If you want a certain node (page, article, event, etc.) to be visible on the front page of your site, you must promote it to the front page using the editing options at the bottom of the creation screen.
1. If you have not yet created the page you wish to promote, click 'Add content' and select the type of content you would like to create. If you have already created the page you want to promote, find it on your site and click 'Edit.'
2. You should be directed to the editing screen. Scroll down to the bottom and select 'Publishing Options.'
3. To the right, select the 'Promoted to Front Page' checkbox.
4. Click 'Save' at the bottom.'
Your content should now be visible on the home page of your site.
