I have not yet used adwords. But i have thought of using it. I have a article site and I have been using adsense in it. Can i use adwords to bring more traffic which could be profitable one for me?
Yes you can but this is often called arbitrage. Google has been cracking down lately on arbitrage sites.
Yes, there has been a recent crackdown on MFA (Made For Adsense) websites recently. However, if your site adds real value to the user and is not made just to earn clicks for Adsense you might want to have a try at it. However, I would suggest that you do not put Adsense on destination pages, and that your adverts are highly targeted and relevant to the user query on the search-engine.
