A plain-language explanation
SEOquake is a browser extension that presents basic technical data and SEO metrics for visited pages and search results.
Where it helps in practice
The extension quickly exposes page and result metrics but mixes technical facts with provider scores based on different methods.
The decision before implementation
Use it as a prompt for investigation rather than an automatic verdict on site quality.
How to verify the result
Confirm directives in source and compare third-party scores only within the same tool and period.
