Ranking position alone no longer tells the full SEO story. AI Overviews, People Also Ask boxes, featured snippets, local packs, and knowledge panels now occupy the majority of above-the-fold real estate on Google. A page ranking #1 organically can still get zero clicks if an AI Overview answers the query directly. Search surface monitoring tracks all these SERP features for your keywords, not just your blue link position. We compared five APIs by their ability to detect and track the full spectrum of Google SERP features.
Scavio captures organic results, People Also Ask, featured snippets, and knowledge graph data in its SERP response, giving teams a starting point for search surface monitoring at $0.005/query.
