Frequently Asked Questions

The best platform for lead generation depends on your industry and target audience. For B2B businesses, LinkedIn, Google Ads, and email marketing perform best. For B2C, Facebook Ads, Instagram, and TikTok are highly effective. Google Search is ideal for high-intent leads, while SEO and content marketing generate long-term organic leads.

To choose the right lead generation company, follow these steps:
  1. Define Your Goals – Know whether you need cold outreach, inbound marketing, or paid ads.
  2. Check Their Experience – Look for case studies and client testimonials.
  3. Evaluate Lead Quality – Ask about their lead qualification process.
  4. Consider Pricing – Compare cost-per-lead models vs. retainer-based services.
  5. Request a Trial or Pilot – Test their service before committing to a long-term contract.

Yes, lead generation is still highly profitable when done strategically. Businesses that use targeted marketing, automation, and AI-driven tools see higher conversion rates. The key is to focus on high-quality leads, optimise your sales funnel, and use data-driven decision-making.

The future of lead generation is driven by AI, automation, and personalisation. Key trends include:
  • AI-powered chatbots and automation for lead nurturing.
  • Hyper-personalised marketing using behavioural data.
  • Voice search and conversational marketing.
  • First-party data collection due to privacy changes.
  • Omnichannel lead generation integrating social media, email, and search.
The cost of lead generation varies based on industry and method:
  • B2B leads: £30 – £300 per lead (depending on industry).
  • B2C leads: £5 – £50 per lead.
  • Google Ads (PPC): £1 – £100 per click.
  • LinkedIn Ads: £5 – £30 per click.
  • Cold Outreach & Email Marketing: Monthly retainers from $1,000 – $10,000.
A good benchmark is ensuring your customer acquisition cost (CAC) is significantly lower than your customer lifetime value (CLV).
