How Much Does Google Ads Cost an Online Store?

You pay Google Ads for clicks on your product ads and cap the total with a daily budget. There is no fixed price, flat fee or subscription. In our study of 1.4 million products across 130+ stores, a click cost $0.20 on average, and the minimum test of one product took 15–20 clicks, about $3–4. The monthly amount is up to you. In GetProfit data on 95 stores, the ones that doubled their ad revenue within a year started from a median $313 a month.

Our Google Ads budget guide covers the wider questions: how much to spend in total, how to split it between campaigns and how to pace it through the month.

What exactly do you pay Google for?

Google’s own article (How much does Google Ads cost?) says that how much you invest is up to you, with no flat fee or monthly subscription. How you pay depends on the campaign type:

Google notes that these are the most common combinations and that many campaign types support more than one pricing model. For free listings, Google’s Merchant Center page says that a Merchant Center account and showing your products on Google are free. Paid product ads show your products more prominently.

Performance Max, Google’s automated campaign type, works differently. It supports only two bid strategies, Maximize conversions and Maximize conversion value, each with an optional target (Google Ads API, Create a Performance Max campaign). So instead of a bid per click, you set a budget and, if you want, a target, and the bidding sets the cost per click.

For most stores, Performance Max is most of the bill: it runs in 141 of 146 stores in our data and takes a median 95.7% of their ad budget (GetProfit data, June 2025 – June 2026).

Your budget caps the total. Every campaign needs either an average daily budget or a campaign total budget for a set period. On a busy day, a campaign can spend up to twice its daily budget. Over a month, though, you pay at most the daily budget × 30.4, the average number of days in a month (Google Ads API, Campaign budgets overview).

What does one click cost an online store?

In our study of 1.4 million products, a click cost $0.20 on average across 130+ stores, with five currencies converted to dollars. The stores are in Czechia, Poland, other EU countries and Ukraine. Use $0.20 as a reference point for product ads in these markets. Your category, country and competitors set your own cost per click.

Cost-per-click averages for search ads across all industries describe a different market. Google itself notes that industries with high-value customers, such as legal services or real estate, often see higher bids. A store’s product ads and a law firm’s search ads compete against different advertisers.

What sets your cost per click

Google prices every click in a real-time auction. According to Google’s article on Google Ads costs, each ad gets an Ad Rank, which decides whether the ad appears, in what position and how much you pay. Ad quality and relevance count as much as the bid. Competition, seasonal trends and targeting choices such as location or audience also move the final cost.

Under Performance Max or Smart Bidding (Google’s automated bid strategies), the cost per click is an outcome: you influence it through the target and the budget. Outside Performance Max, a target ROAS (return on ad spend) portfolio bid strategy, which several campaigns share, can also set maximum and minimum bid limits (TargetRoas, Google Ads API).

What you can afford per click

Compare your cost per click with the most you can pay for a click before an order stops paying for itself. That ceiling is your break-even CPC: gross profit per order × conversion rate.

Example store, not client data.

A tableware shop pays 5 per click: 40,000 of spend for 8,000 clicks. Its average order value is 600 and its gross margin is 35%, so each order leaves 210 of gross profit. With a 3.75% conversion rate, one click is worth 210 × 3.75% ≈ 7.9 of gross profit.

At 5 per click, each click brings in more gross profit than it costs. At 8 per click, the shop would lose money on every order.

How much does it cost to test one product?

A product ad tells you something once it has had enough clicks. In our study of 1.4 million products, the minimum test of a product was 15–20 clicks, about $3–4 at the study’s average $0.20 per click. With fewer clicks, you are judging noise. The threshold depends on the category:

Per product, these sums look small. Across a whole catalogue, they add up. More than half of the products in the study went untested: 55.0% received no ad budget over 13 months.

Example store, not client data.

A tableware shop with 3,000 products pays 5 per click and spends 40,000 a month. Only 1,200 of its products got at least one impression last month. Tableware sits in home and garden, where the minimum test is 20 clicks.

Testing one of the 1,800 products with no impressions costs 20 × 5 = 100, and testing all of them costs 1,800 × 100 = 180,000. That is 4.5 months of the shop’s current spend, so the shop has to test its catalogue in batches its budget can carry.

The GetProfit portal sets the upper limit for a test. Its campaign-structure rules mark a product for exclusion once it has had 50 or more clicks and no conversion in 360 days. At the tableware shop’s 5 per click, that is 250 per product before the rule applies.

Clicks get dearer when you scale, and ROAS holds

We looked at 1,360 store-months in GetProfit data (June 2025 – June 2026). A store-month is one store’s results for one month.

Each month, we compared every store’s change in spend, cost per click and ROAS with the median change of all stores that month. That removes the season and anything else that hit everyone at once. The table shows median changes, each measured against other stores in the same month:

The cost per click follows spend in both directions. Stores that raised spend by more than 70% in a month paid a median 9.2% more per click than other stores that month. Stores that cut it by more than 30% paid 10.4% less. Higher spend goes together with dearer clicks.

ROAS barely moved. Across all 1,360 store-months, the rank correlation between changes in spend and changes in ROAS was +0.026, which means practically no link.

Two caveats apply. These are observations, not an experiment: a store may raise its budget because sales are already growing. Also, our ROAS counts revenue, not profit, because our data has no product costs.

So when you plan a much larger budget, assume a somewhat higher cost per click than today’s. Then check that this cost per click stays below your break-even CPC (gross profit per order × conversion rate).

How much do online stores really spend a month?

Google leaves the monthly amount up to you. Its free Google Advertising Cost Tool shows the daily range that half of advertisers in your industry and location spend. Our data shows where real stores started and where they ended up a year later.

We took 95 stores in GetProfit data and compared each store’s first three months (June–August 2025) with its last three (April–June 2026). We converted amounts to dollars at fixed rates.

The other 16 stores grew between 1.2× and 2×. Of the three groups, the stores that doubled started from the smallest spend. A small base is also easier to double, so read this as an observation, not a rule.

Each of the 23 stores that doubled raised spend or ROAS by more than 20%: 15 raised spend, 18 raised ROAS, and some did both. If your budget is in the hundreds of dollars a month, see how to make Google Ads work on a small budget.

Your own monthly cost in one line

Monthly spend = the orders you want × cost per order, where cost per order = cost per click ÷ conversion rate.

Example store, not client data.

A tableware shop pays 5 per click and converts 3.75% of clicks, so one order costs 5 ÷ 3.75% ≈ 133. For 300 orders a month, it needs 300 × 133 ≈ 40,000. Its average daily budget is 40,000 ÷ 30.4 ≈ 1,316, and on a busy day spend can reach up to about 2,632.

A portal rule adds a floor: each campaign needs a daily budget of at least 3× the target cost per order. With a target of 133, that is 399 a day for each campaign.

For the full method, from order value and margin to a monthly figure, use the budget calculator.

This formula covers Google’s charges only. If an agency or freelancer runs the account, their fee comes on top. We cover the fee models in what Google Ads management costs.

How to work out what Google Ads will cost your store

1. Find your actual cost per click. Look at the average cost per click by campaign for the last 90 days. Under Performance Max, the bidding sets it, so you only read it.
2. Compare it with your break-even CPC. That is gross profit per order × conversion rate. If you already pay more than that, a bigger budget deepens the loss.
3. Set a test budget per product. Take the minimum number of clicks for your category from our study: from 15 for bags and luggage to 50 for hobbies and crafts. Multiply it by your own cost per click, not by $0.20.
4. Count the products with no impressions. Multiply their number by the test budget per product. That is the price of learning what they are worth, so test them in batches.
5. Build the monthly budget from orders. Multiply the orders you want by your cost per click and divide by your conversion rate. Divide the result by 30.4 for the daily budget. Spend on a single day can reach up to twice that.
6. Raise the budget in steps. The portal recommends changing a budget by at most 20% at a time. When you raise spend sharply, plan for a higher cost per click.

Our sample gives reference points; your own account sets the real price. The account score in the GetProfit portal turns what it finds into money: how much spend misses the goal, counted on your store’s own history rather than on market averages.

What state your ad account is in. One score instead of a dozen tabs of figures — plus a breakdown of exactly where the money leaks. The portal changes nothing without your consent.
