The downside about having so many sites, up to 22 right now is you have them spread over so many hosts. Keeping some sites on their own C block addresses are helpful to add links to my other sites in my network. However the big problems is you have to deal with so many different hosting panels or cpanels.
So this week I single handedly moved 14 sites over to Hostgator which I just love for the fact that I can have an unlimited number of domains and a large number of databases. Plus some of my sites where coded up in hard HTML and I really wanted to port them over to wordpress.
I was spending about $65 per month to host come sites on Godaddy through a number of plans and I just got tired of having to keep track of them all. As of now I have these sites on two business hosting accounts that I can add more sites as I grow. The other benefit hostgator uses a slick cpanel interface making it a snap to run my business.
I still hold my domains at Godaddy but I just had too many hassles at Godaddy for hosting.
WordPress
Since most of my sites where hard coded years ago in HTML I switched everything over to WordPress so that it makes it easier to manage my content on all the pages. The only thing I had to do was to redirect the old pages to the new wordpress pages. I use what is called a 301 redirect which tells google and other search engines that the page has moved permantely to the new wordpress page. It’s done through the .htaccess file located in the root of the your site. Once you do that then you can efficiently add more content to your site without the hassle of modifying pages throughout your site.
