Search Signal Lab is an independent publication about search-data infrastructure: SERP APIs, AI-search monitoring, citation tracking and the engineering decisions behind them.
How we evaluate products
We focus on workload fit: data surfaces, output structure, geography, delivery model, developer experience, pricing mechanics and maintenance burden. We avoid claiming firsthand testing unless a page explicitly documents a reproducible test.
