Step-by-step: how to show post titles only on the homepage

To display only the post titles on your Blogger homepage instead of the full posts, you can follow these steps:

Sign in to your Blogger account and navigate to your blog's dashboard.

From the left menu, click on "Layout."

Locate the "Blog Posts" widget on the layout editor. It is usually found in the main column or in the "Blog Posts" section.

Click on the pencil/edit icon on the widget to edit its settings.

In the configuration options, look for the "Post content" or "Content to display" setting.

By default, it might be set to "Full posts." Change this option to "Titles only."

Save the changes to update the widget settings.

Once you have completed these steps, your blog's homepage will display only the post titles instead of the full posts. Visitors will need to click on the post titles to view the complete post content on a separate page.

Remember to preview your blog after making these changes to ensure that the post titles are displaying as desired.
