Lead Generation

Lead generation is the set of marketing and sales activities that create interest from, or identify, potential customers and capture enough information to follow up with them, feeding the top of the sales pipeline.

In short

Lead generation fills the top of the funnel with potential buyers you can follow up with.

Key points

  1. Wikipedia defines lead generation as the initiation of consumer interest or inquiry into a business's products or services [1].
  2. It includes inbound methods such as content, search and webinars, and outbound methods such as Cold Email and calling [2][4].
  3. Leads are then filtered with Lead Scoring and Lead Qualification into MQLs and SQLs.
  4. Consultancies and studios run the same playbook to win clients; see agency client acquisition.
  5. Key cost measures are Cost per Lead (CPL), Cost per Meeting and ultimately Customer Acquisition Cost (CAC) [3].
  6. Volume without fit hurts: poorly matched leads lower Conversion Rate and waste sales time.
  7. B2B lead generation that uses personal data must respect rules such as GDPR and the CAN-SPAM Act.

Inbound and outbound lead generation

Lead generation methods fall into two broad groups. Inbound marketing attracts people who are already looking, through articles, search, webinars, free tools and a Free Trial; the lead arrives by filling in a form or signing up [4]. Outbound lead generation starts with the seller choosing companies that fit an Ideal Customer Profile (ICP), or that form a Lookalike Audience of existing customers, and contacting them first, most often by email. Salesforce describes lead generation as attracting and converting strangers into people who have shown interest, and notes that both approaches are commonly combined [2]. Inbound tends to be slower to build but cheaper per lead over time, while outbound gives direct control over which accounts are approached and how quickly.

Measuring what works

A lead generation program should be judged by what happens after the lead is captured. Track how many leads become meetings, opportunities and customers, then divide spend by each to get Cost per Lead (CPL), Cost per Meeting and Customer Acquisition Cost (CAC). Mailchimp's guidance emphasizes nurturing and qualifying leads rather than simply collecting contact details [3]. Attribution models help assign credit when a buyer touches several channels before converting. Compare channels on the same downstream metric, because a channel that produces fewer but better leads can easily win on revenue. Review lead quality with sales regularly, since agreement on what a good lead looks like is the main lever for improving Conversion Rate [1].

Where PineLead fits

PineLead is an outbound lead generation tool for B2B teams. PineLead finds new prospects every day, most of them SaaS companies and startups, and scores each against your ICP criteria as a fit, a maybe for review, or a reject. It researches fitting companies and drafts a personalized first email in your voice, which you approve or send automatically with Auto-Approve. Sending happens from your own connected mailbox within a daily limit, which protects Sender Reputation. Pricing is credit-based, starting with 100 free credits that never expire. As with any channel, measure it by replies and meetings, not by the number of prospects found [2].
