An online shop, a plumber and a dental clinic can all run Google Ads. They should not run the same campaigns. The right campaign type depends on what you sell and how your customer buys, and getting this one choice wrong is behind a lot of the wasted budget I find in audits.
Quick answer
- E-commerce store: Performance Max + Shopping, then brand and product Search. Track purchases with order value.
- Service business: keyword-focused Search, then Performance Max once lead data is solid. Track form submissions and qualified leads.
- Booking business: Search for top treatments, then Performance Max with your Business Profile linked. Track completed bookings.
Where the wrong campaign type wastes budget
The patterns repeat. A service business runs Performance Max with no lead tracking. A store runs only Search and never shows its products in Shopping. A clinic sends booking clicks to a homepage with no booking button. The ads run and the money goes, but the sales or leads don’t come.
Here is how I match campaign types to three common kinds of business.
E-commerce stores: Performance Max, Shopping and Search
An online shop sells products, so the ads should show the products. Most stores do best with three campaign types working together.
Performance Max uses your product feed and runs across Search, Shopping, YouTube, Display, Gmail and Discover from one campaign. It works well once Google has enough purchase data to learn from. Give it real purchase values, not just a count of sales, so it aims for revenue rather than cheap orders.
Standard Shopping gives you more control. You can split products by margin, best sellers or price range and bid differently on each. It is a good starting point for a new store, or a way to protect the products that make you the most money.
Search catches people who type exactly what they want: a brand name, a model number or “buy [product] online”. Keep a brand Search campaign too, so you can see what brand searches really cost instead of letting them hide inside Performance Max.
Before any of this, check three things:
- A clean Merchant Center feed with no disapproved products
- Purchase tracking that records the order value once
- Product pages that load fast on mobile

Service businesses: keyword-focused Search
Plumbers, lawyers, roofers, accountants and B2B services get their best leads from people who are already searching for help. That makes Search the core, built tightly around keywords.
- Group keywords by service, such as “emergency plumber” and “boiler repair”, and send each group to a page about that exact service.
- Use phrase and exact match for the main terms. Broad match can work later, once smart bidding has enough lead data.
- Check the search terms report every week and add negatives for jobs you don’t do, DIY searches and job seekers.
- Target only the areas you actually serve, and set the location option to people in or regularly in that area.
Track what matters: form submissions and real enquiries, not page views. If you can, import which leads became paying customers, so bidding learns which searches bring real work.
Why I don’t start a service business on Performance Max
In a Search campaign you choose the keywords, the match types and how much each one can spend. Performance Max takes most of that away. Google decides which searches to show up for, and it spreads the budget across Display, YouTube, Gmail and Maps too.
For a service business, that often means spend going to loosely related searches, people looking for a job or a DIY fix, or placements that bring cheap form fills and spam instead of real enquiries. You also can’t see clearly which search cost how much.
So keep the main budget in keyword-focused Search, where every dollar is tied to a search you picked. Test Performance Max later, with a small separate budget, only after lead tracking is solid and you can tell real leads from junk. See our local service Google Ads page for how we set this up.
Booking businesses: Search plus Performance Max
Dental clinics, med spas, salons, physios and other appointment-based businesses sit between the two. People search for the treatment, but many also browse, compare and book later.
Start with Search for the treatments that bring the most value, such as “dental implants near me” or “teeth whitening [city]”. Send each one to a treatment page with prices or a clear next step, and a booking button near the top.
Add Performance Max once bookings are tracked properly. It can reach people on Maps, YouTube and Display who are nearby but haven’t searched yet. Link your Google Business Profile so it can use your location.
The booking itself is where most accounts break. If people book through Calendly, a clinic system or a widget on another domain, make sure the completed booking is tracked, not just the click on “Book now”. Otherwise both campaigns optimise for clicks that never become appointments. Our conversion tracking setup and Google Ads for clinics pages cover this in more detail.
Fix the basics before you spend
Whatever campaign type you pick, it only works as well as what happens after the click. Before raising the budget, check that:
- The landing page matches the ad and works on mobile
- Tracking counts the real sale, lead or booking once
- The audience and locations are right
Get those right first, and every dollar has a job. You can see what this looks like in practice in our client results, and compare plans on our pricing page.
