A year after successfully implementing sentence compression algorithms in Google Search for desktops, it appears the company's machine-learning system has matured to assist mobile advertisers in condensing information for Google AdWords.
At the end of August, Google will roll out more options for mobile advertisers on AdWords with the aim of improving clickthrough rates with site-links, callouts, and snippets. Before this feature, users would see a callout and a structured snippet below an ad. Now the extensions will appear beneath the ad copy.
Internal data from Google suggests that users are twice as likely to interact with the new site links format, aided by clickthrough options that allow users to scroll side to side. Per the GIF in Google's blog post, it looks like users will be able to scroll through a movable carousel and view at least four structured snippets.
