I have a main page A with 5 main categories. I use H1 tag for my website title displayed on main page and on these 5 main categories. On a second page B i have the 10 subcategories for each main category,
1.For subcategories on B page should i use H2 tag or H1 too(because it is a new page)?
2.Except page A ,i can use H1 in other pages on my site,for important titles,for example?
3.It is ok to use H1 for title and for 5 main categories too?
