An accidental noindex on a key landing page silently removes it from search results; audit every page's robots directive to avoid invisible ranking losses.
<meta name="robots" content="..."> in <head> to control indexing per-pagenoindex only on pages that should not appear in search resultsnoindex, nofollow on pages you want crawled for PageRank flowgooglebot, bingbot) override the generic robots tag for that crawlerInspect <head> for <meta name="robots" content="...">. Verify the content value is intentional (e.g., production pages should not have noindex). Check for conflicting googlebot-specific tags.
Remove or update the noindex directive from pages that should appear in search results. For pages that must be blocked, confirm noindex is intentional. Remove duplicate or conflicting robots meta tags.
Explain the difference between robots.txt and meta robots, when each should be used, and why noindex combined with follow still allows link equity to flow.
Review metadata generation, rendered HTML, structured data, and response headers related to Set robots meta directives correctly. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted. The headline lift of +9 percentage points is the difference between those two pass rates over the 23 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
