WordPress duplicate content is not a problem you create it is a problem WordPress creates for you, automatically, by default. Every time you publish a post, WordPress generates multiple pages that contain the same or similar content: category archives, tag archives, author archives, date archives, and paginated versions of each. Without deliberate configuration, all of them get indexed by Google simultaneously.
This matters because Google does not like indexing the same content twice. When multiple URLs contain identical or near-identical content, Google must choose which version to show in search results and it often does not choose the one you want. Rankings fragment across URLs, link equity dilutes, and your core pages underperform because their authority is split with dozens of thin archive duplicates.
This guide shows you exactly where WordPress duplicate content comes from, how to find it, and how to fix every instance using Rank Math the recommended SEO plugin for Websites.
The 5 Places WordPress Creates Duplicate Content Automatically
Understanding where WordPress duplicate content originates is the first step to fixing it. None of these are caused by anything you did wrong — they are built into how WordPress organises and displays content.
1. Category Archive Pages
When you assign a post to the “SEO Guides” category, WordPress creates a category archive at /category/seo-guides/ that lists your posts. The excerpt displayed on this archive page is pulled directly from each post. If a post appears in two categories — say, “SEO Guides” and “Tutorials” — its excerpt appears on both archive pages. Google sees two near-identical pages. This is duplicate content.
2. Tag Archive Pages
Every tag you create generates a tag archive URL. If you tag a post with “WordPress” and “SEO” and “Technical SEO,” three separate archive pages are created. If those tags each only contain one or two posts, the archive pages are thin, nearly identical in structure, and offer no unique value to Google’s index.
3. Author Archive Pages
WordPress creates an author archive at /author/kia-selmonton/ that lists every post by that author. On a single-author blog like Technexies, this archive is essentially a duplicate of your homepage — same posts, same excerpts, different URL. Google sees it as a thin variation of content it has already indexed.
4. Date Archives
WordPress generates date-based archives automatically: /2026/, /2026/03/, /2026/03/07/. Each of these pages lists posts published in that time period. They offer no unique content — just the same posts shown on your category and homepage — and they become outdated the moment new content is published.
5. www vs Non-www and HTTP vs HTTPS Variations
If your site is accessible at both www.technexies.com and technexies.com, Google may index both as separate sites with duplicate content across every single URL. The same applies if both HTTP and HTTPS versions are accessible. This multiplies your entire site’s content across two or four URL variations.
Duplicate content does not automatically result in a Google penalty. Google’s own documentation clarifies that unless you are deliberately duplicating content to manipulate rankings, duplicate content usually results in ranking dilution rather than a penalty. But ranking dilution is still damaging — it means your best content is sharing authority with dozens of thin archive pages instead of concentrating it where it matters.
How to Find Duplicate Content on Your WordPress Site
Method 1 — Google Search Console Coverage Report
Go to Google Search Console → Indexing → Pages. Look for these specific statuses that indicate duplicate content: “Duplicate without user-selected canonical” means Google found pages with identical content and chose its own canonical URL rather than yours. “Duplicate, Google chose different canonical than user” means your canonical tag points to one URL but Google is choosing a different one — a sign your canonicals may be inconsistent. “Alternate page with proper canonical tag” means the page exists but Google is correctly deferring to the canonical you specified.
Method 2 — Screaming Frog SEO Spider
Download Screaming Frog (free up to 500 URLs) and crawl your site. Go to the Content tab → filter by “Duplicate Page Titles” and “Duplicate Meta Descriptions” — these reveal pages with identical metadata. Then go to Directives → filter by “Canonical” to review all your canonical tags in a single view and identify any that point to wrong URLs or that have no canonical set.
Method 3 — Google Search
Search for site:technexies.com in Google. Look through the results for multiple URLs showing similar content — particularly archive pages, paginated pages, or tag pages appearing alongside your main articles. If archive pages are appearing in Google search results for content that should be attributed to your main posts, you have indexing configuration issues to fix.
How to Fix Archive Page Duplicate Content With Rank Math
Go to Rank Math → Titles and Metas. Work through each archive type:
Author Archives
Single-author sites: Set Robots Meta to “noindex, follow.” This removes author archive pages from Google’s index without blocking Google from following links on the page. Done.
Date Archives
Always noindex date archives — they have no SEO value. Set Robots Meta to “noindex, follow” under the Date Archives section in Titles and Metas.
Tag Archives
Two approaches depending on how you use tags. If you use tags casually and inconsistently — just adding whatever comes to mind — set tag archives to noindex. If you use tags deliberately and consistently, with at least 4 to 5 posts per tag, keep them indexed but add a unique description to each tag under Posts → Tags → Edit to give Google a reason to index the page separately from your post content.
Category Archives
Do not noindex category archives. Category pages can rank for broad topic searches and bring in traffic independently of individual posts. Instead, write a unique description for each category page (Posts → Categories → Edit → Description field) and make sure the excerpt content on the archive is not identical to the full post — WordPress shows excerpts on archives by default, which is fine. The issue is only when you are showing full posts on archive pages. Check your theme settings and make sure archives show excerpts only.
How to Fix Canonical Tag Issues in WordPress
Rank Math adds canonical tags to every page automatically. But several WordPress situations produce incorrect auto-generated canonicals that need manual review.
How to check your canonical tags: On any published page, right-click → View Page Source → press Ctrl+F and search for “canonical.” You should see exactly one line:
<link rel="canonical" href="https://technexies.com/your-post-slug/" />
If you see two canonical tags, or the URL points to HTTP instead of HTTPS, or the URL differs from the actual page URL in any way, it needs to be fixed.
Fix HTTP canonicals on HTTPS sites: This happens when WordPress’s Site Address is set to HTTP instead of HTTPS. Go to Settings → General and confirm your WordPress Address and Site Address both start with https://. Update them if not. Then regenerate your sitemap to pick up the corrected URLs.
Fix paginated page canonicals: WordPress sometimes generates self-referencing canonicals on paginated category pages (/page/2/, /page/3/) instead of pointing them to the first page of the series. Go to Rank Math → Titles and Metas → Categories → find the Pagination settings and set canonical to point to the first page. This consolidates all paginated archive pages into one canonical source.
How to Fix www vs Non-www Duplicate Content
Decide: are you www.technexies.com or technexies.com? Both are fine — just pick one and enforce it consistently. Do not change this once your site has backlinks pointing to it.
Go to Settings → General. Make sure both “WordPress Address” and “Site Address” match your chosen format exactly — either both with www or both without. Save.
Contact your hosting provider or use your .htaccess file to add a redirect from the non-preferred version to the preferred version. For example, if you prefer non-www, redirect all www requests to non-www with a 301 redirect. Your host’s support team can do this in minutes if you are not comfortable with .htaccess.
Add both the www and non-www versions of your site as separate properties in Search Console if you have not already. Then go to Settings in the correct property and use the “Change of Address” tool to confirm your preferred version to Google.
How to Fix Paginated Duplicate Content
Pagination duplicate content occurs when your category archives have multiple pages — page 1, page 2, page 3 — and each page is indexed separately despite having near-identical structure and overlapping content.
The correct approach is to add a canonical tag on each paginated page pointing to page 1. Rank Math handles this through its Titles and Metas → Posts → Pagination settings. Enable “Canonical URL for Paginated Pages” and set it to point to the first page. This tells Google that /category/seo-guides/page/2/ is a variant of /category/seo-guides/ and should not be indexed independently.
An alternative approach used by some SEOs is the rel="next" and rel="prev" link attributes on paginated pages to indicate they are part of a series. However, Google officially deprecated support for these attributes in 2019 and no longer uses them for indexing decisions. The canonical approach is the currently recommended method.
Rank Math configuration is central to fixing duplicate content. If you have not set up Rank Math correctly, read our complete Rank Math SEO setup guide first every setting that affects indexing and canonicals is covered there.

Frequently Asked Questions
Q. Does WordPress automatically create duplicate content?
Yes. WordPress generates category archives, tag archives, author archives, date archives, and paginated versions of each all containing the same post excerpts as your main posts. Without deliberate noindex and canonical configuration, Google indexes all of them as separate pages. This is the most common source of duplicate content on WordPress sites and it requires no mistake on your part to occur.
Q. Will duplicate content get my WordPress site penalised by Google?
Duplicate content from WordPress archive pages will not result in a manual penalty. Google’s documentation is clear that accidental or technical duplicate content the kind WordPress generates automatically results in ranking dilution rather than a penalty. However, that dilution is real and measurable. Fixing it consolidates your authority on the pages that matter and improves their ranking performance.
Q. How do I fix duplicate content in WordPress without coding?
Rank Math handles the vast majority of WordPress duplicate content fixes through its Titles and Metas section, noindexing author, date, and tag archives takes about 10 minutes with no coding required. For www vs non-www fixes, your hosting provider can add the server-level redirect. For canonical tag corrections, Rank Math’s interface in the post editor lets you set or override canonical URLs on individual pages without touching any code.
Q. Should I noindex category pages in WordPress?
No, not unless a category has very few posts and no unique description. Category pages can rank for broad topic searches and bring in traffic independently of individual articles. The correct approach is to keep category archives indexed, write a unique description for each category, and make sure archives show post excerpts rather than full post content. This makes the category page genuinely distinct from the individual post pages it lists.
