With Google's mobile-first index on its way, SEO-minded webmasters are more focused on mobile load speed than ever before. Simply put, the AMP format allows content to load extremely fast on mobile. In turn, AMP content often sees a lower bounce rate, potentially better search rankings, and even improved engagement.
Now, Google has announced that AdWords search ads will fully support links to AMP landing pages. While it's not known if Google will show preferential treatment to ads that link to AMP pages, one thing is clear: users will be much more likely to engage with your landing page if it loads quickly.
