So you are saying, we won't get money for page visits??????
Sandhya you can certainly make good money by writing recipes as recipes are the new emerging market.
And what sarala said is true but things are changing. Many offline food chains are coming online and so the ads are becoming more relevant and people actually click on the ad.
One thing you must realize is that for a casual surfer, there is no such thing as ads. Everything on your site is a part of your site and it is upto you where you want to send your users.
But let me tell you one thing very honestly, you would never be able to get much traffic to your recipe as you are starting on a free blogger blog. For recipe blogs, google take into account other meta data like user reviews, time to prepare the meal, nutrition value etc etc. Here is an example of that:
http://www.google.com/#hl=en&gs_nf=1&cp=15&gs_id=1l&xhr=t&q=chocolate+cake+recipe&pf=p&output=search&sclient=psy-ab&oq=chocolate+cakw+&aq=0s&aqi=g-s4&aql=&gs_l=&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&fp=cfdef316585c5ae0&biw=1920&bih=979
Look at the first result, you will see stars rating, how many reviews and time for preparing the meal all in one line. You can't do it with free blogger blog.
You need to have your own site to implement the metadata script.
