Structured data is code (JSON-LD) that tells search engines what is on a page, such as a product, an article or a company. On this page a block cannot be read because the code is broken.
A broken block is ignored completely. You lose rich results in Google, and AI tools miss the facts you meant to give them.
Snaglist reads every JSON-LD block on every page and lists the pages with blocks that cannot be parsed, with the number of broken blocks.
Snaglist runs this check and 43 others on every page of your site, every week. 14 days free, no credit card needed.
