My Keyword is not in the Title Tags

Hi, I have put my keyword in the title box under Settings; General; Site title, but I have just looked at view-source:http//www. etc and it shows that there is nothing between the title tags. How do I insert that?
I am using Arras theme
Cheers

Just install a seo wp plugins, should be easier for you to manage on page seo.

 

Thank you, I've got Head space but not configured it, Overlooked the obvious!
