**The Sitemaps report shows which sitemaps Google knows about for your property, whether it could read them and how many URLs it discovered.** Combined with Page indexing, split sitemaps are the easiest way to see which kind of content Google indexes and which it doesn't.

*Checked 4 November 2026 (CET) against Search Console Help and Google Search Central documentation. Search Console reports and rollouts change often, and some features only appear for eligible properties, so confirm in your own property. "Our view" marks MentionX opinion. Ledgerline is a fictional company used for illustration.*

> **Key takeaways**
>
> - Owners can submit sitemaps in the report; anyone can reference one in robots.txt.
> - Statuses are Success, Couldn't fetch, and Sitemap had X errors.
> - One sitemap can hold 50,000 URLs or 50MB uncompressed. Use a sitemap index for more.
> - A sitemap helps discovery but doesn't guarantee indexing.
> - Split sitemaps by content type to diagnose indexing by section.

## What does the report show?

From Google's [Sitemaps report help](https://support.google.com/webmasters/answer/7451001):

| Column | Meaning |
|---|---|
| Sitemap | The URL, relative to the property |
| Type | Sitemap or sitemap index |
| Submitted | When you submitted it |
| Last read | When Google last processed it |
| Status | Success, Couldn't fetch, Sitemap had X errors |
| Discovered pages / videos | URLs found in the sitemap |

## Do you need a sitemap?

Google's [sitemap guidance](https://developers.google.com/search/docs/crawling-indexing/sitemaps/build-sitemap) says small sites of about 500 pages or fewer, well linked internally, may not need one. Most marketing sites benefit anyway: new pages are found faster, and split sitemaps make indexing diagnosis much easier.

## How do split sitemaps help marketers?

| Sitemap | Contains | What it tells you |
|---|---|---|
| sitemap-products.xml | Product and pricing pages | Are money pages indexed? |
| sitemap-blog.xml | Articles | Is content being indexed as fast as you publish? |
| sitemap-glossary.xml | Definitions | Are thin pages being skipped? |
| sitemap-key.xml | Top 50 pages | Your weekly health check |

Then filter Page indexing by each sitemap to compare indexing rates.

*Our view:* the key-pages sitemap is the single most useful thing a marketer can ask a developer to set up for Search Console.

> **Pro move:** if your CMS can't split sitemaps, you can still submit a hand-made key-pages sitemap. It only needs to be valid XML on your domain.

## Troubleshooting sitemap statuses

| Status or symptom | Likely cause | Fix |
|---|---|---|
| Couldn't fetch | Wrong URL, blocked by robots.txt, server error, or auth required | Open the sitemap URL in a private browser window; check robots.txt |
| Sitemap had X errors | Invalid XML, wrong namespace, URLs on another host | Open the details, fix the generator, resubmit |
| Success but few pages indexed | Sitemap lists URLs Google chooses not to index | Check Page indexing filtered to that sitemap |
| Discovered pages count is far lower than expected | Sitemap is truncated or out of date | Check your CMS sitemap settings |
| Old sitemap still listed | Removed from the report but still referenced in robots.txt | Remove the robots.txt reference too |
| Sitemap over limits | More than 50MB uncompressed or 50,000 URLs | Split and use a sitemap index |

## Sitemap hygiene checklist

- Only canonical, indexable URLs that return 200.
- No noindexed, redirected or parameter URLs.
- Accurate `lastmod` dates that change only when content changes.
- One sitemap per content type (products, blog, help) for easier diagnosis.
- Referenced in robots.txt with a `Sitemap:` line.

## Building a key-pages sitemap

A key-pages sitemap is a normal XML sitemap that lists only your most important URLs. It's for diagnosis, not to replace your full sitemaps.

```xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url><loc>https://www.ledgerline.example/</loc></url>
  <url><loc>https://www.ledgerline.example/pricing/</loc></url>
  <url><loc>https://www.ledgerline.example/product/invoice-approval/</loc></url>
</urlset>
```

1. List 30-100 URLs: home, pricing, product pages, top converting content.
2. Use the exact canonical form (protocol, www or not, trailing slash).
3. Upload it to your site, for example `/sitemap-key.xml`.
4. Submit it in the Sitemaps report.
5. Use it as the filter in Page indexing every week.

Review the list each quarter as priorities change.

## Sitemap index files

Large sites use a sitemap index file that lists other sitemaps. Submit the index once; the report shows each child sitemap. This makes it easy to add content-type sitemaps without resubmitting.

## Edge cases

- **Sitemaps on another host.** A sitemap must list URLs from the same property unless you've verified both. CDN-hosted sitemaps often break this.
- **`lastmod` set to today on every URL.** Some CMSs do this. It makes the date useless as a signal; ask for real modification dates.
- **Removed sitemaps.** Removing a sitemap from the report doesn't stop Google knowing the URLs, and if robots.txt still references it Google may keep reading it.
- **Video and image sitemaps.** These extensions help Google find media; check your CMS before building them by hand.
- **Non-owners.** Full users can view the report but can't submit. Add a `Sitemap:` line to robots.txt instead.

## A diagnostic hack

When a content type has a low indexing rate, create a temporary sitemap of 50 URLs from that type that you think are strong. If those index well and the rest don't, the problem is quality or duplication in the weaker pages, not a technical block.

## Questions practitioners ask

**Should the sitemap include paginated or tag pages?** Only if you want them indexed. Most marketing sites leave tag pages out.

**Do I need `priority` and `changefreq`?** Google ignores them. Accurate `lastmod` is what matters.

**Can I submit a sitemap for a subdomain from a Domain property?** Yes; a Domain property covers its subdomains.

**How do I know Google re-read my sitemap?** Check the Last read date in the report.

## Ledgerline walkthrough: fixing a "Couldn't fetch"

After a CDN change, the blog sitemap showed Couldn't fetch. The developer found the CDN was returning a bot challenge page to Googlebot. They added an exception for the sitemap path, the SEO lead resubmitted, and the status returned to Success after Google re-read it.

## Sitemap size limits and index files

Google's sitemap documentation sets a limit of 50,000 URLs or 50 MB uncompressed per sitemap file. Larger sites split URLs across several files and list them in a sitemap index file, which you submit once. Splitting by section also makes the Page indexing sitemap filter more useful, even on small sites.

```xml
<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap><loc>https://www.example.com/sitemap-product.xml</loc></sitemap>
  <sitemap><loc>https://www.example.com/sitemap-blog.xml</loc></sitemap>
  <sitemap><loc>https://www.example.com/sitemap-key-pages.xml</loc></sitemap>
</sitemapindex>
```

## Example: splitting Ledgerline's sitemap

1. The developer changed the CMS export to write one file per section plus a hand-maintained key-pages file.
2. The SEO lead submitted the index file and removed the old single sitemap from the report.
3. A week later, Page indexing filtered to the key-pages sitemap showed two product pages as Crawled - currently not indexed, which the single sitemap had hidden among blog URLs.

## Where this fits in the monthly routine

In week 2, confirm each sitemap shows Success and a recent Last read date. After any CMS or CDN change, check the same day instead of waiting for the routine.

## Quick checks before you move on

- Every sitemap shows Success.
- The key-pages sitemap exists and lists only canonical, indexable URLs.
- robots.txt references the sitemap index.

## Worked example: Ledgerline's split sitemaps

*Ledgerline is a fictional accounts-payable software company. Details and numbers are illustrative.*

Ledgerline had one sitemap with every URL. After splitting it into products, blog, glossary and help, the sitemap filter in Page indexing showed product and blog pages almost fully indexed while many glossary entries sat in "Crawled - currently not indexed". The content team merged short entries into fuller ones and added internal links from related guides.

### Walkthrough

1. Open **Indexing > Sitemaps**.
2. Read the **Submitted sitemaps** table: status, last read date and discovered pages.
3. Click a sitemap to see details, then **See page indexing** to open Page indexing filtered to it.
4. To add one, type the sitemap URL into **Add a new sitemap** and click **Submit** (owners only).
5. If a status is Couldn't fetch, open the URL in a browser and check robots.txt.
6. After a site restructure, resubmit the sitemap index and check again in a few days.

## Try it yourself

Split your sitemap by content type if it isn't already (or ask your developer to). Submit each one, then compare indexing rates across sitemaps in Page indexing. Write down which content type has the lowest indexing rate and one reason why.

## Quick quiz

**1. Who can submit a sitemap in the report?**

*Answer:* Owners. Others can reference a sitemap in robots.txt.

**2. What is the size limit of one sitemap?**

*Answer:* 50MB uncompressed or 50,000 URLs.

**3. Does submitting a sitemap guarantee indexing?**

*Answer:* No. It helps discovery; Google still decides.

**4. Do small sites need a sitemap?**

*Answer:* Not always. Google says sites of about 500 pages or fewer that are well linked may not need one.

## What should you check before the next lesson?

- Your sitemaps show Success.
- Sitemaps are split by content type, or you have asked for it.
