Title and H2 Redundancy
Broadly speaking, headings and title structure help make your site accessible and your documents readable. They have other functions too, but these are their prime purpose.
The title should be an accurate statement of context; the h1 should clearly define what the page is about and the heading levels should assist all users as they determine the structure of your content.
When screen readers read a web page, they start by reading the page title then continue to read the body of the page. If your page title and first heading are the same, then the information is repeated unnecessarily.
