Ad Assets: The Free Space Most Google Ads Never Claim

Search for any competitive service and compare the ads. One is three lines of text. Another fills half the screen: extra links underneath, a phone button, small print about same-day service, prices listed. Both advertisers pay per click, but one of them occupies triple the space and gives a searcher four different reasons to choose them. The difference is not budget. It is assets, and they are free.

Assets (Google renamed extensions a while back) are the attachments on a search ad: sitelinks, call buttons, callouts, structured lists, prices, images. Most small accounts run none, or two stale ones created at setup. Filling them in properly is an hour of typing, and it is one of the few things in Google Ads that improves results without increasing spend.

Why free space changes the economics

Three effects stack. A bigger ad simply gets seen and clicked more, and click-through rate feeds the quality scoring that decides what you pay per click. The extra links let different searchers pick their own door: one person wants prices, another wants to call now, another wants to read about the specific service. And every line of assets pushes the next advertiser further down the screen.

Google only shows assets when your ad ranks well enough, so a weak account will not display all of them all the time. That is fine. You provide the inventory; the auction decides the layout per search.

The four that matter for a service business

Call assets, first and most important. If your business runs on phone calls, the call button on a mobile ad is the shortest path from search to conversation that exists in advertising. Pair it with call reporting so those calls count as conversions, and schedule it to your answering hours: a call button at 2 AM that rings nobody is worse than no button.

Sitelinks, four minimum. Each one is a mini-ad to a specific page: Name Corrections, Date Changes, Senior Fares, Contact Us. Write real descriptions under each, because described sitelinks earn the large ad format. Point each at its matching page, never all four at the homepage.

Callouts, the small print that answers objections. Short phrases, no links: "Same-day handling", "No hold time", "Serving customers 12 years", "WhatsApp support". Write them from the questions people actually ask before they buy.

Structured snippets or prices, if they fit. A Services list ("Flight changes, Cancellations, Group bookings") tells the searcher the menu before they click. Price assets suit businesses comfortable naming numbers; they filter out bargain-hunters before you pay for the click, which is a saving disguised as transparency.

An hour of setup, done properly

• Write 6-8 sitelinks with descriptions, then let campaigns share the best 4-6
• Write 8-10 callouts and rotate the strongest
• Add the call asset with your answering-hours schedule
• Add one Services structured snippet
• Check the combinations report a fortnight later to see what Google actually shows

Then leave them alone, with one exception: anything seasonal. A "Holiday booking help" sitelink in March tells every searcher the account is unattended, and searchers read staleness as closed-for-business.

The mistakes that waste the free space

Repeating the headline in every asset, so the bigger ad says nothing extra. Pointing sitelinks at the homepage, which turns four doors into one door with four signs. Writing callouts nobody would question ("Quality service", "Trusted company") instead of specifics a competitor could not honestly copy. And the quiet one: never opening the combinations report, so a broken or embarrassing pairing runs for months unseen.

FAQ

Do assets cost extra when someone clicks them?

A click on a sitelink or call button is billed like any ad click, once per ad impression regardless of what was clicked. The assets themselves cost nothing to add or display, which is exactly why an empty asset section is money left on the table.

Why does Google show my assets only sometimes?

Display depends on rank and predicted usefulness per search. Higher positions earn more attachments. If assets rarely show, the fix is usually the underlying ad relevance and landing page, the same levers as Quality Score, rather than the assets themselves.

Should assets differ per campaign?

Sitelinks yes, tailored to each campaign's service. Callouts and the call asset can be shared account-wide, since they describe the business rather than the offer. The rule of thumb: the closer an asset sits to a specific search intent, the more specific it should be.
