Shortcodes cause incompatibilities when using Yoast

This plugin is great! Thanks for all your efforts.

I did notice an issue though. The shortcodes in this plugin cause incompatibilities when using Yoast, because the shortcodes are echoing content instead of returning content. (See this relevant github issue)

I was able to workaround this by adding ob_start(); and return ob_get_clean(); to all of the shortcode functions in this plugin, but please consider updating the plugin to fix this issue for others.
