After including Adsense in the sidebar (signature) of my page, I have received many feedback saying that Adsense is making my web site look like a spamming page. Should I remove all Ads from my pages? I was also advised to remove Amazon books!
Depends on what you want with your site. I dont think it looks spammy now, but if you want to maintain a directory with credibility you could choose for other options of earning. Its all to you. But it doesnt look spammy now because of one ad. perhaps that you could remove the ad from the frontpage and only display in categories to keep you clients happy.
