What has changed in your sitemap?
Compare the status before and after a relaunch or update. New, removed and changed entries are displayed separately – with the previous and current lastmod values.
Compare two sitemap stands
Their results
Examine changes after a relaunch
Save your XML sitemap before the changeover. Afterwards, compare this status with the new sitemap. For remote URLs, check whether the page has been deleted intentionally and whether a suitable forwarding is needed. New URLs should be accessible, internally linked and intended for indexing.
What does “changed” mean?
The tool compares lastmod, changefreq and priority as registered values. A changed date does not occupy an actual content change. The page content is not retrieved here. Missing values and different spellings remain visible; path capitalization, final slashes and URL parameters are not merged.
Duplicate URLs are considered once; the first entry is retained. For invalid entries, missing namespace or incompletely loaded index files, the comparison shows limitations. “New” and “removed” then refer only to the recorded entries.
The field meaning and the XML format explain the Sitemap protocol.
Recognizable example: a new, a removed URL
For both sides, select “Insert XML” and copy these full sitemaps. The example.org addresses serve only as comparison data and are not retrieved.

The URL /old is omitted, /new is added. At /Guideline, Lastmod changes. “Changed” here refers to the Sitemap date; the checker has not demonstrated any change in the page content.

Frequent questions
Can I compare two files?
Yes. Select “Insert XML or load file” for both sources. The contents are transmitted to Seitenreport for evaluation.
Are sitemap indices supported?
Yes, if you specify the public URL of the index. The retrieval is limited to six XML files and 10,000 page URLs per stand. For larger sites, compare the individual partial sitemaps.
What does an unchanged lastmod say?
It only shows that the entered value has remained the same. The actual topicality of the page cannot be deduced from this alone.
