Key takeaways
- Google Ads has no set price. You pay per click set by an auction, within a daily budget you control.
- Cost per click varies by industry, location, competition, quality and device. Check your own account data, not generic averages.
- Size budgets backwards from target cost per lead, close rate and customer value.
- Management fees are separate. Ask whether they are a percentage, a flat fee or hourly, and what they cover.
01
How are Google Ads priced?
Search ads typically use cost per click. Advertisers set a budget and bids, and Google runs an auction each time a relevant search occurs. Ad rank reflects bid, expected impact of ad assets and formats, and the quality of the ad and landing page, so a better ad can win a position at a lower price than a weaker competitor.
The actual price per click is rarely the maximum bid. Because it depends on competing advertisers, it changes with season, hour and market, and no honest source can give you a fixed number before you run campaigns.
02
What drives cost per click?
Competition for the keyword is a major driver, alongside location, device, time of day, match type and relevance. Legal, finance and insurance are often described as expensive categories, but that is a common observation rather than a figure from Google, and your own account history beats any average.
Improving Quality Score components and conversion rate lowers your effective cost per lead even if cost per click stays the same.
- Industry and keyword competition
- Geography and audience
- Ad and landing page relevance
- Bid strategy and targets
- Seasonality and time of day
03
How do you set a budget?
Work backwards. Decide what a customer is worth and what you can pay to win one, then use your close rate to find the allowable cost per lead. Divide by expected cost per click to estimate clicks and conversion rate needed. Start with a test budget large enough to collect conversions, and raise it only when the numbers hold.
Illustrative example: if a job is worth 2,000 and you close one in four leads, a break-even cost per lead is 500 before margin, so a target well under that is the planning range. Replace these with your own figures.
| Input | Where to get it |
|---|---|
| Customer value and margin | Finance or CRM |
| Lead to customer rate | CRM stages |
| Allowable cost per lead | Value × margin × close rate |
| Cost per click | Keyword Planner estimates, then your account |
| Click to lead rate | Conversion tracking |
04
What do agencies charge?
Management is usually a percentage of spend, a flat monthly fee, hourly or a hybrid. A percentage model can reward higher spend rather than better results, so ask for reporting on cost per qualified lead. Insist that the ad account is in your name, and that you see spend and invoices directly from Google.
Be cautious of pricing that bundles ad spend with fees so you cannot see the split. Transparent reporting is part of the price you are paying for.
