[ASK] HTML for Title Blog in Home Page and Title Post?

I want to improve SEO on my blog. And i use blogger platform, by default the name of the blog will be in front of the posts but I can change it behind.
But i see a blog that has a different title in the Home page and the title in the post.
My question is, how to make the difference between the title of the blog while on the home page with the title of the post.

for example:
at Home Page ---> Dewa Inside | My experience, games, ect
at one of the post ---> How to Make FPS games Better | Dewa Inside

So, as we can see above, in the post only contains the title "Dewa Inside" while "My experience, games, ect" does not appear.
How to do it?
Please Help. :)
