Navigating Blogger URLs: Deciphering and Optimizing the ?m=1 Parameter for SEO

If you’ve browsed your Blogger site on a mobile device, you’ve probably noticed an extra bit at the end of your page URL:

https://yourblog.blogspot.com/sample-post.html?m=1

This ?m=1 parameter isn’t random — it tells Blogger to display the mobile-friendly version of the page. While it’s harmless for most blogs, some site owners prefer cleaner URLs and worry about possible SEO implications.

In this guide, we’ll break down:

  • What ?m=1 means and why Blogger uses it

  • Whether you should remove or hide it

  • Methods to optimize your URLs for SEO

  • Best practices for cleaner Blogger URLs

1. What is ?m=1 and Why Does Blogger Use It?

In older Blogger themes, mobile and desktop versions were separate. The ?m=1 flag let Blogger know to serve the mobile version of the page, improving loading speed and layout for small screens.

Key Points:

  • ?m=1 = mobile version

  • No parameter = desktop version

  • Modern responsive themes may not rely on it, but many older templates still do

2. Should You Remove ?m=1?

From an SEO standpoint:

  • No major harm: Google treats the mobile and desktop versions as the same page if canonical tags are set correctly.

  • Branding concerns: Some bloggers don’t like sharing URLs with extra parameters.

  • Link-sharing issue: If shared with ?m=1, the messy URL can spread across social media.

Verdict: You don’t have to remove it for SEO purposes — but hiding it can improve URL cleanliness and user experience.

3. Method 1: Hide ?m=1 with JavaScript

You can strip the parameter visually without breaking Blogger’s mobile view.

JavaScript Code:

<script type='text/javascript'>
//<![CDATA[
var uri = window.location.toString();
if (uri.indexOf("?m=1") > 0) {
  var clean_uri = uri.substring(0, uri.indexOf("?m=1"));
  window.history.replaceState({}, document.title, clean_uri);
}
if (uri.indexOf("&m=1") > 0) {
  var clean_uri = uri.substring(0, uri.indexOf("&m=1"));
  window.history.replaceState({}, document.title, clean_uri);
}
if (uri.indexOf("%3D") > 0) {
  var clean_uri = uri.substring(0, uri.indexOf("%3D"));
  window.history.replaceState({}, document.title, clean_uri);
}
if (uri.indexOf("%3D%3D") > 0) {
  var clean_uri = uri.substring(0, uri.indexOf("%3D%3D"));
  window.history.replaceState({}, document.title, clean_uri);
}
//]]>
</script>

Steps to Implement:

  1. Go to Blogger Dashboard → Theme → Edit HTML

  2. Paste the code just below the <head> tag

  3. Save your changes

Note: This only changes the URL in the browser. The parameter is still processed server-side.

4. Method 2: Use Canonical Tags for SEO

If you’re concerned about duplicate content, add a canonical tag to point search engines to the main version of the page.

Example:

<link rel="canonical" href="https://www.example.com/your-page" />

Replace the link with your actual desktop URL.

Steps:

  1. Blogger Dashboard → Theme → Edit HTML

  2. Paste the canonical tag inside the <head> section

  3. Save your theme

Blogger usually sets canonical tags automatically, but adding them manually ensures accuracy.

5. Best Practices for SEO-Friendly Blogger URLs

To optimize your blog’s URLs beyond the ?m=1 issue:

  • ✅ Make them descriptive: Include main keywords in the URL.

  • ✅ Keep them short: Avoid unnecessary words or numbers.

  • ✅ Use hyphens: For readability (healthy-fruit-recipes instead of healthyfruitrecipes).

  • ✅ Avoid changing URLs often: Stability helps with SEO.

  • ✅ Enable HTTPS: Improves trust and search rankings.

Conclusion

The ?m=1 parameter is a normal part of Blogger’s mobile optimization and doesn’t harm SEO if handled properly. If you want a cleaner look:

  • Use JavaScript to hide it from visitors

  • Add canonical tags to guide search engines

  • Follow URL best practices for long-term SEO benefits

By understanding and addressing ?m=1, you can keep your Blogger site mobile-friendly, SEO-safe, and visually clean.
