If you're searching for “sitemap taxonomy detail”, there's a good chance you've encountered an XML sitemap containing categories, tags or another type of taxonomy and you're trying to understand exactly what you're looking at.
The terminology sounds considerably more complicated than the basic concept.
A taxonomy is essentially a system for organizing related content.
And a taxonomy sitemap provides search engines with URLs for those organizational pages when they're intended to be publicly discoverable.
What Does Sitemap Taxonomy Mean?
WordPress provides the easiest example.
WordPress uses taxonomies to organize content.
The two taxonomies most website owners recognize are:
- Categories
- Tags
Suppose you operate a website about personal finance.
You might have categories such as:
- Credit Cards
- Mortgages
- Investing
- Insurance
- Taxes
Each category can have its own archive page containing the articles assigned to that category.
Those category archive pages are taxonomy URLs.
WordPress Can Put Taxonomy Pages in Its XML Sitemap
This isn't an error.
WordPress has included native XML sitemap functionality since WordPress 5.5.
Its sitemap system contains a dedicated taxonomy provider called WP_Sitemaps_Taxonomies.
According to WordPress developer documentation, the provider retrieves public registered taxonomies and can generate URL lists for taxonomy sitemaps.
That means categories, tags and qualifying custom taxonomies can potentially appear within the WordPress sitemap system.
You might encounter a URL resembling:
/wp-sitemap-taxonomies-category-1.xml
That doesn't mean WordPress somehow created another copy of every article.
It's providing search engines with URLs associated with taxonomy terms such as your category archive pages.
What Is a Taxonomy Term?
The distinction between a taxonomy and a taxonomy term can initially be confusing.
Think of it this way:
Taxonomy: Category
Terms:
- Technology
- Business
- Finance
- Travel
Or:
Taxonomy: Product Brand
Terms:
- Apple
- Samsung
- Microsoft
WordPress can also support custom taxonomies created by themes, plugins or custom development.
Why Would Taxonomy Pages Be Included in a Sitemap?
Because some taxonomy pages are legitimate webpages worth discovering.
Imagine a category page containing:
- A useful introduction to the subject
- Twenty relevant articles
- Helpful navigation
- Unique content
- Internal links
That page could provide genuine value to visitors.
In that situation, allowing search engines to discover the taxonomy archive can make sense.
A sitemap provides another mechanism through which search engines can find that URL.
Does Putting a Taxonomy in Your Sitemap Improve Rankings?
Not automatically.
A sitemap is primarily about discovery and crawling.
Including a category in sitemap.xml doesn't magically make that category rank.
The page still needs to be useful.
This is particularly important with tags.
Too Many Thin Tag Pages Can Create a Mess
Imagine publishing 100 articles and creating 300 different tags.
Some tag pages contain only one article.
Others contain almost identical collections of posts.
Now your website has hundreds of archive URLs without much unique value.
Automatically putting every one of those URLs into a sitemap doesn't necessarily improve your SEO.
The better question is:
Do I actually want search engines treating this taxonomy archive as a useful destination?
If the answer is no, you may want to reconsider whether that taxonomy should be indexable or included in your sitemap.
Categories and Tags Aren't Automatically Bad for SEO
There's a tendency to oversimplify technical SEO advice.
You'll sometimes hear:
“Never index tags.”
or:
“Always index category pages.”
Neither rule makes sense for every website.
A carefully designed category page can be an excellent navigation and search destination.
A carefully curated tag archive can also be useful.
A taxonomy becomes problematic when it generates large numbers of thin, duplicate or meaningless pages simply because the CMS can create them.
Custom Taxonomies Can Be Extremely Useful
Taxonomies aren't limited to blog categories.
A sophisticated website might organize content by:
- Location
- Product type
- Brand
- Industry
- Author
- Skill level
- Property type
- Service category
For example, a real-estate website could have a custom taxonomy called:
Property Type
with terms such as:
- Condo
- Detached House
- Townhouse
- Commercial Property
If those archive pages are useful to people searching for properties, including them in the sitemap can make perfect sense.
Should Your Taxonomy Sitemap Include Empty Categories?
Generally, there's little reason to send search engines toward empty archive pages.
WordPress's native taxonomy sitemap query is designed to retrieve non-empty taxonomy terms by default.
WordPress developer documentation shows that the taxonomy sitemap provider uses hide_empty = true when querying terms.
That's sensible.
A category containing nothing doesn't provide much value to either a visitor or search engine.
What If You See a Strange Taxonomy Sitemap?
If you encounter something such as:
sitemap-taxonomy-category.xml
sitemap-taxonomy-post_tag.xml
or:
wp-sitemap-taxonomies-category-1.xml
don't immediately assume your website has been hacked or something is broken.
Your CMS or SEO plugin may simply be generating separate sitemap files for different content types.
Open the sitemap.
Look at the URLs.
Then ask:
Do I actually want search engines discovering these pages?
Need a Basic XML Sitemap? Use Our Free Generator
If all of this taxonomy terminology sounds more complicated than what you actually need, don't overcomplicate your website.
For a smaller public website, you can use the RichInWriters Free XML Sitemap Generator.
The tool scans up to 50 public pages, follows internal links and creates a downloadable sitemap.xml file.
It's particularly useful for smaller websites that don't already have automatic sitemap generation built into their CMS.

WordPress Users May Not Need Another Sitemap Generator
If you're using a modern WordPress website, check:
https://yourwebsite.com/wp-sitemap.xml
before creating another sitemap.
You may discover that WordPress is already generating post, page and taxonomy sitemaps automatically.
SEO plugins can also modify or replace the native WordPress sitemap system.
Running several sitemap systems simultaneously without understanding what each one does can create unnecessary confusion.
When Sitemap Taxonomy Becomes a Coding Problem
Sometimes the issue goes beyond changing a plugin setting.
You may have a custom post type.
You may need a custom taxonomy included while excluding another.
Your sitemap might contain URLs that shouldn't exist.
A custom taxonomy could be returning 404 errors.
Your application might generate thousands of parameterized URLs.
Or you may need sitemap generation designed specifically around a custom PHP application.
WordPress itself provides developer filters for controlling taxonomy sitemap behavior, including filters affecting which public taxonomies are available and individual taxonomy sitemap entries.
That's powerful—but it also means you're now dealing with code rather than simply clicking a checkbox.

Final Thoughts on Sitemap Taxonomy Details
If you searched for sitemap taxonomy detail, you probably don't need another complicated definition.
The basic concept is:
A taxonomy organizes content. A taxonomy term represents one group inside that taxonomy. A taxonomy sitemap helps search engines discover the public archive pages associated with those terms.
Categories and tags are the most familiar examples, but custom taxonomies can organize almost anything.
The SEO question isn't whether taxonomy sitemaps are universally good or bad.
It's whether the pages being included are actually useful pages you want search engines to discover.
If you simply need to generate a sitemap for a smaller website, use the RichInWriters Free XML Sitemap Generator.
If you've reached the point where custom taxonomies, sitemap filters, WordPress code or application architecture are causing the problem, consider getting technical assistance from WebmasterSolutions.ca.
