Most small business sites need between three and six pages. Home, about, services, contact is a complete site for a lot of trades. More pages is not better: a visitor who has to choose between nine menu items usually chooses none of them.
The page you add inherits your colours, fonts and menu automatically, so it will look like the rest of your site before you have typed a word. What it will not do is appear in your menu until you put it there, which is the step people miss.
Step by step
In the editor, open the page menu at the top.
Press Add a page and give it a name, like Services.
Name it what a customer would call it. Services, not Offerings. Contact, not Enquiries.
Edit it exactly like any other page.
Add it to your menu so people can find it.
Publish.
If it does not go to plan
The page exists but nobody can reach it.
It is not in the menu yet. Open the menu settings and add it there.
Can I delete a page?
Yes, from the same page menu. If it has been live for a while, tell us before you delete it and we will make sure links to it do not break.
