If you use Blogger or Blogspot, you may have noticed that your website URL sometimes ends with ?m=1, especially when you visit a page from a mobile phone.
For example, your normal Blogger post URL may look like:
https://example.com/2026/09/sample-post.htmlBut on a mobile device, you may sometimes see:
https://example.com/2026/09/sample-post.html?m=1This often leads Blogger users to search for how to remove ?m=1 from Blogger URLs, especially after seeing mobile URLs, redirect messages, duplicate pages or canonical notices inside Google Search Console.
But is ?m=1 bad for Blogger SEO? Does it create duplicate content? Should you remove it with JavaScript, redirects or robots.txt?
In most cases, you do not need to remove ?m=1 from Blogger URLs. It is part of Blogger's mobile URL handling, and incorrectly forcing it to disappear can create more technical SEO problems than it solves.
In this guide, you will learn what ?m=1 means in Blogger, how Google handles these mobile URLs, whether they affect SEO, and what you should check instead of trying to remove them.
What Does ?m=1 Mean in Blogger?
The ?m=1 parameter is associated with Blogger's mobile URL handling. Blogger may append it when a page is requested or displayed through its mobile behavior.
The question mark begins a URL query parameter, while m=1 represents the mobile version.
For example:
Normal Blogger URL:
https://example.com/2026/09/blogger-seo-guide.htmlMobile Blogger URL:
https://example.com/2026/09/blogger-seo-guide.html?m=1Both URLs normally represent the same main page content. The second URL is simply a parameterized version generated through Blogger's mobile handling.
What Is ?m=0 in Blogger URLs?
You may occasionally see ?m=0 as well.
In Blogger's URL handling:
- ?m=1 is associated with the mobile view.
- ?m=0 can be associated with requesting the desktop view.
Neither parameter should normally be treated as the permanent permalink for your article.
Your preferred Blogger URL should remain the clean canonical version:
https://example.com/2026/09/my-blogger-post.htmlrather than:
https://example.com/2026/09/my-blogger-post.html?m=1Does ?m=1 Affect Blogger SEO?
The presence of ?m=1 does not automatically damage your Blogger SEO.
The more important issue is whether Google can understand which URL is the preferred version of the page.
Search engines regularly discover multiple URLs containing identical or very similar content. Google uses a process called canonicalization to determine which URL should generally be treated as the main version.
For example, Google may discover:
https://example.com/post.html
https://example.com/post.html?m=1Your Blogger website should normally indicate that the clean URL is the canonical version:
https://example.com/post.htmlGoogle can then consolidate signals from alternate versions instead of treating every URL parameter as an independent page.

Does ?m=1 Create Duplicate Content?
Google may technically be able to access substantially the same Blogger content through both the clean URL and the ?m=1 mobile URL.
However, that does not automatically mean your website has a harmful duplicate-content problem.
Search engines regularly encounter alternate URL versions created by:
- Mobile parameters
- Tracking parameters
- Filters
- Sorting parameters
- HTTP and HTTPS variations
- www and non-www variations
The important part is providing consistent canonical signals.
Therefore, your goal should not simply be:
"How can I make ?m=1 disappear?"
A better technical SEO question is:
"Does Google understand which version of my Blogger URL is canonical?"
Should I Remove ?m=1 From Blogger URLs?
For most Blogger websites, you should not try to manually remove ?m=1 solely for SEO purposes.
Blogger does not provide a normal setting that permanently disables this mobile URL behavior across every request.
You may find tutorials online offering JavaScript that detects ?m=1 and then rewrites or redirects the URL.
Although these scripts may make the address bar appear cleaner, changing what appears in the browser is not necessarily the same as correcting Blogger's server-side URL handling.
If Blogger already handles the alternate URL and supplies an appropriate canonical URL, adding another redirect or JavaScript layer is usually unnecessary.
Why JavaScript ?m=1 Removal Can Cause Problems
Many tutorials claiming to remove ?m=1 from Blogger URL use JavaScript similar to this general process:
- Detect whether the URL contains
?m=1. - Remove the query parameter.
- Reload, redirect or rewrite the browser URL.
The problem is that Blogger may already be performing its own mobile URL handling.
Adding custom URL manipulation can potentially introduce:
- Redirect loops
- Unnecessary redirects
- Inconsistent mobile URLs
- Conflicting canonical signals
- Crawling problems
- Additional JavaScript execution
For SEO, a correctly configured canonical URL is more useful than cosmetically hiding ?m=1 from visitors.
Should I Block ?m=1 URLs in Robots.txt?
Generally, you should not block ?m=1 URLs in robots.txt simply because you do not want those URLs indexed.
A robots.txt rule controls crawling. It is not a canonicalization tool.
If Google cannot crawl a URL, it may also be unable to inspect important page-level signals associated with that URL.
Instead of trying to block every Blogger mobile URL variation, concentrate on making your canonical URLs clear and consistent.
What Does "Alternate Page With Proper Canonical Tag" Mean?
A common reason Blogger users become concerned about ?m=1 is the Alternate page with proper canonical tag status in Google Search Console.
For example, Google may discover:
https://example.com/post.html?m=1but recognize this as the canonical page:
https://example.com/post.htmlIf Search Console reports the ?m=1 URL as an alternate page with the proper canonical, that generally means Google understands that another URL is the preferred version.
You do not need every URL Google discovers to be independently indexed.
For duplicate or alternate versions of the same content, having Google index the preferred canonical URL is normally the desired outcome.
What About Blogger ?m=1 Redirect Errors in Search Console?
You may also encounter Redirect error inside Google Search Console for certain Blogger URLs.
Because Blogger has built-in mobile URL handling, Googlebot may encounter redirects involving mobile URL parameters.
Do not assume that seeing a ?m=1 URL automatically means your entire site has an indexing problem.
Instead, check whether:
- Your clean canonical post URL is accessible.
- Your important posts are indexed.
- The canonical tag points to the correct URL.
- Your Blogger theme does not contain custom redirect scripts.
- You have not added conflicting canonical tags.
If your important canonical URLs are being indexed correctly, an excluded alternate URL may not require any action.
How to Check the Canonical URL in Blogger
Instead of immediately trying to remove ?m=1, first check whether your Blogger template outputs the correct canonical URL.
Open one of your Blogger posts in a browser and view the page source.
Search for:
rel="canonical"You should normally find something similar to:
<link rel="canonical" href="https://example.com/2026/09/post.html">The canonical URL should normally be the clean page URL without ?m=1.
In many Blogger templates, the canonical tag is generated dynamically with Blogger's canonical URL data, for example:
<link expr:href='data:blog.url.canonical' rel='canonical'/>If your clean URL is correctly declared as canonical, there is generally no reason to add another canonical tag manually.
Check Blogger ?m=1 URLs in Google Search Console
Google Search Console's URL Inspection tool can help you understand which URL Google considers canonical.
Start by inspecting your clean post URL:
https://example.com/post.htmlLook for:
- User-declared canonical
- Google-selected canonical
Ideally, both should point to your clean Blogger post URL.
You can also inspect the mobile variation:
https://example.com/post.html?m=1If Google recognizes the clean version as canonical, the mobile parameter itself normally does not need to be removed.
Should ?m=1 URLs Be Added to the Blogger Sitemap?
No. Your Blogger sitemap should focus on the normal canonical URLs of your posts and pages.
You do not need separate sitemap entries for:
post.html
post.html?m=1The clean canonical URL is the version you want search engines to associate with your content.
The same principle applies when requesting indexing through Google Search Console. Request indexing for the clean post URL rather than submitting every mobile URL parameter variation.
Does Removing ?m=1 Improve Blogger Page Speed?
Removing ?m=1 from the browser address bar does not automatically improve your Blogger website's Core Web Vitals or page speed.
Blogger performance is more heavily affected by:
- Large images
- Unused JavaScript
- Third-party scripts
- Fonts
- Theme code
- Widgets
- Advertising scripts
- Render-blocking resources
Adding additional JavaScript solely to manipulate the URL may actually introduce code without producing a meaningful performance benefit.
Does a Custom Domain Remove ?m=1 From Blogger?
Connecting a custom domain to Blogger gives your site a professional domain such as example.com instead of an address ending in blogspot.com, but a custom domain does not necessarily eliminate Blogger's mobile URL handling.
The same ?m=1 behavior can still appear with Blogger custom domains.
If you have not yet connected your own domain, follow our step-by-step guide to adding a custom domain to Blogger, including CNAME, DNS, HTTPS and redirect configuration.
When Should You Investigate a Blogger ?m=1 Problem?
Seeing ?m=1 by itself is usually not a reason to edit your Blogger template.
You should investigate further when there is evidence of a genuine technical SEO issue, such as:
- Your canonical tag is missing.
- The canonical tag points to the wrong URL.
- Google repeatedly chooses an unexpected canonical URL.
- Your clean Blogger posts cannot be crawled.
- Important canonical posts remain unindexed.
- Your sitemap contains incorrect URL variations.
- A custom script creates redirect loops.
- Your theme contains multiple conflicting canonical tags.
In these situations, diagnose the underlying crawling, indexing, redirect or canonicalization problem instead of automatically assuming ?m=1 is the cause.
Best SEO Practice for Blogger ?m=1 URLs
For most Blogger websites, the safest SEO approach is straightforward:
- Keep the correct canonical URL on your Blogger posts and pages.
- Use clean canonical URLs in your internal links.
- Submit canonical URLs through your Blogger sitemap.
- Inspect important pages with Google Search Console.
- Make sure Google selects the correct canonical URL.
- Avoid unnecessary JavaScript redirects designed only to hide
?m=1. - Do not block mobile URL parameters solely because they appear in Search Console.
- Remove old URL-rewriting scripts if they are causing redirect or crawling problems.
The objective is not to make every possible URL variation disappear. The objective is to send search engines consistent signals about which URL represents the main version of your content.
Frequently Asked Questions About Blogger ?m=1
Is ?m=1 Bad for Blogger SEO?
No. ?m=1 is not inherently bad for SEO. It is associated with Blogger's mobile URL handling. The more important SEO factor is whether Google correctly understands and indexes your clean canonical URL.
Should I Remove ?m=1 From Blogger URLs?
Usually, no. If Blogger automatically adds ?m=1 and your canonical URL is correct, there is normally no need to install JavaScript or redirects simply to remove the parameter.
Does ?m=1 Cause Duplicate Content?
The clean URL and ?m=1 URL can represent substantially the same content, but Google uses canonicalization to determine the preferred version. Correct canonical signals are therefore more important than forcing the alternate URL to disappear.
What Does ?m=1 Mean in Blogger?
The ?m=1 query parameter is associated with Blogger's mobile version or mobile URL handling.
What Is ?m=0 in Blogger?
?m=0 can be associated with requesting Blogger's desktop version, while ?m=1 is associated with mobile handling.
Should I Block ?m=1 in Robots.txt?
Generally, no. Robots.txt controls crawling and should not be used simply as a method of canonicalizing Blogger mobile URLs.
Should I Request Indexing for ?m=1 URLs?
No. Request indexing for the clean canonical version of your Blogger post rather than separately requesting indexing for its ?m=1 variation.
Why Does Google Search Console Show ?m=1 URLs?
Google can discover alternate and parameterized URLs while crawling your site. Seeing ?m=1 under excluded, alternate or redirect reports does not automatically mean your canonical posts have an SEO problem.
Can a Custom Domain Fix Blogger ?m=1 URLs?
No. A custom domain changes your site's main domain name, but Blogger's underlying mobile URL behavior can still occur.
Final Verdict: Should You Keep or Remove ?m=1?
If your Blogger website automatically adds ?m=1 for mobile visitors, you normally do not need to remove it.
Instead, confirm that:
- Your clean Blogger URL is canonical.
- Your sitemap contains the clean URL.
- Your internal links point to canonical URLs.
- Google Search Console recognizes the correct canonical.
- Your theme is not creating conflicting redirects or canonical tags.
?m=1 is usually a Blogger URL behavior to understand, not an SEO error that must be removed.
If your canonical configuration is correct, leave Blogger's mobile URL handling alone and focus your SEO efforts on useful content, internal linking, crawlability, page speed and proper indexing.
