I have a blog hosted by blogger and now i want to register my own domain name.If i have to run adsense in wordpress blogs i have to pay them $900 per month under their VIP hosting plan. should i stay with blogger even after registering my own domain or should i choose any other blog host than wordpress...? I like to change to wordpress but what about cost,or i should miss adsense or any other ad
Choose a different host. You need not host on wordpress at all. also post on blogger stating that you have moved to a new domain and would continue posting from there. That would help regain visitors. Wordpress is compatible with a majority of hosts so you can safely select a host with whom you are comfortable with.
I couldn't emphasize what ARonald said more strongly. That $900 fee is absurdly high, and you can use Wordpress for free on other hosts, and simply place the AdSense code inside your presentation template.
wordpress is free to download, so just download and host it somewhere like hostmonster.com ($5.95 / month)
The details are here http://wordpress.com/vip-hosting/ What they ask is $600 for a one time setup fee and $300 a month hosting. Not worth unless one gets a lot of pageviews.
