Yoast Duplicate Sitemap Bug
What was found is that Yoast can also be producing duplicate sitemaps.
A website that solely has a single sitemap for “pages” could have the next sitemaps:
Yoast “Web page” Sitemaps Bug
Unique “Web page” Sitemap:
/page-sitemap.xml
Duplicate “Web page” Sitemaps:
/page-sitemap0.xml /page-sitemap1.xml
Yoast “Put up” Sitemap Bug
A website that solely has a single sitemap for posts could have the next sitemap:
Unique “Put up” Sitemap:
/post-sitemap.xml
Duplicate “Put up” Sitemaps:
/post-sitemap0.xml /post-sitemap1.xml
Yoast A number of Sitemaps for Posts
A website with a number of sitemaps for posts manifests the bug differently.
For instance, if a website has hundreds of posts and requires three sitemaps, their sitemaps could appear like this:
Unique “Posts” Sitemaps:
/post-sitemap1.xml /post-sitemap2.xml /post-sitemap3.xml
However with the Yoast sitemap bug, they now have two additional sitemaps which might be duplicates of the primary website map.
So within the above instance, that is the primary sitemap: /post-sitemap1.xml
These are the duplicates sitemaps of the unique first sitemap:
/post-sitemap.xml /post-sitemap0.xml

These URLs result in similar Yoast XML sitemaps:
https://yoast.com/post-sitemap.xml https://yoast.com/post-sitemap0.xml https://yoast.com/post-sitemap1.xml
Sitemap Bug Not Restricted to Yoast
What’s actually bizarre is that this sitemap bug shouldn’t be restricted to Yoast.
An identical bug may be discovered in lots of different website positioning plugins (however not in all of them).
It’s sort of bizarre that a number of website positioning plugins would exhibit related conduct as regards to a bug.
One thing to think about is that plugin makers are certain by the WordPress open supply license that dictates that plugins and themes for WordPress are thought of spinoff works. It is a longstanding problem that at one level was clarified by Matt Mullenweg himself in 2015.
Matt wrote:
“WordPress is below a license referred to as the GPL, which principally says you are able to do no matter you want with the software program, however should you distribute modifications or create spinoff works additionally they should be below the GPL. Consider it like a Artistic Commons Sharealike license.
Up to now individuals weren’t positive if themes for WordPress have been spinoff works and wanted to be GPL. In 2009 we obtained an out of doors authorized opinion that cleared up the matter saying that the PHP in themes undoubtedly needed to be GPL, and for CSS and pictures it was optionally available. Mainly everybody within the WP neighborhood went absolutely GPL, typically referred to as 100% GPL, for all of the information required to run their theme (PHP, JS, CSS, art work).”
So it could possibly be that sure approaches towards producing a sitemap could themselves be open supply and obtainable to all of the website positioning plugin firms to make use of and this will clarify why different website positioning plugins include the identical or related bug to the one which Yoast has.
