Show published and updated dates

Google uses publication and modification dates to assess content freshness, which influences rankings for time-sensitive queries. Visible dates also build user trust by signalling that content is current and maintained.

Quick Reference

  • Include a visible published date and a dateModified in JSON-LD for every article or blog post
  • Use ISO 8601 format (2024-03-15T10:00:00Z) in structured data; human-readable in the visible UI
  • Update dateModified only when content meaningfully changes — not on trivial edits

Check

On each article or blog page, check: (1) Is there a visible published date in the page body or byline? (2) Does the JSON-LD Article or BlogPosting block include datePublished and dateModified properties in ISO 8601 format? (3) Does the <head> include <meta property="article:published_time"> and <meta property="article:modified_time"> Open Graph tags?

Fix

  1. Add a visible publication date in the page byline: <time datetime="2024-03-15">March 15, 2024</time>.
  2. Add datePublished and dateModified to the Article JSON-LD block: 
    {
  "@type": "Article",
  "datePublished": "2024-03-15T10:00:00Z",
  "dateModified": "2024-11-20T14:30:00Z"
}
  3. Add Open Graph article time tags to <head>: 
    <meta property="article:published_time" content="2024-03-15T10:00:00Z">
<meta property="article:modified_time" content="2024-11-20T14:30:00Z">
  4. Ensure your CMS or build system updates dateModified automatically on content saves.

Explain

Google's freshness algorithm rewards recently published or updated content for time-sensitive queries. Structured date markup lets Google confidently surface the correct date in search snippets; without it, Google must guess from page text or HTTP headers, often producing wrong or missing dates.

Code Review

Verify that Article or BlogPosting JSON-LD includes both datePublished and dateModified in ISO 8601 format. Check that <time datetime='...'> elements in the body use machine-readable dates. Confirm dateModified updates when content changes, not just on every deploy.
