# How long do ads need before you can tell whether they work?

First week: four enquiries on Monday, none on Tuesday, two on Wednesday. The budget is limited and every week is felt.

We are in the first week of running ads. Monday brought four enquiries, Tuesday none, Wednesday two.

Our supplier asks us not to touch anything and to give it time. It feels to me as if we are pouring money in and ought to change something right now. Our budget is limited, so every week is noticeable.

How long do you wait before conclusions mean anything?

What you have to count is the number of events a conclusion can rest on. Days tell you almost nothing here.

The platform spends the first days learning and distributes delivery unevenly. Assessing the result during that period achieves nothing; the numbers jump for reasons unconnected to your settings. As an order of magnitude: until a few dozen clicks per ad and at least a handful of enquiries have accumulated, the difference between variants is noise. On a modest daily budget that takes weeks, and that is normal.

Switching off earlier is worth it only on crude signals, such as hundreds of impressions producing no clicks at all, or a cost per click several times what you expected. Those point to an obvious mistake in the setup or the copy.

A useful habit at the start: write down before launch what result you would consider normal. Without that, the discussion a month later comes down to impressions, and the same result can be presented as a success or a failure.

What budget makes a start worthwhile at all is covered in the [article on Google Ads budgets](https://illia-biztech.de/en/blog/google-ads-budget-kleines-unternehmen).
