Reddit detour distorts PPC signals

At $50+ CPCs, Reddit beat every marketer by default 67.3% of the time for all 8,566 keywords.
Research from Ross Simmonds and his team focuses on B2B SaaS, but the potential doesn’t stop there. If the competition for advertising is high at the time, it is possible that the Reddit thread stays above the rest of the product in the organic results.
If you are in legal, financial services, paid home services, or insurance, those CPCs are not unusual places. This study should pay attention.
The SEO community has been talking about this for a while, and the conversation has been mostly in the SEO space: Reddit eats organic search, so build your list and invest in a content strategy. These are great suggestions, but I’m not an SEO, so I can’t speak to them.
What I always think about is not mentioned in the research: What does this actually do to the signal your PPC campaigns depend on?
The problem begins before anyone clicks on your ad
When a buyer searches for a keyword with high intent and lands on a Reddit thread instead of your page, two things happen.
- The buyer gets peer reviews, real comparisons, and information from people who have already been where they are.
- Google records a behavioral signal: someone searched for this query, engaged with this result, and did not need to continue.
That signal feeds back into Google’s understanding of what satisfies that query, and over time, shapes how the algorithm models match that term.
Your page doesn’t just lose clicks. Contribute to the pattern of signal reduction in terms that you are working hard to pay the competition for, that appear outside of your account completely, without a report that appears.
This is what makes automation drift a problem. The algorithm updates its model based on the behavioral data it sees, while your account operates in the dark about where that data came from.

The problem continues after someone clicks
A consumer who spent three days on Reddit before clicking your ad comes across as a different person than someone who searched and converted in the same session. They’ve compared options, read real-world experiences, and already filtered out most of the noise.
Smart Bidding has no knowledge of what happened. It sees a $50 click and waits to see that conversion ignite within your attribution window.
If you use a short window and the buyer spends a few of those days in the research phase before returning, you are looking at 100% cost and no conversions are still sitting in that cycle.
The system interprets this as a malfunction and begins to go back to the specific goals that generate your most qualified buyers, not because something went wrong inside the account, but because the signal that was given to it was told to it.
Automation does what it was designed to do. The signal does not show the full picture of what is happening.
What UCaaS gets right others don’t
Simmonds’ research includes four verticals. In three of them, Reddit beat every other seller at the same time by more than half of the keywords shared.
In the unified communications and contact center as a service (UCaaS) segment, vendors are winning. RingCentral, Nextiva, and Dialpad consistently beat Reddit on the same terms where all is lost.
It is not because of domain authority or budget. They’ve been building informational content for years – glossaries, category descriptors, selection guides – and they haven’t stopped. Google has something real to show for those terms beyond the ad, and the behavioral signals in those queries reflect that.
That’s content investment discussion, and useful. But the goal is directly connected to the bidding side: the algorithm makes better decisions when the signals around the word are clean, and clean signals do not happen by chance.

Where repairs reside
On the bidding side, offline conversion tracking is a way to close the gap.
When you feed the downstream results back into the algorithm – qualified leads, closed leads, and what was really worth it – you give Smart Bidding the context it needs to understand that a long, hard path of research at a higher CPC can still be the right result.
Google’s own data shows a 10% higher average conversion rate for advertisers who use first-party data around click IDs for offline measurement. Without it, the system continues to evolve on the fastest path to change, which is rarely the path taken by your most savvy consumers.
On the organic side, getting more targeted about where your business is coming from the conversations your buyers are already having is worth considering.
That might mean investing in content that actually answers the questions a Reddit thread is currently answering, or thinking about whether your business exists in the communities where your consumers are doing their research.
UCaaS vendors didn’t beat Reddit by outspending everyone. They beat it by consistently appearing in the right places with the right content, long before anyone is ready to click on an ad.
The terms you use most of the time are the same words that Reddit probably sits between your ad and your buyer, silently shaping the signals that depend on your automation.
That’s what automation drift looks like when it starts completely out of account.
