I've got a site that is pretty established. It was built using Xsitepro (html). There are some inner pages indexed and ranked on Google as well. I'm thinking to build out the site and make it bigger... I'm not sure if it will help better in ranking if I change to wordpress? But I've already got pages indexed so if I change to WP then it will probably affect the site/rankings.
What do you think? Anyone using Xsitepro have experience with building authority sites with it? Any success?
