Our Sitemap Had Been Frozen for 3 Weeks and Nobody Noticed

Our Sitemap Had Been Frozen for 3 Weeks and Nobody Noticed

We were doing a routine Search Console check when we froze. Looking at the sitemap report, we saw the last crawl date was 21 days ago. At first we thought "Google crawls slowly sometimes," but the real problem was something else entirely: we'd added over 2,400 new pages to the site since that date, yet Google was only seeing around 340 URLs. Three weeks of content hadn't even hit Google's radar.

How We Noticed: The Numbers Didn't Add Up

When we opened the "Sitemaps" section in Search Console, here's what we saw:

• Last crawled: November 3, 2024
• Discovered URLs: 342
• Actual reality: We had 2,700+ active pages on the site

We'd been publishing content consistently for three weeks. We were adding an average of 100-150 new pages daily. But in Google's eyes, our site was still stuck at its state from three weeks ago. Our first reaction was "maybe the sitemap file is corrupted," but when we opened sitemap.xml in a browser, everything looked fine. All the new URLs were there, the XML format was valid, the last-modified dates were current.

Diagnosis: Google Wasn't Re-Crawling the Sitemap

To understand the problem, we followed these steps:

1. We Checked the Sitemap File Itself

First we verified that the sitemap.xml file was actually up to date. We ran a quick command-line check:

curl -I https://aicompatible.com/sitemap.xml
# Last-Modified: Thu, 23 Nov 2024 14:32:11 GMT
# Content-Length: 487234

The file was current. The size was well within reasonable limits (far below the 50MB cap). The problem wasn't with the sitemap file.

2. We Examined Search Console Logs

When we looked at the "Crawl Stats" section in Search Console, we noticed something interesting: Google's bots were actively crawling the site, but they weren't touching sitemap.xml at all. The last sitemap crawl really was 21 days ago, and Google hadn't bothered to check the sitemap again since then.

3. We Checked robots.txt

Maybe we'd accidentally blocked the sitemap, so we looked at robots.txt:

User-agent: *
Allow: /
Sitemap: https://aicompatible.com/sitemap.xml

No issues there either. The sitemap was properly declared.

The Real Problem: Google's Sitemap Crawl Frequency

After digging deeper, we realized: Google crawls sitemaps at whatever frequency it wants, and that frequency is entirely up to Google's algorithm. For a newer site, this interval can be days or even weeks. Our site was relatively new, and Google hadn't yet decided "I should check this site frequently."

Here was the problem: While we were adding hundreds of pages daily, Google was dropping by once every three weeks saying "hmm, 340 pages." Meanwhile, the 2,400 pages we'd added were sitting there waiting to be indexed.

The Fix: Manual Sitemap Submission

The solution was simple but required manual intervention. We resubmitted the sitemap in Search Console:

1. Went to Search Console → Sitemaps section
2. Clicked the "Test" button next to the existing sitemap
3. Once the test passed, we deleted the sitemap and re-added it

Six hours after this, Google re-crawled the sitemap. The discovered URL count jumped from 342 to 2,718. The next day, our indexed page count increased by 640%.

Automated Solution: Search Console API

To avoid hitting this problem again, we built an automated notification system using the Search Console API:

from google.oauth2 import service_account
from googleapiclient.discovery import build

credentials = service_account.Credentials.from_service_account_file(
    'service-account.json',
    scopes=['https://www.googleapis.com/auth/webmasters']
)

service = build('searchconsole', 'v1', credentials=credentials)

request = service.sitemaps().submit(
    siteUrl='https://aicompatible.com/',
    feedpath='https://aicompatible.com/sitemap.xml'
)

response = request.execute()

Now we automatically notify Google about our sitemap every day. This has prompted Google to think "ah, this site is active, I should check it more frequently."

Why Is This So Hard to Notice?

The insidious thing about this problem: Everything looks like it's working. Your sitemap file is there, robots.txt is correct, no errors in Search Console. But if your content production rate exceeds Google's sitemap checking rate, you're silently falling behind.

Most site owners do this:

• Add the sitemap once and forget about it
• Think "Google will find it anyway"
• Check Search Console once a month (if they check that often)

For fast-growing sites like ours, that's not enough. If you're adding hundreds of pages daily, you need to actively notify Google rather than waiting for automatic discovery.

How to Check Your Own Site

To see if you're experiencing this problem:

1. Go to Search Console → Sitemaps
2. Look at the "Last read" date
3. Compare the "Discovered URLs" count to your site's actual page count
4. If there's a big gap and the last crawl is older than a week, you've got a problem

AICompatible.com's site crawler automatically detects issues like this. You can see whether your sitemap is current, when Google last crawled it, and how many of your URLs are being missed. After we hit this problem ourselves, we added a dedicated "Sitemap Health" check to our crawler.

Bottom line: Even if your sitemap contains everything it should, how often Google checks it is a separate issue. For fast-growing sites, active notification instead of passive waiting can multiply your indexing speed several times over.
