How Long Until Real Data?
Google Ads needs roughly 20–30 conversions before the numbers mean anything. Find out how many weeks — and how much spend — that takes at your budget.
How to use
Enter budget and CPC
Your monthly budget and roughly what a click costs you. If you do not know the CPC, leave the default — it is a common ballpark.
Set a conversion rate
What share of clicks turn into an enquiry or sale. Typical small-business sites land between 3% and 7%.
See the honest timeline
How many weeks and how much spend before you have enough conversions for the numbers to mean anything.
Why 20–30 conversions? Below roughly that number, the difference between two weeks of results is mostly luck. Optimising on a handful of conversions means reacting to noise — which is how budgets get churned. This is the single most useful expectation to set before you start.

Frequently asked questions
Why 20–30 conversions?
Below roughly that number, the gap between a good week and a bad week is mostly luck. Optimising on a handful of conversions means reacting to noise — which is one of the most common ways small budgets get wasted.
So Google Ads does not work on a small budget?
It does — it just takes longer to know whether it is working. That is arithmetic, not failure. On a smaller budget the fix is to narrow the targeting so every euro goes to your very best searches, and to judge results over months rather than weeks.
Is the conversion rate default realistic?
The 3–7% band covers most small-business sites. Your real figure depends heavily on your landing page and how closely your ads match what people searched for, so use your own number if you have one.
What if I judge the results sooner?
You will very likely make the wrong call — pausing something that was working, or scaling something that was not. Knowing the honest timeline before you start is the single best protection against that.
