elements many site owners may not have considered part of their core content evaluation:

• Primary text and media: the main text, articles, images, audio, or video files on the page.
• Interactive features: built-in functionality such as calculators, online tools, games, or search functionality.
• User-generated contributions: forum discussions, customer reviews, comments, or user-uploaded media when they directly fulfill the page's purpose — for example, when the page exists to discuss a particular user question.
• Tabbed or expanded sections: information housed behind interactive tabs, such as product specifications, safety notes, or user reviews.
• Page titles and headings: the visible title and headings that summarize a page's topic and help users decide whether to visit.

The inclusion of tabbed content and user-generated contributions is notable for e-commerce and community-driven sites. Product specifications hidden behind tabs, or forum threads that constitute the page's reason for existing, now sit squarely inside the quality assessment zone rather than at its margins.

The four attributes raters evaluate

Google then describes how Search Quality raters review main content. "When reviewing content quality, Search Quality raters are trained to evaluate these fundamental attributes of the main content," the document states. The four attributes break down as follows.

Effort. Google measures "the extent to which human work went into creating the content or the systems powering it." Writing original analysis, manually translating a poem, or building a custom interactive map for a game represent high effort. Automatically generating pages from feeds, or using generative AI to produce large volumes of text without manual oversight or curation, represents little to no effort. Google adds a pointed clarification: attribution or giving credit to other sources does not replace the need for original effort.

Originality. Raters assess "the extent to which the content offers unique, original information or perspectives that aren't already available on other websites." This is a direct signal against re-aggregation and thin rewrites of material that already exists elsewhere.

Talent or skill. The content should demonstrate the ability needed to provide a satisfying visitor experience — clear writing, well-produced video, or functional page tools. Google tempers this with a practical note: not all content requires specialized expertise. Someone sharing a new method for clearing snow from their driveway generally does not need credentialed expertise for the page to be judged high quality.

Accuracy. Informational pages should be factually accurate. For topics that could significantly impact people's lives or well-being — YMYL topics — Google states the content "must be highly accurate and consistent with established expert consensus." Health, finance, and safety publishers face the strictest bar here.

Confirmed guidance versus ranking speculation

To be clear about what is confirmed: these are official additions to Google's help documentation, and they describe how human Search Quality raters are trained — not a direct description of ranking algorithm inputs. Google has long maintained that rater guidelines inform, but do not dictate, its automated systems. What the document signals, however, is how Google's quality framework is evolving: toward effort and originality as first-class criteria, and toward explicit scrutiny of mass-produced AI text without human curation.

The same-day update to the AI-generated content document reinforces that reading. Publishers relying on scaled generative output, feed-driven page generation, or unedited user contributions should expect those elements to count against quality assessments rather than neutrally fill space.

What to monitor

Watch for whether Google folds these four attributes — effort, originality, talent or skill, and accuracy — into future iterations of the Search Quality Evaluator Guidelines themselves, and whether upcoming core updates or spam policy enforcement begin reflecting the sharpened emphasis on human effort over scaled automation.
