Search engine marketing is paying to appear when someone nearby searches for what you sell. That’s the whole idea, and for most small businesses it means Google Ads.
Search engine marketing for local business gets wrapped in jargon, so here it is plainly: what it covers, why it suits a company with a service area, what a campaign is made of, what the current benchmarks say a lead costs, and where the money tends to leak.
What search engine marketing for local business covers
Search engine marketing, or SEM, has four parts:
- Paid search ads
- Keywords chosen for your services and your towns
- A decision about which areas the ads appear in
- Regular adjustment once you can see what the ads bring in
The aim isn’t traffic. It’s calls, form submissions and direction requests from people who need the service and live where you work. If you’d like the fuller picture, our search engine marketing page lays out how we run it.
SEM gets confused with SEO, and the confusion usually starts because some people use SEM for everything related to search. As we use it here, SEM is the paid placements. SEO is earning a place in the unpaid results and on Google Maps through your website, your Google Business Profile and your reviews.
The practical difference is time and cost. Paid ads can start bringing inquiries once the campaign and the page are ready, and they stop when the budget stops. SEO doesn’t charge per click, but it usually takes longer to show movement. Plenty of businesses need some of each, and we compare them in our article on SEO vs Google Ads for contractors.
Why it suits a business with a service area
Think about a septic company in Harleysville. Nobody has to persuade a homeowner with a slow drain and a wet patch in the yard that she needs help. She types a few words and calls the first reasonable company. The ad only has to be there at that moment.
Two features of the platform fit a business like that. The first is where the ads show. According to Google Ads Help on location targeting, the locations you choose can include countries, areas within a country, and a radius around a location. You can also exclude areas you don’t serve. The second is what you pay for. Google’s definition of cost-per-click bidding is that you pay for each click on your ads, up to a maximum you set, and you’ll often be charged less than that maximum.
Calls and forms can be traced back to the ads, where tracking is set up. That’s what turns the spending into something you can judge.
What a campaign is made of
A campaign has four working parts, and each can go wrong on its own.
Keywords. These are the searches you want the ad to appear for. “Septic pumping Harleysville” tells you a lot about the person: what she needs, where she is, how soon. Just as important are the searches you don’t want. If your ad keeps showing for people hunting septic jobs or watching do-it-yourself videos, each click costs money and none is a customer. A list of excluded terms, called negative keywords, is how that gets fixed.
Ad copy. An ad has a small job: tell the searcher you do the thing they searched for, in the place they need it. Plain wording that names the service and the town does that better than a slogan.
The landing page. This is where the click arrives. Picture clicking an ad for tank pumping and landing on a home page that lists every service the company offers. Many people won’t hunt for the part that applies to them. A page that loads quickly, matches the ad, explains the service and makes calling easy gives the click a fair chance. We’ve collected more in our landing page tips for small businesses.
Ongoing adjustment. A campaign isn’t finished when it launches. Keywords get pruned, budgets get moved, and the tracking gets checked against what happened in the business. In our experience, most of the improvement in cost and lead quality comes from this unglamorous part.
What does it cost, and is it worth it?
It can be expensive, and it doesn’t have to be. LocaliQ’s 2026 search advertising benchmarks, drawn from thousands of its customers’ Google Ads and Microsoft Ads campaigns, put the average cost per click across all industries at $5.42 and the average cost per lead at $66.69. Those are averages across many industries, and LocaliQ notes that budget, location and keywords all change the result. Your trade and your towns may sit well above or below them.
What matters is the comparison with what a job is worth. A lead at that price is cheap for a full system or a big install, and expensive for a small repair. We think the average is the least useful number on the page. Your own cost per good inquiry is the one to watch.
Paid search tends to fit when:
- People already search for what you do, often with some urgency
- You serve a defined area
- You have room to take on the work
- A typical job is worth enough to cover the cost of the leads
It fits less well when hardly anyone searches for the service, or when each job is worth too little.
Where the money leaks after the click
Ads can appear soon after a campaign goes live, but good results usually take longer. The early weeks show which searches bring worthwhile inquiries and which only bring clicks.
Ads without a plan for which work you want also tend to bring the wrong calls. Say the septic company runs ads and the phone rings more. Are the calls about pump-outs in Harleysville, or people two counties away asking for a price? A plan decides which one you get.
Then there’s the phone. Who answers when the ad works? How fast does someone reply to a form? If a good call goes to voicemail, the budget paid for an introduction nobody was there for.
Plenty of owners set up Google Ads themselves, and some do fine. What takes time is building it so the money goes to the searches you want, then reading the results every few weeks. Whoever runs your account, ask two things. Can you see which searches the money went to? And who owns the account if you part ways?
There are limits. Nobody controls what a click costs in your market or what competitors decide to bid, and we can’t promise a set number of calls by a set date. Your part is telling us which inquiries became paying work. We can track calls and forms where the tools allow it, but only you know the rest. That feedback lets us move budget toward the searches worth paying for, and it’s the basis for knowing whether your marketing is working. The ad spend is also separate from the cost of managing the campaign, and we explain both before you decide anything.
Call your own number first
This week, call your business line from your cell phone at a time when you’d expect ads to be working, such as an early evening. Note how many rings it takes, who answers, and what they say. It takes five minutes and costs nothing. If the answer is voicemail, fix that before you spend on clicks.
Then tell us what work you want more of, what you’ve tried, and what happened. If you’re running ads now, show us the account and the pages they point to. We’ll look at where the budget is going and tell you what we’d change. Your first consultation is free. When you’re ready, send us a message and we’ll set up a time to talk.
