Lead generation companies create consumer enquiries on behalf of businesses that want new clients. They run advertising campaigns, build landing pages and comparison websites, capture consumer details through qualifying forms, verify the information, and deliver the completed leads to their clients — typically on a pay-per-lead basis.
The Lead Generation Process
Understanding how the process works from start to finish helps you evaluate providers and set realistic expectations about the leads you receive.
Step 1: Traffic generation. The lead generation company drives consumer traffic to their web properties through paid advertising (Facebook, Instagram, Google, TikTok, YouTube), search engine optimisation, and owned content websites. A single lead gen company might operate multiple comparison sites, advice portals, and calculator tools across different financial services categories.
Step 2: Qualifying forms. When a consumer lands on one of these properties, they encounter a form designed to capture relevant details about their situation. For a mortgage lead, this might include property value, mortgage purpose, employment status, and timeline. The form serves two purposes: it captures the information you need for an informed first conversation, and it filters out consumers who are not serious enough to complete a multi-step form.
Step 3: Verification. After form submission, the consumer verifies their contact details — typically by entering a code sent to their mobile phone via SMS. This confirms the phone number is real, active, and belongs to the person who submitted the form. It also acts as a final intent check — only engaged consumers bother to complete this step.
Step 4: Delivery. The verified lead is immediately routed to the appropriate buyer based on pre-agreed criteria such as lead type, geographic area, and volume allocation. Delivery happens in real-time via CRM API, email, SMS, or a combination of methods.
Step 5: Quality assurance. Reputable providers maintain ongoing quality checks — monitoring contact rates, tracking refund requests, and adjusting their advertising and targeting to maintain lead quality over time.
The Business Model
Most lead generation companies operate on a pay-per-lead model. They bear the upfront cost of advertising and only generate revenue when they deliver a lead. This means the lead gen company absorbs the risk of poor-performing ad campaigns, low conversion rates on landing pages, and the cost of leads that fail verification.
The margin between what the company spends on advertising to generate a lead and what they charge you for that lead is how they make their money. This margin needs to be large enough to cover their technology infrastructure, staff, ongoing ad spend testing, and the cost of replacing invalid leads.
What Separates Good Providers From Bad
The lead generation industry includes excellent operators and poor ones. Here are the key differentiators:
Exclusivity. Good providers sell each lead to one buyer only. Poor providers sell the same lead to multiple buyers simultaneously, which destroys contact rates and consumer trust.
Verification. Good providers verify contact details before delivery. Poor providers deliver raw form submissions without checking whether the phone number is real or the person genuinely intended to enquire.
Transparency. Good providers are upfront about how they generate leads, what qualifying questions they ask, and what their refund rates look like. Poor providers are vague about their methods and resistant to sharing performance data.
Replacement policies. Good providers have clear, fair policies for replacing leads that do not meet specification. Poor providers make the refund process difficult or have no policy at all.
Compliance. Good providers have robust GDPR compliance processes, including documented consent, clear privacy notices, and ICO registration. Poor providers treat compliance as an afterthought.
Questions to Ask a Lead Generation Company
Before committing to a provider, ask these questions: How do you generate your leads — what platforms and methods do you use? Are your leads exclusive or shared? What verification processes do you use? What is your current refund or replacement rate? Can I see example consent language from your forms? Do you offer real-time delivery? What CRM integrations do you support? Can I start with a small test batch before committing to volume?
A confident, reputable provider will answer all of these questions clearly and willingly. Evasiveness on any of these points should raise concerns.
