Google AdPlanner now for everyone.

Google Ad Planner is available to anyone with a Google account, and the system has been given some useful improvements.

So what is Google Ad Planner? According to the original release post back in June, Ad Planner is:-
"a research and media planning tool that connects advertisers and publishers. When using Google Ad Planner, simply enter demographics and sites associated with your target audience, and the tool will return information about sites (both on and off the Google content network) that your audience is likely to visit."

There are three key enhancements to the service:

1. Improved Audience Definitions:
Define your audience by likeliness to search using particular keywords and drill down by state / metro geographical levels.

2. New Site Ranking Methods
Rank sites based their likelihood to attract your desired audience, the sites’ popularity or a mix of both.

3. Interactive Media Plan Analysis
A new interactive bubble chart allows you to compare sites in your media plan by demographics, frequency, traffic, and unique visitors.

If you're looking to expand your campaign, or checking that you're maximizing your potential coverage, this could be a very handy tool. It's especially useful that Ad Planner includes sites outside Google's content network which means you get a healthy view of the available online ad inventory.
