If you’ve ever launched a Google Ads campaign and found yourself staring at the budget going up… faster than the leads coming in? You’re not alone.
Most small business owners sooner or later end up asking the same thing:
“Why are my Google Ads so expensive?”
Let’s break that down. Not in a vague, fluffy way, but in a way that actually makes sense with real causes, real fixes, and a few “ah, that explains it” moments.
1. Google Ads Works on a Real-Time Auction System
Google Ads isn’t like placing a classified ad in the newspaper. There’s no flat fee.
Instead, every single time someone searches something, say, “emergency plumber near me,” Google runs a real time auction. Advertisers bid on that keyword at that very moment.
And here’s the catch:
The more advertisers bidding on that keyword?
The higher the cost per click (CPC) climbs.
More demand = higher price. Simple supply and demand.
You can learn the mechanics of this directly from Google’s explanation of its auction system.
2. Some Industries Are Just… More Expensive
Let’s be honest, not all clicks are created equal.
Some industries have incredibly high customer value. That means businesses are more than willing to pay $50… $80… even $100+ per click because just one customer could be worth thousands.
A few high CPC industries:
Legal (especially injury lawyers): $30-$100+
Insurance: $20-$70
Dentists: $10-$50
HVAC / Roofing: $10-$40
Meanwhile, smaller local services like fitness coaching, pet grooming, or house cleaning? Usually around $2-$10 per click.
So yeah, if you’re in a high stakes industry, you’re going to feel the heat more than others.
(If you’re curious, the 2024 Google Ads Benchmarks from WordStream offer a great CPC overview by niche.)
3. Poor Campaign Setup = Bleeding Money
Even if your industry isn’t expensive… poor setup can make it that way fast.
I’ve seen small businesses burn hundreds (even thousands) simply because of:
- Using broad match keywords with no filters
- Running search and display ads together in the same campaign
- Not setting negative keywords to block irrelevant traffic
- Forgetting to target the right locations
It’s a little like leaving the tap running. You don’t always notice the leak until the water bill shows up.

4. A Low Quality Score = Higher Costs
This one stings a bit because it’s less visible.
Google gives each of your keywords a Quality Score based on how relevant your ad and landing page are.
If your ad doesn’t match the keyword, or your landing page doesn’t deliver a good experience, your score drops.
And when that happens? Google makes you pay more to show your ad.
The factors behind Quality Score include:
- Relevance between keyword and ad
- Expected click-through rate (CTR)
- Landing page quality
You can read more directly from Google’s guide on Quality Score.
A small tweak in your ad text… or even cleaning up your landing page… can reduce costs more than you think.
5. Wrong Bidding Strategy
Sometimes, it’s not what you’re doing it’s how you’re bidding.
If you start with “Maximize Clicks” and don’t set any limits, Google will happily spend as much as you allow.
Here are a few things that usually go wrong:
- Choosing an aggressive bidding strategy too early
- Bidding on broad, generic keywords
- Not adjusting bids based on device, location, or time of day
When you’re just getting started, go slow.
Use Manual CPC or Enhanced CPC.
As data comes in, shift into smarter bidding.
6. Costs Can Rise Over Time Even If You’re Doing It Right
Here’s something people don’t talk about enough.
Even if your setup is clean and your ads are converting…
Your CPC can still go up over time.
Why?
- More competitors enter your market
- Your ads get stale (CTR drops, Quality Score goes down)
- Seasonality or market behavior changes
It’s not sabotage. It’s just how the platform works.
You can’t set and forget. You have to keep optimizing consistently.
