Google has joined Twitter in revising its political ad rules ahead of what promises to be a brutal election season. But while the latter chose to ban political advertising altogether, Google is mainly limiting the ability to target political demographics, and promises to take action against “demonstrably false claims.”

In a blog post Wednesday afternoon, the search giant explained the new rules in a way that is clearly intended to be understood by a broad audience, not the ad-buying elite.
