How Google Ads works
Google Ads is an auction that runs every time someone searches. You choose the searches you want to show up for, set what you’re willing to pay for a click and write the ad. You pay only when someone clicks.
The highest bid doesn’t automatically win. Google also weighs how relevant and useful your ad and landing page are to that search, and how likely people are to click. A tightly built campaign can outrank a competitor with a bigger budget and pay less per click doing it.
The appeal is intent. Someone searching “emergency plumber near me” wants to hire right now, and an ad puts you in front of them today instead of after months of SEO. The catch is that you pay for every click, whether the page it lands on converts or not, so efficiency is everything.
When Google Ads make sense, and when they don’t
Good times to run ads
- People search for what you sell when they’re ready to buy
- A customer is worth enough to pay for several clicks to win one
- You need leads now, while SEO builds
- You’re launching or testing a new service, offer or area
- You want to fill a slow season
When to wait
If your website can’t convert visitors, or you can’t track which clicks become leads, fix those first. Ads amplify whatever’s already there, including the leaks. That’s why we don’t run ads for a client until the page they’ll land on converts and the tracking is tested.
Campaign types
Search
Text ads on the results page for the searches you choose. They carry the highest intent, and for most local service businesses they’re the right place to start.
Local Services Ads
For many home service, legal, health and professional categories, these appear at the very top of results with a verification badge, and you pay per lead rather than per click. They require passing Google’s screening, like license, insurance and background checks, which is part of why people trust them. If your category qualifies, they’re often the first paid channel worth turning on.
Performance Max and Display
Google places your ads across Search, YouTube, Maps, Gmail and partner websites, largely automatically. They can work well once you have solid conversion data to guide them, but they’re harder to control and easy to waste money on early.
Remarketing
Most visitors don’t contact you on their first visit. Remarketing shows ads to people who visited your site and left, keeping you in mind while they decide. For planned, higher-priced purchases, it’s often one of the most efficient uses of a small budget.
Setting up Local Services Ads
If your category qualifies, Local Services Ads are worth setting up before or alongside Search campaigns. The process is different from regular Google Ads:
- Check eligibility. Enter your business category and location on Google’s Local Services Ads site to see if it’s offered where you work.
- Build the profile. Services, service areas, hours and a budget. Pick only the job types you actually want, because you pay for leads in every one you select.
- Pass verification. Depending on the category, expect license and insurance checks and background checks for owners and field workers. Have documents ready, because this is where most setups stall.
- Connect reviews. Your Google reviews show on the ad, which is one more reason to keep them coming.
- Answer fast and manage leads. How quickly and reliably you respond affects how often your ad shows. Mark lead outcomes, and dispute leads that don’t fit the guidelines.
Because you pay per lead, the numbers are simpler to judge: divide what you spent by the jobs you won.
Keywords and match types
Keywords are the searches you want to show up for. Choose ones with buying intent: the service plus the city, “near me,” “repair,” “cost,” “emergency,” “install.” Match types control how loosely Google interprets them.
Beginners lose the most money to broad match running without supervision. Start with exact and phrase match on your highest-intent terms. Broad match can find valuable new searches later, but only once strong conversion tracking is guiding Google’s bidding.
Group keywords tightly. An ad group about “roof leak repair” should contain only leak repair searches, with ads about leak repair, sending clicks to a page about leak repair. That match is what earns better positions at lower cost.
A simple account structure that works
Messy structure is behind a lot of wasted spend. A clean starting structure for a local service business looks like this:
- One campaign per main service line with its own budget, like “Roof repair” and “Roof replacement,” so the more profitable service doesn’t get starved by the other.
- Tight ad groups inside each campaign by specific need: “leak repair,” “storm damage,” “shingle repair.”
- Five to fifteen closely related keywords per ad group, not fifty loosely related ones.
- Ads written for that ad group, using its words.
- A landing page for each service line, or better, for each main need.
- Shared negative keyword lists applied across every campaign.
Keep a separate campaign for your own business name if competitors bid on it. Brand clicks are cheap and convert well, and mixing them into service campaigns makes those campaigns look better than they are.
Negative keywords
Negative keywords stop your ads from showing for searches you don’t want. A solid, growing list is one of the biggest levers for cutting wasted spend.
- Job seekers: jobs, careers, hiring, salary, training
- Do-it-yourselfers: DIY, how to, tutorial, parts
- Bargain hunters you can’t serve: free, cheap, used
- Services you don’t offer, and places you don’t serve
Then check the search terms report every week at first. It shows what people actually typed before clicking your ad, and it’s almost always surprising. Add anything irrelevant as a negative, and add any valuable new searches as keywords.
Writing ads that get clicked
Your ad decides whether a ready-to-buy searcher clicks you or the competitor above or below you. Better ads also improve quality, which lowers what you pay.
Match the search
Put the searcher’s words in the headline so the ad mirrors what they typed. Someone searching “water heater replacement Troy” should see those words.
Lead with what they want
Same-day service, free estimates, upfront pricing, weekend appointments, licensed and insured. Only use the ones that are true. Speak to what the customer wants, not just what you do.
Add proof and a clear action
Ratings, years in business you can back up, guarantees you actually offer, then a specific action: “Call for a free quote,” “Book online today.” Write several versions. Small wording changes can move click rates noticeably, and Google will show you which ones win.
Use every asset
Assets (formerly called extensions) make your ad bigger and more useful at no extra cost: sitelinks to key pages, short callouts like “Locally owned,” a call button, your location and structured snippets listing your services. Set them up on every campaign.
Landing pages
The fastest way to waste ad spend is sending clicks to your homepage. Send each ad group to the page about exactly that service, built to turn a visitor into a call or booking.
What a good ad landing page has
- A headline that matches the ad and the search
- What the service is, who it’s for and how soon you can help
- Proof close to the ask: reviews, photos of real work, results
- One clear call to action, repeated down the page, with click to call on phones
- Pricing guidance or an honest explanation of how you price
- A fast load on a phone, because you’re paying for every visitor
- Few distractions, so people don’t wander off after you paid for the click
The conversion optimization guide goes deeper on building pages that convert.
Conversion tracking
If you can’t see which clicks become leads, you can’t tell good campaigns from bad ones, and Google’s automated bidding optimizes for clicks instead of customers. Set up conversion tracking before you spend real money.
Track form submissions, calls from the ad’s call button, calls from the website and bookings. Then test each one yourself: submit the form, place a test call, confirm the conversion shows up. When someone says “Google Ads didn’t work for us,” the real story is often that nobody could see what was working.
Go one step past leads when you can. Importing which leads became paying customers, even roughly, lets you judge campaigns by revenue instead of form fills.
Budgets, bidding and scaling
Setting a budget
Work backward from what a customer is worth. If a new customer is worth $2,000 to you and about one in four leads becomes a customer, you can afford a meaningful amount per lead and still profit. Then set a monthly budget that buys enough clicks to learn something, focused on your best service in your best area. A small budget spread across many services and cities learns nothing.
Bidding
While data is thin, use more manual control or simple click-focused bidding with a sensible cap. Once conversions come in steadily, move to conversion-based bidding so Google can aim for leads. Changing bidding strategies too often resets the learning, so give each change time.
Scaling
Scale what’s working: raise budget on campaigns with the best cost per customer, then expand to the next service or area one at a time. Add remarketing to bring back visitors who didn’t call. If cost per lead climbs sharply when you scale, you’ve reached the edge of the profitable searches for now.
Seasonality
Most local businesses have busy and slow seasons, and search volume follows them. Furnace repair spikes with the first cold week, roofing after storms, landscaping in spring, gift cards before the holidays. Plan budget changes a few weeks ahead of the season rather than reacting after it starts, and write ads for what people need right then. In slow months, ads can fill the calendar with maintenance work, inspections or off-season offers, as long as the cost per job still makes sense. Keep last year’s monthly numbers handy, because the best predictor of next October is usually this October.
Location targeting and ad scheduling
Locations
Target the cities, ZIP codes or radius you actually serve, and nothing more. Check the location setting that decides whether Google shows ads to people who are in your area or merely interested in it. For most local businesses, people physically in or regularly in your area are the right choice, or you pay for clicks from people planning trips.
Look at results by location after a few weeks. Some towns will convert far better than others, and you can raise or lower bids for each.
Schedule
If you can’t answer the phone at 11pm, think about whether ads should run then. Some businesses do well sending after-hours clicks to online booking or a form. Others waste money on calls nobody answers. Look at conversions by hour and day, then set the schedule and bid adjustments to match when leads actually turn into jobs.
Devices
Most local service searches happen on phones, and phone clicks often turn into calls. Make sure the phone experience converts before deciding whether to raise or lower mobile bids.
Managing the account week to week
Google Ads rewards ongoing attention. A simple routine keeps an account healthy:
- Weekly: review search terms, add negatives, check that conversions are still recording, and look for sudden cost jumps
- Every two weeks: pause keywords and ads that spend without converting, and shift budget toward what converts
- Monthly: compare cost per lead and cost per customer by campaign, test new ad copy and review the landing pages
- Quarterly: revisit budget, locations, services and whether new campaign types make sense
Be careful with the recommendations Google shows inside the account. Some are useful. Many increase spend or loosen targeting. Auto-applying them without review is a common way accounts drift into waste.
Metrics that matter
- Cost per lead and cost per customer. The numbers that decide whether ads are profitable.
- Conversions. The leads themselves, not clicks.
- Conversion rate. How well clicks become leads, which flags landing page or targeting problems.
- Search terms. What people actually searched, the source of negatives and new keywords.
- Impression share. How often you showed when you could have, which tells you whether budget or quality is limiting you.
Click-through rate and impressions are diagnostic, not goals. If cost per customer is healthy and steady or falling, the account is winning, whatever the other numbers say.
Google Ads and the rest of your marketing
Google Ads is unmatched for catching existing, ready-to-buy demand fast, and for testing which offers and messages convert before you invest in them elsewhere. The limit is that the leads stop the moment spending stops.
That’s why ads work best on top of a foundation that builds over time. Local SEO and useful content bring leads you don’t pay per click for. A website built to convert makes every ad dollar go further. Reviews lower the cost of every channel by making people choose you. For most local businesses the right mix is Local Services Ads and Search for leads now, pointed at pages built to convert, while SEO grows the share of leads that arrive without a click cost. See the local SEO guide.
Costly Google Ads mistakes
- No conversion tracking, or tracking that was never tested
- Sending clicks to the homepage instead of a matching page
- Broad match with no negatives and nobody watching
- Optimizing for clicks instead of leads and customers
- A small budget spread across too many services and areas
- Targeting a whole state when you serve three counties
- Auto-applying Google’s recommendations without review
- Setting it up once and never managing it
- Judging the account in the first week, before it has data
Running it yourself or hiring help
A simple, single-service campaign is learnable. But the platform is built to spend money, and many defaults favor reach over efficiency. Once spend is meaningful, experienced management often pays for itself in lower cost per lead and less wasted budget.
Whoever runs it, insist on three things: the ad account is in your name, conversion tracking is real and tested, and reporting is in leads, cost per lead and customers rather than clicks and impressions.
