Lead Quality vs Quantity: Why More Leads Is the Wrong Goal

Lead quality versus quantity is one of the oldest arguments in marketing, and most teams are still losing it. The short answer: more leads is rarely the right goal. A smaller pipeline of well-qualified prospects will almost always outperform a larger one filled with people who were never going to buy.

The longer answer is that the debate itself is often a symptom of a deeper problem, where sales and marketing are measuring different things, optimising for different outcomes, and blaming each other for the gap in between.

Why Most Teams Default to Volume

There is a structural reason marketing teams chase volume. When the primary KPI is leads generated, the rational response is to generate more leads. Lower the friction, broaden the targeting, reduce the qualifying criteria, and the numbers go up. The dashboard looks healthy. The quarterly review goes smoothly.

I have seen this pattern repeat across industries. When I was running agency teams, we would sometimes inherit accounts where the previous agency had built an impressive-looking lead machine. Hundreds of enquiries a month. Conversion rates that looked fine on paper. But when we dug into the sales data, the close rate was negligible, average deal size was shrinking, and the sales team had quietly stopped following up on most of the leads because they had learned, through painful experience, that they were not worth the time.

The marketing team was hitting its targets. The business was not growing. That gap is where the quality versus quantity problem lives.

Volume-led thinking is also reinforced by how most paid media platforms are optimised. Algorithms reward engagement and click-through. Bidding strategies optimise for conversion events, which are often defined as form fills rather than qualified opportunities. The platform does exactly what you ask it to do. If you ask it to find people who will complete a form, it will find people who complete forms. Whether those people have any intention of buying is a separate question you have to answer yourself.

What Lead Quality Actually Means

Lead quality is not a feeling. It is a measurable characteristic, and it has to be defined before you can optimise for it. The problem is that most organisations have not done that work explicitly. “Quality leads” means different things to different people in the same building.

A useful definition has three components. First, fit: does this prospect match the profile of a customer who is likely to buy and likely to stay? Second, intent: is there evidence of active purchase consideration, not just curiosity? Third, timing: is this prospect in a position to make a decision within a reasonable window?

These criteria should be agreed between sales and marketing before a campaign launches. In practice, they rarely are. Marketing builds targeting based on audience data and platform signals. Sales defines a good lead based on conversations they have had and deals they have closed. The two sets of criteria are often not the same, and nobody has sat in a room long enough to reconcile them.

This is partly a process failure and partly a cultural one. Marketing and sales are frequently measured on different things, which means they are incentivised to optimise for different outcomes. The most effective go-to-market teams I have worked with treat lead definition as a shared document, reviewed quarterly, signed off by both functions. It sounds basic. It is also surprisingly rare.

If you are building or refining a go-to-market approach, the broader thinking on go-to-market and growth strategy covers how lead generation fits into a commercially coherent growth model.
