Making good on an earlier promise, Google has begun rolling out a new Landing Pages tool. It's a tab in AdWords that can help developers see how their landing pages are performing, with mobile clicks broken out from other clicks. It could help Web developers identify landing pages that might be loading slowly on mobile devices, leading to a slow click-through rate.
For now, mobile Landing Pages data is only available for Google Search ad campaigns, but general data is available for display and video campaigns as well.
