Lets say you have food site called ( im making this up ) jumpit.com
The home page of Jumpit.com is targeted at the keyword "Restaurants" and is getting first page ranking on google.
Then you have sub pages for different cities such as jumpit.com/chicagorestaurants.php that are also getting first page rankings for the key word "chicago restaurants".
Now my question is, most of the site is targeted for the keyword "restaurants" and now I want to target a new keyword such as "beer", so if i create a page such as jumpit.com/beer.php , is it possible to achieve ranking in the keyword "beer" ? Obviously with on and off site seo.
