Ok, I know everyone on here loves wordpress, but how much of a difference in ranking would I see if I used WP vs. Xsite Pro for a couple large authority sites? My mid size and mini sites rank just fine with Xsite pro right now. Also, I should mention that an additional 2-3 sites are going to be service type sites where I will be selling subscription-based packages. *Please note that I do not have any experience with WP as of right now. Will this make that much of a difference? Will it be hard to sell a WP site if I decide to in the future? I have heard moving the "databases" never works out well when selling. Thank you!!!!
