| FIX DUPLICATE CANONICAL ISSUE |
If you are using Blogger (Blogspot) and checking Google Search Console, you might see a scary message:
❌ Duplicate without user-selected canonical
Don’t panic. This is one of the most common SEO problems in Blogger, and the good news is — you can fix it yourself without any plugin or paid tool.
In this guide, I’ll explain:
- What this error actually means (simple language)
- Why it happens in Blogger
- Exact steps to fix it (tested)
- Common mistakes you must avoid
- Advanced fix if the error still doesn’t disappear
This guide is written for beginners + intermediate bloggers.
What Does “Duplicate without user-selected canonical” Mean?
In simple words:
Google is saying:
“I found multiple URLs with the same content, but you didn’t tell me which one is the main (original) URL.”
Because of this confusion, Google may:
- Skip indexing your post
- Index the wrong URL
- Reduce ranking power
Example of duplicate URLs in Blogger
https://tecbuzzr.blogspot.com/2026/02/sample-post.htmlhttps://tecbuzzr.blogspot.com/2026/02/sample-post.html?m=1http://tecbuzzr.blogspot.com/2026/02/sample-post.html
All show same content, but Google doesn’t know which one to prefer.
Why This Problem Is Very Common in Blogger
Blogger automatically creates multiple versions of the same page:
- Mobile URL (
?m=1) - HTTP & HTTPS versions
- Label / archive URLs
- Search & parameter URLs
If canonical tags are not set properly, Google flags it as duplicate.
How This Error Hurts Your Blog (Important)
If ignored:
- ❌ Posts won’t index
- ❌ Traffic stays stuck
- ❌ Google trust reduces
- ❌ New posts rank very slowly
So fixing this is mandatory if you want growth.
STEP 1: Use Correct Canonical Tag (MOST IMPORTANT)
Go to:
Blogger Dashboard → Theme → Edit HTML
Search for:
<rel='canonical'>
❌ Remove wrong canonical tags like:
<link href='https://yourblog.blogspot.com/post-url.html' rel='canonical'/>✅ Use this dynamic canonical tag instead:
<link expr:href='data:view.url.canonical' rel='canonical'/>📌 This tells Google:
“Always treat the main URL as canonical.”STEP 2: Redirect HTTP to HTTPS
Google treats HTTP and HTTPS as different URLs.
Go to:
Settings → Privacy & Security
Enable:
✅ HTTPS Availability
✅ HTTPS Redirect
*Wait 24 hours after enabling.
STEP 3: Fix Mobile Duplicate (?m=1) URLs
Blogger creates mobile URLs automatically.
Add this code before </head> in Theme HTML:
<b:if cond='data:blog.isMobile'> <meta expr:content='data:view.url.canonical' name='canonical'/></b:if>
This ensures:
- Desktop URL = canonical
- Mobile URL = ignored
STEP 4: Set Preferred Domain Correctly
In Google Search Console:
- Open your property
- Go to Settings → Domains
- Use only ONE version
- Either
https://wwworhttps://
Do NOT mix multiple versions.
STEP 5: Exclude Unnecessary Pages from Indexing
Blogger indexes many useless pages like:
/search- /label/
- /p/about.html
Go to:
Settings → Crawlers and indexing
Enable:
❌ No indexing for search pages
This reduces duplicate signals.
STEP 6: Request Reindexing (Important)
After fixing everything:
Go to Google Search Console
- Open Pages → Duplicate without user-selected canonical
- Click affected URL
- Choose Request indexing
⚠️ Don’t do this repeatedly. Once is enough.
Common Mistakes You MUST Avoid
🚫 Adding multiple canonical tags
🚫 Hardcoding homepage URL as canonical
🚫 Mixing custom domain & Blogspot domain
🚫 Blocking pages using robots.txt blindly
One wrong line can break SEO completely.
How Long Does Google Take to Fix This?
Usually:
- 3–7 days for crawl
- 1–3 weeks for full cleanup
Be patient. Google doesn’t update instantly.
Advanced Fix (If Error Still Shows)
If the issue persists even after all steps:
You may need:
- Custom canonical logic
- Parameter handling fix
- Clean internal linking
This is where most beginners get stuck.
Final Thoughts
“Duplicate without user-selected canonical” is not a penalty — it’s a configuration issue.
If you:
- Use correct canonical tag
- Force HTTPS
- Control mobile URLs
👉 Your posts WILL start indexing properly.
