Should I remove this for a better SEO in Blogger blog?
If you want to remove the "/?m=1" part from a Blogspot (Blogger) blog's URL, you can follow these steps:
1. Log in to your Blogger account.
2. In the Blogger dashboard, select the blog for which you want to make this change.
3. In the left sidebar, click on "Settings."
4. Under the "Settings" menu, click on "Search preferences."
5. Look for the "Errors and Redirections" section and find the "Custom Redirects" option.
6. Click on "Edit" next to "Custom Redirects."
7. In the "From" field, enter "/?m=1" without quotes.
8. In the "To" field, leave it empty or enter the URL you want to redirect to without the "/?m=1" part.
9. Save your changes.
This will set up a custom redirect so that when someone accesses a URL with "/?m=1," they will be automatically redirected to the URL without that part.
Remember that making changes to your blog's URL structure might impact SEO and existing links, so use this option with caution and ensure it aligns with your overall website strategy.
