A guide that shows you what's really happening in your ad account

You spend money on Google Ads, customers aren't coming in, and you don't know if it's a matter of industry, season, or someone simply set something up incorrectly and nobody checked. The truth is, most small business accounts are riddled with the same errors. Simple oversights that cost dozens of zlotys a day—and nobody catches them because nobody looks deeper.

We've listed 10 such errors. Specifically, what's wrong, how much it could cost you, and how to check it yourself in 10 minutes.

You don't have to be an expert to understand this

It doesn't matter whether you click in the panel yourself or you've hired someone to do it and want to make sure they're doing it right - this guide is here to help you judge for yourself.

You won't find generalities like "optimize your campaign" or "work on your targeting." Instead, you'll find specific areas in the dashboard where you should click, concrete numbers showing how much each omission could cost you, and clear guidance on what to change to stop paying for clicks that don't sell anything.

Each chapter will give you something you can immediately test in your own account—no waiting around, no scheduling a consultation, no additional tools required. All you need is access to the Google Ads dashboard and those 10 minutes we mentioned earlier.

  4. The entire offer in one campaign – and how to organize it to make money on what is actually profitable
  5. Ads that lose the auction because they are simply unfinished
  6. The only bug on the list that doesn't cost anything to fix

  8. The cheapest conversions you could have – and no one started collecting them
