Not all blog owners know the best ways to update labels, with the posts in their blog. We see occasional signs of confusion, in Blogger Help Forum: Learn More About Blogger . How do I add a label, to many posts at once? and How do I correct the spelling of my label, already added? and How do I remove all of the labels, from one of my posts? These owners are not aware how to use the dashboard Posts page - and Post Editor - to add, delete, and edit labels.
