Module 2: Designing Google Ads Around Lead Quality
Module 2 · Lesson 1
A form submission is not automatically a good lead. A phone call is not automatically valuable. Lead quality depends on what happens after the conversion.
Define what a high-quality lead means for a specific business and create practical criteria that can later be fed back into Google Ads optimisation.
Conversion does not equal commercial value
Google Ads can measure actions such as form submissions, calls, bookings and enquiries. But the platform cannot automatically know whether those actions represent genuine commercial opportunities.
The central problem
Google Ads sees a conversion. Your business sees a person, company, requirement, budget and probability of becoming a customer.
Two campaigns could each generate 50 leads at £40 CPL and appear identical inside Google Ads. Yet one could produce £50,000 of profitable business while the other produces almost nothing.
The four dimensions of lead quality
Fit
Does the prospect match the type of customer the business actually wants?
Intent
Are they genuinely considering a purchase, or simply gathering information?
Ability
Do they have the budget, authority and practical ability to buy?
Probability
Based on historic data, how likely is this type of lead to become a profitable customer?
Fit: is this the right type of customer?
Fit varies enormously between businesses.
Example: commercial roofing contractor
A facilities manager requesting a quotation for a 20,000 sq ft warehouse may be highly valuable.
A homeowner asking for a repair to a garden shed may technically be a roofing enquiry, but commercially it may be worthless to that contractor.
The keyword could still have been relevant. The advert could still have been clicked. The form could still have been submitted. Yet the lead is fundamentally wrong.
Intent: how serious is the enquiry?
1Research“How does this work?”
2Exploration“What are my options?”
3Comparison“How much would you charge?”
4Purchase intent“Can you quote for this project?”
5Immediate requirement“We need this completed next month.”
High-intent leads are not always the largest opportunities, but intent is an important indicator of likely conversion into pipeline.
Ability to buy
A prospect can be perfectly interested and still be commercially unsuitable.
- Insufficient budget
- No purchasing authority
- Outside the service geography
- Requirement too small
- Requirement too large or complex
- Timing incompatible with the business
- Needs a service the advertiser does not provide
Important
Qualification criteria should reflect genuine commercial constraints, not arbitrary assumptions about who “looks” like a good prospect.

Practical challenge
Define your qualifying lead
Take one Google Ads account and write down:
- Three characteristics of an ideal lead.
- Three common reasons leads are rejected.
- The first event in the sales process that reliably indicates genuine quality.
- Whether Google Ads currently receives that information.
Knowledge check
Check your understanding
1. Which is the best definition of a high-quality lead?
2. Two campaigns have identical CPL. What should you investigate next?
3. Which is most likely to be a lead-fit criterion?
4. Why is a conversion insufficient evidence of lead quality?
A high-quality lead is not simply a conversion. It is a prospect with the right fit, intent and ability to buy — and a meaningful probability of becoming a profitable customer.
