Good PPC campaigns suddenly stop working - why?

ctrjunkie

I love marketing but sometimes I want to throw my laptop out the window. Had a few campaigns performing consistently for months, then boom - results drop hard with zero major changes. No edits to targeting, keywords, budgets, creatives. Yet CPC shoots up, leads vanish, conversion rate goes down, impressions get unstable. It's maddening.

Before I start randomly optimising and making things worse, I want to know what you guys check first. Is it audience fatigue? Competition? Algorithm shift? Tracking issues? I've noticed performance getting more volatile lately - anyone else?

I saw someone else say they went from 6 leads a day for two weeks straight to zero for a week - same account, same creatives, same budget. Someone else asked what specific campaign types I'm running. But honestly, when performance tanks without changes, how is that not the platform optimising against you? Would love to hear from other advertisers and agency owners who've dealt with this.

Yep. Had a campaign drop from six leads daily for two weeks straight to zero for a whole week. Infuriating.

Oh honey, that question is so broad it needs its own zip code. First thing I'd check depends entirely on the platform and campaign type - audience fatigue, rivals sneaking in, or just Meta being its usual garbage self. So, spell it out for me: what specific campaign types are you running on each platform? I can't read tea leaves (yet).

It's maddening, isn't it? Same account, same creatives, same budget - and performance just drops off a cliff. 🤷‍♀️ Would love someone to explain how that's not the platform actively working against you.

One thing worth double-checking: your impression loss to rank. Has your website been optimised for LLMs yet? And are you using AI Max on your search campaigns? Those are often the hidden culprits when performance drops suddenly.

Tell me about it! PPC performance is nowhere near as stable as it was a few years ago. I've seen perfectly optimised campaigns suddenly tank with no obvious changes in the account. It's baffling - and honestly pretty frustrating. 👎

Have you tried to check your competitors?
What's in the Auction insights reports? Is there a fluctuation? Do you have a new competitor? Do your current competitors have better offer now?

Check auction insights first a new competitor is the most common cause of sudden performance drops without account changes

Hard to say without knowing the niche.

Different verticals behave differently - e-commerce usually sees seasonal fatigue, B2B often suffers from audience saturation, lead gen can tank if intent signals shift.
GA4 migration introduced new attribution models that can make campaigns look like they've dropped off when they haven't.
Also check if your conversion tracking is still firing correctly - I've seen broken GA4 event tags cause sudden volume drops that looked like campaign failure.

which niche exactly? The diagnosis changes a lot based on that

It’s not audience fatigue. Audience fatigue shows more gradually. What OP is talking about is an abrupt drop. Overnight.

I’ve experienced this in 3 different accounts in 3 entirely different industries.

They were all PMAX campaigns.

The week it happened I received an urgent email from my Google ads rep which said “I’ve seen a major issue with your ads and have a resolution I need to share with you. Set up a meeting on my calendar.”

Skeptical, I did it anyway for one of the accounts.

The rep had nothing to share except going through the automated recommendations with me. So I asked about the email where he said he knew what was wrong.

He said “oh, I didn’t write that email. They’re automatically sent. I reviewed your account though and here are the recommendations you can do.”

I was so pissed off. It really felt like Google intentionally killed the performance to get me to stop ignoring their emails from ad reps.

Again, all 3 accounts had this exact pattern. I ignored the other two.

But something the guy said made me think. He said something about kicking the campaign back into learning mode.

So I increased the budget by 50% for 24 hours, then decreased back down the next day. Within 2 days the performance level returned.

I did the same on all three accounts and had the same results.

So, perhaps make a change that will trigger the learning process, but won’t impact your ad copy. Budget changes can do this I believe.

Interesting, thanks for the tip! I had the same issue recently and went through the same confusing google rep call. I was looking into other causes, including bots but this might be the reason. I'll definitely test your "budget bump" method.
