Hi all, I have a website and I am planning to re-launch it with a new look. The site offers various web design and development services along with content writing, graphics design and Flash animations services. In my newer version site, I am only going to focus two main services; 1) Web Design & Development and 2) SEO/Internet Marketing. So, the thing confusing me is: Current site is already optimized and have keywords in titles and content. But as the newer version will have more pages about web design and SEO, so would it be O.K. to add and CHANGE/REPLACE previous keywords (those keywords aren't bringing any reasonable traffic at all though)? Please guide me about it as I am a bit confused... Thanks
