I Ran a JSON-LD Audit on 25 Pages of My Own Sites. 21 Say They Were Modified Today.
I run five small launch sites, and each one has a /studio blog. Back in September I made myself an index of every post, and one line in it has bugged me since: "the on-page datePublished schema is a placeholder on most sites. Every Aura++ post says 2024-06-01, every IndieHunt post 2024-01-15, every MakerHunt post 2025-04-04, SideHunt outputs [object Object]." That's a nice hook for a post. So…
On November 8, 2026, a reporter ran a JSON-LD audit on 25 pages across five websites. The audit revealed that 21 pages had a dateModified attribute set to "today". The reporter noticed that some websites had placeholder dates for on-page datePublished schema, while others had real ISO timestamps. The audit script flagged common issues such as missing or unparseable dates, future dates, and incorrect dateModified values within 36 hours of the fetch.
The script, written in Node 18+, does not rely on any external dependencies and prints flags for the identified issues. The report emphasizes that structured data does not directly impact search rankings, but using it correctly can enable rich results.
