A local service business looking for quote requests needs a different advertising plan from an online shop selling hundreds of products. Choosing a campaign because it is new, heavily promoted or easy to switch on is a poor substitute for deciding what a worthwhile result looks like.
Start with the customer action you want, the information you can measure and the material you have available. Then choose the campaign type that fits. You do not need to run every type at once.
Campaign types and ad formats are different
A campaign type determines the broad delivery system, settings and available advertising opportunities. An ad format is how a particular ad appears, such as a responsive search ad, product ad or video ad. More than one campaign type can use video or show on the same Google property.
Google’s campaign-type overview is a useful reference. The comparison below adds practical selection questions for a small business; it is not a ranking of campaigns from best to worst.
Compare the main campaign types
| Campaign | Suitable objective | Data and assets | Useful advantage | Main limitation or question |
|---|---|---|---|---|
| Search | Enquiries or sales from people actively searching. | Relevant keywords, ad copy, useful landing pages and conversion measurement. | Connects an offer with an expressed search need. | Search demand, competition and query relevance constrain the opportunity. |
| Standard Shopping | Online product sales. | Merchant Center product data, eligible products, a working store and purchase measurement. | Product-led advertising with campaign and product-group management. | Feed quality and product economics matter; it is not a keyword-led Search campaign. |
| Performance Max | Measured sales or leads across Google’s advertising inventory. | Reliable goals and values, suitable creative assets, landing pages and a product feed for retail use. | Coordinates automated delivery across channels. | Requires oversight of goals, lead quality, assets and where traffic lands. |
| Demand Gen | Build interest and encourage action through visual advertising. | Strong images or video, audience planning, relevant pages and suitable measurement. | Can demonstrate an offer before someone searches for it. | Creative quality and the customer’s longer decision journey affect evaluation. |
| Display | Reach, consideration or re-engagement. | Images, copy, audience or contextual planning and placement review. | Visual reach beyond search results. | An impression or cheap click does not establish purchase intent. |
| Video | Awareness, reach or views, according to the selected subtype. | Purpose-made video, an appropriate audience and objective-specific measurement. | Shows a product, process or story in motion. | Views need a business purpose; a video is not automatically an enquiry source. |
| App | App installs, engagement or eligible pre-registration activity. | An app, relevant app/store assets and app-event measurement. | Delivery built around app outcomes. | Not relevant to a business that only needs website enquiries. |
Search: reach people looking for what you offer
Search is often a sensible starting point for a service with recognisable demand. A person searching for a local installer or a specific repair may be close to contacting a provider. The campaign still needs careful query matching, locations, negative keywords, relevant ad assets and a page that answers the search. Google’s Search campaign setup guidance explains the core settings.
For an illustrative plumber, “hot water cylinder replacement” and “plumbing apprenticeship” describe very different needs. Buying traffic without checking those differences can use up the budget on visitors the business cannot help.
Group related services sensibly and send people to the relevant service page. Review actual search terms and lead quality rather than assuming that every click on a chosen keyword is valuable.
Standard Shopping: advertise the products in your store
Shopping ads can show product information such as an image, title and price before the visitor reaches the store. Google uses product data rather than a positive keyword list to match Shopping ads. Google’s Shopping campaign guidance explains this distinction.
Standard Shopping is worth considering when product-focused campaign management suits the retailer’s needs. A clean feed is only the starting point: pricing, delivery, stock, the product page and checkout all influence whether a click can become a profitable order. Our Google Shopping guide covers that preparation in more detail.
Performance Max: give automation a sound goal
Performance Max is a goal-based campaign type that can access inventory across Google’s channels. It uses automated bidding and delivery, informed by your goals, assets and other inputs. Retail campaigns can use a Merchant Center feed.
Automation makes the quality of the goal especially important. If an account treats any form attempt or low-value action as a valuable lead, the campaign can optimise towards an outcome the business does not actually want.
For lead generation, review whether enquiries are genuine, relevant and commercially useful. Where appropriate, connect later qualified-lead or sales outcomes back to measurement. For retail, check purchase values and product margins. Do not describe Performance Max as “set and forget”, or assume that broader channel access guarantees better results than a more focused campaign.
Demand Gen: use visual material to create interest
Demand Gen suits offers that benefit from being seen or demonstrated. A homewares store might show a room setting; a service business might explain a visible before-and-after process, using genuine work and appropriate permissions.
Its eligible channels include visual environments such as YouTube, Discover and Gmail, with additional channel options depending on settings and eligibility. Google’s Demand Gen channel controls document the current options. It should not be described simply as the old Discovery campaign under a new label.
Allow for creative production and refreshes. If there is no convincing image, video or offer, choosing a visually led campaign does not solve that weakness.
Display and Video: decide what attention is worth
Display campaigns place visual ads across the Google Display Network. They can support awareness or re-engagement, but audiences, placements, exclusions and frequency deserve attention. Large impression totals are not a substitute for useful customer activity.
Video campaigns offer ways to reach viewers on YouTube and eligible video partner inventory. Select the subtype and formats around the objective, and check the currently available options. For a performance-focused visual campaign, Demand Gen may also be relevant.
A short demonstration with a clear opening and readable captions may be more useful than repurposing a long corporate presentation. Decide in advance whether success means relevant reach, engaged viewing, enquiries or sales, and assess the campaign accordingly.
App campaigns: only when the app is the product journey
App campaigns promote app-related outcomes, including installs and in-app engagement. They draw on app information and supplied assets across eligible Google properties.
A business with a normal website and enquiry form does not need an App campaign. For a business with an app, define the valuable action beyond installation: a booking or purchase may matter more than a large number of installs that are never used.
Lead generation and ecommerce need different checks
For a service business, start with the offer, service area and capacity to respond. A confirmed enquiry is more meaningful than a button click. Track the route from enquiry to qualified opportunity where possible, and watch for spam, unsuitable requests and calls outside the service area.
For an online shop, check the feed, stock, delivery and purchase journey before scaling spend. Record accurate transaction values and avoid counting a purchase twice. A1’s ecommerce website design service can help address the store experience that advertising depends on.
These checks apply whichever campaign type you choose. Google’s conversion measurement guidance explains the available measurement approaches; the business still needs to decide which actions represent real value.
Set a budget and a review plan together
A realistic budget covers the media spend and the work needed for creative, landing pages, measurement and management. There is no universal daily amount that makes a campaign viable. Local demand, competition, margins, sales cycles and the cost of winning a customer all affect the decision.
Start with a manageable scope instead of dividing a small budget among every campaign type. Agree what evidence will justify continuing, changing or stopping. Allow for conversion delays and avoid changing settings so often that comparisons become meaningless.
If you need help choosing the first campaign or assessing an existing mix, A1’s Google Ads management service can review the offer, measurement and landing pages alongside the campaign settings.
