I have blogs in Blogger.com, Bloglines.com and wordpress.com but just latest almost 2 or 3 days old. I want to know how can i get google ads. Any help highly appreciated.
Blogger usually allows you to just add your Publisher ID. If not, contact or implement them yourself.
Do you have an adsense account yet? If not then you will need to fill out an application and wait till next year sometime and hope you get approved. https://www.google.com/adsense/ When your site is a couple months old with a lot of content on it, your chances of getting approved by adsense is greater.
