How to make an original title for every page post

Hi!
I bough "Baseball" theme and activated it.
How can I make an unique titel for every page (or post)? It's ridiculous to have one name for all posts and it not make any sense for SEO or any other work with searching engines.
Please help me to fix it!
Thank you!

Hi!
You can create a post and link the item of your menu only with it, not to add the whole category of posts. Besides you can simply create a page with its own title.
