I'm a little bit new but I know some tricks :
You can put this into your <head> :
<metaname="description" content="Your description" />
<metaname="keywords" content="your keywords " />
And in Edge Animate, when you select a text and go into the properties panel, you can specify if it is a H1, H2 etc....
And finally when you publish your project, it's better to publish it as a static html file. So that your DIVS and stuff will appear !
But i'm sure there are lots of more stuffs !
Waiting to hear for the pros ;D
