Post your presentation in a blog with Keynote on Mac
You can post a presentation on Medium or WordPress so that readers can click through the presentation (without its animations and interactive elements), using a player in the blog. Any changes you make to the presentation in Keynote are automatically reflected in the embedded version.
To see the full version of the presentation, readers can open it in Keynote where they can also edit it, if you set sharing permissions to allow editing (rather than viewing only). In this case, any changes made by viewers are also reflected in the embedded presentation.
To include an interactive presentation in a blog post, you need to share the presentation, then add a link to it in your post.

Who can access: Click the first pop-up menu and select “Anyone with the link”.
Permission: Click the second pop-up menu and select “View only” if you don’t want the people you’re sharing with to be able to change the presentation; otherwise, select “Can make changes”.
Note: Don’t add a password. (If you do, the link you embed won’t work.)
Do one of the following:
If the presentation isn’t already shared: Click Copy Link, then click the Share
button.When the Starting Collaboration message closes, the link to your presentation has been copied to your clipboard.
