Reveals structured metadata (Microdata, RDFa, JSON-LD, Turtle, etc.) embedded within HTML documents.
The OpenLink Structured Data Sniffer (OSDS) is a browser extension for Google Chrome, Mozilla Firefox, and Opera (with builds planned for Apple Safari, and Microsoft Edge) that unveils metadata oriented structured data embedded within HTML documents.
At its core, every search engine optimization (SEO) effort requires agility in managing document metadata.
OSDS provides a productive way to check the impact of such document metadata on the results pages of various search engines.
