Ad Assets — The Free Clicks Most Advertisers Leave on the Table

What Assets Do

Assets (formerly extensions) are additional content—sitelinks, callouts, images, calls, locations, structured snippets—that make your ad bigger, more informative, and more clickable. Google selects which assets to show based on each auction, and the incremental cost of adding assets is typically lower than the cost of moving up a position. In other words: assets are often the cheapest way to get more clicks.

The Numbers That Should Convince You

Image assets alone deliver a 6% average CTR increase in Search campaigns. Sitelinks can increase clickthrough by 10-15%. And here is the detail most people miss: Google charges no more than two clicks per impression for an ad and its assets. So even if someone clicks a sitelink and then your headline, you pay for at most two clicks—often less.

The Asset Checklist Every Account Needs

At minimum, every Search campaign should have: 4+ sitelinks with descriptions, 4+ callout extensions, structured snippets for your most relevant categories, image assets (at least 4 unique, both square 1:1 and landscape 1.91:1), and a business name plus logo. For PMax, the asset requirements are more extensive: minimum 3 headlines (30 char), 1 long headline (90 char), 2 descriptions (90 char), plus landscape, square, and portrait images, and ideally a video.

The biggest mistake I see: advertisers set up assets once and never update them. Stale callouts referencing last year’s promotion, sitelinks pointing to discontinued products, images that no longer match the landing page. Assets need the same refresh cadence as your ad copy.
