I have designed an web page through blogspot.can i earn through it.is possible r nt.
You can obviously earn if your site has a good traffic and content. Just remember "Content is king." You can use ad networks like Adsense or Adbrite to display advertisements.
U think there is a chance to increase the site hits.
Yes, by promoting it and having good results in Google's search engine.
A top level domain would be better. You can get one free from Indiagetonline.com
