Verify that target keywords actually appear in a rendered page. Every term tied at the highest search volume must appear at least primary_min_hits times; every other term at least once. Matching is literal and case-insensitive: whitespace is never normalised, because 'web hosting' and 'webhosting' are different terms with different search volumes.

Compare a translation against its source document for structural drift: heading sequence, HTML tag sequence, table row count, internal link paths, price tokens, locale prefix on internal links, leftover source-script characters, introduced em dashes and emoji. This checks structure, not meaning: it cannot tell you a translation is good, only that it is no longer the same document.

Check that a content page links to at least one commercial page from its body, and optionally that it states a concrete figure. Links inside excluded boilerplate do not count, because a site-wide call-to-action block would otherwise satisfy this on every page and the check would guard nothing.

Scan copy for affirmative performance claims of the kind that get finance, gambling and health advertising rejected: guaranteed profit, stated win rates, promised returns. Sentences that exist to disclaim or prohibit those phrases are not flagged.

Decide a sitemap lastmod date honestly. Hash the meaningful content of a page, compare it against the stored hash, and move the date only when the content genuinely changed. Stamping today's date on every URL every build teaches crawlers that the field carries no information.

Hash the meaningful content of a page, with volatile blocks and scripts removed. Use it to tell a real edit from a rebuild.
