To modify your Facebook page layout, you can follow these steps:
Login to your Facebook account and navigate to your page.
Click on the "Settings" button located in the top-right corner of your page.
Select "Templates and Tabs" from the left-hand menu.
You will see a list of available templates that Facebook provides. Choose a template that best suits your page's purpose.
Once you have chosen a template, you can customize the tabs that appear on your page. Click on the "Settings" button next to each tab to make changes.
You can also rearrange the order of the tabs by dragging and dropping them into the desired order.
If you want to add a new tab, click on the "Add a Tab" button and select the tab you want to add from the list.
After making the desired changes, click on the "Save" button to apply the new layout to your Facebook page.
Note: Keep in mind that some templates may not allow you to customize certain aspects of your page, such as the cover photo or profile picture. In this case, you will need to choose a different template or stick with the default layout
