Reporting vocabulary

Impressions count appearances in eligible search surfaces; clicks count visits from those appearances; CTR is clicks divided by impressions. Index coverage describes discovery and indexing states. Manual actions are different from ordinary ranking fluctuations.

• Google AI search — Google’s May 2026 guidance says core SEO best practices remain relevant to AI Overviews and AI Mode, while unique, non-commodity content and crawlability matter more than creating endless query variants.
• Scaled content — Google defines scaled content abuse as generating many pages primarily to manipulate rankings when those pages add little or no user value, regardless of whether automation or AI created them.
• Structured data — Google’s structured-data guidelines require markup to represent the main visible content accurately; technically valid JSON-LD can still be ineligible when it is misleading or hidden.
• Image SEO — Google recommends relevant, high-quality images, descriptive filenames, useful alt text, and consistent image metadata; keyword-stuffed alt text is specifically discouraged.
• Title links — Google recommends a unique, descriptive and concise title element for every page and warns against unnecessarily verbose or repetitive titles.
• FAQ changes — Google deprecated FAQ rich results from May 7, 2026, so FAQs should be written for users first rather than treated as a guaranteed SERP enhancement.
• IndexNow — Bing’s IndexNow documentation says it can notify participating search engines about added, updated or deleted URLs, but submission does not guarantee crawling or indexing.
