To run Google Ads for a small business, start narrow: one Search campaign on high-intent keywords for the services you actually sell, targeted to the area you serve, with call and form tracking installed before you spend a dollar. Then use the first 30 days to cut the searches you do not want to pay for. According to the 2026 LocaliQ and WordStream benchmarks, Google Ads search campaigns turn 8.18% of clicks into conversions on average, at an average cost per lead of $66.69, so a tight setup usually pays off faster than a bigger budget.

This guide is the how-to. If your main question is the price, read our breakdown of what Google Ads costs a small business, with management fees and budget sizing.

Step 1: Create the account in your own name

Sign up at ads.google.com with a Google account your business controls, ideally on your business email. Google's sign-up flow asks for your business name and website, lets you link your Google Business Profile and YouTube channel, and offers to create the account without a campaign. Take that option: Google itself recommends creating the account before the campaign, and it keeps you from launching a half-configured campaign in the middle of sign-up. Then add billing: country, time zone, payment profile and payment method.

If someone runs the account for you, they should be given access to your account, never the other way around. At Discovery Digitals, every account we manage stays in the client's name, with no long-term contract.

Step 2: Set up conversion tracking before launch

Conversion tracking records the valuable actions people take after interacting with your ad. For a local business, that means:

  • Calls placed directly from the ad.
  • Calls to the phone number shown on your website.
  • Quote requests and contact forms.
  • Online bookings, if you take them.
  • Later, offline conversions such as qualified leads or signed jobs, imported from your CRM.

Google measures website actions with the Google tag or Google Analytics, tracks calls from ads and from your site, and imports offline conversions from files or an API. Check the setup with Google Tag Assistant: a new conversion action can show as Unverified or Inactive until it records a first conversion or a successful test.

Count only real leads as primary conversions. A visit to the contact page or a click on your email address is not a lead, and if you tell Google it is, Smart Bidding will find you more of the wrong thing.

Step 3: Search, Performance Max or Local Services Ads?

Campaign typeWhere it showsHow you payBest for
SearchGoogle search results, on the keywords you choosePer clickThe first campaign of almost every local service business
Performance MaxYouTube, Display, Search, Discover, Gmail and Maps, from one campaignBids toward your conversion goals across all channelsAccounts with steady, reliable conversion data
Local Services AdsTop of local results, with a Google Verified badgePer leadEligible trades and professions that pass Google's screening

Performance Max needs text, images, logos and videos, and it optimizes toward the conversion actions you define, which is why it struggles on a new account with no data. Google notes that Search campaigns with an exact match keyword are prioritized over Performance Max when the search matches, so the two can run side by side later.

Local Services Ads work differently: you set a budget, a service area and your services, pass Google's screening and verification (which includes business registration and identity checks), and pay only when a customer contacts you through the ad. For most small local businesses, the right order is Local Services Ads if your category is eligible, plus a Search campaign, and Performance Max only once the account converts reliably.

Step 4: Choose keywords and match types

Start from what customers type when they are ready to buy: a service plus a city (“water heater replacement denver”), a service plus urgency (“emergency plumber”), or a service plus “near me”. Group keywords by service, one ad group per service, so the ad and the landing page match the search.

  • Broad match, written with no symbols, is the default for every keyword. It can show your ad on related searches that do not contain your words. Google says it is critical to use Smart Bidding with broad match.
  • Phrase match, written “in quotes”, shows on searches that include the meaning of your keyword, including more specific searches.
  • Exact match, written [in brackets], shows on searches with the same meaning or intent as your keyword.

On a small budget, start with phrase and exact match on a few dozen keywords at most, and test broad match only once Smart Bidding has real conversions to learn from.

Step 5: Add negative keywords before you launch

Negative keywords exclude searches you do not want to pay for. Start every local account with lists like these:

  • Jobs: jobs, hiring, salary, career, apprenticeship.
  • Learning and DIY: how to, DIY, course, school, training, certification.
  • Freebies: free, coupon, and “cheap” if it does not fit your positioning.
  • Supplies: parts, supply, wholesale.
  • Places you do not serve, by city name.

Google points out that negative keywords do not match close variants, so you must add singulars, plurals and synonyms yourself, and that using too many can shrink your reach. Review the search terms report at least once a week and keep adding.

Step 6: Write ads that earn the click

Search campaigns use responsive search ads: you give Google up to 15 headlines of 30 characters and 4 descriptions of 90 characters, and it combines them for each search. The minimum is 3 headlines and 2 descriptions; get close to the maximum so Google has real options.

  • Service and city: “Water Heater Repair in Denver”.
  • Proof, if it is true: years in business, review rating, license.
  • Offer: free estimate, same-day service, upfront pricing.
  • Call to action: “Call Now”, “Book Online”.

Add assets: a call asset, a location asset linked to your Google Business Profile, sitelinks to your main service pages and callouts such as “24/7” or “Financing available”. Then send each ad group to the matching service page, with the phone number visible and a short form: here is what makes a landing page convert.

Step 7: How much should you spend on Google Ads?

Spend enough to collect meaningful data in the first month, and no more than you can afford to learn with. The cleanest method works backward from leads: leads wanted per month times the average cost per lead in your industry. At the 2026 benchmark averages, $1,000 a month buys roughly 11 leads in home services, 14 for a dental practice and 8 for a law firm (see the table below).

At Discovery Digitals, we recommend an ad budget starting at €900 a month for a local business: below that, data comes in too slowly to optimize. Run your own numbers in our free Google Ads budget calculator, then enter a daily budget equal to your monthly budget divided by 30.4, the average number of days in a month.

For bidding, use Maximize conversions once tracking works. On a brand new account where conversions are still rare, a common approach is to start with Maximize clicks and a maximum cost per click for a few weeks, then switch.

Step 8: What to do in the first 30 days

  1. Day 1: send a test lead through every path (call, form, booking) and confirm each conversion records.
  2. Days 2 to 7: check the search terms report every two or three days and add negatives. Do not restructure: Google says the Learning status disappears within 7 days, and performance typically takes 1 to 2 conversion cycles to stabilize.
  3. Week 2: pause keywords that spend without leads, see which headlines Google favors, and limit the ad schedule to the hours someone answers the phone.
  4. Week 3: listen to calls and read the forms. Mark junk leads, tighten locations and services.
  5. Week 4: compare your cost per lead with your target. Google notes that budget changes take effect immediately without triggering a new Learning status, so raise the budget gradually on what works.

2026 search advertising benchmarks by industry

LocaliQ and WordStream publish the most widely used public benchmarks, built from thousands of customer campaigns on Google Ads and Microsoft Ads. Their 2026 report, last updated June 1, 2026, gives these averages for the trades covered in this guide:

IndustryClick-through rateConversion rateCost per clickCost per leadLeads per $1,000
All industries6.64%8.18%$5.42$66.69About 15
Home and home improvement6.47%8.05%$8.33$90.92About 11
Dentists and dental services5.66%10.67%$8.00$72.97About 14
Attorneys and legal services5.87%5.55%$9.87$131.63About 8

The last column is $1,000 divided by the average cost per lead, rounded. The same report notes that cost per lead decreased across industries for the first time in five years. Treat these figures as a sanity check, not a forecast: your city, your offer and your landing page move them a lot.

Google Ads for plumbers and HVAC companies

Plumbing and HVAC searches are urgent and mostly mobile: a burst pipe or a dead AC unit means a phone call within minutes. What changes:

  • Calls first. Call assets on every ad, call tracking on the site, and an ad schedule that matches the hours you really pick up.
  • Split emergency from planned work. “Emergency plumber” and “water heater installation” deserve separate ad groups, ads and budgets.
  • Plan for seasons. HVAC demand swings between cooling and heating, so shift budget between services through the year.
  • Add Local Services Ads. Plumber, HVAC and drain expert are all eligible categories in the US.

On a plumbing account we manage, €6,200 of ad spend produced 8,210 clicks and 3,820 conversions, or €1.62 per conversion. For more on trades, see how our Google Ads management works.

Google Ads for contractors and roofers

Contracting and roofing jobs are worth far more than a service call, and the decision takes longer, so the game is lead quality, not volume:

  • Qualify in the form: project type, timeline, zip code and, for roofers, whether an insurance claim is involved.
  • Import offline conversions (qualified lead, signed job) so bidding learns which clicks become contracts.
  • Show the work: landing pages with project photos, reviews and license information.
  • Use Local Services Ads where eligible: general contractor, roofing, siding, flooring and many other home services are on Google's list.

Results on accounts we manage show the range. A roofing company in a premium market got 6 qualified requests in 4 weeks at €269 per qualified lead. A carpentry business reached a 5.5x return on ad spend (€152,000 for €27,500) at an average cost per click of €1.06, and an electrical contractor a 3.0x return (€40,200 for €13,600, with 860 conversions).

Google Ads for dentists

Dental searches convert well: 10.67% on average in the 2026 benchmarks, the best of the four industries in the table, for $72.97 per lead. What changes:

  • Separate high-value treatments (implants, clear aligners, veneers) from checkups and emergencies, each with its own landing page.
  • Emergency dentist searches need same-day messaging and an ad schedule that matches your availability.
  • Insurance and financing are part of the decision: say which plans you accept and whether you offer payment plans.
  • Track online bookings as conversions, not just calls.
  • Local Services Ads are open to dentists and orthodontists in the US.

Health is also one of the sensitive interest categories in Google's personalized advertising policy, so check that policy before you build remarketing audiences. Search intent does most of the work for a practice anyway.

Google Ads for lawyers

Legal is the most expensive of the four: $9.87 per click and a 5.55% conversion rate add up to $131.63 per lead. Every click has to count:

  • One campaign per practice area, on phrase and exact match: “personal injury lawyer [city]”, “dui attorney near me”.
  • Heavy negatives: free legal advice, pro bono, legal aid, paralegal, law school, lawyer salary.
  • Intake is part of the campaign. Answer calls fast, after hours too, and import signed cases as offline conversions.
  • Local Services Ads cover many practice areas in the US, including personal injury, family, criminal, DUI, estate and immigration law.
  • Ad copy must also respect your state bar's rules on lawyer advertising.

Mistakes that burn small business budgets

  1. Leaving every keyword on broad match, the default, without Smart Bidding, conversion data or negative keywords.
  2. Launching without conversion tracking, or counting page views and email clicks as leads.
  3. Reaching people outside your area. Google's location options include “Presence”, which targets people in or regularly in your locations, and its help page says Presence makes sense when you only want to reach users there.
  4. Sending every click to the homepage instead of the matching service page.
  5. Starting with Performance Max on a new account with no conversions to learn from.
  6. Changing everything every few days while the campaign is still learning.
  7. Never opening the search terms report, the only place that shows what you actually paid for.
  8. Running ads when nobody answers the phone, then blaming the leads.
  9. Letting a provider own the account, and losing your history and data when you leave.
