DIFFERENCE BETWEEN TITLE AND PAGE TITLE
Difference between Title and Page Title is:
The Title field contains the name of the content block and becomes part of the url or path to the content while the Page Title is the title displayed in all capital letters at the top of each page.
What is the Title Field?
The field entitled 'Title' is the content block name and becomes part of the url or path to the page. If you change this title you break every link to the page.
What is the Page Title Field?
The Page Title (second field in most smart forms) is the level 1 heading on the page and can be changed as often as you want without breaking any links. Every page must have a level 1 heading and a page title to meet accessibility requirements.
