From solo founders auditing their own sites to engineering teams protecting enterprise catalogs — here's how teams use SchemaCheck.
“Our product team kept removing the offers block from product descriptions to 'clean up' the page. SchemaCheck in CI blocked those PRs automatically — we recovered 18% of our Google Shopping impressions within two weeks.”

“We run SchemaCheck against our sitemap every night. It caught a Yoast update that silently removed datePublished from 3,000 article pages before Google noticed.”

“A Yoast plugin update removed the datePublished field from our Article schema across 4,000 posts. Our publish hook caught it on the first post — we fixed the config before the rest of the site was affected.”
