Edit what your website says
Open Menu, then WEBSITE, then My website. The content controls are grouped into Design, Page blocks, Content, Hero images, and Announcement banner.
Content holds the words that describe you: Headline, Tagline / about, Your bio, City / service area, Year founded, plus a Pull quote and an Opening line. Each field has an example in gray showing the kind of thing that works.
Page blocks are the stackable sections down the page. Each block takes a Section heading, a Body paragraph, and an optional Caption. If it says "No sections yet. Add one below", you have not added any.
Announcement banner is the strip for something time limited, like taking bookings for a season. It has Banner text and a "Show banner on my site" switch, so you can write it once and turn it on and off.
Two things that catch people out. Your public contact email and phone each have their own "Show my email" and "Show my phone number" switch, and nothing appears on the site until you both fill the field and turn the switch on. The app says so directly: "Add an email above. Nothing shows on your site until you do."
Remember to publish. Editing alone does not change the live site.
