Last night I attended the Vancouver Entrepreneur's Meetup at the Network Hub in downtown Vancouver. I met Tyler Wright the guest speaker. He asked me how to integrate his blog and his website together. Right now his blog is here: http://megawattpr.wordpress.com and his website is here: www.megawattpr.com
Here's the advice I gave him. Maybe you will find it helpful, too.
Tyler, you asked about how to combine your blog and your website. Well, the first
thing to would be to install Wordpress on your own web host account at megawattpr.com. This is recommended since you are now using wordpress.com for hosting your blog, Wordpress actually owns all your content and if by chance they shut down your account,you could loose all the posts you have.
Once you have Wordpress installed on your own website, I think you can port over the
content from your wordpress.com account. (I need to check on this and find out the details.)
You can add pages to your blog like About Us, Home, Contact page and the blog would
be one of your pages or you can have the blog feed come up on your home page if you like. You can have your wordpress site custom designed so everything matches.
About Google Analytics, I will look into it for you. I'm thinking they track the statistics per domain name so I'm not sure you could keep all your old statistics to continue on with the new website. But this I'm not sure about. I will get back to you with more information.
I hope you found this helpful. Let me know if you have any more questions.
