Google Ads Campaign Types: Which Should You Use? (2026)

Picking the wrong campaign type is one of the fastest ways to burn a Google Ads budget. Each type does a genuinely different job — one captures people who are already searching for you, another shows banners to people who have never heard of you — and pointing the wrong one at your goal is like using a fishing net to dig a hole. It will move, but it will exhaust you and waste money. This guide explains the main Google Ads campaign types as they stand in 2026, what each is actually for, and how a Singapore SME should choose between them.

If you are completely new to the platform, read our complete Google Ads guide for Singapore SMEs first for the basics of the auction and how bidding works. This post assumes you know the fundamentals and want to choose the right campaign architecture.

The campaign types that exist in 2026

Google has quietly reshaped its line-up over the last two years. Smart Shopping and standard Discovery campaigns are gone, folded into newer AI-driven types. As of 2026, the campaign types you will actually choose between are:

Most Singapore SMEs will only ever need two or three of these. The art is in choosing them in the right order, not running all of them at once.

Search — capture existing demand

Search campaigns put text ads on Google’s results pages when someone searches for what you offer. Somebody types “aircon servicing Tampines” or “corporate lawyer Singapore”, and your ad appears above the organic results. This is the campaign type built around intent: the person is actively looking, right now, for a solution. That is why, for the majority of Singapore service businesses and lead-gen SMEs, Search is where you should start.

The economics are straightforward. You are meeting demand that already exists rather than trying to manufacture it, so the conversion rates are the highest of any campaign type and the path from click to enquiry is short. Search is also the type where the fundamentals you can control — keyword choice, ad relevance and landing-page quality — most directly decide your cost. A sharper, more relevant Search campaign earns a higher Quality Score and a lower cost-per-click, which is the cheapest lever you have.

In 2026, Google’s standard Search campaign has an AI-upgraded sibling — AI Max for Search, launched in 2025 — which loosens keyword matching and uses AI to find relevant queries and generate assets while keeping advertiser controls. It is essentially Search with the AI dialled up. For most SMEs, a well-built keyword Search campaign remains the dependable core; AI Max is worth testing once that core is performing.

Best for: lead generation, services, and any business whose customers actively search for what they sell. This is the default first campaign for most SMEs.

Shopping — sell catalogued products

Shopping campaigns show product listings — image, price, title and store name — directly in Google’s results and Shopping tab. They are driven not by keywords but by a product feed you maintain in Google Merchant Center. When the feed is accurate and well-optimised, Shopping is the most efficient way for a retailer to sell, because the shopper sees the product, the price and the photo before they even click.

For a Singapore e-commerce store, Shopping is often the foundation of the whole account. The work is in the feed: clean titles packed with the terms people search, correct pricing and stock status, strong primary images, and complete product attributes. A neglected feed produces weak Shopping performance no matter how much you bid.

Best for: e-commerce and any business with a catalogue of products that have clear prices and images.

Performance Max — automated and cross-channel

Performance Max is a single AI-run campaign that spans every Google channel at once — Search, Shopping, YouTube, Display, Discover, Gmail and Maps. You supply assets, an audience signal and a goal; Google’s AI assembles and places the ads. It is powerful and, since the 2026 transparency updates, far more controllable than it used to be — but it needs good conversion data and active oversight to avoid wasting spend. We cover it in depth in Performance Max explained for Singapore SMEs.

The short version for choosing: PMax shines for e-commerce with a healthy feed and solid conversion data, and for mature accounts wanting reach beyond Search. For a low-volume lead-gen business with thin data, it is usually not the right first move — start with Search and add PMax once the account is generating steady conversions for the AI to learn from.

Best for: e-commerce with good data, and accounts extending reach across channels.

Demand Gen — create demand on visual surfaces

Demand Gen is Google’s answer to social-style advertising. It runs across YouTube (including Shorts, in-stream and in-feed), Discover, Gmail and Maps, using image and video creative to reach people based on their interests and intent rather than a live search. It replaced Discovery campaigns — the migration completed by March 2024 — and in July 2025 it absorbed Video Action Campaigns, making it the single home for engagement-driven visual advertising on Google.

Think of Demand Gen as the upper-funnel partner to Search. Search captures people who already want you; Demand Gen introduces you to people who do not know you yet but match your audience. It is most useful once you have a working Search or Shopping engine and want to widen the top of the funnel with creative the way you might on Meta or TikTok.

Best for: building awareness and consideration with strong visual creative, especially for consumer brands.

Video — attention on YouTube

Video campaigns run ads before, during and around YouTube content. They are built for awareness, education and consideration rather than direct response — though with good targeting and a clear call to action they can drive conversions too. If you already have video assets (a brand film, product demos, testimonials), a Video campaign is a low-friction way to put them to work. If you do not, this is a campaign type to plan for rather than rush into, because weak video performs poorly.

Best for: awareness and consideration when you have, or can produce, decent video.

Display — reach and remarketing

Display campaigns place banner and image ads across the Google Display Network — millions of partner websites and apps. The defining feature is low intent: these people are reading an article or using an app, not searching for you. That makes Display a poor choice for cold lead generation, but an excellent and cheap one for remarketing — reminding people who already visited your site to come back. For most SMEs, Display earns its place as a remarketing layer, not a prospecting engine.

Best for: remarketing to warm audiences and topping up brand awareness cheaply.

App — installs and in-app actions

App campaigns are fully automated and exist for one purpose: driving installs and in-app actions for a mobile app. You provide assets and a goal, and Google promotes the app across Search, Play, YouTube and Display. If you do not have an app, you will never touch this type. If you do, it is the standard way to acquire users.

Best for: businesses promoting a mobile app.

How to choose — start from your goal

The mistake is choosing a campaign type because it sounds advanced. Choose from your goal instead:

• Leads now, from people already searching → Search. The default for nearly every Singapore service SME.
• Selling catalogued products → Shopping, then Performance Max. Get the feed right first.
• Cross-channel conversion with good data → Performance Max. Best once conversions are flowing.
• Awareness and consideration → Demand Gen and Video. Upper-funnel, after your capture engine works.
• Remarketing warm visitors → Display. A cheap layer, not a standalone strategy.
• App installs → App campaigns. Only if you have an app.

A realistic rollout for a Singapore SME looks like this. Month one: a tight Search campaign on your highest-intent keywords, with conversion tracking nailed down. Once that is profitable and generating steady conversions, add Performance Max (retailers) or Demand Gen and Video (services and consumer brands) to widen reach, plus a small Display remarketing campaign to recover visitors who did not convert. That sequence — capture demand first, then create it — keeps you from spraying budget across channels before you have proof that the offer and tracking work.

Matching campaign types to the funnel

It helps to stop thinking of campaign types as a menu and start thinking of them as stages in how a customer comes to you. Every buyer moves through a rough journey — from not knowing you exist, to becoming aware, to actively looking, to choosing. Different campaign types are built for different points on that journey, and pointing a top-of-funnel type at a bottom-of-funnel goal (or the reverse) is the root of most wasted spend.

• Bottom of the funnel — active demand. People searching “emergency plumber Bukit Timah” want a plumber now. Search (and Shopping for products) captures them. This is where conversions are cheapest per outcome and where almost every SME should put its first dollar.
• Middle of the funnel — consideration. People comparing options, watching reviews, reading guides. Demand Gen and Video reach them with creative that builds preference before they search.
• Top of the funnel — awareness. People who do not know they have a problem you solve. Demand Gen, Video and Display introduce you. Judge these on assisted conversions and brand-search lift over time, not last-click leads.
• Re-engagement — warm but undecided. People who visited and left. Display remarketing and remarketing lists in Search and PMax bring them back cheaply.

The reason Search comes first for nearly every Singapore SME is simple: it is the only stage where the customer has already raised their hand. Creating demand is more expensive and slower to prove than capturing it, so you capture first, then — once the offer and tracking are validated — invest upstream to fill the funnel. A retailer with a strong feed is the main exception, because Shopping and Performance Max can profitably lead from day one.

How budget changes the right mix

The right campaign mix is not fixed; it scales with what you can spend. On a tight monthly budget — say a few thousand dollars — concentration beats coverage. Put everything into one or two Search campaigns on your highest-intent keywords so they gather enough data to optimise, rather than sprinkling small sums across five campaign types that each starve. As budget grows and the Search engine proves profitable, you add Performance Max or Demand Gen and a small remarketing layer, giving each enough spend to actually learn. The discipline is the same at every level: never add a campaign type you cannot fund well enough to generate the conversions it needs to improve.

Budget and GST realities for Singapore

Whichever types you run, two local facts apply. First, GST of 9% has been charged on Google Ads spend since 1 January 2024, on both media and any agency management fee, so budget the gross amount. Second, click costs vary widely by sector — roughly S$1.50 to S$6 per click for most industries, rising to S$8–S$11 for competitive legal and B2B terms, and often under S$3 for retail and wellness. The campaign type you choose interacts with those costs: Search puts you in the most competitive, highest-intent auctions, while Display and Demand Gen impressions are far cheaper but convert at lower rates. For the full picture, see how much Google Ads cost in Singapore.

One grant clarification, since it is a common question: ad spend and ongoing management are generally not claimable under PSG or similar grants, which fund pre-approved software, not media budgets. SDM is a pre-approved PSG vendor for eligible solutions, but the client applies for and manages any grant directly.

Common campaign-type mistakes

• Running Display for cold lead generation and wondering why nothing converts.
• Jumping straight to Performance Max before the account has any conversion data.
• Launching Shopping with a thin, error-filled product feed.
• Running every campaign type at once on a small budget, so none gets enough data to learn.
• Treating Demand Gen and Video as direct-response and judging them on last-click leads alone.

If your clicks are healthy but enquiries are not, the campaign type may not even be the issue — work through why Google Ads stop converting before adding more campaigns. And if you are still deciding whether Google Ads or organic search is the better first investment, our comparison of SEO versus Google Ads in Singapore lays out the trade-offs.

The bottom line

There is no single best campaign type — only the right type for a specific goal and stage. Most Singapore SMEs should start with Search to capture demand that already exists, get conversion tracking and Quality Score right, and only then layer on Performance Max, Demand Gen, Video or Display to extend reach. Build in the right order, and each campaign type does the job it is actually good at. The results other businesses have seen are worth more than any sales pitch — our case studies show what the right structure delivers.

FAQ

What are the main Google Ads campaign types in 2026?

Search, Performance Max, Shopping, Demand Gen, Video, Display and App. Each suits a different goal — Search for high-intent demand, Shopping and Performance Max for e-commerce, Demand Gen and Video for awareness, Display for remarketing, and App for installs.

Which campaign type should a small business start with?

Usually Search. It puts your ad in front of people who are actively searching for what you offer, which gives the highest conversion rates and the shortest path from click to enquiry — ideal for proving the offer before you scale.

What is best for e-commerce?

Shopping and Performance Max, both driven by your Merchant Center product feed. Get a clean, well-optimised feed in place first; the feed quality decides how well both perform.

What happened to Discovery campaigns?

They were replaced by Demand Gen, with the migration completing by March 2024. Demand Gen also absorbed Video Action Campaigns in July 2025, so it is now Google’s single home for visual, engagement-driven advertising across YouTube, Discover and Gmail.

Is Display good for lead generation?

Not for cold prospecting — intent on Display is low because people are browsing, not searching. Display works best as a cheap remarketing layer that brings back visitors who already came to your site.

How many campaign types should an SME run at once?

As few as do the job. On a small budget, spreading spend across many types starves each of the data it needs to optimise. Start with one or two, prove they work, then add more deliberately.
