Leads
In marketing and sales, a lead is a person or organisation that has expressed interest in a product or service and provided contact information that makes them identifiable and reachable. A lead might have submitted a contact form, downloaded a piece of content, registered for a webinar, or requested more information. Whatever the trigger, the defining moment of becoming a lead is the exchange of contact information, transforming an anonymous visitor into a known individual who can be communicated with directly.
Not all leads are equal. Raw leads, sometimes called information-qualified leads, have simply provided their details without any strong signal of purchase intent. Marketing Qualified Leads (MQLs) have demonstrated meaningful engagement signals that suggest genuine interest. Sales Qualified Leads (SQLs) have been assessed by sales and confirmed as viable opportunities. The progression from raw lead to SQL represents increasing confidence that the prospect will convert, and each stage requires different nurture and follow-up approaches.
For B2B marketing teams, lead quality is as important as lead quantity. Generating a high volume of poorly qualified leads creates more work for sales without proportionally more revenue. The goal is to generate leads that genuinely match your ideal customer profile, have a real need for your solution, and are at a stage in their journey where they will respond to nurture and sales outreach. Defining, measuring, and optimising for lead quality rather than just volume is a hallmark of a mature B2B marketing programme.
What is the difference between a lead, a prospect, and an opportunity?
A lead is someone who has provided contact information and shown some level of interest but has not yet been qualified. A prospect is typically a lead that has been assessed and meets basic qualification criteria, making them worth pursuing. An opportunity is a qualified prospect who has been engaged by sales, confirmed as having budget, authority, need, and timeline, and entered the sales pipeline as a potential deal. The terms are used differently across organisations; what matters is having a clear, shared definition within your team.
How quickly should leads be followed up?
Research consistently shows that speed of follow-up dramatically affects conversion rates. Leads contacted within minutes of submitting a form are significantly more likely to convert than those contacted hours or days later. In practice, immediate automated follow-up through email should fire the moment a form is submitted. Human sales follow-up for high-intent leads should happen within hours. For lower-intent inbound leads, a structured nurture sequence is a more scalable approach than attempting immediate human follow-up on every submission.
What is lead hygiene and why does it matter?
Lead hygiene refers to the ongoing maintenance of lead data quality in your CRM and marketing database. It involves removing or correcting duplicate records, updating outdated contact information, suppressing contacts who have opted out or hard bounced, and ensuring that fields like company size, industry, and job title are populated accurately. Poor lead hygiene means nurture emails go to the wrong people, lead scores are calculated on inaccurate data, and sales follow up on contacts who should not be in the active pipeline.
