SERP is the page a search engine returns for a query. The acronym is older than Google — but the layout it describes has changed beyond recognition in the last two years.
The modern Google SERP for a typical informational query is layered:
- AI Overview at the very top (when Google decides to generate one) — a synthesized answer with citations
- People Also Ask — expandable Q&A boxes
- Featured snippet — pulled-quote from one source
- Sitelinks / Knowledge Panel for brand queries
- Ten organic results — the historical blue-link list
- Related searches at the bottom
Each layer is its own competition. Ranking #1 in the organic list means roughly nothing if an AI Overview owns the top of the fold.
Why it matters for AEO
The AEO half of SERP — AI Overviews, featured snippets, People Also Ask — is increasingly where attention goes. Citation in the AI Overview is the most valuable single placement because it gets read before any blue link.
The same pages don't always win both. A page can rank #1 organically and never appear in the AI Overview, or vice versa. The signals overlap but aren't identical: organic ranks reward link equity and SEO mechanics; AI citation rewards EEAT signals, structured extractability, and crisp factual phrasing.
What b/cited does about it
- Organic side — cluster + ownership analysis uses Search Console data, which reflects organic SERP positions
- AI Overview side — the AEO citation tracker re-runs your top SERP queries against ChatGPT, Claude, and Perplexity to detect whether AI surfaces cite you
Together they answer "how do I appear on the SERP, end to end" instead of just "where do I rank organically."
