Strategy review & optimization
Top KPIs marketers prioritize overall (2026)
| KPI | Share of marketers prioritizing it (%) |
|---|---|
| Lead quality and MQLs | 39% |
| Lead-to-customer conversion rates | 34% |
| Return on marketing investment | 31% |
| Customer acquisition cost | 30% |
| Lead generation volume | 29% |
- Reader Note:
- 39% put this first, which makes it the largest single answer rather than one most marketers chose. Lead quality and MQLs are bundled as one option in the question, so the two cannot be separated — a team tracking MQL volume and a team tracking lead quality answer the same way.
- Evidence:
- Self-reported behaviour
- Vendor interest:
- Moderate — This comes from a company with a commercial interest in this market, so it is not a neutral source.
- Sample:
- HubSpot surveyed 1,505 marketers in September 2025 across North America, Europe, Asia and Australia, spanning seniority levels and industries; fieldwork run in collaboration with the research firm Datalily. The report does not disclose how the sample splits by region, industry or seniority, so every published figure is a single global average. It does report cuts by company size - small business, mid-market and enterprise.
Good for
A rough sense of size and direction, and deciding what to look at first.
Not for
- Exact numbers, or saying that one thing caused another.
- This is an aggregated or average number that covers very different cases. Real results in a particular segment may differ.
- This comes from a company with a commercial interest in this market, so it is not a neutral source.
- The source never says how this number was measured.
- The source says how much it looked at, but not how any of it was chosen.
