How to Use Ad Extensions to Dominate the Search Results

Learning how to use ad extensions to dominate the search results is one of the cheapest wins in paid search, because extensions (officially called assets in Google Ads since 2022) cost nothing extra to add and can push your listing from three lines of text to twelve. The advertiser who fills the most vertical space on a phone screen usually wins the click, even when a competitor bids higher. This guide covers the asset types worth using, where to add them, how many actually show, and how to read the performance data afterwards.

What Ad Extensions Actually Do to the Search Results

An extension is any extra piece of information attached to a text ad: sitelinks, callouts, phone numbers, prices, images, locations. Google pulls in whichever combination it predicts will perform best for that specific auction, device and query. You supply the raw material, the auction decides what to display.

Two things happen when your assets are strong. First, your ad occupies more pixels, which shrinks the space left for the organic listings and the competitor sitting below you. Second, expected click-through rate improves, and because expected CTR feeds Ad Rank, better assets can lower what you pay for the same position.

Google’s own Ads Help Center is blunt about the trade-off: assets are factored into Ad Rank, so ads with useful, relevant assets tend to earn better placement at equal or lower bids. Microsoft Advertising works the same way, with its own ad extension documentation covering near-identical formats.

The Asset Types Worth Building First

There are roughly a dozen manual asset types in Google Ads, but they are not equally valuable. If you are starting from an account with none, build them in this order:

• Sitelinks (minimum four, ideally six to eight): deep links to specific pages such as pricing, reviews, a category page or a booking form. Each gets two description lines, so a full sitelink set can add four extra lines of copy.
• Callouts (minimum six, 12 to 25 characters each): non-clickable proof points like “Free On-Site Quotes”, “Family Owned Since 1998”, “Same-Day Dispatch”.
• Structured snippets: a header such as Services, Brands or Types followed by three to ten values. Useful for showing range without writing sentences.
• Call assets: a phone number with scheduling so it only shows when someone can actually answer.
• Image assets: 1200×1200 square and 1200×628 landscape versions, which frequently lift CTR on mobile by a noticeable margin.
• Location and affiliate location assets: pulled from your Business Profile, essential for anything with a physical catchment area.
• Lead form, price, promotion and app assets: situational, but price assets are quietly excellent for ecommerce and service menus.

Business logo and business name assets round out the set for search campaigns. They are quick to add and they make the listing look like a brand rather than an anonymous URL.

How Many Extensions Appear Under an Ad?

In practice Google shows up to four assets per impression on the search results page, and often fewer. That is not a reason to add four. The system chooses from everything eligible, so a bigger pool means a better chance of a strong combination for each individual query.

A reasonable target for most accounts: eight sitelinks, ten callouts, two structured snippet headers, four to six images, plus call and location assets where relevant. Think of it as auditioning candidates rather than filling slots.

Add Assets at the Right Level of Your Account

From top to bottom, a healthy search account hierarchy runs account, campaign, ad group, then keywords and ads. Assets can be attached at the first three levels, and the most specific one wins.

1. Account level: generic trust builders that apply everywhere, such as your logo, main phone number and callouts about guarantees or delivery.
2. Campaign level: assets that match the theme, so a “commercial roofing” campaign gets different sitelinks from a “gutter repair” campaign.
3. Ad group level: your sharpest work. If an ad group targets a single product, the sitelinks and price assets should reference that product by name.

Brand campaigns deserve their own treatment. A brand keyword search already signals intent, so use sitelinks that route people to account login, store locator or support, while non-brand campaigns should push comparison and proof pages. That distinction matters enough that it should shape your keyword research for Google Ads from the start.

The Pixel-Dominance Play Competitors Miss

Most articles stop at “add all the extensions”. The strategic layer is deciding what a searcher sees in the top four inches of a phone screen, because on mobile that is the entire visible result set. Your goal is to occupy it with your own assets rather than share it.

Three moves do most of the work here. Write sitelink descriptions for every sitelink, since sitelinks without descriptions collapse into a single compact row on desktop. Add images so the listing carries a visual anchor. Then keep your primary text ad strong, because assets amplify a good ad and cannot rescue a weak one, which is why the structure of a high-converting search ad still comes first.

Pin sparingly in responsive search ads. Over-pinning restricts the combinations Google can test and often suppresses asset display, which defeats the purpose of the whole exercise.

Automated Assets: Keep, Watch or Turn Off

Google generates dynamic sitelinks, dynamic structured snippets, automatically created assets and seller ratings without you lifting a finger. Some are helpful. Some pull awkward sentences from your landing pages and attach them to your brand.

Review them monthly under Assets, then Automated assets, then More, then Account level automated assets. You can disable individual types with a written reason. A sensible default is to keep seller ratings and dynamic sitelinks while switching off automatically created assets once your manual set is genuinely complete.

Measuring Extension Performance

Asset reporting sits in the Assets tab, where each item carries its own impressions, clicks and conversion data, plus a performance label of Low, Good, Best or Learning. Read these labels as directional rather than absolute, since low-volume assets often sit in Learning for weeks.

• Replace any asset marked Low after it has accumulated at least 1,000 impressions.
• Compare CTR before and after a rollout across a 30-day window, and expect a lift somewhere in the 5 to 15 percent range for accounts that previously ran bare ads.
• Segment by device, because image and call assets behave very differently on mobile than desktop.
• Watch Quality Score alongside it, since expected CTR is one of its three components and often moves first. Our breakdown of how Quality Score works and how to improve it explains the mechanics.

Pair asset changes with your bidding approach rather than testing both at once. If you are mid-experiment on manual versus automated bidding, wait for that to settle before you rewrite every sitelink.

Housekeeping That Protects Your Work

Assets break quietly. A sitelink pointing at a discontinued product page or a promotion asset with a lapsed end date will get disapproved without anyone noticing until performance dips.

Build a quarterly check: verify every sitelink URL resolves, confirm promotion dates, refresh seasonal callouts, and add negative keywords (prefixed with a minus symbol in the editor) so your polished assets are not showing against irrelevant broad match traffic. If several people touch the account, control who can edit what, in the same spirit as managing user roles and permissions on your website. Store owners should also make sure the destination pages are ready, which is where the right WooCommerce extensions to boost sales earn their keep.

Frequently Asked Questions

How to maximize Google search results?

Add every relevant asset type, then keep at least eight sitelinks and ten callouts active per campaign so Google has enough material to build a tall listing. Combine that with strong ad copy and a high Quality Score, since Ad Rank determines whether your expanded format gets the top position at all.

How many extensions should you include in your search ads?

Google displays a maximum of four assets per impression, but you should supply far more than four: eight sitelinks, ten or more callouts, two structured snippet headers and at least four images is a solid baseline. A deeper pool lets the auction pick the best combination for each query and device.

How to make responsive search ads?

Provide up to 15 headlines (30 characters each) and 4 descriptions (90 characters each), aim for at least 10 headlines, and pin only when legally or structurally necessary. Google then assembles combinations and reports an Ad Strength rating, and our guide to writing ad copy that drives clicks covers what to put in those fields.

How to get the best results from Google Ads?

Tight account structure, negative keyword discipline and a full asset set typically deliver more improvement than bid tinkering, often within the first 60 days. Track conversions properly, review search terms weekly, and separate brand from non-brand campaigns so the reporting tells you something useful.

Want a Second Pair of Eyes on Your Account?

If your ads are running bare or your assets have not been touched in a year, an audit usually surfaces several hours of quick fixes with measurable upside. There are also real advantages to working with a local agency that knows your market, and you can get in touch with SEO Quirk to talk through what your account needs next.
