Our Sitemap Froze for 3 Weeks and Google Missed 2,400 New Pages
Our Sitemap Had Been Frozen for 3 Weeks and Nobody Noticed
We were doing a routine Search Console check when we froze in our tracks. Looking at the sitemap report, the last crawl date showed 21 days ago. At first we thought "maybe Google's just been slow to crawl," but here's what really shocked us: during those 3 weeks, we'd added over 2,400 new pages to our site, yet the URL count Google was seeing was still stuck at the number from 3 weeks prior.
In other words, Google had no idea thousands of our new pages even existed.
How We Discovered the Problem: A Lucky Check
Honestly, we stumbled onto this completely by accident. We normally check Search Console weekly, but we don't always dive into the sitemap report. That day, while checking the "Page Indexing" report to see how a new content series was performing, we noticed something odd: most pages published in the last 2 weeks were stuck in "Discovered - currently not indexed" status.
That sent us to the sitemap report. When we clicked through to our sitemap URL, here's what we saw:
- Last read: 21 days ago
- Discovered URLs: 1,847
- Actual URLs in sitemap: 4,200+
Our sitemap was updating, the new URLs were in there, but Google hadn't read it in 3 weeks. It was like the whole thing had just... frozen.
Diagnosis: Where Was the Problem?
First, we checked the sitemap file itself. Opening sitemap.xml in a browser, it looked fine—new URLs were there, XML format was valid. We ran it through an XML validator. No errors.
Then we checked our server logs. Googlebot hadn't requested the sitemap once in the past 3 weeks. So the problem wasn't on our end—it was in Google's crawling behavior.
When we checked the sitemap status in Search Console, there were no error messages. Just an old date and an old URL count. Google had simply "forgotten" to read our sitemap again.
After some research, we learned this is a rare but known issue. Sometimes something goes wrong in Google's sitemap crawl queue and certain sitemaps get "stuck"—Google just stops scheduling them for recrawl.
The Fix: Manual Intervention Required
Normally sitemaps should be crawled automatically, but in this case we had to intervene manually. We took a two-step approach:
1. Resubmitted the Sitemap in Search Console
We removed and re-added the sitemap in the Search Console interface. But that wasn't enough—Google didn't immediately crawl it. At this point we moved to a more aggressive method.
2. Forced Update via Search Console API
Google's Search Console API has a sitemap "resubmit" feature. We used it to programmatically resubmit the sitemap:
POST https://www.googleapis.com/webmasters/v3/sites/{siteUrl}/sitemaps/{feedpath}
About 6 hours after doing this, Google recrawled our sitemap. The next day we saw the new URLs being discovered in Search Console. Within 48 hours, most of our new pages were indexed.
Why Is This So Hard to Detect?
The insidious thing about this problem is how silently it happens. You don't get any error messages. Your site works, your sitemap file is fine, but Google just stops reading it.
For most site owners, this problem stays invisible because:
- Old pages are already indexed: Since most of your site is already in Google, you don't immediately notice a traffic drop
- New content is added gradually: If you're adding 1-2 pages per day, their absence from the index doesn't stand out
- You don't check Search Console regularly: Most people only look at Search Console when something's already wrong
- Internal links partially compensate: Google can still discover new pages through internal links, but this is much slower
In our case, the problem became obvious because we were adding so many pages in a short time. But for a site publishing at a normal pace, this issue could go unnoticed for months.
What Site Owners Should Do
After this experience, we realized how critical it is to regularly monitor sitemap health. Our recommendations:
- Check your sitemap report weekly: Look at the last crawl date and discovered URL count
- Know your sitemap's URL count: Compare what Search Console sees versus what's actually there
- Follow up after publishing new content: Check if it's getting indexed within 3-5 days
- Set up monitoring: Build an automated system that tracks your sitemap's last crawl date
Automated Detection: A Better Way
After this incident, we added a sitemap health check feature to AICompatible.com's crawler. The system now automatically:
- Counts the URLs in your sitemap file
- Pulls the last crawl date and Google's URL count from the Search Console API
- Detects major discrepancies or extended freeze periods
- Alerts the site owner
Because these kinds of technical issues, when they go unnoticed, silently erode your growth potential. Your new content isn't reaching Google, your competitors are passing you, and you don't even know it's happening.
When was your sitemap last crawled? We recommend checking.
