The first step is to choose a name for your site, which will tell visitors what your site is about.
Once you decide on the perfect name, select your site and choose “Settings” from the navigation menu on the left-hand side.
Enter your site title, then add a tagline to explain what your site is about.
You can also upload or select a site icon, which you’ll see in browser tabs or bookmarks in your web browser.
When you create a site on WordPress.com, you’ll automatically have a site address that includes your site’s name dot WordPress dot com. But you can add a custom site address if you prefer. WordPress dot com will suggest a list of domain names that are available based on the site name you choose. You can search for a different domain name or choose from the list of domains below. Best of all, your domain is free for the first year with any WordPress.com plan.

The first setting you will see is Site Title. The Site Title is displayed in the title bar of a web browser and is displayed in the header for most themes. Your Site Title will also appear in the following locations:
- My Sites on your WordPress.com dashboard
- The sender’s name when your followers receive notifications
Site title can be anything you’d like to describe your site. It doesn’t have to be the same as your site’s URL or your username. You can use a cleaned-up version of your URL (e.g., myawesomesite07 can become My Awesome Site), or change it to whatever best reflects your site’s personality and topic.
Note: Changing your site title does not change your site address or your domain.

The tagline is a short description or catchy phrase to describe what your site is about. Some themes will display the tagline in the header or in the sidebar.

The Site Icon is used as a browser and app icon for your site. It is the tiny image that you see next to the site title on the browser tab:

To change the site icon, upload a square image that is at least 512 × 512 pixels:

The Site address allows you to select a custom domain to use at your website. You can use a domain you already own (by connecting it), register a new domain or transfer a domain you already own to us. You can also create a Site Redirect.

The Language option lets you select the language to use for some of the theme text shown to your site visitors. If you select an RTL language (for example, Hebrew), then the theme’s layout will mirror itself so that the text can be read properly from right to left.

Your site’s timezone is set to Coordinated Universal Time, UTC by default, which is in London, UK. If you live in a different area of the world you will likely want to change this option. The current UTC time is listed to the right to make it easier to determine your timezone offset. As an example, when Daylight Saving Time is not going on, Boston, MA would be UTC-5.

More details about these settings can be found on the Privacy Settings support page.
You can change the Footer credit of your website. Learn more about the Footer Credit Options.
