Google Ads' total cost combines media spend paid to Google, campaign management and any initial setup work. There is no universal click price or monthly budget. A useful estimate connects your business goal and search demand with how many visitors could become suitable leads or customers.
Separate media spend, specialist work and setup costs
Media spend funds ad delivery in Google Ads. Specialist work can include campaign planning, search term reviews, optimisation and reporting. Initial work can also include tracking setup, landing page development or ecommerce product feed fixes.
Ask for these costs to be itemised. Check whether amounts include VAT, what is charged initially and what continues monthly. Media spend and an agency's service fee are separate costs.
| Cost | What it covers | What to ask |
|---|---|---|
| Media budget | Ad delivery in Google Ads | What is the agreed budget and who pays Google? |
| Ongoing work | Monitoring, development and reporting | What gets done, how often and by whom? |
| Setup | Building the account, measurement and campaigns | What one-off costs arise before launch? |
| Pages, creative and tools | Supporting implementation | What is included and what is ordered separately? |
Why does the click price vary?
Alongside the bid, Google's auction considers factors such as ad and landing page quality, competition, search context and the expected benefit of ad assets. The highest bid does not alone determine visibility, and industry alone does not establish an individual click price.
Estimate a starting point from account history or forecasts for your search themes, then verify it against actual data. A cheap click matters only if it brings a suitable customer. A more expensive service query can be justified where customer value and the probability of a sale are higher.
Calculate what could happen within a budget
In a hypothetical example, a €600 monthly media budget with an actual average click price of €3 provides around 200 clicks. If 5 per cent generate a quote request, there are 10 requests at a media cost of €60 each.
If campaign work costs another €300 that month, the combined cost is €900 and the cost per request is €90 before other expenses. If two requests become customers, acquisition cost is €450 per customer. These are assumptions for a calculation, not Digitari's price list or a promise of results.
| Measure | Example calculation | Result |
|---|---|---|
| Clicks | €600 / €3 | 200 |
| Quote requests | 200 × 5% | 10 |
| Media cost per lead | €600 / 10 | €60 |
| Cost per lead including work | €900 / 10 | €90 |
| Cost per customer including work | €900 / 2 | €450 |
Calculate a lead cost ceiling from customer margin
In a lead-generating business, an acceptable cost also depends on the share of enquiries that become sales. If a customer generates €800 in contribution margin before acquisition and one in four leads becomes a customer, expected margin per lead is €800 × 25 per cent, or €200.
That €200 is this example's theoretical ceiling: it would spend all expected margin on acquisition. Set the practical target lower to leave a return and room for uncertainty. Use realised sales rates and margin rather than just lead volume or customer revenue.
For ecommerce, ROAS alone does not establish profitability
ROAS compares sales attributed to advertising with media spend. Sales of €3,000 against €600 media spend give a ROAS of 5. That does not establish profit because product costs, returns and campaign work also affect the outcome.
If the example assumes a 30 per cent contribution margin after all variable order costs, €3,000 in sales leaves €900. Deduct €600 for media and €300 for campaign work and nothing remains before other business expenses. An apparently strong ROAS can therefore be too low for the business.
A daily budget is an average, not always a daily cap
Google states that most campaigns using average daily budgets have a daily billing limit of twice that budget and a monthly limit of 30.4 times it. An unchanged €20 daily budget therefore generally has a €608 monthly limit.
Changing budgets during the month or using another budget type affects the calculation. Review spend and forecasts in the budget report, and include all campaigns in your overall plan. A new campaign should share the agreed media allocation rather than silently increasing it.
What should you ask about a Google Ads proposal?
A useful proposal describes the work and how its results will be assessed. A calculation helps the discussion, but your budget should reflect demand, goals, website readiness and sales capacity.
- What is the media budget and the separate service fee?
- What is included in setup, ongoing optimisation and reporting?
- Which conversion is the goal, and how is its quality checked?
- Does the business own the account and have direct access to its data?
- How are sales, margin and labour costs reflected in the review?
- When will the test be assessed, and what justifies a budget change?
Start with measurement and a focused test
Once your priority service, its margin and a suitable customer are defined, you can size a test budget with a clear rationale. Check tracking and the landing page before launch. Then change one substantial factor at a time so you can understand what affected the observations.
