that is probably true. The only reason I consider adding more ads is because I think most of my traffic is likely to be repeat visitors. So I imagine even if they do find the ads interesting, if they are seeing the same small number of ads, that they will be even less likely to click on them in the future. With additional ads they probably will still see repeats but at least they will have more choices.
yes, I've given my ads a color scheme that goes with my site. I would show you the site, however I am under the impression it violates a rule here, since I am a newbie?
