clutterScore, scamness, unauthoritativeScore: Three Quality Demotions

01Three demotions in one system

System 15 combines three distinct quality demotions. clutterScore measures layout overload: too many ads, pop-ups, and distracting elements that disrupt the information flow. scamness measures fraud proximity: patterns that resemble known scams or deceptive practices. unauthoritativeScore flags content that lacks the E-E-A-T signals expected for its topic category.

Each demotion operates independently but feeds into the same Trust signal (T: primary). A page can trigger one, two, or all three demotions. The combined effect is multiplicative, not additive: a page with high clutter AND high scamness AND low authority receives a much heavier penalty than the sum of the individual penalties.

The three signals represent different kinds of trust violation. Clutter violates the user's attention: a page that buries content under ads is not trustworthy. Scamness violates the user's safety: a page that resembles known scams is dangerous. Unauthoritativeness violates the user's expectations: a page that claims expertise without demonstrating it is misleading.

02clutterScore: layout overload

clutterScore measures how much the layout interferes with content consumption. A page with one banner ad and clean text has a low clutter score. A page with five ads, two pop-ups, a sticky header, and interstitials has a high clutter score. The content is there, but the user has to fight through clutter to find it.

The Google API leak confirmed a clutterScore field. The field measures layout quality directly, not content quality. A page can have excellent content and still receive a high clutterScore if the layout is overloaded with ads and distractions.

clutterScore also has an indirect Authority signal (A: indirect). This makes sense: a cluttered page signals a publisher that puts ad revenue ahead of user experience, which undermines authority. A clean, focused page signals a publisher that values the reader's attention.

03scamness: fraud proximity

scamness measures how closely a page resembles known scam patterns. It does not ask whether the page IS a scam, but whether it shares characteristics with pages that have been identified as scams. A page that uses high-pressure sales tactics, fake countdown timers, or misleading testimonials will have a high scamness score even if the product is legitimate.

The scamness signal is particularly important for YMYL (Your Money Your Life) pages. Financial advice pages, medical information pages, and e-commerce pages face stricter scamness scrutiny because the potential harm from scams in these categories is greater.

scamness is also fed by contentEffort (System 9), the effort signal. A page that required significant editorial effort is less likely to be a scam. Scammers typically produce low-effort content: copy-paste templates, generated text, and recycled images. The link between scamness and contentEffort creates a two-signal defense: effort and pattern recognition.

04unauthoritativeScore: E-E-A-T deficit

unauthoritativeScore flags content that lacks the E-E-A-T signals expected for its topic. A medical article without author credentials, a financial page without disclaimer, or a legal guide without attorney attribution will receive a high unauthoritativeScore. The content may be accurate, but it doesn't demonstrate authority.

This is the connection to IS-Calibration (System 12). Raters are trained to evaluate E-E-A-T: does the page demonstrate expertise, authoritativeness, and trustworthiness? unauthoritativeScore learns to predict what a rater would say. If the rater would say 'this page doesn't demonstrate authority,' the model assigns a high score.

The key distinction: unauthoritativeScore is not about whether the content is wrong. It is about whether the content demonstrates the E-E-A-T signals that Google's raters look for. A factually correct page without author attribution may still receive a high unauthoritativeScore because it doesn't signal expertise.

05Implications for SEO practitioners

The three demotions create a comprehensive quality floor. A page must pass all three checks: not cluttered, not scammy, and authoritative. Failing any one demotion is recoverable. Failing all three is a strong negative signal.

For ad-heavy sites, clutterScore is the primary risk. The solution is not to remove all ads, but to make sure ads don't interfere with content consumption. Dismissible interstitials, ads clearly separated from content, and a clean mobile layout all reduce clutterScore.

For YMYL content, unauthoritativeScore is the primary risk. The solution is to add E-E-A-T signals: author bylines with credentials, editorial policies, fact-checking notes, and expert review badges. These are not decorative. They are signals that the quality model evaluates.

For any content, scamness is a risk if the page uses patterns associated with scams. High-pressure language, fake urgency ('Only 3 left!'), and testimonials that look manufactured all increase scamness. Removing these patterns is both good UX and good SEO.
