You must have seen that when you add a label widget in Blogger, it’s showing the number of posts each label contains. Well, you may don’t want to show it. To hide the number of posts showing per label in Blogger, you have to enable some settings and to do that you need not to edit your template for it.
Go to Design > Page elements tab and click the edit button under the label widget. Now uncheck the “Show number of posts per label” and save it. View your blog and you will find that the number that is shown beside each label is gone.
