The funnel metrics that actually matter

The metrics most founders track are the ones that are easy to see, not the ones that tell them what to do next. Total emails sent, total impressions, total website visitors — these are inputs, not outcomes. The metrics that tell you where your pipeline is breaking, and therefore where to spend your next hour, are the conversion rates at each stage.

The metrics to track, in order:

Awareness metrics — impressions, reach, engagement rate. These tell you whether your content is earning attention. An engagement rate below 1% on LinkedIn organic content suggests a relevance problem with the audience or a quality problem with the content. An impressions trend is the leading indicator for everything downstream.

Acquisition metrics — click rate, email reply rate, cost-per-click. These tell you whether your message is compelling enough to earn an action. A reply rate below 2% on cold email suggests a targeting problem (wrong ICP), an offer problem (wrong angle), or a deliverability problem (not landing in inbox). The click rate on paid ads tells you the same thing about creative and targeting.

Qualification metrics — lead-to-meeting rate, meeting-to-qualified-meeting rate, lead score distribution. These tell you whether you are talking to the right people. A high meeting volume with a low qualified rate is a targeting problem that no amount of follow-up will fix.

Conversion metrics — meeting-to-proposal rate, proposal-to-close rate, sales cycle length. These tell you whether your offer, your process, and your positioning are working. A founder closing at 15% on qualified meetings has a different problem than one closing at 45%.

The one metric to live by. For a solo founder at early stage, the single most useful number is cost-per-qualified-meeting (not cost-per-lead, which is gamed by volume). It forces you to account for both acquisition cost and qualification rate, and it connects directly to your unit economics. If your average contract value is £10,000 and your cost-per-qualified-meeting is £500, you can build a model. If it is £2,000, you need a different channel mix.

2025 benchmarks across channels:

• Cold email: £30–£80 per lead, £200–£500 per qualified meeting
• LinkedIn organic: effectively £0 per lead (time cost only), conversion depends heavily on offer and nurture
• LinkedIn paid: £60–£120 per lead, £300–£600 per qualified meeting
• Paid search: £80–£200 per lead, £400–£800 per qualified meeting
• SEO (mature): £5–£20 per lead (at scale, amortising content production cost)
