You can usually feel it before you can explain it. Costs inch up. SQL quality softens. Retargeting that used to hit every week suddenly feels flat. Nothing is completely broken, but nothing is really moving either. If you’ve run LinkedIn ads long enough, you know that moment.
And here’s what most people miss. LinkedIn didn’t suddenly get pricier. Your strategy drifted. It happens slowly, then all at once.
After analyzing LinkedIn ad campaigns from 200+ B2B SaaS accounts, we found some narratives that flip the narrative around advertising:
- Signal-based targeting averages a 0.875% CTR
- Only 2.99% of clickers even open the form
- Native forms sit around $810 CPL, while external averages $221
- 75% of campaigns pay more than $6 CPC
- Multi-touch retargeting converts 2.5x higher than basic retargeting
Once you see the benchmarks, spotting the signs gets a whole lot easier.
Signs Your LinkedIn Ad Strategy Needs Fixing
1. Your CPC is Climbing Above $6 With No Lift In SQLs
When your CPC pushes past six bucks, and nothing downstream improves, your targeting is off. Not slightly off. Fully misaligned with buyer intent. After analyzing over 200 B2B SaaS accounts, we found that about 75% of advertisers sit above this threshold because they target demographics instead of signals. Job titles, seniority, and company size. All the usual suspects that look clean on paper and waste money in practice.
High CPC by itself isn’t the problem. High CPC with flat SQLs is. That gap tells you your ads are attracting the wrong people or hitting the right people at the wrong time.
Signal-based targeting changes this. Instead of hoping your filters catch someone in a buying cycle, you target behavior that actually indicates interest. Pricing page views. Repeat sessions. Competitor research. That’s the stuff that moves pipeline.
Tools like DemandSense make this simple because you can see which accounts are showing intent instead of guessing with job titles. Once you shift from demographics to signals, CPC becomes a lot more predictable, and SQLs start to match spend.

2. Your CTR Dropped Below 0.5%
CTR is one of the fastest ways to spot when your message isn’t landing. LinkedIn’s platform average sits around 0.52%. Our clients running signal-based targeting hit closer to 0.875%. So when you see your CTR slide under 0.5%, that’s a clear sign your message-market fit is off.
This usually happens for two reasons. Your creative is fatigued, or you’re serving the wrong message to the wrong stage of the funnel. Both problems look the same on the surface, but the cause matters.
If your TOFU CTR falls below 0.45%, don’t scale. Stop and diagnose the message. Cold audiences will tell you very quickly if your hook isn’t strong enough or if your angle feels generic.

3. You’re Still Using One Giant Retargeting Audience
If your retargeting is built around one big bucket like “website visitors 180 days,” you’re basically guessing. Intent doesn’t stay constant for half a year. Someone who hit your pricing page yesterday is not in the same mindset as someone who skimmed a blog three months ago. Treating them like they are flattens conversions fast.
When you break your retargeting into clear recency segments—0 to 30 days, 30 to 60 days, and 60 to 90 days—performance improves immediately because your message actually matches where the buyer is in their cycle.
Multi-touch retargeting shines here. Across the accounts we analyzed, multi-touch sequences drove about 2.5x higher conversions than single-layer retargeting. The difference is simple. You’re not just reminding people you exist. You’re meeting them with the right asset at the right time.
If your retargeting hasn’t produced anything meaningful lately, odds are the audience is too broad, too stale, or both.
4. Your Form Open Rate Is Under 3%
This one surprises a lot of advertisers. Our data shows that only 2.99% of clickers even open a form. But once they do, about 23.1% submit it. So the form isn’t the problem. The leak happens before the form ever loads.
If your CTR looks solid but your form open rate is sitting under 3%, the ad promise and the landing page aren’t speaking the same language. The buyer clicked for one reason and landed on something that didn’t back it up. Wrong angle. Wrong headline. Wrong expectation.
You’re paying for the right traffic, but you’re losing them in the first three seconds. Fix the landing page message, not the form fields.
5. Native Forms Are Filling Your CRM But Not Your Pipeline
Native forms look great in the dashboard. Cheap clicks, lots of names, plenty of activity. Then you check the downstream numbers and realize almost none of it turned into pipeline. This is the classic native form trap.
After analyzing performance across our client base, native forms sit around an $810 CPL, while external conversions average $221. The cost gap is huge, but what happens after the form is the bigger issue. Native forms inflate lead volume and crush SQL quality because people can submit without ever engaging with your site or your message.
If sales keep rejecting leads or marking them unqualified, your acquisition model is off. You’re optimizing for the wrong conversion point. Get the buyer to your site, let them interact with your content, and track the signals that actually predict pipeline.
Native forms give you a name. External conversions give you intent. Pipeline follows intent every time.
6. Your Creative Has Been Live Longer Than 4–8 Weeks
Creative fatigue doesn’t hit all at once. It sneaks up on you. CTR slips a little. CPC climbs a little. Nothing looks broken, but the whole system starts dragging. If you’ve been running the same assets for more than a few weeks, this is probably why.
Here’s what we’ve seen across hundreds of campaigns:
- Single image ads fall off around weeks 4 to 8
- Carousels start fading around week 7
- Video holds until about week 9
- Thought leadership ads can run close to 12 weeks
If your CTR is slowly eroding and your CPC keeps creeping upward, your creative is tired. Not bad. Not useless. It’s just seen too many times by the same people. Once frequency climbs and engagement drops, LinkedIn throttles distribution, and you end up paying more for the same traffic.

Rotating creative before it dies will save you more budget than tweaking bids ever will.
7. You’re Burning Through Your Best Audiences Without Refilling Them
This is one of the most common plateau patterns. Retargeting looks great in the first few weeks, then everything falls off a cliff. Costs climb. Conversions tank. And nothing you change inside the campaign seems to fix it.
The problem isn’t the ads. It’s the audience.
If your retargeting pool stays the same size month over month, you’re exhausting your highest intent buyers without replacing them. Frequency climbs to eight, ten, sometimes twelve impressions per person. At that point, you’re not nurturing. You’re chasing people who already made their decision.
Warm first-party data is always your most efficient CPL tier. But it only stays efficient when new people enter that pool. If your cold traffic isn’t feeding the middle and bottom of your funnel, your best audiences eventually dry up.
Strong early retargeting followed by a sudden performance drop is the giveaway. You’re burning through intent, not building it.
8. You’re Using Conversion Ads On Cold Audiences
If you’re running conversion ads to cold audiences, you’re paying premium prices for people who don’t even know who you are. Funnel mismatch is one of the biggest budget leak sources on LinkedIn, and it shows up fast in the numbers.
Looking at performance across funnel stages:
- TOFU sits around 0.45% to 0.9% CTR
- MOFU form fills land in the 8% to 18% range
- BOFU demo booking rates hover around 3% to 6%
Cold users don’t behave like warm users. So when they see a BOFU “book a demo” message on the first touch, they scroll. And if they don’t scroll, you pay through the nose to get them on a form they’ll never complete.
This is how advertisers end up with $500 to $600+ CPL without realizing the real issue isn’t the audience or the offer. It’s the stage mismatch.
Cold traffic is for hooks and education. Warm traffic is for conversion. Mixing the two is the fastest way to burn money and blame the platform.
9. You’re Chasing Engagement Instead of Signals
If you’re still optimizing for likes, comments, and vanity metrics, you’re flying blind. Across the accounts we analyzed, the correlation between engagement and actual leads came in at -0.0018. That’s not low. That’s zero. Engagement tells you nothing about buying intent.
Reactions are noise. Signals are what matter.
Pricing page visits. Repeat sessions. Depth of content consumption. Those behaviors map to pipeline. A post getting 200 likes doesn’t mean anything if none of those people moved deeper into your funnel.
When advertisers chase engagement, they usually end up building audiences full of people who like their content but are never going to buy. DemandSense makes the difference obvious because you can see what the engaged accounts actually did on your site. Spoiler: most of them didn’t do anything.
If your targeting and optimization revolve around reactions instead of signals, expect high engagement numbers and dead pipeline. Every time.
10. Your Video Strategy Is Missing Or Built Wrong
Video is one of the easiest ways to warm cold traffic, yet almost nobody uses it correctly. Looking at advertisers running LinkedIn campaigns, only 15.4% even run video. Of the ones who do, the average completion rate lands around 33.6%. That’s a lot of buyers getting a full dose of your message without ever clicking.
The trick is building it right. Your hook has to hit in the first three seconds. If it doesn’t, you lose the scroll and the whole asset becomes a very expensive impression.
Video is the bridge between TOFU and MOFU. It moves people from cold to warm in one clean step. If you don’t have video in your funnel, or you’re using it in the wrong place, your cold traffic never becomes retargeting-ready. No education, no depth, no warm pool to work with.
Sign to watch for: if your funnel jumps straight from cold prospecting to hard conversion ads, your sequence is broken. No video means no transition layer, which means your retargeting has nothing strong to work with.
11. SQL Costs Climb Above $450
Your SQL cost tells the truth faster than any other metric. Looking at healthy BOFU performance, SQL costs land in the $200 to $450 range. Once you cross that line, something in the lower funnel is out of sync.
There are three usual causes:
- Warm audiences dry up and the platform ends up converting people who aren’t ready
- The offer doesn’t match where buyers are in their evaluation
- The retargeting sequence skips key steps, so prospects never see the proof they need before booking
When SQL cost climbs above $450, it’s rarely a bidding issue. The warm layer isn’t doing its job or the offer isn’t strong enough for educated buyers. Fix the sequencing, and SQL costs drop back into a healthy range fast.
12. You’re Scaling TOFU Before Fixing “Bucket Leaks”
When performance dips, a lot of teams try to brute force their way out by pumping more money into cold traffic. More impressions, more clicks, more volume. It feels like the right move until you look at the pipeline and realize nothing improved. This is the fastest way to burn budget on LinkedIn.
You don’t scale TOFU until the MOFU to SQL path is actually working. If the middle and bottom layers aren’t converting efficiently, all you’re doing is pouring more cold users into a system that can’t move them forward. Spending goes up. Pipeline stays flat.
This is why fixing the sequencing matters more than fixing the volume. Once MOFU education and BOFU proof points are doing their job, scaling TOFU works. Until then, it’s just an expensive distraction.
Final Thoughts
Most LinkedIn strategies don’t fail overnight. They slide. A small dip in CTR here. A little spike in CPC there. Retargeting stops pulling. SQL quality softens. These signs show up long before performance hits a wall, but only if you know what to look for.
Every issue in this list is fixable. Once you see where the funnel slipped out of sync, the path back to strong performance gets a lot clearer.
