To add a new page, navigate to My Site(s), then click Add next to Pages:
You’ll land on the Editor, where you can add text, media, embeds, contact forms, or any other content for your page. Customize, review, save, or publish your new page using the editor settings.
Edit a Page
If you would like to edit an existing page, head to My Site(s) then click Pages on the left menu. Next to the page you’d like to edit, select Edit from the dropdown.
Setting a “Home” Page
By default the front page of new WordPress.com sites will display posts from your blog. If you would like to create a more traditional website, add a page called “Home” and add any content you want to display. Next, head to Customize in My Site(s) and select Homepage Settings. Choose your new “Home” page as the front page for your site.
