What are the biggest mistakes beginners make with Google Ads?

Trusting Google's "Default" Campaign Settings​


When you create a new Search campaign, Google quietly automatically checks two boxes that can completely destroy your ROI:


  • The Display Network Expansion: Google will take your search text ads and show them as banners on random apps and websites. This traffic is notoriously low-intent and usually results in accidental mobile clicks that drain your daily budget.
  • The "Presence or Interest" Location Trap: By default, Google targets people "in, or who show interest in" your location. If you are a local plumber in Chicago, someone in London searching for "Chicago plumbing history" could trigger your ad.




The Fix: Always uncheck the Display Network when running Search campaigns. Under Location options, change target settings from Presence or Interest to "Presence: People in or regularly in your targeted locations."
 
i think the bigest mistake is trusting google automated recomndations blindly and not split testing there landing pages properly.
 
One big beginner mistake is google ads is copying strategies from youtube or twitter without real data. PPC is very specific, so what works for others often fails if your audience or offer is diffrent.
 
One of the biggest beginner mistakes in PPC is changing too many things at once on Google Ads. when they tweak keywords, ads, bidding, and landing pages together, they never know what actually caused performance changes.
 
Beginners often use broad match keywords, letting Google show their ads for completely irrelevant searches. Stick to phrase or exact match early on to protect your budget from burning fast.
 
most beginners waste budget by testing too many things at once and not giving enough data to a single campaign, plus weak tracking setup and wrong keyword intent targeting.
