How to change title dynamically?

I’m looking for the same answer! Hopefully there’s someone out there that could help us!

All in one SEO plugin allows you to choose the page title of any individual page. Not sure if this is what you’re looking for.

<title><?php wp_title('|', true, 'right'); ?> <?php if (get_query_var('paged')) { echo get_query_var('paged') . ' page'; } ?> <?php bloginfo('name'); ?></title>

Where do you insert this code?
