If a campaign is bringing in more leads while fewer become sales opportunities, changing the audience can feel like the obvious response. Sales is disappointed. Marketing has a report showing growth. Both teams want a decision.
I’d slow that conversation down just enough to ask what “poor quality” means in this case. Did the team speak to people who were a bad fit? Did the people stop responding? Or is the queue growing faster than anyone can work through it?
Those situations can produce similar-looking numbers. They call for different work.
First, agree on what actually fell
“Pipeline is down” can mean fewer qualified opportunities, a lower expected deal value, or fewer deals reaching a later stage. I’d put a name and a unit on the problem before discussing its cause.
For this article, the outcome is the number of qualified sales opportunities. The business needs an agreed rule for what counts as one. Submitting a form alone may not meet it. Revenue and pipeline value need their own checks; opportunity count cannot answer those questions for us.
Then I’d check whether the rule changed. Perhaps Sales now qualifies on a completed conversation rather than a form response. Perhaps a required field was added, duplicate records were removed, or the team became more consistent about recording a reason for rejection.
A change in the recorded result deserves investigation. It doesn’t automatically mean the people arriving have changed.
This is also where I would separate two questions: are we creating fewer opportunities in total, and is a smaller share of leads becoming opportunities? A falling rate can coexist with a rising count. The decision depends on which problem the business actually has, as well as what it costs to produce the result.
Give both groups the same amount of time
A lead created three days ago has had less time to speak to Sales than one created three weeks ago. Comparing their outcomes today gives the older group an advantage built into the report.
I’d group leads by when they entered and compare what happened after the same amount of time for each lead. If the observation window is fourteen days, measure both groups at day fourteen. Looking back at the older group means counting opportunities created by that point. A later win or loss should not erase an opportunity that had already qualified.
Compare leads at the same age
Illustrative timing. Each clock starts when the lead is created.
Compare both at day 3 now, or at day 14 once both have reached it. Count opportunities created by the matching point, using the older lead’s history.
Fourteen days is only an example. The useful window depends on the sales process. A business with a longer decision cycle may need a longer view, alongside earlier measures that show whether leads are progressing.
If the newer group has not reached the comparison point, I’d say so. There may still be enough evidence to repair an obvious routing error or a broken form. There is less evidence for a verdict on the whole campaign.
Check who makes up the total
Even a fair comparison can conceal an important change: the business may be attracting a different mix of people.
Consider this deliberately simple example. We count each person once, assign them to their first entry path, and allow one qualified opportunity per person in this example. We keep the qualification rule unchanged and count opportunities created within fourteen days of each lead’s arrival. These are illustrative figures, not results from a company or client.
More leads. A different mix.
Illustrative data · same qualification rule · 14 days per lead
Within each entry path, the observed rate is unchanged: demo requests 30%; guide downloads 10%.
View the figures
| Entry path | Earlier: leads / opportunities | Later: leads / opportunities |
|---|---|---|
| Demo request | 120 / 36 | 60 / 18 |
| Guide download | 80 / 8 | 240 / 24 |
Lead volume rose by 50%. Qualified opportunities fell from 44 to 42. The overall opportunity rate dropped eight percentage points, even though the observed rate for each entry path stayed the same.
The mix changed. Demo requests went from 60% of the leads to 20%, while guide downloads grew sharply. The overall rate reflects that shift.
Demo requests and guide downloads are entry paths, not acquisition channels. Each could contain paid search, organic search, referrals, or other sources. I’d examine those next if the split helped explain the change.
My first question here would be why demo requests fell, and whether the increase in guide downloads was intentional. I would also want to know what happened to those readers later.
These figures are not enough to decide where the next pound should go. They contain no acquisition costs, deal values, or later outcomes. They do show why an overall conversion rate is a weak basis for declaring that every part of acquisition has deteriorated.
Follow a few leads through the handoff
Once the timing and mix are understood, I’d open the records behind the result. The useful detail might be in a form response, the first contact attempt, an unanswered message, or a note from the person who spoke to the prospect.
Start with a small set across the relevant outcomes: qualified, rejected, unreachable, and still waiting. Use it to find explanations worth checking across the wider group. A handful of records can expose a process problem; it cannot establish how common that problem is.
I’d look for the point where a lead stopped progressing. Was the contact information usable? Did the lead reach the right owner? Was there a contact attempt? Did the person respond? If a conversation happened, what specifically made the opportunity unsuitable?
“No answer” tells us something about reachability. “Outside the service area” tells us something about fit. “No contact attempt recorded” leaves a question about the process. Combining all three under “bad lead” makes the next decision harder.
It is worth checking the gap between what the campaign offered and what the person expected, too. Someone who asked for a guide may be surprised by an immediate sales call. The record can help explain that mismatch without requiring either team to guess the other’s intentions.
Make the next change specific
By this point, I’d want to be able to finish a sentence: the difference appears here, and this is the evidence we have for it.
That determines the next action. If comparable leads are waiting unworked, investigate routing and capacity. If poor-fit reasons cluster around one offer or audience, review that part of acquisition. If the difference disappears when groups are compared at the same age, correct the reporting before drawing a campaign conclusion.
Find the next useful check
Work through the evidence in order. More than one issue can be present.
- 01Definition
Are both groups being judged by the same rule?
Check the qualification criteria and how they were recorded.
- 02Time
Has each lead had the same observation window?
Rebuild the comparison at a shared age.
- 03Mix
Did the balance of entry paths change?
Separate volume changes from changes in the rate.
- 04Handoff
Where did progress stop?
Check ownership, contact attempts, responses, and fit reasons.
I’d write down the proposed change, who owns it, what result would support the diagnosis, and when the comparison will be meaningful. Keeping the change narrow helps the team learn from the outcome. Any other changes happening at the same time belong in the review as well.
Five questions to take into the review
- What outcome changed, and are we using the same definition in both groups?
- Has every lead had the same amount of time to reach that outcome?
- How much of the difference comes from a change in the mix of leads?
- Where do the records show progress stopping, and how widespread is it?
- What is the smallest useful change we can evaluate, with an owner and a review date?
