I have noticed that blogs made on blogger are indexed faster by Google that Wordpress blog. Is it so?
I've not really seen much of a difference. Wordpress also has a pinging system in place. Your posts should get indexed fast.
Ya thats true!! blogger getting indexed soon!! and also a New Domain will be ranked only after 3 months! but a blog will be ranked immediately!!
Blogger is faster as it's owned by Google. I have one blog which I haven't submitted to Google and still got indexed very quick.
My blogger blog had complitely indexed in 1-2 week but my wp blog havent yet although 1 month . but I wonder if I change subdomain to a top level domain, does same things happen???
The subdomain does make a difference, but not a huge one. If you have people linking to the main site, and then clicking through to the subdomain though, that will cause your outside marketing efforts to affect only the main domain... becomes like 2 different sites that way as far as indexing and Google PR goes...
Yeah sure Blogger Blog's get's indexed fast since it's owned by google... As far i know Google gives importance to it's product first mate... For example i searched a keyword Blog Google results as shown below http://lmgtfy.co.cc/?q=blog
