blogspot and wordpress ranks in page 1 and page 2 and 3 in google for many keywords and search terms..
same goes for hubpages and squido pages .. they rank so high and often in page 1 2 of google for many keywords..
yahoo answers also ranks within page 2-3 of google as well
i would say dont waiste time creating a domain hosting and do link building seo submitting etc..
first get a big keyword list .. 500 for start
and build wordpress blogspot hubpages squido 1 by 1 (make keyword based subdomain).. link them each other
do some yahoo answers you tube comment posting filcker comment posting
digg them propeller them stumble exchange them in dp with other webmasters..
attach adsense in all ur blogspot wordpress squidoo n hubpages.. try moneytize with cpa also or any more you can think
because most of ur blogspot hubpages squidoo pages and wordpress authority subdomains are keyword based chances are they will rank well in google…
so if u get 10 visitor a day per keyword blog
with 500 blogspot blog u should get around 5000 visitors same goes for hubpages and squidoo and wordpress
but in practical not all keywords are available.. ppl have already taken most keyword based subdomains..
so expect around 10k visitors month max if you do can do all that..
but be sure you have chosen a high paying adsense niche and also a niche that has good amount of searches and interest of ppl
good luck..
lastly build a blog in ur own domain.. and get links from all ur
500 blogspot
500 wordpress
500 hubpages
500 squidoo pages
( you should get some good traffic to your main blog now)
