Is having more data ever a bad thing? Advertisers and publishers have asked themselves this question since the June 2008 launch of two new Google tools. The first, Trends for Websites, is an extension of Google Trends. Like similar tools from Compete, Alexa, and QuantCast, it allows you to research Internet traffic volume for one or more URLs. Google Trends provided search volumes by keyword only, but this tool calculates a site’s audience via a combination of sources, “such as aggregated Google search data, aggregated opt-in anonymous Google Analytics data, opt-in consumer panel data, and other third-party market research” (Trends for Websites Help Page).
But the revamped Trends tool is only a small fragment of the real story – the launch of Ad Planner, a free tool to help advertisers identify the most relevant websites (publishers) to buy online ads from to reach their target audiences. Ad Planner provides details on a domain’s traffic volume, audience demographics, and competitors.
