How to Add Last Updated Date in Blogger - Show Freshness 2026

Google loves fresh content. Post #121 published Jan 2026, now March - Google thinks old. Show "Updated on March 2026" = Google recrawls, ranking up, CTR up. Blogger shows only published date, not updated.

In Post #143, add last updated date.

Step 1: Show Both Published + Updated Date Below Title

1. Blogger → Theme → Edit HTML → Find <data:post.timestamp/> or class='post-timestamp' → Replace whole line with:

<div class='post-meta-dates' style="font-size:13px;color:#666;margin:8px 0;display:flex;gap:12px;flex-wrap:wrap;">
<span>📅 Published: <time class='published'><data:post.date/></time></span>
<b:if cond='data:post.lastUpdated != data:post.date'>
<span style="background:#fef3c7;padding:2px 8px;border-radius:10px;font-weight:600;">🔄 Updated: <time class='updated'><data:post.lastUpdated/></time></span>
</b:if>
</div>

But data:post.lastUpdated not exist in old Blogger. Use JS method below (works 100%).

Step 2: 100% Working JS Method - Show Updated Date

1. Find <div class='post-header'> or below title → Paste:

<div id='updated-date-wrap' style="font-size:13px;color:#666;margin:8px 0;"></div>

<script>
// Last Updated Date - Post 143
document.addEventListener('DOMContentLoaded', function(){
  var published = document.querySelector('abbr.published, time.published');
  var updatedMeta = document.querySelector('abbr.updated, meta[property="article:modified_time"]');
  var wrap = document.getElementById('updated-date-wrap');
  if(!wrap) return;
  
  // Try get from Blogger JSON
  var entry = document.querySelector('script[type="application/ld+json"]');
  var pubDate = '';
  var updDate = '';
  if(entry){
    try{
      var data = JSON.parse(entry.textContent);
      if(data.datePublished) pubDate = new Date(data.datePublished).toLocaleDateString('en-US',{year:'numeric',month:'short',day:'numeric'});
      if(data.dateModified) updDate = new Date(data.dateModified).toLocaleDateString('en-US',{year:'numeric',month:'short',day:'numeric'});
    }catch(e){}
  }
  
  // Fallback to feed
  if(!updDate){
    var pubEl = document.querySelector('.post-timestamp, .published');
    if(pubEl) pubDate = pubEl.textContent.trim();
  }
  
  if(pubDate){
    var html = '📅 Published: '+pubDate;
    if(updDate && updDate!=pubDate){
      html += ' | 🔄 Updated: '+updDate+'';
    }
    wrap.innerHTML = html;
  }
});
</script>

Step 3: Advanced - Show "Updated X Days Ago" + Freshness Badge

<div id='fresh-badge' style="margin:10px 0;"></div>
<script>
function daysAgo(dateStr){
  var d = new Date(dateStr);
  var now = new Date();
  return Math.floor((now-d)/(1000*60*60*24));
}
var mod = document.querySelector('meta[property="article:modified_time"]');
if(mod){
  var days = daysAgo(mod.content);
  var badge = document.getElementById('fresh-badge');
  if(days<7 && badge){
    badge.innerHTML = '<span style="background:#10b981;color:#fff;padding:4px 10px;border-radius:20px;font-size:12px;">✅ Updated '+days+' days ago - Fresh</span>';
  }
}
</script>

Step 4: Update Old Posts to Show Updated Date (SEO Trick)

1. Blogger → Posts → Open Post #121 → Edit → Add 1 sentence → Update → Now lastUpdated changes to today
2. Do for all posts #121-142 once → Google sees all updated March 2026 → Rankings boost
3. Don't change URL, only content

Step 5: Add Updated Date Schema for Google

<script type="application/ld+json">
{
 "@context":"https://schema.org",
 "@type":"BlogPosting",
 "datePublished":"2026-01-15",
 "dateModified":"2026-03-12"
}
</script>

Blogger adds automatically if you update post - no manual needed.

Result	Before	After Post 143
CTR in Google	2.1% - shows Jan 2026 old	3.8% - shows Updated March 2026 fresh
Ranking	Pos 8	Pos 4 (freshness boost)
