Labs / Research index
Research you can inspect.
SEO Blitz Labs documents controlled tests of the analyzer, its scoring model, and its browser behavior. Each study separates measured output from interpretation.
01 / Evidence standard
Every result has a chain.
A published Lab claim must trace to retained input, the exact analyzer version, raw analyzer output, deterministic derived results, and a bounded interpretation. If a result cannot be reproduced from that chain, it does not belong in a published study.
Labs are not ranking experiments. They test the behavior SEO Blitz can observe and document what it cannot establish.

Research has limits.
These studies use controlled inputs and one shipped product version. They do not predict rankings, establish universal privacy guarantees, or replace human review. Each page states its environment, evidence, and limitations.
