It is correctly said that never put your all eggs in one basket and same holds true for blogging earning potential. Bloggers consider Google as their main source of income through Adsense program sponsored by Google and if they get kicked by Google out of program for no fault of theirs than they are left high and dry.
Darren Rowse the famous blogger has stated that bloggers seeking to make money from blogging should spread their interests across multiple revenue streams so as not to put all their eggs in one basket and when he says one basket he just wants to say plain and simple and it is Google.
Thus as a thumb rule you should try for your readers as at the end of the day, they are your ultimate consumers and not search engines.
Social media be made a part of your strategy than do not go after it like a mad as selling them a product is like going to a party, meeting somebody for the first time, and then saying, ‘Hey, do you want to buy this Swiss Knife?’”
Thus one has to explore each means and apply 80 : 20 rule i.e. 20% of your effort gets you 80% of money and you must make sure that you get the best juice out of it.
