Google announced today that AdSense for Domains is now using optional keyword hints more often. Keyword hints are provided by the user, who enters keywords into a field to assist Google in the targeting of ads for potentially ambiguous domains. Google’s Randy Heath explains:
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 www.rockstarsand.com, 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.
Keyword hints have to adhere to Google’s policy guidelines for AdSense for Domains. The company also recommends the following guidelines to maximize effectiveness:
– Limit your keywords to 3-5 phrases
– Ensure your keywords/phrases are separated by commas
– Ensure your hints are relevant to the domain
– Stick to one theme for potentially ambiguous domains.
Google says it is working on additional product improvements for AdSense for Domains, and these will be announced in the coming months.
