Google is making changes to DoubleClick AdPlanner that will restrict the data it provides. On September 5th, you will no longer be able to research domains that are not part of the Google Display Network (more money for Google I guess). They have gone even further to remove demographic data ,such as, keywords searched for, videos also watched, house hold income and education.
Google seems to be clawing back more and more web data every day. Have you noticed that the number of undefined keywords (eg, not set or not provided) in your Google Analytics account is growing each day? Well this is all part of trend toward restricting data on the internet…
For better or worse it will be harder to tracking online marketing in the future. This should be a call to action to build your data now, while you still have access to it.
