What is a realistic ad budget to test Google Ads as a brand-new dropshipping store?

Thirty a day feels sensible. It is the number half of Reddit starts on. It is also the number that kills more new stores than a bad product does.

Google Ads needs conversions to learn who to show your products to. At 30 a day, a new store gets a handful of clicks and maybe a sale a week. That is not enough for the system to find a pattern, so the campaign sits in the learning phase, spends unevenly, and never settles. You spend 900 euros over a month and learn nothing, because there was never enough data to learn from. Spending less did not lower your risk. It just made the risk slower.

Plan on 50 euros a day for 30 days. About 1,500 euros. And plan it as one number you have already decided to lose, because a test you cannot afford to lose is not a test, it is a bet you will pull out of on day nine.

The 30 days matter as much as the 50. Two weeks tells you almost nothing: the first week is learning, and one good day can fool you into scaling something that was noise. Give it the full month before you judge it.

This decides the test before the ads do. Work out your gross margin per sale: what the item plus shipping costs you, taken off what you sell it for. If a product costs you 8 euros and sells for 20, that is 12 euros to play with.

Now ask honestly whether 12 euros can cover a cost per sale in your niche. In a lot of competitive ecom niches it cannot, and no amount of budget or clever targeting fixes it. If the margin is that thin, do not run the test. Change the product. ZenoX checks the margin room before we take on a store, because we would rather say no than spend a client's 1,500 euros proving arithmetic. Your margin is yours to know: we never ask for or handle client costs, we just tell you what the number has to clear.

You are not looking for profit in month one. You are looking for signal. A good test tells you which one or two products people actually buy, what a sale really costs you, and whether that cost is anywhere near your margin.

If one product comes out at a cost per sale under your margin, you have a business to scale. If everything is close but a bit over, that is a store and offer problem worth fixing. If nothing gets near it, the product was wrong, and 1,500 euros to learn that in 30 days is cheap.
