A marketer notices that one of their top blog posts has seen impressions increase in Google Search Console, but clicks have declined over the past two months. Using the AEO measurement pyramid, which layer should they investigate first?

The AEO measurement pyramid prioritizes investigation based on the observed issue. An increase in impressions but a decrease in clicks suggests a problem with how the content is presented or perceived, even if it's being seen. Layer two, AI visibility, focuses on how AI-powered search features (like answer engines, featured snippets, or People Also Ask boxes) are interacting with your content. If the page is being cited by answer engines, it might be providing a direct answer that satisfies the user's query without them needing to click through to the original source, thus increasing impressions but decreasing clicks. Layer one (search performance) is too basic; meta description length is a foundational element, but the issue here is more nuanced than just basic visibility. Layer three (business impact) is a consequence, not the root cause of the click decline. Declining clicks don't always indicate a content quality problem; sometimes, it's about how search engines are presenting the information.
