Those who often make use of AdWords' free Conversion Tracking tool and have at least 30 conversions in the last 30 days can use Conversion Optimizer in Adwords now.
"We're also happy to announce that the Conversion Optimizer is now available to all campaigns using AdWords' free Conversion Tracking tool that also have at least 30 conversions in the last 30 days. So, if you were previously unable to use the Conversion Optimizer in AdWords, you may now be eligible to use it."
The tool makes use of the conversion tracking data in order to optimize ad placement based on the likelihood of conversion, so that users can gain more expertise and effectiveness by saving a lot of time.
"You might already adjust your keyword bids with the goal of increasing your conversions or decreasing your costs, but the Conversion Optimizer is able to adjust bids using additional factors that are otherwise unavailable."
"This includes varying bids by broad match query, user location, and the particular search or content partner sites where the ad is appearing. These extra adjustments enable many advertisers to achieve double-digit percentage increases in conversions while paying the same price or less for each conversion," wrote Amanda Kelly on the Inside AdWords blog.
