Larger ad sizes tend to generate greater response

"Larger ad sizes tend to generate greater response. Size does matter apparently. As we have seen in years past, bigger ads perform better. We observed this with the latest set of metrics in which the half-page ad unit (300x600) which had the highest CTR, interaction rate (for both in-page and expandable formats) and expansion rates of all the available creative sizes we tracked for the benchmarks.
Although the U.S. had one of the lowest expansion rates, this market showed the highest expansion time. So Americans seem to expand ads less but when they do spend more time engaging with the ads themselves.
In terms of industry verticals, auto advertisers performed the best in terms of CTR (0.13% for flash ads) but conversely had the lowest interaction (1.9%) and expansion rates (0.2%). For interaction rate, telecom (9.4%) and B2B (9.2%) advertisers were the highest while B2B stood out in terms of expansion rate (7.5%) benchmarks."
