What Are Google Ad Extensions And How To Use Them Effectively

Look at a typical Google search results page in Singapore for something like “aircon servicing” or “accounting firm”. The top ads rarely stop at a headline and two lines of text. Many also show links to specific service pages, short selling points, a phone number, an address or a list of services. Those extra pieces are what most people still call Google ad extensions.

Google now calls them assets. The name changed, the idea did not: they give searchers more reasons and more ways to contact you, and they can make your ad larger and more useful without adding to your cost per click on their own. Used carelessly, though, they add clutter, outdated offers or claims you cannot back up.

This guide explains what Google ad extensions are, why Google renamed them, which asset types matter for Singapore SMEs, how to set them up properly, how to measure them and the mistakes worth avoiding.

What are Google ad extensions?

Ad extensions are extra pieces of information attached to a Google Ads text ad, such as sitelinks, callouts, a phone number or a location. Google’s About assets help page describes assets as content that adds useful business information to your ad.

Three points about how they work are worth understanding early:

• They do not always show. Google decides on each search whether to show assets, and which ones, based on factors such as predicted performance, the space available and your ad’s position. Google recommends adding every relevant asset because they only appear when predicted to help.
• They can affect your Ad Rank. Google’s Ad Rank factors include the expected impact of assets and other ad formats. Good assets can therefore help your ads compete, not only look bigger.
• Clicks are charged normally. Adding assets has no separate fee. In general, a click on an asset such as a sitelink is charged like a click on the headline.

Why Google renamed extensions to assets

In 2022 Google began renaming ad extensions as “assets” in Google Ads. Sitelink extensions became sitelink assets, callout extensions became callout assets, and so on. Existing extensions were moved over automatically, so most advertisers did not need to rebuild anything.

The new name reflects how Google now builds ads. Responsive search ads, Performance Max and other formats assemble ads from components (headlines, descriptions, images, logos, sitelinks) and choose the best combination for each search. Calling everything an “asset” puts those parts under one system and one set of reports.

For you, the practical consequences are simple:

• Look for Assets, not Extensions, in the Google Ads interface.
• Older guides that mention extensions still describe the same features, though menu locations and some limits may have changed.
• Google can also create some assets automatically, such as dynamic sitelinks or callouts drawn from your website. Review the account-level automated assets settings so you know what can appear in your name.

The main asset types and when to use them

Not every asset suits every business. This table summarises the types most Singapore SMEs use on Search campaigns.

Sitelinks

Sitelinks are usually the most valuable asset. Add at least four, each pointing to a page that matches a different need: a service page, pricing, reviews or case examples you can genuinely show, and a contact or booking page. Keep link text short and specific, such as “Office Cleaning” rather than “Click Here”.

Callouts and structured snippets

Callouts are short phrases that support your headline. Good examples are factual and checkable: “Same-day quotes”, “Open Saturdays”, “English and Mandarin service”. Structured snippets use a header chosen from Google’s list, such as Services, Courses, Brands or Neighbourhoods, followed by values. A tuition centre might use Courses: PSLE Maths, O-Level Chemistry, A-Level Physics, as an illustrative example.

Call and location assets

In Singapore many customers still prefer to call or message before booking. If phones matter, add a call asset and schedule it to show only when someone is available. For location assets, link your Google Business Profile and keep its address, hours and phone number up to date, because that is where the details come from.

Price, promotion and lead form assets

Price assets work only when prices are stable and accurate. Promotion assets suit dated offers during busy periods such as Chinese New Year, the Great Singapore Sale or year-end; our festive marketing calendar helps with timing. Lead form assets collect personal data inside Google, so make sure your consent wording and follow-up process meet your obligations under the PDPA; see our PDPA guide for marketers.

How to use Google ad extensions effectively

Google’s own advice in Use as many asset types as possible is to add every asset type that is relevant to your business. That is a sensible starting point, but relevance and accuracy matter more than quantity.

• Match assets to the ad group. Assets can be set at account, campaign or ad group level, and the more specific level takes priority. A plumbing ad group should show plumbing sitelinks, not your aircon page.
• Write for the searcher’s next question. If people want to know price, location or timing, use assets that answer it.
• Avoid repeating the headline. Assets should add new information. Repetition wastes space.
• Keep every claim true. Only state awards, accreditations, warranties or ratings you can prove. Misleading claims can breach advertising policies and damage trust.
• Send sitelinks to strong pages. Each linked page needs a clear call to action, works well on mobile and loads quickly. See our guide to landing page design.
• Coordinate with your ad copy. Headlines, descriptions and assets work as one message. Our article on writing ad copy covers the core ad text.

Google’s Add assets help page walks through creating each type.

How to measure whether assets are working

Asset reporting in Google Ads shows impressions, clicks and other metrics for each asset, and you can compare performance across asset types. Use it to answer practical questions rather than chase small differences:

• Which sitelinks get clicks, and do those visits lead to enquiries?
• Do calls from the call asset turn into bookings? Set up call conversion tracking so you can tell.
• Are any assets disapproved, limited or never shown?
• Did adding assets change click-through rate or Quality Score components over several weeks?

Remember that asset metrics show performance when the asset appeared, often alongside other assets. Treat them as directional rather than precise proof of cause. Better click-through rate and Ad Rank can also help you improve impression share on the searches that matter.

A 30-day plan to set up and improve your assets

1. Days 1–3 (campaign owner): audit current assets at account, campaign and ad group levels. List what exists, what is disapproved and what is outdated.
2. Days 4–7 (marketing lead): agree a short list of true selling points, current prices and promotions, and the pages each sitelink should use.
3. Week 2 (campaign owner): add at least four sitelinks, several callouts and one or two structured snippet headers to each main campaign, plus call and location assets where relevant.
4. Week 2 (business owner): confirm Google Business Profile details, phone coverage hours and any lead form follow-up process.
5. Week 3 (campaign owner): review automated asset settings and remove anything you would not want shown.
6. Week 4 (campaign owner and marketing lead): check asset reports, replace weak sitelinks and callouts, and set calendar reminders to update promotions and prices.

How AI can help with ad assets

AI tools are useful for the drafting and checking side of asset work. They can:

• Draft callout and sitelink variations within character limits for a person to edit.
• Suggest structured snippet values based on your service pages.
• Flag assets that point to broken pages or mention expired dates.
• Summarise asset performance across many campaigns.

The limits are important. AI can invent selling points, round up claims or suggest promotions you do not offer. A person who knows the business must check every claim before it goes live, especially in regulated industries.

Marketing2u’s AI Ads Agent reads Google Ads data on a read-only basis and recommends improvements, including creative suggestions, without changing your account. If your sitelinks point to pages that need work, the AI Content Agent can draft landing page and FAQ content for you to review and approve.

Common mistakes with Google ad extensions

• Setting them up once and forgetting them. Old promotions, changed phone numbers and closed outlets keep showing.
• Using the same assets for every campaign. Generic assets dilute relevance.
• Making claims you cannot prove. “Best in Singapore” or unverified ratings invite complaints and policy problems.
• Showing call assets after hours. Unanswered calls waste money and frustrate customers.
• Ignoring automated assets. Know what Google may create on your behalf and switch off anything unsuitable.
• Judging by clicks alone. A sitelink with many clicks but no enquiries needs a better page, not praise.

Next steps

Google ad extensions, now called assets, are one of the simplest ways to make a Search ad more useful and more competitive. Start with sitelinks, callouts and structured snippets, add call and location assets where they suit how your customers contact you, and keep every detail accurate. Review asset reports monthly and update prices and promotions on a schedule, and your ads will keep giving searchers good reasons to choose you.

Frequently asked questions

Are Google ad extensions and assets the same thing?

Yes. Google renamed ad extensions to assets in Google Ads in 2022, so sitelink extensions became sitelink assets and so on. The features work in much the same way; the interface and reports now use the word assets.

Do ad extensions cost extra?

There is no separate charge for adding assets. You pay for clicks as usual, and in general a click on an asset such as a sitelink is charged like a click on the main ad. Assets can still affect cost indirectly by changing click-through rate and Ad Rank.

Why are my sitelinks or callouts not showing?

Google decides on each search whether to show assets, depending on predicted performance, available space and your ad’s position. Assets may also be disapproved or set at a level that a more specific ad group setting overrides. Check the asset status in your account and make sure each asset is relevant to the ad group.

How many sitelinks should I add?

Google recommends at least four sitelinks per campaign. Each should link to a distinct, useful page, such as a specific service, pricing or contact page, rather than repeating the main landing page.
