i want to know whether is there any such way in which we can get the google ads directly on our blog like without doing stuff like copying and pasting the codes pls explain this to me guys
At the very least you'll need to paste your goggle id over. There are some plugins that help to serve ad's depending on which CMS software you use for your blog. Do you use wordpress? If you do check the post over at: http://forums.digitalpoint.com/showthread.php?t=947875 . Under the plugins section of the post there is an adsense manager plugin that might take care of your needs.
