when you get a blogspot blog....you get a new domain anyway and it still has to go through this myth called the "sandbox" If you got a site top rank for a keyword without any inbound links....then a) no one is searching for that keyword b) no one cares about that keyword c)no one is targeting that keyword d)no one is wasting valueable time and money optimizing for that keyword. e) when you search and it says 1 to 10 of 1000000, that not a true indicator of the competition of a keyword
I use blogspot, and I earn money form it.. but i would rather buying domain, because it's easier to optimize to search engine
I too think of the same thing? how can you do seo for blogs and that too for free blogs? if the blog is not optimized then how will one make the blog appear at top in the google?
