How to fix non iso date on Wix

Steps for Wix

1. Wix automatically generates structured data for Blog Posts and uses ISO-8601 dates internally — if you see a non-ISO date it is coming from a custom HTML embed or third-party app.
2. To check: in the Wix Editor, look for any HTML Embed elements (Add → Embed → Custom Code or Embed a Widget) that contain JSON-LD with date fields.
3. Click on the embed, open the code, and manually update any date values to YYYY-MM-DD format.
4. For site-wide custom code, go to Settings → Custom Code, find the relevant code block, and edit the date strings.
5. If you use a Wix app that injects schema (e.g., a blog or events app), check that app's settings panel for date format options.
6. Use Google's Rich Results Test on the live Wix page URL to confirm the corrected date is being read.

What is non iso date?

Structured data on your pages (the hidden JSON-LD code that tells Google and other search engines what your content is about) includes date fields such as `datePublished` and `dateModified`. ISO-8601 is the internationally standardised date format — for example, `2025-03-12` or `2025-03-12T09:00:00+00:00`. When a date is written in plain English instead — like "Wed Mar 12 2025" — machines can't reliably read it, because there's no single agreed way to parse natural-language dates. Your current schema contains at least one date in a non-standard format, which means search engines may misread or completely ignore it.

Content freshness is a real ranking signal. Google uses `datePublished` and `dateModified` to understand when your pages and articles were created or last updated, and it surfaces that information directly in search results (e.g., "3 days ago" next to a result). If the date can't be parsed, Google may either ignore freshness entirely — hurting rankings for time-sensitive queries — or infer an incorrect date, making a new page look old. For AEO (Answer Engine Optimisation), where AI-powered tools like Google's AI Overviews and Bing Copilot prioritise the freshest, most reliable sources, an unreadable date can mean your content is skipped over in favour of competitors whose schema is clean. Fixing this is a quick win with direct impact on how your pages are indexed and presented.
