Hi,i would like to know how i could attach a google adword ad to a article on my website without letting the visitor knowing that when he click the article that he's clickinga ad,any help?
What your doing is most likely against the Adsense TOS. Or maybe you just want to blend the ad really well. If that latter is the case just change the text to match the background of your site.
There's really no way to hide a Google Adword ad...you can blend it into your site by changing the link and text colors and getting rid of the border around the ad unit...but it'll still say "Ads by Google"
