JuiceboxBuilder-Pro does not integrate directly with WordPress but you can certainly create a gallery using JuiceboxBuilder-Pro and then embed it in a WordPress page or post using the baseUrl method as documented here.
Essentially, once you have created a gallery with JuiceboxBuilder-Pro, you would upload the complete gallery folder (not just the contents) to your web server and paste the baseUrl embedding code into the body of your WordPress page or post (ensuring that the method of entry is 'Text' rather than 'Visual'). It does not matter where on your web server you upload your gallery folder to as long as the two paths in the embedding code (the path to the 'juicebox.js' file and the baseUrl itself, pointing towards the gallery folder) are correct.

If you select the 'Add SEO Content' checkbox (in the 'Customize -> Sharing') section, then the SEO code will be displayed as part of the embedding code that you would copy on the 'Publish' tab but, when pasting the code into your WordPress page or post, you might need to check that the paths to the images are correct (depending on the location of your gallery folder on your web server).

Alternatively, as a WordPress user, you might be interested in the dedicated Juicebox plugin for WordPress (WP-Juicebox).
Please see the plugin's support page for further details.
However, please note that the plugin does not include SEO functionality. This is a feature of JuiceboxBuilder-Pro only.
