Every successful campaign needs strong negative keywords, good quality scores, and proper match types. You should optimize your landing page speed, set up proper bid adjustments, and write compelling ad copy. These are the fundamentals, and they are crucial. But you already know that.
What you might not know are the hidden issues that plague even technically perfect campaigns. The sneaky problems that persist after you’ve mastered the basics and still leave you wondering why your conversion rates aren’t higher.
This article digs into those hidden conversion killers, exposing three critical areas:
- Campaign settings that waste your budget despite perfect keyword strategies
- Website issues that drive away traffic even with lightning-fast load times
- Tracking problems that mislead you even when your analytics setup seems solid
Each section comes with practical fixes you can implement today. No theory, no repetitive basics – just solutions to the problems most PPC managers don’t know to look for until it’s too late.
1. Campaign settings that kill conversions
#1 Fighting for first position
Being first sounds great, but with paid search, it’s often a costly mistake. First position gets more clicks but fewer conversions, especially with smaller budgets.
How to fix it:
- Use position 1 only for brand terms
- Target positions 2-4 for commercial keywords
- Save budget for high-intent searches
- Set CPCs at 70% of what position 1 typically costs
#2 Location targeting that backfires
Using dynamic location insertion ({Location}) seems smart, but often creates a poor user experience. When parameters pull wrong city names, users get confused and bounce.
How do you fix it?
- Create dedicated campaigns:
- One campaign per main city
- Write city name directly in ad copy
- Use matching landing pages
- Set proper targeting:
- Target “People in” each location
- Add relevant radius (10-15 miles)
- Exclude areas you don’t serve
#3 Shopping campaign priority mess
Multiple shopping campaigns set to the same priority level will inevitably fight each other for the same products. This raises costs and messes up which products show for what searches.
How do you fix it?
- Set clear priorities:
- High: Best sellers and seasonal items
- Medium: Regular products
- Low: Clearance and low margin items
- Add negative keywords between campaigns
#4 Mixed up conversion actions
Wrong conversion actions in your sets make campaigns optimize for the wrong goals. Like optimizing for newsletter signups instead of sales.
How do you fix it?
- Check conversion settings:
- Review all your active conversion actions
- Remove low-value actions from sets
- Set correct values for each action
- Create separate sets for:
- Primary goals (sales, leads)
- Secondary goals (downloads, signups)
#5 IP exclusions missing
Your own team’s clicks waste budget and mess up your data. This includes office staff, remote workers, and agencies checking ads.
How do you fix it?
- Gather all IPs:
- Office locations
- Remote worker IPs
- Agency IPs
- Add them to exclusions at account level
#6 Ad extensions showing at wrong times
Call extensions active at 3 AM or location extensions showing on holidays waste clicks when you can’t convert them.
How do you fix it?
- Match business hours:
- Set schedules for call extensions
- Align location extensions to open hours
- Add holiday schedules to extensions
#7 Hidden retargeting waste
Most retargeting includes everyone – even 2-second bounces. This wastes budget on people who never showed real interest.
How do you fix it?
- Set smarter audiences:
- Include: Cart abandons, 2+ page views
- Exclude: Bounces, single-page visits
- Create engagement tiers:
- High intent (pricing, cart)
- Medium intent (product pages)
- Low intent (blog, homepage)
#8 Underperforming locations
Poor performing cities often hide in your overall stats, dragging down campaign performance without you noticing.
How to fix it:
- Check location reports:
- Find cities with high cost/low conversions
- Compare CPAs across regions
- Take action:
- Exclude worst-performing cities
- Reduce bids in weak areas
- Increase budgets in strong areas
2. Website issues that kill conversions
#9 Popup overload
Imagine walking into a store and being stopped three times before seeing any products. That’s what we do online with cookie notices, chat widgets, and discount popups. For new visitors (60-85% of traffic), it’s a terrible first impression.
How do you fix it?
Audit your popups:
- List all automatic popups
- Time how long before each appears
- Test as a new visitor (clear cookies)
- Set better rules:
- No popups for first 30 seconds
- Max one popup per visit
- Save chat widgets for return visitors
#10 Missing social proof
When your landing page lacks reviews or testimonials, visitors have no reason to trust you over competitors.
How to fix it?
- Add proof elements:
- Customer reviews near buy buttons
- Industry awards or certifications
- Clear return/refund policies
- Keep it real:
- Use full names when possible
- Include customer photos
- Update reviews regularly
#11 Poor product presentation
Bad product photos and vague descriptions kill trust. If they can’t see what they’re buying clearly, they won’t buy it.
How to fix it?
- Improve images:
- Clear, high-res photos
- Multiple angles
- Size reference shots
- Write better descriptions:
- Specific measurements
- Material details
- Clear use cases
#12 Limited payment options
Missing popular payment methods means losing easy sales. Different customers expect different options.
How do you fix it?
- Cover the basics:
- Major credit cards
- PayPal
- Shop Pay or Apple Pay
- Show payment icons:
- Display options clearly
- Add “secure checkout” badges
- Show currency options
#13 Form fields gone wrong
Forms are often the final step before conversion, but messy forms kill completion rates. Too many fields, unclear requirements, and broken autofill are common culprits.
How do you fix it?
- Simplify fields:
- Remove unnecessary fields
- Mark required fields clearly (*)
- Enable browser autofill
- Make it smooth:
- Show errors instantly
- Keep all fields visible (no hidden ones)
- Add progress steps for long forms
#14 Mobile experience blocks
Your site might look great on desktop, but mobile users often can’t click buttons, see forms, or read text properly.
How do you fix it?
- Check common issues:
- Test all buttons on mobile
- Ensure forms fit screen width
- Check text size and spacing
- Fix navigation:
- Make menu items finger-sized
- Keep CTAs visible without scrolling
- Remove hover-only elements
3. Tracking issues that cost you money
#15 Broken cross-device tracking
People research on mobile but buy on desktop. Without proper tracking setup, these look like separate visitors instead of one customer journey.
How to fix it?
- Check your setup:
- Enable cross-device reports
- Set up User ID tracking
- Link Google Ads and Analytics
- Track key moments:
- First website visit
- Email or account creation
- Final purchase device
#16 Phone call black holes
Getting lots of calls but can’t track which keywords or ads drove them? You’re optimizing campaigns without key conversion data.
How do you fix it?
- Set up call tracking:
- Use Google’s call extensions
- Add dynamic number insertion
- Track call duration
- Link to campaigns:
- Track calls per keyword
- Monitor best call times
- Adjust bids based on call data
#17 Wrong attribution windows
Using default 30-day attribution when your sales cycle is 90 days? You’re cutting off crucial conversion data and making wrong decisions.
How do you fix it?
- Check your timing:
- Review sales cycle length
- Look at days to convert
- Set correct window length
- Adjust settings:
- Update attribution models
- Align across all platforms
- Include assisted conversions
#18 Hidden micro-conversion gaps
You track final sales but miss the small steps that lead there. Without micro-conversion data, you can’t spot where visitors actually drop off.
How do you fix it?
- Track key actions:
- Email signups
- Product views over 30 seconds
- Add to cart clicks
- Create funnels:
- Map expected user paths
- Monitor drop-off points
- Score actions by importance
