Rontar Ad Exchange: Free Ads

We've been trialling the free retargeting plan for about a week. Hard to tell if its a coincidence, but had our best week ever, and around 30% increase in visitors. We're definitely getting good referrals coming through, and keen to see how it continues to perform over the coming weeks.
We would prefer a snazzier looking ad, but it's working.
So far, we're impressed, and it's free!
