How to change browser tab title

The url is island-adventure.com, the site itself is island-adventure.com/blog.

I need to change the browser tabs to reflect each page.

I added the SEO all in one pack and entered the title i wanted for the post and pages, but the browser tab is still saying island-adventure.com.

I’ve tried manually adding a <title> </title> tab to the page – no help.

any suggestions?

thanks in advance!
