How Do Google Ads Work? A Plain Guide for Canadian Small Businesses

Google Ads is Google’s online advertising program, which lets a business show ads on Google Search, YouTube, Gmail, Maps and millions of partner websites and apps. So how do Google Ads work in practice? You pick a campaign type, the searches or audiences you want to reach, a daily budget and a bid. Every time someone searches, Google runs an auction among the eligible ads and ranks them by Ad Rank, which combines your bid with the quality of your ad and landing page and the context of that search. On most search campaigns you pay only for clicks, and often less than your maximum bid.

This guide explains each piece as Google currently documents it, including what Quality Score does and does not do, since several popular explanations describe rules Google has changed. It then covers billing, a first-campaign setup order and the settings a Canadian small business should get right before spending a dollar.

Where Google Ads show, by campaign type

The campaign type decides where your ads can appear and what they look like, so it is the first real decision in any account. These are the types a small business will actually meet.

Local Services Ads, the listings that can appear prominently at the top of Google search results for trades and some professional services, are a separate program. They charge per lead rather than per click, with screening that varies by category and country, so check the Canadian requirements for your trade first.

How the Google Ads auction works: Ad Rank and Quality Score

Every search triggers a fresh auction, and Google actually runs a separate auction for each ad location on the page, so the ads above the search results are chosen in a different auction from the ones lower down. Your ad can appear only once in any one location, although it can show in more than one location on the same page. In each auction, Google calculates your Ad Rank twice, first to decide whether your ad is eligible to show at all and then to decide where it ranks against the other eligible ads. Because the competition, the searcher and your ad quality change from one search to the next, Google says some movement in your ad’s position, and in whether it shows at all, is normal.

The six factors behind Ad Rank

According to Google Ads Help (“About Ad Rank”), Ad Rank rests on six factors. Your bid is the most you are willing to pay for a click, and the quality of your ad and landing page reflects how relevant and useful they are to that particular search, measured at the moment of the auction through signals such as expected clickthrough rate, ad relevance and landing page experience. Ad Rank thresholds set the minimum an ad must reach before it can show, while the competitiveness of the auction matters because two ads with similar Ad Rank have a similar chance at the same spot, and a wider gap makes the higher one more likely to win. The context of the search counts too (the words, the person’s location and device, the time and the other ads and results on the page), and so does the expected impact of your assets, such as a phone number or extra links under the ad.

Google’s own simplified example shows how the thresholds work. Suppose seven advertisers have Ad Ranks of 80, 50, 30, 10, -10, -30 and -35, the minimum needed to show anywhere on the page is 0, and the minimum needed to show above the search results is 40. The three advertisers below zero cannot show at all, the two at 80 and 50 qualify for the top positions, and the two at 30 and 10 can still appear lower on the page. The numbers are Google’s illustration rather than values you will see in your account, but the logic explains why better quality or a higher bid can lift an ad from the bottom of the page into the top block, and why an ad that misses the threshold does not show no matter how much budget is left.

What Quality Score is, and what it is not

A widely repeated explanation says that Ad Rank is your bid multiplied by your Quality Score, and some current guides still list Quality Score as one of Ad Rank’s ingredients. Google’s Help page on Quality Score says otherwise: it “is a diagnostic tool” and it “is not an input in the ad auction.” The 1 to 10 score, shown for each keyword, summarizes three components (expected clickthrough rate, ad relevance and landing page experience), and each one is rated “Above average”, “Average” or “Below average” against other advertisers whose ads showed for the exact same search over the last 90 days. The live auction uses its own measures of those same qualities at the moment of each search, so the score is best read as a report on how your ads and landing pages compare, not as a number that sets your position.

Using it well is mostly a matter of reading the components. You can add the Quality Score columns to the keywords table in your account, and in practice a “Below average” rating points to the fix: a weak expected clickthrough rate usually calls for stronger ad copy, weak ad relevance for tighter ad groups whose ads match the keyword, and a weak landing page experience for a page that answers the search. A dash in the column means there have not been enough searches that exactly match the keyword to calculate a score, and changing a keyword’s match type does not change its Quality Score, because the score is built from exact searches. Google also says Quality Score “is not a key performance indicator”, so it is worth checking when a keyword underperforms but not worth chasing for its own sake.

What you actually pay for a click

With Manual CPC, your maximum cost per click is normally the most you will be charged for a click, and the actual charge is often lower. Google Ads Help (“Actual cost-per-click”) explains that you pay only what is needed to clear the Ad Rank thresholds and beat the Ad Rank of the advertiser directly below you, or the reserve price if nobody below you clears their thresholds, and that the advertisers further down can influence your price as well. Thresholds are typically higher for ads above the search results, so a top position usually costs more per click. Google publishes no formula for the calculation, which means the often-quoted rule “the Ad Rank of the advertiser below divided by your Quality Score, plus one cent” is not Google’s method. Bid adjustments can lift a click above your maximum, and automated bid strategies set their own bid in each auction.

That is why a higher bid does not automatically win the top spot, and why a strong ad can sometimes pay less than a weaker competitor. Google’s auction glossary says that even when a competitor bids more, highly relevant keywords and ads can still win a higher position at a lower price, and its Ad Rank page adds that “higher quality ads can often lead to lower CPCs.” A relevant ad and a landing page that matches the search are therefore usually worth more than trying to outbid everyone, although every auction plays out differently. For a small business up against bigger budgets, that is the most useful thing to know about the auction, because quality is the part it can control.

Keywords, match types and the searches you pay for

On a Search campaign, keywords tell Google which searches your ad may enter, and match types control how loosely Google interprets them. Exact match stays closest to the meaning of the keyword, phrase match allows more variation around it, and broad match lets Google show your ad on a much wider range of related searches. Google’s own keyword guidance says it is “critical to use Smart Bidding with broad match”, so a campaign that starts on manual bidding is much easier to control with phrase and exact match.

Keyword Planner, built into Google Ads, suggests related keywords and estimates their monthly searches and what a keyword’s clicks are likely to cost. Google notes that real results also depend on your bid, budget, ad quality and location targeting, so treat the figures as a guide to relative demand rather than a forecast, and set the location to the area you serve, such as Calgary, rather than reading national figures.

Negative keywords do the opposite, keeping your ad out of searches you do not want to pay for. A Calgary furnace repair company, for example, might exclude “jobs”, “salary” and “parts wholesale” to avoid paying for job seekers and other contractors. Google documents one trap here: negative keywords do not match close variants. Excluding “flowers” as a negative broad match keyword blocks “red flowers” but not “red flower”, so singular and plural forms often need to be added separately.

The search terms report shows the actual searches that triggered your ads, although Google leaves out some low-volume terms for privacy reasons, so you see many of the real searches behind your spend rather than every one. The practical recommendation from SEO Company To-The-TOP! is to read it weekly during a new account’s first month, because it is the quickest way to spot wasted spend and new negatives.

Bidding: manual and automated options

Your bid strategy tells Google what to optimize for. With Manual CPC you set the maximum cost per click yourself, while the automated strategies include Maximize clicks, Maximize conversions, Target CPA (a target cost per conversion), Maximize conversion value, Target ROAS (a target return on ad spend) and Target impression share. The conversion-based ones form what Google calls Smart Bidding, which sets a bid for each auction using signals such as device, location and time.

One older option has gone. Enhanced CPC, which let Google nudge manual bids up or down, stopped being available for Search and Display campaigns in the week of March 31, 2025, and campaigns left on it now effectively run on Manual CPC, so guides that still recommend it are out of date.

Smart Bidding can only optimize toward what it can measure. Google says you can turn it on without prior data, and that it can draw on your other campaigns, but it requires conversion tracking and recommends certain conversion volumes for best results. Where tracking is unproven, To-The-TOP!’s cautious approach is Manual CPC or Maximize clicks on a tight Search campaign with phrase and exact match, moving to a conversion-based strategy once leads are recorded properly. That is a practitioner preference rather than a Google rule, and an account with sound tracking and a clear goal can reasonably start on Maximize conversions. Either way, Google frames a new Smart Bidding strategy’s adjustment period in conversion cycles, so a business whose customers take weeks to decide needs more patience than one that takes calls the same day.

What Google Ads costs and how billing works

There is no fixed price for Google Ads. Each auction sets the cost per click, so it varies by industry, keyword, city and time of day, and fields with high-value customers, such as law or insurance, can be far more competitive than local retail. A separate guide to how Google Ads costs, bids and budgets fit together walks through the numbers.

What you control directly is the average daily budget. According to Google Ads Help, a campaign can spend up to twice its average daily budget on a busy day, but by the end of the month it will have spent no more than 30.4 times the daily figure. As an illustrative example, a Calgary business with a $20 daily budget could see $40 spent on a strong Tuesday, but would not be billed more than $608 for the month (30.4 x $20). At an illustrative $4 a click, that buys roughly 150 clicks a month. Whether $20 a day or $500 a month is enough therefore depends on how many clicks it buys at your trade’s prices and how many become enquiries, not on the number itself.

Charges depend on the payment setting (postpay, where Google charges after your ads run; prepay, where you add money first; or monthly invoicing), and not every option is offered in every country. On postpay, Google charges you whenever your costs reach your payment threshold and again on the first day of each month, so you may be charged several times in one month. A round charge such as $500 normally covers costs already accrued, plus any applicable taxes, rather than a separate fee; your billing summary shows your own threshold.

To turn a budget into an expectation, divide it by a realistic cost per click and then apply your landing page’s likely conversion rate; the Google Ads cost calculator on this site gives a starting estimate of ad costs for your business type and city to test that arithmetic against. If that comes to only a handful of clicks a week, the campaign may take too long to judge, and narrowing the keywords or area is often better than spreading a small budget thinly.

What has changed in Google Ads recently

Several formats in older explainers are being retired or folded into newer campaign types. Each item comes from the relevant Google Ads Help page, last verified on October 30, 2026, and Google can move these dates.

Setting up a first campaign, in order

Google’s guided setup asks for much the same information, but the order below is To-The-TOP!’s suggestion, because it settles tracking and targeting before any budget goes live.

1. Create the account and confirm the billing country, time zone and currency (Canadian dollars, if that is what you want), since the currency is permanently set when the account is created.
2. Decide what counts as a conversion for your business (a phone call, a form or a booking) and set up tracking for it.
3. Choose a goal and a campaign type. For most service businesses that means Search.
4. Set the locations and language, using “Presence” for a business that only serves its own area.
5. Add keywords in tight groups by service, with phrase or exact match to start, plus a first list of negative keywords.
6. Write a responsive search ad for each group and add assets such as your phone number, sitelinks and location.
7. Set the average daily budget and the bid strategy.
8. Review the ad schedule and each ad’s landing page, then launch.

The three settings to get right before you spend

The first is conversion tracking, because without it you cannot tell which keywords and ads bring in calls, forms or sales, and conversion-based Smart Bidding has nothing to optimize toward. You can measure conversions through the Google tag or through Google Analytics 4, whose key events can be imported into Google Ads. After you set up conversion tracking, place a real test enquiry and check the status of the conversion action. A new action may show “Awaiting conversions”, which means no conversions have been recorded in the last seven days; Google’s reasons include a new action, paused campaigns or low traffic, so this is not necessarily a fault. After testing, recheck the status and resolve any “Needs attention” or “Misconfigured” alert.

The second is location targeting, which matters most for a business serving one city, because Google’s recommended setting for Search, “Presence or interest”, can show your ads to people in your area and also to people elsewhere who have shown interest in it. That suits a hotel, but a Calgary-only plumber gains nothing from a click by someone in Toronto reading about Calgary. Google itself says “Presence” makes sense when you only want to reach people in specific locations, so To-The-TOP! recommends it for most local service businesses, targeting the real service area, whether a city, nearby communities or a radius. Because Google calls its location signals a best effort and not 100% accurate, check the location report after the first few weeks.

The third is a starting negative keyword list, built before launch rather than after the first bill. Add the obvious exclusions for your trade (jobs, training, free, DIY, and any competitor names you choose not to target), cover singular and plural forms, and add to it weekly from the search terms report. Alongside these three, check the ad schedule: for call-led campaigns, consider limiting call assets or ads to staffed hours, because a call that goes to voicemail at 9 p.m. costs the same as one that turns into a booking. Form, booking and ecommerce campaigns may justify broader schedules.

Does Google Ads work for a small business?

So how does Google Ads work for a Calgary plumber or any other one-city business? The mechanics are the same, but the result depends on a few prerequisites: a landing page that answers the search, a way to measure leads, a service area the business can actually cover, and enough budget to buy a meaningful number of clicks at its industry’s prices. Sending paid clicks to a home page with no clear next step, running Performance Max without conversion tracking, or targeting a whole province for a one-city business are easy ways to spend money without learning much. Before judging a new campaign, allow enough time to cover one or two conversion cycles and collect a meaningful number of clicks; the calendar time varies by business.

A simple break-even check for paid search helps before you start. Suppose, as an illustration, that an average job brings in $400 of gross profit, the landing page turns 1 in 20 clicks into an enquiry, and 1 in 3 enquiries becomes a booked job. Each booking then needs about 60 clicks, so the business breaks even at roughly $6.67 a click; where clicks regularly cost more, the landing page, the service advertised or the channel needs to change. Your own numbers will differ, which is why the sum is worth doing.

Google Ads and SEO are two different routes onto the same results page: ads are paid for click by click and appear in marked ad positions, while organic listings are earned by the page itself and cost nothing per click, although the SEO work behind them is not free. Paid search also stops the moment the budget stops, which is one reason to run it alongside organic work. Working with a Calgary SEO company can build rankings that keep bringing visitors, though that takes months rather than days and no ranking is permanent, while ads cover the gap and test which services and keywords bring enquiries.

For a second opinion on an existing account or a plan for a new one, To-The-TOP! offers Google Ads management from Calgary. Founded in 2007, it is run by one Google Ads certified practitioner who does the client work personally, so you can call (403) 308-5949 and talk it through with the person who would build the account. Whichever provider you consider, To-The-TOP! included, ask for the management fee and the ad spend as two separate numbers before you compare offers.
