I can audit this sitemap, but two required items are missing, and both change the result.
-
Crawl results per URL (required). For each sitemap URL I need the HTTP status code, the canonical URL and the meta robots or X-Robots-Tag value. Without them I cannot tell which URLs redirect, error, canonicalize elsewhere or are noindexed, and that decides what to remove. A Screaming Frog list mode crawl of the sitemap gives all three. With about 80,000 URLs, a sample of a few thousand rows per page type is fine if you tell me which types they are.
-
Uncompressed file size (required for the file check). Google's limit is 50MB uncompressed, or 50,000 URLs, per sitemap. The 11MB you gave is the gzip size, which the limit does not count. Please unzip the file and send the byte count. You mentioned about 80,000 URLs in one file; I will confirm the count from the crawl before judging it against the 50,000 URL limit.
Things I noticed in your paste that the audit will cover: the priority and changefreq tags (Google ignores both), the arc-floor-lamp URL listed as both https and http, and the ?ref=home parameter URL.
Defaults I will apply unless you tell me otherwise: - Preferred protocol and host: https://shop.lumenlamps.example, inferred from most URLs in your paste and labeled as inferred. - lastmod: not judged, since no real edit dates were given.
Send the crawl export and the uncompressed size, and I will return the URL table, the counts by class, the remove and replace list and the file checks. I won't change the sitemap or resubmit it without your approval.
