1 URL, 1 scan, no save, no email.
JSON-LD collision watcher
Two plugins. One page. Two Organizations.
Paste a public URL. GraphClash fetches the HTML, extracts every application/ld+json block, flattens @graph, and shows whether Yoast, Rank Math, a theme, or WooCommerce are emitting competing schema.
How it works
01
Paste a public URL
No account. We fetch that page’s HTML.
02
Read JSON-LD only
Every application/ld+json block. Not microdata.
03
Show competing @id
Same @type, different identifier, with a best-guess emitter.
Pricing
Solo $49
1 site, weekly recheck, email if a new collision appears or clears.
Studio $99
10 sites.
7-day card-required trial, then the monthly charge. No annual plan.
Common fights
- Which plugin
Rendered JSON-LD, then attribute each block.
- Yoast vs Rank Math
Two Organization nodes on one homepage.
- JSON-LD collision
Same @type, different @id, two emitters.
- WooCommerce Product
Woo Product plus a plugin or theme Product.
- After a plugin update
@id added, renamed, or a type turned back on.
- Theme vs plugin
Theme JSON-LD next to Yoast or Rank Math.
What this is not
GraphClash is not a Google penalty checker and not a schema generator. Google’s Rich Results Test checks supported rich-result markup. We surface repeated declarations and conflicting values for the same entity to review.
