Running Google Ads sounds simple at first. You create a campaign, add some keywords, set a budget… and expect results.

But many people end up spending money without really understanding where it went wrong. Not because Google Ads doesn’t work — mostly because of small mistakes that quietly drain your budget.

Here are some common ones I’ve noticed.

1. Targeting Too Broad Keywords

This is probably the most common mistake.

People choose very general keywords like “shoes” or “digital marketing,” thinking it will bring more traffic. Yes, it brings traffic… but not always the right audience.

Broad keywords = more clicks + less conversion + wasted budget.

Sometimes being specific works better than being visible everywhere.

2. Sending Traffic to the Wrong Page

Running a good ad but linking it to a weak or unrelated landing page is a silent budget killer.

If your ad promises one thing and the page shows something else, users leave quickly. Google notices this too, and your quality score can drop.

Ad and landing page must feel connected. Otherwise, clicks don’t mean much.

3. Not Tracking Conversions Properly

Some people only track clicks and impressions, but ignore conversions.

Clicks don’t always equal results.

Without conversion tracking, you won’t know:

Which keyword works

Which ad is wasting money

Where leads actually come from

And then optimization becomes guesswork.

4. Setting and Forgetting the Campaign

Google Ads is not something you set once and relax.

Performance changes. Competitors change. Cost changes.

If you don’t check regularly:

Budget may drain faster

Irrelevant keywords may grow

Weak ads may continue running

Even small weekly adjustments can make a big difference.

5. Expecting Instant Perfect Results

This one is more psychological than technical.

Many people expect immediate ROI. When it doesn’t happen, they stop too early or make random changes.

Google Ads usually needs testing:

Testing keywords

Testing ad copies

Testing audience

Sometimes the first campaign teaches more than it earns.
