Decoded: Google Helpful Content Guidelines

Since Google's Search Quality Evaluator Guidelines themselves were leaked way back in 2014, I and others like Cyrus Shepard, Marie Haynes, Jennifer Slegg, and Lily Ray have worked to highlight the true significance of the Search Quality Evaluator Guidelines (SQEG)—and this article aims to finally prove that significance.

Building on the comprehensive analysis of quality content in my previous article and the proof that the 2024 Content Warehouse leak provided the definitive blueprints (forensically validated by experts like Mike King and Rand Fishkin, and further analyzed by Mark Williams-Cook) — this work applies my Creative Inference Optimisation methodology to the Search Essentials guidance.

This approach aims to establish a new "canon of truth" by linking the official guidelines directly to the code.

Here's Google's Helpful content guidelines mapped to the Google content warehouse leak attributes and DOJ trial disclosures.

Creating Helpful, Reliable, People-First Content (Re-Engineered)

Google's automated ranking systems are designed to prioritize helpful, reliable information [Q*, siteAuthority, predictedDefaultNsr], that's created to benefit people [P*], and not content that's created to manipulate search engine rankings [SpamBrain, DocLevelSpamScore, spamrank].

Self-Assess Your Content

Also consider an audit of the drops you may have experienced. Look closely at these to understand how they're assessed against some of the questions outlined here.

Content and Quality Questions

• Does the content provide original information, reporting, research, or analysis? [OriginalContentScore, contentEffort]
• Does the content provide a substantial, complete, or comprehensive description of the topic? [contentEffort, bodyWordsToTokensRatio, QBST]
• Does the content provide insightful analysis or interesting information that is beyond the obvious?
• If the content draws on other sources, does it avoid simply copying or rewriting those sources, and instead provide substantial additional value and originality? [shingleInfo, OriginalContentScore, copycatScore]
• Does the main heading or page title provide a descriptive, helpful summary of the content? [titlematchScore, goldminePageScore]
• Does the main heading or page title avoid exaggerating or being shocking in nature? [BadTitleInfo, serpDemotion]
• Is this the sort of page you'd want to bookmark, share with a friend, or recommend? [goodClicks, socialgraphNodeNameFp]
• Does the content provide substantial value when compared to other pages in search results? [predictedDefaultNsr, QualityBoost]
• Does the content have any spelling or stylistic issues? Is the content produced well, or does it appear sloppy or hastily produced? [lowQuality, gibberishScores]
• Is the content mass-produced by or outsourced to a large number of creators, or spread across a large network of sites? [numOfUrlsByPeriods, fireflySiteSignal]

Expertise Questions

• Does the content present information in a way that makes you want to trust it, such as clear sourcing, evidence of the expertise involved, background about the author or the site that publishes it? [siteAuthority, authorObfuscatedGaiaStr, isAuthor, spamrank]
• If someone researched the site producing the content, would they come away with an impression that it is well-trusted or widely-recognized as an authority on its topic? [siteAuthority, predictedDefaultNsr]
• Is this content written or reviewed by an expert or enthusiast who demonstrably knows the topic well? [authorReputationScore, siteFocusScore]
• Does the content have any easily-verified factual errors? [consensus_score, is_debunking_query]

Provide a Great Page Experience

Google's core ranking systems look to reward content that provides a good page experience [IndexingMobileVoltVoltPerDocData].

Site owners seeking to be successful with our systems should check if you're providing an overall great page experience across many aspects [mobileCwv, inp, cls].

Focus on People-First Content

• Do you have an existing or intended audience for your business or site that would find the content useful if they came directly to you? [queriesForWhichOfficial, smallPersonalSite, brickAndMortarStrength]
• Does your content clearly demonstrate first-hand expertise and a depth of knowledge? [contentEffort, productReviewPUhqPage]
• Does your site have a primary purpose or focus? [siteFocusScore, siteRadius]
• Will someone leave feeling they've learned enough about a topic to help achieve their goal? [lastLongestClicks]
• Will someone reading your content leave feeling like they've had a satisfying experience? [NavBoost, goodClicks]

Avoid Creating Search Engine-First Content

• Is the content primarily made to attract visits from search engines? [spamrank, lowQuality]
• Are you producing lots of content on many different topics? [numOfUrlsByPeriods]
• Are you using extensive automation to produce content on many topics? [contentEffort (low), gibberishScores]
• Are you mainly summarizing what others have to say without adding much value? [OriginalContentScore (low), contentEffort (low)]
• Are you writing about things simply because they seem trending and not because you'd write about them otherwise? [siteRadius (high)]
• Does your content leave readers feeling like they need to search again to get better information from other sources? (pogo-sticking) [badClicks, serpDemotion]
• Are you changing the date of pages to make them seem fresh when the content has not substantially changed? [lastSignificantUpdate (checked against bylineDate)]
• Your Money or Your Life topics, or YMYL for short [ymylHealthScore, ymylNewsScore].

Get to Know E-E-A-T and the Quality Rater Guidelines

Google's automated systems are designed to use many different factors to rank great content. After identifying relevant content, our systems aim to prioritize those that seem most helpful. To do this, they identify a mix of factors that can help determine which content demonstrates aspects of experience, expertise, authoritativeness, and trustworthiness (E-E-A-T) [Q*, siteAuthority, predictedDefaultNsr].

Of these aspects, trust (Q*) is most important.

As confirmed in the DOJ trial, engineer HJ Kim testified that "Q (page quality, i.e., the notion of trustworthiness) is incredibly important"*. The others contribute to trust, but content doesn't necessarily have to demonstrate all of them.

While E-E-A-T itself isn't a specific ranking factor, using a mix of factors that can identify content with good E-E-A-T is useful. For example, our systems give even more weight to content that aligns with strong E-E-A-T for topics that could significantly impact the health, financial stability, or safety of people, or the welfare or well-being of society. We call these "Your Money or Your Life" topics, or YMYL for short [ymylHealthScore, ymylNewsScore].

Search quality raters are people who give us insights on if our algorithms seem to be providing good results, a way to help confirm our changes are working well. In particular, raters are trained to understand if content has strong E-E-A-T. The criteria they use to do this is outlined in our search quality rater guidelines.

Search raters have no control over how pages rank. Rater data is not used directly in our ranking algorithms. Rather, we use them as a restaurant might get feedback cards from diners. The feedback helps us know if our systems seem to be working.

Reading the guidelines may help you self-assess how your content is doing from an E-E-A-T perspective, and help align it conceptually with the different signals that our automated systems use to rank content.

Ask "Who, How, and Why" About Your Content

Consider evaluating your content in terms of "Who, How, and Why" as a way to stay on course with what our systems seek to reward.

Who (Created the Content)

Something that helps people intuitively understand the E-E-A-T of content is when it's clear who created it. That's the "Who" to consider.

• Is it self-evident to your visitors who authored your content?
• Do pages carry a byline, where one might be expected?
• Do bylines lead to further information about the author or authors involved, giving background about them and the areas they write about?

If you're clearly indicating who created the content, you're likely aligned with the concepts of E-E-A-T. We strongly encourage adding accurate authorship information [isAuthor, authorObfuscatedGaiaStr, authorReputationScore].

How (The Content Was Created)

It's helpful to readers to know how a piece of content was produced: this is the "How" to consider including in your content.

For example, with product reviews, it can build trust with readers when they understand the number of products that were tested, what the test results were, and how the tests were conducted, all accompanied by evidence of the work involved, such as photographs [productReviewPUhqPage, productReviewPPromotePage, original_media_score, docImages].

Many types of content may have a "How" component to them. That can include automated, AI-generated, and AI-assisted content. Sharing details about the processes involved can help readers and visitors better understand any unique and useful role automation may have served.

• Is the use of automation, including AI-generation, self-evident to visitors through disclosures or in other ways?
• Are you providing background about how automation or AI-generation was used to create content?
• Are you explaining why automation or AI was seen as useful to produce content?

Overall, AI or automation disclosures are useful for content where someone might think "How was this created?".

Why (Was the Content Created)

"Why" is perhaps the most important question to answer about your content. Why is it being created in the first place?

The "why" should be that you're creating content primarily to help people [lastLongestClicks, goodClicks], content that is useful to visitors if they come to your site directly.

If the "why" is that you're primarily making content to attract search engine visits, that's not aligned with what our systems seek to reward. If you use automation, including AI-generation, to produce content for the primary purpose of manipulating search rankings, that's a violation of our spam policies [SpamBrain, DocLevelSpamScore].

Disclaimer: The Necessity of "Creative Inference Optimisation"

Why this logical inference is required:

This analysis utilises a methodology defined by the author as "Creative Inference Optimisation". This approach is necessary because:

1. The Missing Instruction Manual

The Google Content Warehouse leak provided the "blueprints" (the raw code and attributes) but not the operating manual.

We have the variable names (e.g., contentEffort), but Google does not explicitly state, "This variable is used to measure E-E-A-T." nor does it give us the "Weights and curves".

2. Bridging the Gap

There is a distinct gap between Google's public-facing advice (the Search Quality Evaluator Guidelines) and its internal engineering reality.

Logical inference is the only tool available to bridge this gap by mapping the human concepts (like "Effort") to their likely machine-readable counterparts (like [contentEffort]).

Furthermore, the public record confirms that the leak did not include specifics on the "curves and thresholds" (a key phrase referenced in the DOJ vs. Google antitrust litigation) that determine how factors are weighted, necessitating expert interpretation.

3. Evidence-Based Interpretation

While the documents are authentic, the specific connections drawn here (e.g., linking siteAuthority to Q*) represent the author's "expert interpretation" and "logical inference".

This method moves the industry from pure guesswork to an "evidence-based framework".

A Final Note

This work is intended to demystify the search engine's operations, fundamentally transforming the black box into a blueprint for understanding.

I, as special advisor to Searchable.com, am working to demystify Google Search, transforming the black box into a blueprint for you to understand. I’m using this primary research to help build the next generation SEO tool.

I encourage you to embrace critical thinking in all your SEO analysis. The foundation for this entire discussion lies within that corpus of documents. If you have the drive to prove or refine these inferences, the material is there for you to explore for yourself.

This analysis represents a methodology I call Creative Inference Optimisation. It bridges the gap between the 'product specification' found in Google's human-focused Search Quality Evaluator Guidelines and the 'engineering blueprints' exposed by the Content Warehouse API leak. The result is a single, evidence-based framework for modern SEO.

I welcome feedback or edits to all my works, so please get in touch. This is my art. I hope you enjoyed it.
