Wordpress is handy when you want to use certain plugins.
However, there is a lot of updating going on with wordpress,
and not all plugins are updated at the same time.
I have sites that I did not look at for two years, done with XSitePro,
and they are still fine.
Wordpress wants your attention more often.
XSitepro goes a bit slower in the searchengines, but with the right keywords
and strategic backlinking you surely can climb your way up.
Once it's there it can stay there completely handsfree.
All in all I like the simplicity of XSitePro.
Integration of wordpress and XSitePro is not difficult, but it is timeconsuming
and extra work.
Why would you want to do that?
There is a slight advantage using wordpress when you launch a new blog,
but easy does it in my opinion.
You have to make a choice, because there are sooo many options.
You don't need 100 ways to get traffic to your site, but 1 or 2 and then stick to that.
That's how you get to the top in the searchengines.
All the best!
