When using the keyword tool from google I have found niche areas that had keywords with a CPC of 7-9$ is this good? I am thinking of creating a keyword rich site with adsense and do not want to waste my time if this is not a good cost per click.
thats good but just make sure you will targer U.S visitors/customers. beacause Asia traffic dont pay well on adsense..good luck mate
High pay niche normally have more competitor, it is good if you are expert on SEO and able to input great content.
