Our Free XML Sitemap Generator is Causing Peculiar Indexation Issues, Any Debugging Tips?
We're seeing users report some really peculiar <b>indexation issues</b> in Google Search Console after submitting sitemaps generated by our tool. Itโs not a full, catastrophic failure, more like Google has selective blindness for certain URLs. It's almost as if some pages are just politely ignored, even when they're clearly listed in the sitemap. We've double-checked the basic XML structure, validated against all the sitemap protocols, and even peered into our server logs until our eyes crossed. Everything looks... normal-ish? We're scratching our heads if it could be a subtle canonicalization issue we're missing.
Here's a snippet from a recent 'successful' generation, which might be hiding a subtle clue:
<code>[2023-10-27 10:30:01] INFO: Sitemap generation for example.com completed successfully. (250 URLs) [2023-10-27 10:30:02] WARN: Some URLs might contain non-canonical redirects. (Ignored for sitemap inclusion) [2023-10-27 10:30:03] INFO: Sitemap submitted to Google Search Console via API. Status: 200 OK</code>Has anyone else encountered these kinds of subtle sitemap generation issues leading to selective indexation problems? What are your go-to debugging strategies for these kinds of ghost-in-the-machine scenarios where everything seems fine but clearly isn't? Any insights into common pitfalls with canonicalization or similar subtle SEO factors would be super helpful.
Thanks in advance!

Answered 2 hours agoFirst off, great detail in your post โ though "indexing issues" is a bit more common than "indexation issues" when we're talking about Google's process, I get what you mean! That WARN: Some URLs might contain non-canonical redirects. (Ignored for sitemap inclusion) line is your biggest clue. Your sitemap generator isn't acting quirky; it's doing its job by omitting URLs that it believes aren't the canonical version, which is generally good practice for a sitemap. The "peculiar indexation issues" likely stem from these omitted URLs not being presented to Google via the sitemap, forcing Google to discover them through other, often less efficient, means.
To debug this, you need to identify the specific URLs Google is "selectively ignoring" in Search Console. Then, for each of those URLs, investigate their canonicalization status outside of your sitemap generator. Check their rel="canonical" tags directly in the HTML, verify any server-side redirects (301s, 302s), and ensure there are no conflicting signals. Common culprits include inconsistent HTTP/HTTPS versions, trailing slash discrepancies, or even internal links pointing to non-canonical versions. Use Google Search Console's URL Inspection Tool for individual problematic URLs; it will tell you exactly what Google sees as the canonical. By fixing these underlying canonicalization problems, your sitemap generator will then include the correct, canonical URLs, improving Google's ability to crawl and index them efficiently, and ultimately helping your overall site architecture and optimizing your crawl budget.
Hope this helps your conversions!
