What is PPC marketing, and is it worth it for a small business?
PPC (pay-per-click) means you pay each time someone clicks your ad. On Google Search ads, Google's own pricing article says you only pay when a user clicks, and that Google Ads has no flat fees or monthly subscriptions. For a small business, PPC is worth testing when people already search for what you sell and one sale pays for many clicks.
The useful starting numbers come from LocaliQ and WordStream's 2026 search advertising benchmarks (last updated 1 June 2026): an average cost per click of $5.42 across industries, an average Google Ads conversion rate of 8.18%, and an average cost per lead of $66.69. This is vendor data, drawn from thousands of LocaliQ's own customers' campaigns on Google Ads and Microsoft Ads, and a lead there means any contact: a phone call, chat, form fill or email.
If you sell to other businesses and mainly want demo requests, our post on whether Google Ads pays for B2B lead generation covers lead forms and junk leads.
Google Ads, Microsoft Ads, Meta or LinkedIn: which suits a small budget?
Start on Google Search if people search for what you sell. Add Microsoft Advertising once a Google campaign works. Use Meta or LinkedIn when there is little search demand but you can describe exactly who the buyer is. The budget rules below come from each platform's own help pages, checked 5 Nov 2026.
| Platform | What its help pages say about budgets | Our suggestion: use it when |
|---|---|---|
| Google Search | Up to 2 times your average daily budget on a given day; no more than 30.4 times it in a month. No flat fees or monthly subscriptions. | People search for your service or product by name, such as "emergency plumber" plus your town |
| Microsoft Advertising | Monthly limit is the daily budget times the number of days in the month; overspend is usually kept to less than 100% above the daily limit. | You already have a Google campaign that converts and want more search clicks |
| Meta (Facebook, Instagram) | A daily budget is a target over a Sunday to Saturday week. Up to 75% over it on a good day (175% of it at most, or up to 210% with ad set budget sharing on), never more than 7 times it in a week. | Your offer is easy to show in a picture or video and there is little search demand yet |
| Minimum daily budget $10; minimum lifetime budget $100 for new, inactive campaigns. Daily spend can be up to 100% higher than the daily budget, but no more than 7 times it in a week. | Your buyer is defined by job title or company, and one customer is worth a lot |
Sources for the table: Google's spending limits page, the Microsoft Advertising budget guide, Meta's page on daily budgets and LinkedIn's budget help page; LinkedIn's minimums come from its first-campaign guide, linked below.
LinkedIn's first-campaign guide also says Campaign Manager suggests $25 for new advertisers and $50 to $100 for existing advertisers using USD. The page doesn't say whether that is a daily or lifetime figure, so treat it as a default to check, not a rule. LocaliQ's benchmark post notes that you can copy Google Ads campaigns into Microsoft Ads with its import feature.
How do PPC daily and monthly budgets actually work?
Your daily budget is an average, not a ceiling. Google says a campaign might spend up to twice your average daily budget on a given day to take advantage of traffic swings, and that by the end of the month you will have spent no more than 30.4 times it. Plan the month, then divide by 30.4.
- Daily spending limit: 2 times your average daily budget for most campaigns. Google's note says the limit uses the highest average daily budget you chose for that day, so raising and then lowering a budget on the same day still leaves the higher limit.
- Monthly spending limit: 30.4 times your average daily budget (365 days divided by 12). If you change the budget mid-month, spend for the rest of the month won't exceed the new daily budget times the calendar days left.
- Ad scheduling doesn't shrink the month. Per the spending limits page, a campaign with an ad schedule still paces to 30.4 times the daily budget, however many days it is scheduled to run.
- Billing: Google says that even when served costs go above your daily or monthly limits, you never pay more than those limits.
Example: if you set a $32.89 daily budget and run ads on weekdays only, the month has about 21.7 weekdays (30.4 × 5 ÷ 7), so Google paces roughly $1,000 into those days: about $46.08 per active day ($1,000 ÷ 21.7), still capped at $65.78 on any one day (2 × $32.89), by our arithmetic.
Microsoft counts months differently. Its budget guide says the monthly limit is the daily budget multiplied by the number of days in the month. A $32.89 daily budget in a 31-day month allows $1,019.59 ($32.89 × 31). To hold $1,000 in a 31-day month on Microsoft, set $32.26 a day ($1,000 ÷ 31).
Which bidding strategy should a small business start with?
Pick the bid strategy by how many conversions you can measure. Google's Smart Bidding page says you need conversion tracking turned on to use Smart Bidding (Target CPA, Target ROAS, Maximize conversions and Maximize conversion value), and recommends judging results over periods with at least 30 conversions, such as a month or longer (50 conversions for Target ROAS).
The same page also says Smart Bidding can draw on data from all your campaigns, so even new campaigns without data of their own may see better performance. So Google doesn't tell you to wait. The practical problem is the evaluation window: a campaign getting 10 conversions a month needs about three months to reach 30.
| Your situation | Strategy to start with | Why |
|---|---|---|
| Conversion tracking isn't set up yet | Fix tracking first; Maximize clicks in the meantime | Smart Bidding needs conversion tracking |
| Tracking works, fewer than about 30 conversions a month | Maximize conversions, judged over a longer period | Google recommends at least 30 conversions to evaluate |
| 30 or more conversions a month and a cost per lead you can afford | Target CPA | You have enough data to set and judge a target |
| You track the value of each sale (shops, bookings) | Target ROAS, judged over periods with at least 50 conversions | Google's evaluation guide uses 50 for Target ROAS |
If you use Maximize clicks, set a maximum CPC bid limit. Google says it adjusts bids to get as many clicks as possible within your budget, that the limit helps control costs if CPCs run higher than you want, and that a limit set too low can stop the strategy reaching its goal. Give it a few days or weeks, Google says.
Naming note: from June 2026 Google is relabelling "Maximize conversions with a Target CPA" as "Target CPA" (and the same for Target ROAS). Google says the bidding behaviour stays the same.
How do you set up your first Google Search campaign?
Here is the setup checklist, with setting names as they appear on Google's Create a Search campaign help page (desktop web interface, checked 5 Nov 2026). Google notes that new users may see a different onboarding flow, so the screens can differ for a brand new account.
Create the campaign and goal
Go to Campaigns in the Campaigns menu, click the plus icon, then New campaign. Choose Sales, Leads or Website traffic, then select Search under "Select a campaign type". At least one conversion goal is required, even without a goal's guidance.
Set bidding
For leads or sales, focus on Conversions; for traffic, Clicks. Under Show more settings you can set an Ad schedule (say, your opening hours).
Decide on networks
Include Google search partners and Display Network are checkboxes. Our suggestion for a first small campaign: untick Display Network so the budget goes to searches, and add it later as a separate test.
Set locations and location options
Pick your area, or exclude places inside it. Google's location targeting page says broad geo targeting ("Presence or Interest") is recommended as a best practice on Search, but says to consider "Presence" when you only want people in your locations, which fits a business that serves one town. Google doesn't allow radius targeting under 1 km.
Add assets
Sitelink, callout and call assets fill in by default. A local business usually also wants location assets so people can get directions.
Build standard ad groups
Choose Standard (Google suggests it for new users). One ad group per service. Keywords match broadly by default; use quotation marks for phrase match, brackets for exact match, and a minus sign for negative keywords such as -jobs or -free.
Write the ads and publish
Google recommends at least 3 ads per ad group. Enter the final URL, write headlines, and up to 2 lines of description of up to 90 characters. Enter your daily budget, which Google treats as the average to spend each day (your monthly figure ÷ 30.4). Fix anything flagged on the review page (billing, missing keywords, invalid URL), then click Publish.
What does PPC cost per click by industry in 2026?
Cost per click depends mostly on your industry. These are the 2026 averages from LocaliQ's benchmark report for industries where many small, local businesses sit.
| Industry (LocaliQ's category) | Average CPC | Average conversion rate | Average cost per lead |
|---|---|---|---|
| Attorneys & Legal Services | $9.87 | 5.55% | $131.63 |
| Home & Home Improvement | $8.33 | 8.05% | $90.92 |
| Dentists & Dental Services | $8.00 | 10.67% | $72.97 |
| Personal Services | $7.17 | 12.34% | $54.60 |
| Health & Fitness | $6.17 | 6.94% | $67.36 |
| Beauty & Personal Care | $4.62 | 10.35% | $39.25 |
| Automotive: Repair, Service & Parts | $4.35 | 15.51% | $29.96 |
| Real Estate | $3.22 | 3.70% | $102.51 |
| Restaurants & Food | $2.05 | 8.05% | $30.57 |
| All industries | $5.42 | 8.18% | $66.69 |
A cheap click isn't a cheap lead: Real Estate has a low CPC but a high cost per lead, because its conversion rate is 3.70%. Check your own keywords in Keyword Planner before trusting any average.
Worked example: what does $1,000 a month buy?
Here is the arithmetic for a sample business, Northwind Home Repairs (an invented example), spending $1,000 a month on Google Search at the Home & Home Improvement averages above. Replace each number with your own.
Note that the $103.52 cost per lead is higher than LocaliQ's $90.92 for the same industry, because each average in the report is calculated separately, so they don't multiply into each other. If you win fewer than about 17% of leads at $600 a job, this campaign loses money.
To see the whole cost, add the hours you spend on calls and quotes, then put the totals into our CAC calculator, which also works out payback time.
What is a PPC service, and do you need one?
A PPC service is an agency or freelancer who sets up and runs your campaigns for a fee. Google's third-party partner policy says partners should be honest and transparent about their company, services, associated costs and expected results, and requires them to use a separate account for each advertiser they manage. Ask any service to confirm in writing who owns the account, what they charge on top of ad spend, and which conversions they report.
The weekly routine is short: add negatives from the search terms, check calls and forms are counted, and compare cost per lead with what a customer is worth. If your week is full, our weekly marketing system for founders shows where a 30-minute ads check can fit.
And if almost nobody searches for what you sell, PPC has little to buy. Spend nothing yet and work the free channels in our no-budget marketing plan, or go to the people instead. Siela doesn't run ads; its Lead Finder looks for people asking how to solve the problem you solve, or complaining about the tools they use, and contacts them on LinkedIn, X or email. For the map listings and reviews that sit beside your local ads, see our guide to local marketing for a small business.
Frequently asked questions
How much should a small business spend on PPC?
Start from the monthly amount you can lose while you learn, then divide by 30.4 for Google's average daily budget. Check it buys enough clicks to matter: at the 2026 all-industry average CPC of $5.42 in LocaliQ's vendor data, $500 buys about 92 clicks. Keep the test running until you have about 30 conversions to judge.
Can I run Google Ads with $10 a day?
Yes. A $10 average daily budget can spend up to $20 on one day and about $304 in a month. At LocaliQ's 2026 average CPC of $5.42 that is roughly 56 clicks a month, and at the 8.18% average conversion rate about 4.6 leads. That is enough for one tightly targeted local service, not for several.
Is Google Ads or Facebook ads better for a small business?
Google Search reaches people while they search for a service, so it usually suits urgent, local needs like repairs or legal help. Meta ads suit offers that sell on a picture or video when few people search yet. Meta's daily budget can run up to 75% over on a single day, but no more than seven times it across a week.
How long does PPC take to work?
Clicks start once ads are approved and running, but judging results takes longer. Google suggests giving Maximize clicks a few days or weeks, and judging Smart Bidding over periods with at least 30 conversions. A campaign with 10 conversions a month needs about three months to reach that number.
Why did Google charge more than my daily budget?
Google treats the daily budget as an average. A campaign can spend up to twice it on one day when traffic is high, but no more than 30.4 times it over the month, and Google says you never pay beyond those spending limits. Plan from the monthly figure, not the daily one.
