Quick Answer: Bad PPC Campaigns Become Worse Over Time Due to Account Dynamics
A poorly configured Google Ads account doesn't just underperform. It actively degrades as the algorithm learns to match bad keywords with wrong audiences.
Understanding this feedback loop lets Vancouver businesses identify when they're in a death spiral and how to escape it.
How the PPC Death Spiral Works
Month 1: Campaign launches. Broad match keywords enabled. Budget spread thin across 10 campaigns.
Problem: Algorithm matches keywords to irrelevant searches (problem searches, location-irrelevant, audience-wrong). These clicks produce no conversions. Algorithm observes: "This account converts poorly."
Month 2: Algorithm response. Quality Score drops. Cost per click increases (low QS = higher CPC). Conversion rate stays the same or drops (still getting wrong traffic).
Month 3: Feedback loop accelerates. Higher CPC + same low conversion = worse ROAS. Account manager increases bid to maintain position. Higher spend, same low conversions.
Month 4: By now, the account is trapped. High spend, low conversions, declining performance, desperate increases to "fix" the problem actually worsen it.
Month 5-6: Death spiral complete. Budget exhausted. Conversions stagnant. Client fires agency or vice versa.
The Escape Routes
Escape 1: Surgical Campaign Reconstruction
Don't salvage the existing account structure. Build 3-5 new campaigns from scratch with surgical targeting: one for branded searches (high conversion, lower spend), one for commercial intent (medium spend, medium conversion), one for awareness (lowest spend, future pipeline).
Keep the old campaigns running on minimal budget. Don't pause them (existing volume loss looks bad in reporting). Instead, reduce them to skeleton crews while new campaigns ramp up.
Timeline: Week 1-2 rebuild, Week 3-4 ramp new campaigns, Week 5-6 monitor, Week 7-8 pause old campaigns once new ones perform.
Escape 2: Algorithm Reset via Conversion Data Refresh
Google's algorithm learns from conversions. If it's been learning from poor conversion data (clicks with no conversions), reset that learning by: (1) Implement conversion tracking correctly (many accounts track wrong conversions), (2) Ensure offline conversions are being imported (phone calls, in-person visits), (3) Link Google Ads to Analytics properly so algorithm sees true conversion data.
Often, the account isn't actually underperforming. The algorithm just doesn't know which clicks actually converted. Fixing this alone improves performance 15-30%.
Escape 3: Landing Page Overhaul + Bid Strategy Pivot
Move all traffic to keyword-specific landing pages (not homepage). This immediately improves conversion rate 20-30%. Algorithm observes higher conversion rate. Quality Score improves. CPC drops. Even with same traffic, ROAS improves.
Simultaneously, switch from manual bidding to target ROAS or target CPA. Let algorithm handle bid optimization instead of humans guessing.
Recognition Checklist: Are You in a Death Spiral?
Signs: Declining conversion rate (month-over-month), increasing cost per conversion, Quality Score below 6/10, high % of traffic from broad match keywords, landing pages are generic (homepage, not keyword-specific), no offline conversion tracking, geographic targeting too broad.
If you see 3+ of these, you're likely in a death spiral. The fix requires decisive action, not incremental optimization.
