What is Google AdSense?
AdSense is an advertising program offered by Google, it allows you to easily add Ads by Google anywhere onto your website. AdSense is a great way for many Website Owners to generate a constant passive income from their website. AdSense displays ads on your website that are related to the content on that page, this makes visitors more likely to click on those ads.
How much does it cost and how much can you make?
The great thing about AdSense is "It's Free", you never have to pay anything to use it, and you can only make money with AdSense. Should you use AdSense?
Personally I think most content websites should use AdSense as it is a passive income and easy money. On the other hand for those of you that are making sites to sell products should probably steer away from adding AdSense to their sales pages, that's just greedy and you will find you get less sales of your actual product. I'd say it's ok to put AdSense on other pages that you have decent content on but not on sales pages, also Google doesn't like their ads being placed on pages with little or no content. If someone was to click on an ad on your sales page then you are sending your potential buyers to other sites to buy something.
Potential of AdSense
First I would like to say that not everyone will make much money with AdSense and again it depends heavily on how much Traffic you get. With that said AdSense can earn some people a lot of money, a very small amount of people have been able to earn tens of thousands of rands every month from AdSense. However the average high earner is capable of earning thousands a month.
Just remember to work hard on your website, provide killer content and drive your traffic crazy and you will earn your fair share of Google AdSense.
