The Home Page layouts need to be configured in two places.
1. In Page Builder
2. Home Collection & its ranking 

It is a 1:1 mapping between a ranked 'Home Collection' in Bold against the layout in PB.

Example:
If you have 'Latest News' as the 1st 'ranked' in the home collection and a two-column six stories layout as the first layout in page builder, then the home page in the front end will display two column six stories layout with stories coming from the ‘Latest News’ collection. Likewise, the 2nd layout in the page builder takes stories from your 2nd 'ranked' in the home collection, and so on and so forth.

There are a total of 23 layouts that you can use on the home page/landing page.
Collection of the collection - This means when you use this layout, your corresponding mapping in 'Home Collection' should be a Collection and cannot just be a section.

Common settings for all the layouts: 

Layout settings: We can decide whether we want to display the section tag, author name, publish time, and time to read by checking/unchecking the respective box. 
 

Style settings: To determine the background color for the layout. The color can be chosen from the 8 primary colors for the website. 
 

Button settings: 

The ‘read more’ button can be customised to display any text of our choice. By default, the ‘read more’ button redirects to the section page that it is mapped to. Some layouts have the option of a subsequent load count which loads the subsequent stories in the section on the same page. 

To load additional stories upon clicking the "Read more" button, you need to input the "Initial Stories Load Count" and set the Button Property to "SubsequentLoadCount." Then, specify the number of stories to be loaded under "SubsequentLoadCount."
