WPMU Manuals on Multisite question

Hi,
Just in relation to your manuals
https://premium.wpmudev.org/manuals/wordpress-multisite/
The multisite manual says it will cover topics on
- WordPress Search Engine Optimization (SEO)
- Making Money with WordPress Multisite
I couldn't find these two area's in the manual. Are you able to flick me a link to them, or support articles on these topics.

Thanks.
