Rank Math WordPress Plugin Duplicate Sitemap Bug
4 min readWell-known WordPress Search engine marketing plugin, Rank Math, has been identified to have a bug that causes it to generate replicate sitemap information. This strange bug in how sitemaps are generated is identical to a person that has an effect on Yoast, but the way Rank Math handles it is unique.
Web page Sitemap
A sitemap is an significant component of lookup motor optimization. It tells research engines which webpages have been freshly included to a web-site and which web pages have been updated.
The sitemap can help a search engine prioritize their site crawling by alerting it to new written content that requires to be indexed.
Because of the worth of a sitemap for Search engine optimization, it is a excellent observe that sitemaps are generated properly.
Google’s developer site about sitemaps says:
“A sitemap is a file where you deliver details about the internet pages, films, and other data files on your site, and the relationships between them.
Research engines like Google go through this file to crawl your web site more effectively.
A sitemap tells Google which web pages and documents you consider are crucial in your web-site, and also offers precious data about these data files. For example, when the page was very last up-to-date and any alternate language versions of the page.”
Rank Math XML Sitemap Bug
Rank Math also generates multiple XML sitemaps. In actuality, it generates quite possibly an infinite variety of XML sitemaps.
For instance, a web site with a one sitemap for “posts” will deliver the adhering to replicate sitemaps:
/article-sitemap.xml /post-sitemap1.xml
But it will not create the zero numbered variant, /write-up-sitemap0.xml
The same is true for replicate sitemaps generated for web pages:
/web site-sitemap.xml /web page-sitemap1.xml
And all over again, just like for the “posts” sitemaps, Rank Math does not deliver the zero-numbered sitemap variant: /website page-sitemap0.xml
Rank Math Generates Infinite Quantity of Sitemaps?
While Rank Math does not deliver the zero-numbered sitemap variant, Rank Math does generate what appears to be a in close proximity to infinite amount of numbered XML sitemaps.
Ideally, Rank Math ought to create a 404 response code for sitemaps that really don’t exist.
But what seems to be going on is that as an alternative of creating a 404 response message Rank Math is building a 200 reaction code (indicating it’s a request for a legitimate internet website page) and then creating an empty XML sitemap.
The subsequent is a URL that I analyzed to see what Rank Math created:
https://rankmath.com/post-sitemap9.xml
This is what Rank Math demonstrates:
Non-existent Website Map Generated by Rank Math
How lots of sitemaps will Rank Math make?
Evidently, Rank Math might make a good deal of URLs, perhaps an infinite quantity of XML sitemap webpages.
I was ready to produce a blank sitemap with this URL:
https://rankmath.com/submit-sitemap9999999999999999999999999999999999999999999.xml
What is of fascination about the higher than sitemap is that the server generates a 200 header reaction code to a browser when serving that XML web page map.
The 200 response code usually means that there is no error.
I confirmed whether or not Rank Math created a 200 reaction code by using the HTTPStatus web-site.
This exhibits that Rank Math generates a 200 reaction code for webpages that do not exist:
Rank Math Sitemap Redirect Behavior
Other Seo plugins have a bug that creates a replicate sitemap when the number zero is included to the conclusion of a sitemap URL.
Rank Math even so does not generate a replicate sitemap with the quantity zero.
When you make a ask for for the non-existent zero-numbered sitemap, the ask for triggers a redirect to the canonical sitemap.
A ask for for this non-existent sitemap:
/webpage-sitemap0.xml
Redirects to the canonical sitemap:
/webpage-sitemap.xml
But that is arguably not a appropriate way to handle a sitemap that does not exist.
The appropriate server reaction should be to demonstrate a 404 Web site Not Uncovered Error Response concept, since that’s what occurred, the web page was not observed.
The Yoast Search engine optimisation plugin responds in the accurate manner by serving a 404 reaction code for XML sitemaps that really don’t exist (apart from for the zero and 1-numbered variants).
I requested Rank Math about it and they explained that it is not an concern at all.
Rank Math:
“This is identical to how WP core handles on-site lookup: you will receive HTTP 200 reaction for any arbitrary search query.
Contrary to some sitemap plugins, Rank Math does not make bodily sitemap data files in the server’s root listing.
Given that these non-existent sitemap URLs are not current wherever on the site, Google and other research engines will under no circumstances crawl them, so this shouldn’t bring about any concern from an Search engine marketing level of perspective.”
Rank Math Copy Web site Map Bug
It is fascinating that Rank Math, like a several other Search engine optimisation Plugins, has a duplicate web page map bug.
When it comes to optimizing a internet site for search engines, the aim is to be as excellent as attainable. Everything that makes a web page a lot less than great can be considered a flaw when perfection is the aim.
Considerably less than excellent optimization can guide to unforeseen repercussions.
Yoast is aware of the challenge and is explained to be doing the job on a deal with. Just one would hope that the duplicate internet site map issue with Rank Math will also be set at some level.
