Common Google Ads mistakes

This lesson covers

  • The most expensive beginner mistakes
  • How to spot each one in your account
  • The quick fix for each

Short answer

The biggest beginner mistakes are running Search campaigns with the Display Network turned on, using broad match without data, and launching with no conversion tracking. Others include the wrong location option, no negative keywords, and sending ads to the homepage. Most take minutes to fix and save real budget.

The Display Network trap

When you create a Search campaign, Google may tick Include Google Display Network by default. Your text ads then also show as banners on websites and apps.

Those clicks are often cheap but low intent. For a beginner Search campaign, untick it. You can also untick Search partners at first, so you only appear on Google Search.

Small mistakes that add up

Ads running when no one can answer calls, spelling errors and vague ad copy, changing the bid strategy every week, clicking your own ads, and judging results after only a few days.

Try it: spot the mistake
