I'm a newbie to advertising and I just published my new little website removed. I have adsense and I want to know how to make best use of it. How to get really good good high quality advertising from it on my site. Is there any way I can kind of help assure the appropriate ads are placed on my site? Like holiday shopping, decorating--Kmart, Macys, Kohls, JC Penney, Christmas Depot, large Christmas tree farms, wreath producers, -I make a lot of holiday and seasonal wallpapers. Also charities like Save the Children, Red Cross, etc. Because Just Too Cute promotes Charities.

What I'm concerned about, is that I'm trying to create a Desktop Wallpaper site that is tasteful, and high quality, and doesn't have the cheap stuff I see on the other wallpaper sites. The flashy, tacky, advertising, the spyware, and secret adware and malware that you download without being aware. I want people to come to my site and know their computers are safe and they are getting a nice clean tasteful product and can enjoy a pleasant site. I know that what I have is definitely NOT everyone's cut of tea, but many do like my creations.

To tell you the truth when I go on a site and I see ads for macys and other large companies, I feel "well if they trust this website owner enough to do business with them, I guess they might be ok." If I see ads for ads that are for sites I know are trashy, I leave with smoke on my heels.

So, how can I get what I'm looking for from Adsense? Or can I?

Adsense requires words on the page to display appropriate adverts.

I just signed up and I haven't put it on yet,

So put them now if your application has been approved. Through that way, you can test what are the Advertisers that are displayed in your pages. If you are not satisfied with the Ads being displayed in your site, do as what @chrishirst said. Edit your content and give more emphasis on the kind of Advertiser you want to appear in your site.
