Something strange is happening in Google Ads accounts across the board: click-through rates are going up, but conversion rates aren't following. If you've noticed more traffic from your campaigns without a corresponding lift in revenue, you're not imagining it — and you're not alone.
New data from Optmyzr's latest industry report puts numbers to what many performance marketers have been feeling. CTR is rising. Efficiency — measured by cost per conversion — is holding flat at best, declining at worst. The disconnect is real, and it has a structural explanation.
The Numbers Behind the Gap
Optmyzr's analysis across thousands of Google Ads accounts shows:
- Average CTR increased year-over-year across Search, Shopping, and Performance Max
- Conversion rates remained flat or declined slightly in the same period
- Cost per conversion held stable only in accounts with active negative keyword management and tight match type strategy
The surface-level interpretation — "more clicks, same conversions, therefore lower conversion rate" — is correct. But the why behind it is more instructive than the stat itself.
Three Reasons Your CTR Is Up But Conversions Aren't
1. Broad Match Is Serving More Aggressively
Google has been expanding the reach of broad match keywords for years, but the pace accelerated significantly in 2024–2025. Combined with Smart Bidding, broad match now interprets queries far more liberally than the keyword intent you originally set.
The result: you're getting clicks from searchers who are topically adjacent to your product but not actually in buying mode. Someone searching "how to improve ROAS" clicking an ad for a ROAS analytics tool is a valid broad match. But they're researching, not buying. Your CTR goes up. Your conversion rate goes down.
The fix isn't to abandon broad match — it's to build the negative keyword structure that protects it. Broad match without aggressive negatives is a budget leak disguised as reach.
2. Performance Max Is Absorbing Brand Traffic
PMax campaigns have a well-documented tendency to serve on branded queries unless you explicitly exclude them. Brand searches convert at 2–5x the rate of non-brand searches. If PMax is stealing branded traffic that would have converted anyway, it inflates your PMax conversion numbers while masking the true picture.
Meanwhile, non-brand clicks — the harder, more expensive ones — aren't converting at the rate your blended numbers suggest, because the brand halo is covering the gap.
Check this by segmenting your conversion data by query type. If branded queries make up more than 30% of your PMax conversions, your non-brand efficiency is likely worse than your dashboard shows.
3. Landing Page Experience Hasn't Kept Up
This one is uncomfortable but important. Google's algorithm has gotten significantly better at matching user intent to ad copy. The CTR improvement you're seeing is partly evidence that your ads are more relevant than they used to be. But if the landing page experience doesn't deliver on the ad's promise — if there's a mismatch between what the ad says and what the page shows — clicks don't convert.
Page speed is the measurable proxy here. A 1-second delay in mobile load time reduces conversion rate by approximately 20% on average. If your CTR is rising but your page hasn't been optimised, you're generating qualified interest and then losing it at the door.
The Bid Strategy Dimension
There's a subtler issue underneath all of this that the Optmyzr data points toward: Smart Bidding optimises for conversion volume, not conversion quality, unless you configure it explicitly otherwise.
If you're using Target CPA or Target ROAS with a broad definition of "conversion" — including micro-conversions like email signups or page engagement — the algorithm will find clicks that hit those signals, regardless of whether they lead to actual revenue.
Accounts that are seeing CTR rise without revenue lift often have a conversion definition problem. The machine is optimising toward what you told it to optimise toward. If you defined conversion loosely, you'll get loose results.
What to audit:
- Are all your conversion actions tied to actual revenue events?
- Is your primary conversion action set as the sole optimisation target, not a blended mix?
- Have you excluded micro-conversions from Smart Bidding inputs?
What to Do This Week
Three concrete actions based on the Optmyzr findings:
1. Pull your search term report and build a fresh negative keyword list. Focus on informational intent queries (how, what, why, guide, tutorial) that are eating clicks without converting. Add them as negatives at the campaign or account level.
2. Segment your PMax conversions by branded vs non-branded. In the Insights tab, look at search category data. If branded terms are dominant, create a brand exclusion list in your PMax settings.
3. Check your conversion action configuration. In Google Ads → Tools → Conversions, confirm that your Smart Bidding campaigns are optimising to purchase or lead events only — not page engagement or session duration.
These three actions alone will often close 60–70% of the gap between CTR improvement and flat conversion performance.

The Bottom Line
Rising CTR with flat conversions is a signal, not a crisis. It usually means your ads are reaching more people, but structural issues — broad match without negatives, PMax brand blending, or conversion definition problems — are absorbing the gains before they reach your bottom line.
Fix the structure, and the conversions follow.
