Google Ad Review Center Can Block Politics, Sex and Religion

One of the problems with having third party advertisements on my web site is the embarrassment from inappropriate content. Google has introduced the "Google Ad Review Center", which allows publishers to block classes of AdSense advertisements from their pages. Rather than just provide a list of categories to block, Google reports how many times such ads have appeared on the publisher's web site and the proportion of overall revenue they provide. This useful, as it is apparent that many ads take up space on the page, without providing much revenue. These classes of ads make up almost 6% of those on my web pages, but only provide 4.6% of the revenue.

However, it creates interesting moral dilemma for the publisher, who has to decide if they can afford to give up revenue from ads they do not like. In my case I decided to ban everything except, drugs, politics and religion. The blocked ads made up 3% of those displayed, but only provided 0.4% of the revenue.
