Google is taking help from us, by displaying these Ads on our websites, rest of the game is simple; visitor visits your website, where Ads are displayed by Google, when they click on it, Google will get money from those Advertisers. Now this all happened or took place just because of your website, means you are helping Google in Promoting the Ads. Google will not make you upset, for every Ad that is clicked on your website Google will pay your commission for each click which ranges from $ 0.10 To $ 5 ( Rs. 5 to Rs. 200 ) .
The quality of back links or referring links to your website from the external websites should be extremely high. If the quality is not good then the website can be penalized by Google. I have hired the most appropriate seo company for the back links work. They are working amazingly.
