<b>Page quality is judged on Main Content first, and most audits skip it</b>

The question: when raters score a page's quality, what part of the page are they looking at?

The QRG partitions every page into Main Content, Supplementary Content, and Advertisements, and is explicit that quality is judged primarily on the Main Content — the part that directly satisfies the page's purpose. Supplementary content (navigation, related links) and ads are evaluated for whether they <i>distract from or deceive</i> about the main content.

This ordering is frequently inverted in practice. Audits obsess over schema, internal links, and sidebar widgets — all supplementary — while the main content remains a lightly-reworded competitor summary. Per the guidelines, a beautiful page wrapper around weak main content earns a low rating; the wrapper cannot rescue it.

The guidelines also penalize a specific deceptive pattern: main content that is hard to find because ads or supplementary content are designed to be mistaken for it, or that pushes the real content below a wall of interstitials. For monetized affiliate layouts this is a direct hazard — if a rater cannot quickly distinguish your answer from your ad units, the page reads as deceptive.

Caveat: high-quality supplementary content does count positively, especially for navigation-heavy pages like store category pages. The point is sequence, not dismissal.

What we still don't know: how the systems operationalize the main-versus-supplementary boundary on layouts where the distinction is genuinely blurry, such as comparison tables that are simultaneously content and monetization.
