How to Fix Duplicate Content Issues in Blogger for Better Rankings in 2025

Duplicate content is one of the silent killers of SEO performance, especially on Blogger sites where automatic content duplication or improper configuration can cause serious ranking drops. If your blog struggles with ranking or experiences fluctuating traffic, duplicate content issues might be the culprit. In this in-depth 2025 guide, we’ll explore why duplicate content happens in Blogger, how it impacts your rankings, and most importantly, step-by-step solutions to fix it—boosting your site’s SEO and user experience.

What Is Duplicate Content and Why It Matters in Blogger SEO

Duplicate content refers to blocks of text or pages that appear in more than one place on the internet. Google and other search engines prefer unique content, and when they find identical or near-identical content on multiple URLs, they struggle to decide which one to rank.

On Blogger, common causes include:

Multiple URLs showing the same post content (e.g., with and without “www,” http vs https)
Labels pages duplicating content of posts
Archives and date-based URLs showing similar content
Printer-friendly or mobile versions indexed separately
Using reused or spun content without modification

Duplicate content dilutes link equity, wastes crawl budget, and confuses search engines, leading to poor rankings or even penalties.

Signs You Have Duplicate Content Issues on Blogger

Drop or instability in Google rankings or organic traffic
Multiple URLs showing the same page content in Google Search Console
Low average session duration and high bounce rate
Google indexing label/category pages instead of main posts

Step-by-Step Guide to Fix Duplicate Content Issues in Blogger (2025)

Step 1: Canonical URLs — Tell Google Your Preferred Page

Blogger has a built-in canonical tag feature, but you need to ensure it’s working correctly.

Go to Settings > Search preferences in your Blogger dashboard.
Under Custom Robots Header Tags, enable “Add custom robots header tags”.
Enable canonicalization by selecting noindex, follow for pages you want unindexed (like labels) and ensure posts have canonical URLs.

Alternatively, add canonical links manually in your theme’s HTML inside the <head> tag for posts:

<link rel="canonical" href="<data:blog.url/>" />

Step 2: Use Robots.txt to Block Duplicate URLs

Robots.txt tells search engines which parts of your site to crawl or avoid.

In Blogger dashboard, go to Settings > Crawlers and indexing > Custom robots.txt.
Enable custom robots.txt, then add rules to block label pages, print versions, or archive URLs that cause duplication.

Example robots.txt to block label pages and print versions:

User-agent: *
Disallow: /search
Disallow: /label/
Disallow: /archives/

Adjust rules based on your blog’s structure.

Step 3: Redirect Non-Preferred URLs to Preferred Ones

Set your Blogger blog to use either www or non-www domain.
In Blogger Dashboard, go to Settings > Basic > Publishing and enable redirects (e.g., from non-www to www).

This prevents duplicate content caused by URL variations.

Step 4: Noindex Label Pages and Other Low-Value Pages

Labels (categories) often duplicate content from posts. You can prevent Google from indexing these pages:

Go to Settings > Search preferences > Custom robots header tags.
For Label pages, add noindex, follow.
This keeps them excluded from search results but keeps links crawlable.

Step 5: Use Unique, Original Content Consistently

Ensure all posts and pages have unique content. Avoid:

Copy-pasting from other sites
Spinning content without adding value or rewriting
Publishing very similar versions of the same post

Step 6: Monitor and Fix Broken or Duplicate Meta Tags

Check duplicate meta titles and descriptions, which may confuse search engines. Use Google Search Console or SEO tools like Ahrefs to find and fix these.

Step 7: Use Pagination Properly for Archives and Label Pages

If you use archive or label pagination, ensure it is SEO-friendly:

Use rel="next" and rel="prev" tags for paginated pages in your theme’s <head> for Blogger.
This helps Google understand page relationships and avoid indexing duplicate content.
