To change the logo or site title in WordPress and customize the branding of your website, you can follow these steps:

1. Log in to your WordPress admin dashboard. Typically, you can access it by appending “/wp-admin” to your website’s URL (e.g., “http://www.yourwebsite.com/wp-admin“).
2. Once logged in, navigate to the “Appearance” section in the left-hand menu and click on “Customize.” This will launch the WordPress theme customizer.
3. In the theme customizer, you will find various options to modify the appearance of your website. The specific options and their organization may vary depending on your active theme. Look for options related to site identity, branding, or header.
4. To change the site title, look for an option that allows you to edit the “Site Title” or “Site Identity.” It may be located under the “Site Identity” section or a similar label. Enter the desired title for your website.
5. To change the logo, look for an option that allows you to upload or select a new logo. This option might be labeled as “Logo,” “Site Logo,” “Header Logo,” or similar. Click on the logo option and either upload your logo image from your computer or select it from the media library.
6. Depending on your theme and customization options, you may have additional settings to adjust the logo’s position, size, or other visual aspects. Explore the available options to fine-tune the branding to your liking.
7. After making the desired changes to the site title and logo, click on the “Publish” or “Save & Publish” button to save your changes.
8. Visit your website’s front end (view your website as a visitor) to see the updated site title and logo reflecting your customization.
