I have audited hundreds of Google Ads accounts for local contractors. From Roofers in Miami to Plumbers in Seattle, the same patterns emerge.
It's rarely one big mistake that kills a campaign. It's usually a combination of these 20 Forensic Crimes. How many is your account committing right now?
I. The Keyword Crimes
Wasting money on the wrong people.
The "Dragnet" Error
#1
The Error: Using "Broad Match" keywords without restrictions.
The Consequence: A dentist pays for "dog toothpaste" clicks. An AC repairman pays for "auto AC repair" searches.
💡 Fix: Use Phrase Match ("") or Exact Match ([]).
The "DIY" Leech
#2
The Error: Forgetting to exclude negative keywords like "how to", "parts", "jobs".
The Consequence: You pay for people looking to fix it themselves, not hire you. High clicks, zero sales.
💡 Fix: Apply a "Universal Negative List" immediately.
Brand Cannibalization
#3
The Error: Bidding high on your own company name when no one else is.
The Consequence: Paying for traffic you would have gotten for free via SEO.
The "Single Ad Group" Mess
#4
The Error: Stuffing "Emergency Plumbing", "Water Heater", and "Drain Cleaning" into one Ad Group.
The Consequence: Irrelevant ads. Low Quality Score. You pay 2x more per click than you should.
Competitor Click-Bait
#5
The Error: Bidding on competitor names with misleading ad copy.
The Consequence: Users click thinking it's the other guy, realize it's you, and bounce immediately. Wasted spend.
II. The Space-Time Traps
Showing ads when and where you shouldn't.
The "Tourist" Tax
#6
The Error: Using Google's default "Presence or Interest" location setting.
The Consequence: A Miami roofer pays for clicks from people in New York just "looking" at Miami.
💡 Fix: Switch to "Presence: People in your location".
The "Ghost" Shift
#7
The Error: Running ads 24/7 when you only answer phones 9-5.
The Consequence: Paying for voicemails. Lead quality tanks after hours.
The "Radius" Overreach
#8
The Error: Targeting a 50-mile radius when you only drive 20 miles.
The Consequence: Paying for leads you have to reject because they are "too far."
Zip Code Blindness
#9
The Error: Ignoring income data. Advertising "High-End Remodeling" in low-income rental zip codes.
The Consequence: Getting calls from people who can't afford your service.
III. The Conversion Killers
Losing the customer after the click.
The "Home Page" Maze
#10
The Error: Sending ad traffic to your website's Home Page.
The Consequence: The user gets lost in your menu bar and leaves. Conversion rates drop by 50%+.
💡 Fix: Use dedicated Landing Pages.
Generic Ad Copy
#11
The Error: Ads that say "Best Service, Call Us."
The Consequence: You look like everyone else. Low CTR (Click Through Rate) = High CPC.
The "Form-Only" Wall
#12
The Error: Forcing emergency customers (like lockout victims) to fill out a contact form.
The Consequence: They don't fill it out. They hit "Back" and call your competitor.
The Stock Photo Fake
#13
The Error: Using perfect, smiling stock models instead of real photos of your team/trucks.
The Consequence: Zero trust. People think you are a lead-gen broker, not a local pro.
The Speed Trap
#14
The Error: Sending traffic to a slow WordPress site (5+ seconds load time).
The Consequence: 40% of mobile users leave before the page even loads. You paid for nothing.
IV. Technical Glitches
Broken data leads to broken decisions.
The Vanity Metric
#15
The Error: Counting "Page Views" or "Time on Site" as Conversions.
The Consequence: Google thinks it's doing a great job, but your phone isn't ringing.
The Auto-Apply Curse
#16
The Error: Letting Google automatically apply its "Recommendations."
The Consequence: Google adds broad keywords and increases budgets without your permission.
💡 Fix: Turn OFF Auto-Apply immediately.
Double Counting Illusion
#17
The Error: Importing conversions from Analytics AND using Google Ads tags for the same event.
The Consequence: One lead counts as two. Your CPA looks artificially low.
The "Smart Campaign" Trap
#18
The Error: Using Google's simplified "Smart Mode" instead of Expert Mode.
The Consequence: Zero control over negative keywords or bidding. A "Black Box" for your money.
V. The Money Leaks
Bidding and budget errors.
The "Max Clicks" Burn
#19
The Error: Using "Maximize Clicks" bidding without a CPC Limit.
The Consequence: Google will pay $50 for a $10 click just to spend your daily budget faster.
Budget Exhaustion
#20
The Error: Running out of budget by 10 AM because of poor pacing.
The Consequence: You miss all the prime-time customers in the afternoon and evening.
