To prevent all search engines that support the meta tag from using ODP information (Google’s words, not mine), use the following:
<META NAME=”ROBOTS” CONTENT=”NOODP”>
This is a welcome addition, as Google’s methodology for the inclusion of this data has appeared inconsistent. Of course, Google’s appetite for your pages will determine how quickly they will change, if you are suffering from this condition. If you are not, do it anyway. That’s all you need to know for now, so off you go, get on with it!
