Google Adsense Creating Ads

[novak]

Hello guys,

I'm really new in adsense and E marketing itself so i might need some of your help or re directions. I created site recently and implemented ads on my website but when i check back some ads still shows blank, some shows as ad. Cant understand why? Also when i checked my adsense today i saw in my ads tab there are plenty of ads what i did not create and don't understand what's going on? How those ads were created itself or what exactly they mean? Also want to understand what is a exact meaning of new and active ads? For example if i want to re-implement ad should i take new code from existing and active ad or from new (in status bar) Can any one explain me how exactly ads creation works and how to implement them correctly on the website? or just link me a tread if it was already discussed.

Thanks in advance
