Choosing the right platform puts your ad in front of the right people. Where the money goes after that is a separate question. Budget can slip away inside the account, through settings that decide which searches trigger your ad and where an automated campaign chooses to spend.
Part 1 of this series matched each platform to what your customer is doing: Google for people searching right now, Meta for people who haven’t started looking, and Pinterest for people planning. It also covered what to set up first: a clear definition of a result, tracking tags, and a landing page built for the ad.
This part looks at two of those places on Google: Performance Max, an automated campaign type that can suit some businesses and mislead others, and the match types and negative keywords that control which searches you pay for.
Check Whether Performance Max Fits Your Business
Performance Max, often shortened to PMax, is a Google campaign type that runs ads across Search, Shopping, Display, YouTube, Gmail, and Discover from a single campaign. You supply headlines, descriptions, images, and videos, plus hints about your audience, and Google’s automation decides where each ad appears and how much to bid.
The trade is visibility. You can see the results, but not much of how Google reached them, which marketers often call a black box. It also takes time to learn, and Google recommends allowing several weeks before you judge the results. It works best for businesses with a large catalog and plenty of data, and it’s a weaker bet for most service businesses.
Whether it fits depends on what you sell.
- Online stores with a product feed fit best. A product feed is a continuously updated list of your products (names, prices, availability, and images) that you connect through Google Merchant Center. That detail gives the automation plenty to work with, and it can put products in front of shoppers who are ready to buy.
- Accounts with steady conversions fit too. The automation learns from results, so it needs a regular supply of them. A commonly recommended minimum is 30 to 50 conversions a month per campaign, and more is better.
- Lead generation is where it often disappoints. PMax is very good at producing the action you define, such as a form submission or a phone call, but it has no way to know what happens next. It counts a form filled out by someone who was never going to hire you the same as one from a ready buyer. Marketers who run these campaigns report strong conversion numbers and attractive costs per lead that turn out to be poor prospects once someone follows up.
- Smaller budgets and newer accounts struggle to feed it. With little conversion history, the learning period stretches out and early results are unreliable. You pay for that learning with no guarantee of a return.
A strong conversion report can still hide a weak result. What counts is what happens after the lead arrives, whether it becomes a booked job or a sale. For a service business, standard Search is the lower-risk place to begin, because you can see which searches trigger your ads and adjust them directly.
Set Guardrails Before Performance Max Spends a Dollar
Performance Max follows the limits you set, so set them before the first day. Google’s automation fills whatever room you leave open, and a few of its defaults can send paid clicks somewhere you never intended.
If you decide to try it, start with this:
- Restrict URL expansion. By default, Google can send visitors to any page on your site instead of the one you chose, including blog posts and other pages unlikely to turn a visit into a customer. You pay for the click either way. You can limit this in the campaign settings, and doing so is recommended as standard practice.
- Add exclusions before launch. Negative keywords, which are search phrases you tell Google never to show your ads for, work in Performance Max much as they do in standard Search campaigns. You can also exclude specific pages and audience segments. Setting these up front costs less than reacting after the budget has already gone to the wrong searches.
- Switch off auto-apply and review automated assets. Auto-apply recommendations let Google make its own suggested changes to your account without asking, and automated assets can send visitors to pages you didn’t pick. Check both, and turn off anything that points somewhere unintended.
- Define a conversion that means a customer. A page visit or another small click teaches the automation to find the wrong people, so count a phone call, a booking, or a completed form. If you can, connect your customer relationship management (CRM) tool, the software where you track leads, so you can see which ones become customers.
- Feed it good inputs. Provide a varied set of headlines, descriptions, images, and videos instead of the minimum, so there are more combinations to test. Audience signals, the hints you give about who to reach, are starting points and not boundaries, and a list of past customers or website visitors is the most valuable hint you can offer.
- Run Search alongside it, and give it time. A standard Search campaign gives you a benchmark, so compare lead quality and not just volume and cost per lead. Allow four to six weeks before drawing firm conclusions, and check in weekly for early warning signs.
If you run an online store, one technique to test is an asset group that contains only your product feed. That limits the campaign to shopping ads and ads shown to people who’ve already viewed your products, instead of generic display ads across Google’s network.
Guardrails narrow what the automation can do, but they don’t open the black box. You still can’t choose where in Google’s network your budget goes, or which ads reach which people. Google’s channel-level reports now show more of where the spend goes than they used to, and they’re the place to look first when results seem off.
Stop Paying for Searches That Never Become Customers
Every click costs the same, whether it comes from a ready customer or from someone who was never going to hire you. Two settings determine which searches trigger your ad: match types and negative keywords. Both are easy to overlook, and both shape where your budget goes.
Match types control how closely a search has to resemble your keyword before your ad appears. Broad match buys volume, not intent. It shows your ad for anything loosely related, which tends to produce impressive traffic numbers alongside mediocre leads. Phrase and exact match reach fewer searches, but those sit closer to what you’re trying to capture, and a smaller pool of relevant clicks beats a large pool of curious ones.
Looser matching can make sense in a thin market. A niche service in a small town may not generate enough exact-match searches to spend a budget at all, but only if a serious negative keyword list runs alongside it.
Negative keywords do as much work as the keywords you choose. A plumber bidding on “emergency plumber” can end up showing for “plumber salary” or “how to become a plumber.” Neither search will ever bring in a customer, and each costs the same as one that would. Check these categories every month:
- Job-seeker searches. Terms like “salary,” “jobs,” or “how to become” come from people researching the trade, not hiring anyone.
- Free and DIY searches. “Free,” “DIY,” or “how to fix it myself” come from people trying to avoid paying someone.
- Out-of-area searches. Without deliberate exclusions, you can pay for clicks from well outside the area you serve.
- Competitor research. Some searches look up one specific competing business and aren’t looking to hire anyone.
A negative keyword list goes stale if nobody maintains it. Search behavior shifts with news, new laws, and local events, so new irrelevant searches keep appearing. Review the search terms report, the list in your Google Ads account of the exact searches that triggered your ads, on a set schedule, and not only when performance dips.
How your account is organized matters too. One campaign for everything hides your problems. A single campaign covering every service and location averages everything together, so a strong segment and a failing one net out to acceptable numbers and nobody investigates. Splitting campaigns by service, and by area where it applies, shows which combinations work, lets you adjust bids separately, and lets you pause one weak segment without disturbing the rest.
Extensions, which are extra links and buttons added to your ad, make each click do more. A call extension lets someone dial straight from the ad on their phone, which suits an urgent search. Sitelinks send people to a specific service page instead of a generic homepage.
If your account is already a mess, fix it in this order:
- Read the search terms report, which shows what the account is actually buying instead of what it was meant to buy.
- Add negative keywords for the searches that shouldn’t be there.
- Tighten match types.
- Split campaigns where the reports show it’s needed. This is the slowest fix and rarely the right place to begin.
Every dollar saved on a search that was never going to convert is a dollar left for one that might. Tightening these basics makes everything else in the account work harder, without changing a word of your ad.
