I received a question from a new Adsense publisher this week, asking if it is a breach of Google’s terms of service to view your own Adsense pages. Of course you need to check your pages from time to time, although you need to take care NOT to click on your own Adsense Ads. When you view your pages using Internet Explorer you can also install the Google AdSense Preview Tool. This is an addition to the right-click menu for Windows Internet Explorer 6.x, allowing you to preview the ads that may show on any web page. I find this has limited use, it can help you find the URLs of Made For Adsense sites that you can list in your competitive ad. filter.
