“Duplicate Without User-Selected Canonical” on Blogger: What It Means and Whether You Need to Fix It

Many Blogger users get an email from Google Search Console that says: “New reason preventing your pages from being indexed: Duplicate without user-selected canonical.”

It sounds alarming, but in most cases it is not. This guide explains what the message means, which URLs usually trigger it, and the few cases where you should actually take action.

What does the message mean?

Sometimes one piece of content can be reached through more than one web address. Google calls these duplicates. When that happens, Google looks for a canonical URL, which is the address you consider the “main” version.

“Without user-selected canonical” means no clear main version was declared for those particular URLs, so Google picked one on its own and left the others out of its index.

This is not a penalty. Nothing is wrong with your site as a whole. Google is simply saying it found duplicate or near-duplicate URLs and chose which one to show.

Which Blogger URLs usually cause it?

Blogger automatically creates several kinds of addresses that are not real articles:

• Feed URLs, such as /feeds/posts/default or /feeds/1234567890/comments/default. These are RSS/Atom files made for machines and feed readers, not for people.
• Mobile versions of posts, such as post-name.html?m=1.
• Label pages, such as /search/label/SEO.
• Search and archive pages, such as /search?q=... or monthly archives.
• Different versions of your domain, such as http vs https, or www vs non-www.

Google does not need to index any of these. If your affected URLs are in this list, the message is harmless and you can leave it alone.

Step 1: Find out which URLs are affected

1. Open Google Search Console and go to Indexing → Pages.
2. Under “Why pages aren’t indexed,” click Duplicate without user-selected canonical.
3. Read the list under Examples.

Then sort the URLs into two groups:

• Harmless: feed URLs, ?m=1 URLs, label pages, search pages, archive pages.
• Needs attention: your real post or page URLs, the ones you want people to find on Google.

If you only see harmless URLs, you do not need to do anything. The “Validate fix” button is not necessary either, because nothing is broken.

Step 2: If a real post is affected, inspect it

1. Paste the post URL into the search bar at the top of Search Console and press Enter.
2. Compare User-declared canonical and Google-selected canonical.
3. If both match, the page is fine.
4. If Google picked a different URL, check whether you have another post with very similar content, or whether the same post is reachable through a different domain version.

Step 3: Check your Blogger crawler settings

In your Blogger dashboard, go to Settings and scroll to Crawlers and indexing.

• Leave Custom robots.txt on the default unless you know exactly what you are changing. The default already blocks search pages.
• If you enable Custom robots header tags, a common setup is: Home page tags all, Archive and search page tags noindex, Post and page tags all.

This keeps Google focused on your real posts and away from archive and label pages.

Step 4: Use one clean version of your site

If you use a custom domain, check that:

• Your site opens on https.
• Only one of www or non-www is your main address, and the other redirects to it. In Blogger this is under Settings → Custom domain.

This prevents the same post from existing at several addresses.

Step 5: Fix real content overlap

If two of your own posts cover almost the same topic, you can:

• Merge them into one stronger, more complete post, or
• Rewrite one so it answers a clearly different question.

Google prefers one helpful page over two similar ones.

Step 6: Request indexing for important posts only

After making changes, inspect your important post URL in Search Console and click Request indexing. Do this only for key pages. Submitting many URLs at once does not make Google faster.

Updates in the report can take several days to a few weeks. Be patient.

Quick summary

• Feed, ?m=1, label, search and archive URLs: harmless, ignore them.
• Real post URLs affected: inspect them and check for duplicate content or domain versions.
• Crawler settings: keep the defaults, or noindex archive and search pages.
• Domain: use one clean https version.
• Content: keep every post unique and useful.

Final thoughts

“Duplicate without user-selected canonical” looks scary in an email, but on Blogger it usually points to auto-generated URLs that were never meant to appear on Google. Check the example URLs first, and only act if your real posts are involved. Beyond that, the best long-term fix is simple: publish original, helpful content, one clear post per topic.
