How much does Google Ads cost?
Short answer: Google Ads cost is not set by a price list. You choose an average daily budget and usually pay per click, and the price of each click is decided in an auction every time someone searches. The same budget can therefore buy many clicks in one industry and few in another. The safest way to set a budget is to work backwards from what a new lead or customer is allowed to cost. On top of the clicks, most businesses also pay an agency or consultant and invest in landing pages and tracking.
How does Google Ads pricing work?
Google Ads pricing is auction based. Every time someone makes a search your ad could appear on, Google runs an auction among the eligible advertisers. In a standard Search campaign you pay when someone clicks, so the central number is the cost per click, or CPC.
In each auction Google calculates an Ad Rank for every ad, and that score decides whether the ad shows and in which position. What you are finally charged is called the actual CPC. Google describes it as the amount minimally required to clear the Ad Rank thresholds and beat the Ad Rank of the competitor immediately below you (Google Ads Help). That is why you are often charged less than your maximum bid. With automated bidding, individual clicks can cost more than your maximum CPC.
This is why nobody can say in general how much it costs to advertise on Google. A price always belongs to one keyword, in one region, at one moment, against the advertisers in that auction.
What affects your cost per click?
Your cost per click is driven by the six factors Google uses to calculate Ad Rank (Google Ads Help). You control your bid and your quality directly. To competition and context you can only respond, for example with more specific keywords or tighter location settings.
| Factor | What it means |
|---|---|
| Your bid | The most you are willing to pay for a click |
| Quality of ad and landing page | How relevant and useful your ad and page are for the search |
| Ad Rank thresholds | A minimum level an ad must reach to show at all |
| Competitiveness of the auction | How close the other advertisers are to your Ad Rank |
| Context of the search | The search terms, location, device and time of the search |
| Expected impact of assets and formats | Extra elements such as sitelinks and call assets |
Google states that higher quality ads can often lead to lower CPCs (Google Ads Help). In the account you see this as Quality Score, a figure from 1 to 10 per keyword built on three components: expected clickthrough rate, ad relevance and landing page experience. Each is rated above average, average or below average. Google is explicit that Quality Score is a diagnostic tool and is not an input in the ad auction (Google Ads Help). Use it to see what needs fixing.
We do not quote average CPC figures, because one average says little about your keywords. For an estimate that fits your business, use Keyword Planner in Google Ads. It shows the average cost for your ad to show on searches for a keyword, and its forecast estimates how many clicks, impressions or conversions you are likely to get for your spend (Google Ads Help). You need a Google Ads account with billing information entered. Treat the figures as estimates and replace them with your own data after the first weeks.
How much budget do you need per month?
You need enough budget to buy the number of leads or sales you are aiming for at a cost per conversion you can afford, plus enough conversions to judge whether the campaign works. Your Google Ads cost per month is set by the average daily budget you give each campaign.
Two rules from Google matter here:
- Daily spend can vary. On a given day a campaign might spend up to twice its average daily budget when traffic is higher than usual. Over a month you will not spend more than 30.4 times your average daily budget (Google Ads Help).
- Automated bidding needs data. For Target CPA, Google recommends measuring performance over the last 30 days, including at least 30 conversions (Google Ads Help). A budget that produces five conversions a month takes a long time to tell you anything reliable.
What does a Google Ads agency charge?
A Google Ads agency charges for its work separately from the ad spend, which goes directly to Google. There are four common fee models.
| Fee model | How it works | Suits you when | Watch out for |
|---|---|---|---|
| Fixed monthly fee | An agreed amount each month for an agreed scope of work | You want a cost that is easy to compare with results | A scope that is not written down |
| Percentage of ad spend | The fee is a share of what you spend with Google | Spend and workload really do rise together | The fee grows with the budget, which gives the agency a reason to recommend more spend |
| Hourly rate | You pay for time used | You need an audit, training or occasional help | Open-ended invoices with no agreed outcome |
| Setup fee plus retainer | A one-off fee for the build, then a monthly fee | Account, tracking or landing pages must be built from scratch | Who owns the account and the tracking if you leave |
We do not state typical fee levels. They depend on the scope of work, and Google Ads pricing from one agency website is not a market price. Compare quotes by what is included: keyword work, new ads, landing pages, conversion tracking and reporting can sit inside or outside the fee.
CaptivateClick charges a fixed monthly fee, not a percentage of ad spend, and proposes a starting budget and fee after a first conversation. Read more about how we work as a Google Ads agency.
How do you calculate a budget from your target CPA?
Start from what a sale is worth and work backwards to a monthly budget, a daily budget and the highest click price you can afford. You need four numbers: gross profit per new customer, the share of leads that become customers, your landing page conversion rate and the number of leads you want per month.
- Break-even CPA = gross profit per customer × share of leads that become customers
- Highest average CPC = target CPA × conversion rate
- Monthly budget = target CPA × number of leads you want
- Daily budget = monthly budget ÷ 30.4
Worked example with made-up numbers
The example uses round, made-up numbers to show the method. They are not typical click prices for any industry. It is written in pounds, and the maths is identical in dollars.
| Step | Example |
|---|---|
| Gross profit per new customer | £1,000 |
| Share of leads that become customers | 20% |
| Break-even CPA per lead | £1,000 × 0.20 = £200 |
| Target CPA, so that profit is left | £100 |
| Landing page conversion rate | 5% |
| Highest average CPC | £100 × 0.05 = £5 |
| Leads wanted per month | 20 |
| Monthly budget | 20 × £100 = £2,000 |
| Daily budget | £2,000 ÷ 30.4 ≈ £66 |
Then compare with reality. If Keyword Planner suggests your most important keywords usually cost more than £5 a click, the sums do not work at a 5 percent conversion rate. You then have three levers: raise the conversion rate, raise the value of each customer or choose keywords with clearer buying intent.
To assess a Target CPA strategy the way Google recommends, with at least 30 conversions in 30 days, the budget in the example would need to be around 30 × £100 = £3,000 a month.
The target CPA only covers ad spend. To see what a customer costs once the agency fee, tools and sales time are included, read Customer acquisition cost. If you sell products with different order values, a revenue target is often a better steer than a cost target, which we cover in What is a good ROAS?
How can you lower your Google Ads cost?
You lower your Google Ads cost per lead by removing clicks that never convert and getting more leads from the clicks you keep. Cutting bids alone usually just buys fewer clicks.
- Get conversion tracking right first. Without correct conversions you cannot calculate a CPA, and automated bidding optimises towards the wrong thing.
- Add negative keywords. Review the search terms report regularly and exclude searches that never lead to a sale, such as people looking for jobs or free alternatives.
- Send each click to a page that answers the search. A specific landing page usually converts better than the home page, and landing page experience is one of the three Quality Score components. Doubling the conversion rate in the example above from 5 to 10 percent doubles the click price you can afford, from £5 to £10. See What is a good conversion rate?
- Tighten the context. Limit the campaign to the area you serve and review results by device and time of day.
- Use fewer campaigns. A small budget split across many campaigns gives each one too little data.
- Steer by cost per lead or sale, and give changes time. Cheap clicks that do not convert are expensive. Follow CPA against your break-even, avoid changing targets every week, and check after each change that the number and quality of leads hold.
