If you use Blogger (Blogspot) as your blogging platform, you may have noticed that sometimes your blog URLs end with parameters like ?m=1 or ?m=0. These codes often appear when your website is opened on different devices, especially smartphones.
Although these parameters are part of Blogger’s default system, many bloggers prefer to remove them because they can make URLs look messy and potentially create duplicate versions of the same page.
In this guide, you will learn what ?m=1 and ?m=0 mean, why they appear, and how to remove them from your Blogger URLs to keep your website cleaner and more SEO-friendly.
What Are ?m=1 and ?m=0 in Blogger?
The parameters ?m=1 and ?m=0 are used by Blogger to determine whether a page is being viewed on a mobile device or desktop device.
Here is what each parameter means:
?m=1→ The page is displayed in mobile mode.?m=0→ The page is forced into desktop mode, usually when desktop view is selected on a mobile browser.
For example:
Normal URL:
https://yourblog.blogspot.com/2026/03/example-article.html
Mobile version:
https://yourblog.blogspot.com/2026/03/example-article.html?m=1
Desktop mode on mobile:
https://yourblog.blogspot.com/2026/03/example-article.html?m=0
Even though these URLs show the same content, search engines may treat them as different URLs. This can sometimes lead to duplicate indexing if not handled properly.
Why Many Bloggers Remove ?m=1 from Blogger URLs
Although Blogger automatically manages mobile views, many website owners choose to remove these parameters for several reasons.
1. Cleaner and More Professional URLs
Short and clean URLs look more professional and are easier to share.
For example:
Before:
example.blogspot.com/article-title.html?m=1
After:
example.blogspot.com/article-title.html
Clean URLs improve the overall appearance and credibility of your website.
2. Prevent Duplicate URLs
Search engines may sometimes crawl both versions of a page:
example.com/article.html
example.com/article.html?m=1
This can create duplicate URLs for the same content, which may affect SEO if not properly handled.
Removing the ?m=1 parameter ensures that only one clean URL is indexed.
3. Better User Experience
When visitors share links on social media or messaging apps, URLs that include extra parameters often look confusing.
Cleaner links:
- Are easier to read
- Look more trustworthy
- Are more likely to be clicked
4. Improved SEO Structure
While the ?m=1 parameter itself does not directly harm SEO, simplifying URLs can help search engines understand and index your website more efficiently.
Many SEO experts recommend keeping URLs short, consistent, and parameter-free whenever possible.
How to Remove ?m=1 and ?m=0 from Blogger URLs
One of the easiest ways to remove the ?m=1 parameter is by adding a small JavaScript snippet to your Blogger template.
This script automatically cleans the URL when the page loads.
Script to Remove ?m=1
<script type='text/javascript'>
var url = window.location.toString();
if (url.indexOf("?m=1") > 0) {
var clean_url = url.substring(0, url.indexOf("?m=1"));
window.history.replaceState({}, document.title, clean_url);
}
</script>
This script detects if the URL contains ?m=1 and automatically removes it from the browser address bar.
Step-by-Step Guide to Install the Script in Blogger
Follow these simple steps to add the script to your Blogger theme.
Step 1: Log in to Blogger
Go to www.blogger.com and sign in using your Google account.
Step 2: Open the Theme Menu
From the Blogger dashboard:
- Click Theme
- Select Edit HTML
This will open the template editor.
Step 3: Add the Script to Your Template
Scroll down in the HTML editor and find the closing </body> tag.
Paste the script right above the </body> tag.
Example:
<script type='text/javascript'>
var url = window.location.toString();
if (url.indexOf("?m=1") > 0) {
var clean_url = url.substring(0, url.indexOf("?m=1"));
window.history.replaceState({}, document.title, clean_url);
}
</script>
</body>
Step 4: Save the Template
Click Save Theme to apply the changes.
After saving, open your blog using a smartphone or different browser to confirm that the ?m=1 parameter no longer appears in the URL.
Additional Tips to Improve Blogger SEO
Removing the ?m=1 parameter is just one small step toward better SEO. Here are some additional tips to optimize your Blogger website.
1. Use SEO-Friendly Permalinks
Make sure your article URLs include clear keywords related to your topic.
Example:
how-to-remove-m1-from-blogger-url.html
Avoid very long or confusing URL structures.
2. Submit Your Sitemap to Google Search Console
Submitting a sitemap helps Google discover and index your blog content faster.
Typical Blogger sitemap:
https://yourblog.blogspot.com/sitemap.xml
3. Use Responsive Templates
Modern Blogger templates are fully responsive, meaning they automatically adjust to different screen sizes without using mobile parameters.
Using a responsive theme can reduce the appearance of mobile-specific URL parameters.
4. Improve Internal Linking
Linking between your own articles helps search engines crawl your website more effectively and improves overall SEO performance.
Is Removing ?m=1 Safe for Blogger?
Yes, removing the ?m=1 parameter using JavaScript is generally safe and widely used by Blogger users.
However, keep in mind that:
- The script only changes the visible URL in the browser
- It does not affect the actual page content
- Blogger still manages mobile layouts automatically
This method simply helps maintain clean and consistent URLs.
Conclusion
The ?m=1 and ?m=0 parameters in Blogger URLs appear because Blogger automatically adjusts the layout depending on the device used to access your blog.
Although these parameters are part of Blogger’s system, many bloggers prefer to remove them in order to:
- Keep URLs cleaner and more professional
- Avoid duplicate page versions
- Improve link sharing and readability
- Maintain a better overall SEO structure
By adding a simple JavaScript code to your Blogger template, you can easily remove these parameters and ensure that your blog URLs remain clean and user-friendly.
If you manage a Blogger website and want a more polished and SEO-optimized blog, removing the ?m=1 parameter is a small but effective improvement.
