Every business including blogging business need to analyze the ROI (Return of Investment), that is, how much effort you are applying and how much profit you are making in return. You are writing blogs spending lots of time, doing SEO campaign for high Google ranking, applying marketing strategies to grab traffic but your earning makes you disappointed. Why this happens: Yeah, one of the main reason is your keywords are low paying. You are getting huge visitors, they are making clicks but the thing is clicks are making few cents. I found that CPC (Cost per click) varies for different keywords within the same niche. Few days ago I was thinking to start a new blog on the niche Swine flue. While researching keyword with Adword keyword tool I found some good keyword with high search value but their CPC (Cost per click ) is too much low only $.05. Again I was going through the CPC column and found 2 keywords with CPC $2.45. Although CPC $2.45 doesnt refer that its a high paying niche but comparatively its higher than other keywords on the niche Swine flue . So it is wise to start blog on the keyword with CPC $2.45. Actually CPC is not the actual amount that you will get per click. This tool is designed for Adwords clients to help them figure out what the average price per click it will cost them to run ads in that niche, but fortunately you can use it for your own advantage. Thing is if CPC is higher for any keyword then PPC (pay per click) will also higher for that keyword. So, from the CPC you can assume that which keyword will return you more profit in blogging business.
