We use text tool to add text in muse website but we barely care about what tag we are adding text as. I mean the heading(h1, h2 etc.) or paragraph (p) tags. Even though it does not effect in design whether we are using the text as headline or paragraph, search engines like google does differentiate between headlines and paragraphs. We should add our headlines as heading and body texts as paragraph. This is not so hard in muse, simply click on the character panel from the right and from the very bottom of the panel you will find the option to change your text-box type from <p> or <h1>. This is really important for SEO.
