What is difference between adwords and adsense? Im new in this ,witch one i should ad to my website . thanks in advance
Adsense and Adwords are Google's services for publishers and advertisers (respectively). Adsense is good if you want to make money by placing ads on your website. (Google pays you) Adwords is good if you want to get more traffic to your website. (You pay google)
Both are Google's programs as you know and if you can afford to avoid them by earning enough from your own advertisers just do it.
if you want to earn money by placing ads on your website. adsense is yours. google pay you when your visitors click on it. If you are selling something and you want targeted traffic to your product. adword is for you. you can also use adword only for traffic rather then selling products. after you signup for adword, your ads will be shown on other sites (who are adsense publishers) on internet and you have to pay to google when someone click on it.
