You asked for it, you got it! AdSense for Domains, which launched a year ago to help publishers earn revenue through ads placed on undeveloped domains, now uses optional keyword hints more often. These keywords are suggestions supplied to Google by domain owners about the types of content users are looking for when they arrive on an undeveloped domain. They are used to help our system determine the best ads to place on these domains. For example, with the domain, a publisher might suggest the keywords "bitumen" and "mining" so that ads may appear from advertisers offering oil extraction products.

Keyword hints remain optional. When keyword hints are provided by the publisher, our ad-matching systems will use them more often. As always, we aim to provide the most relevant ads for the user, the best value for advertisers, and the best returns for publishers. This means in some cases, keyword hints will be ignored when we have evidence that other targeting approaches perform better.

Instructions for setting keyword hints for your domains can be found here.

The AdSense for Domains team is continuing to work on additional product improvements, that we will be announcing in the coming months.
