Page Template Settings
Page Template Settings set the page layout and other page options for a whole type of page, for example all search results or all author archives. Go to AppearanceCustomizePage Template Settings.

Sections
The panel has one section for each type of page:
- Blog Page
- Search Results
- Date Archives
- Author Archives
- Not Found, the 404 page
- Type sections, one for each public post type that has an archive. For example: Type: Products with WooCommerce.
- Taxonomy sections, one for each public taxonomy that visitors can view on the front end. For example: Taxonomy: Categories and Taxonomy: Tags.
Settings
Every section has the same settings as Page Settings, except Page Featured Image. See that page for what each one does. The Blog Page section starts with the page title off. All other sections use the same defaults as Page Settings.
Click Publish to save. The preview refreshes after you change a setting.
Page Template Settings apply to every page of a type. To change one page or post, use Page Settings.
