Action Details
Requirements and how-to articles for Google My Business's action:

With Google My Business, you can create a simple but free website to represent your business. (Note: There is no option to edit metadata or add social media sharing buttons, and the customisation options are very limited.)

Requirements
You need this to get it done:

Google My Business Profile
You must have a Google My Business profile in order to create a free website. Information about your business such as its name, category and opening hours are automatically filled in on your website as they are pulled from your My Business profile.
Website URL
Choose the URL for your website. It will begin with "http://" and end with ".business.site" (if you wish, you can purchase a custom domain from Google Domains.)
Choose Website Theme
Choose one of the available visual themes for your website, each with different colours and fonts. This is currently the limit of how much you can customise the appearance of your website.
Headline
Attract customers with a headline (maximum of 80 characters.) By default, this is the name of your business. However, the name of your business is already at the top of the page, so it's recommended to instead use this space for something else, such as a tagline for your business.
Description
Describe your business in one line (maximum of 140 characters.) By default, this is your business category and location.
Summary Header
Personalise the header for your summary section (maximum of 40 characters.)
Summary Body
Write the main summary body of your website using a WYSIWYG editor. Use this to showcase your business and/or products. If you have a main website for your business, you can add a link to it here to help boost its SEO ranking.
Available formatting: Bold, Italic, Underline, Link, Ordered List, Un-ordered List
Gallery Image(s)
You can upload images to be displayed below the summary body. Images will be displayed as tiles, with the most recently uploaded image as the largest tile. The photo(s) should be in focus and well lit, and have no significant alterations or excessive use of filters. In other words, the image should represent reality. (Note: There is no option to crop or otherwise edit images as they are uploaded straight onto your website as they are.)
File format: .jpg/.png
File size: Between 10KB and 5MB

Cover Photo
A photo to represent your business. Adding a cover photo automatically sets it as your listing’s preferred photo. The photo should be in focus and well lit, and have no significant alterations or excessive use of filters. In other words, the image should represent reality.
File format: .jpg/.png
File size: Between 10KB and 5MB
Minimum resolution: 720 x 720 pixels
Services

Each service has the following text fields:
Item name (maximum of 140 characters.)
Item price (optional.)
Item description (maximum of 1000 characters.)
Primary Button
The following call-to-action buttons are available: "Get directions", "Call now", "View menu", "Find table", "Place order", "Make appointment", "Message us (SMS)", "Message us (Whatsapp)" and "Get quote."
