It seems to me that it could be a good idea to sort the pages of the sitemap.xml by
It doesn’t change anything for the search engines which read all the pages of the sitemap without taking into account the order.
But there is a big difference if the sitemap is versioned in git. Currently, a sitemap can be different at each compilation, creating another commit while nothing really changes.
If the URLs are sorted by
.Permalink, an identical sitemap will not create another commit.
Maybe this is only interesting for me (I also version
/public/ for some sites), but I can do a pull request if the approach seems interesting to others.
You can replace the internal sitemap template with your own sitemap template in the layouts directory. There you can sort and add any additional features you like. I don’t think that an optimization of generated output, because the output might be added to a git repository, might not be a feature for the majority.
Check the docs for the initial layout file and then copy to your layout directory and edit. Hugo will then take those instead of the internals.
I already have a special sitemap.xml for my website
You are right. Sorting is (maybe) relevant for small sites. But probably not for sites with a thousand pages. So, I keep my pimped
sitemap.xml for my particular site.
I wonder if maybe sorting is somehow cached. You would sort items for the list pages display anyway, so if Hugo somehow caches this sorted display it might be reused somehow.
I am unable to reproduce this. The sitemap ranges through
.Pages using the default sort order; this is not an indeterminate sort.
Yes, the sort order will change if you modify
title/linkTitle, or the
path. As you suggest, we could prevent the sort order from changing if we sorted by
.Permalink, but the sitemap would still change because it contains a
Your answer is very helpful. It was the parameter
weight that had caused the problem that made me think of a random order.
Indeed, a page whose content does not change at all, its URL neither and its date neither (if
lastmod are manually filled) can change place in the
sitemap.xml because of
It’s not a problem at all, but now I know why! Thank you very much.
