A lead generation agency for businesses that sell appointments, not baskets
GrowthLine is a lead generation agency for UK service businesses: we build and run the Google Ads campaigns, design the landing pages they point at, and track every enquiry back to a cost per lead.
A lead generation agency's job is to produce enquiries — calls, quote requests, booked appointments — at a cost that leaves margin in the job.
We do it with paid search only, for businesses that sell appointments and quotes rather than online baskets, and we never buy or resell lead data.
What the lead generation service includes
| Campaign build | Keyword mapping, match types, negatives and ad copy in a Google Ads account you own — never ours. |
|---|---|
| Landing pages | A dedicated page per service or offer — see landing page design. |
| Tracking | Conversion tracking wired to forms and calls before spend scales, so cost per lead is measured, not estimated. |
| Management | Ongoing search-term, bid and budget work — the discipline documented on PPC management. |
| Reporting | Cost per lead by source, in plain numbers — reported monthly. |

How we measure cost per lead
Cost per lead is reported from the client's own conversion tracking, not platform estimates; leads are counted when a form or call fires, reconciled against the client's records.
Who this is for — and who it isn't
For
UK service businesses selling appointments, quotes and consultations — trades, professional services, clinics — UK-wide, London included. B2B lead generation is included where the buyer books a call, and we run it as a b2b lead generation agency alongside consumer-facing work.
And every sector on our industries page.
Not for
Ecommerce — no ecommerce service exists anywhere on this site, and the sitemap is checkable. Nor is it for anyone shopping for bought lead lists or an outbound lead generation agency running cold email or data resale — unlike lead generation companies that resell data, we only generate leads from your own ads on your own pages.
What it costs
Fee models in this market vary — flat retainer, percentage of spend, pay-per-lead or commission based lead generation — and most agencies, including most that call themselves a lead generation marketing agency, publish none of them. GrowthLine publishes its fees: see PPC management pricing. Media spend is paid to Google directly and is never marked up.
Lead generation agency FAQs
What is PPC lead generation?
PPC lead generation is paid advertising — usually Google Ads — that sends people already searching for your service to a landing page built to turn the visit into an enquiry: a call, a form fill or a booked appointment. You pay per click, so the discipline is matching search intent to the page and tracking every enquiry back to the keyword that produced it. It is how service businesses buy pipeline without buying data.
What are the 4 laws of lead generation?
The four laws come from US property-sales training: build a database, feed it every day, communicate with it systematically, and service every lead that comes in. The phrasing is salesy but the logic holds for paid search — generate enquiries consistently, respond fast, follow up on a system, and know what each lead cost. We handle the generating and the measuring; the responding stays with you.
What is the 5 minute rule for leads?
It is the principle that a new lead should be contacted within five minutes of enquiring, because the chance of reaching someone falls away sharply as the minutes pass — they are still at their desk, still in the mindset, and often still comparing suppliers. We wire forms and call tracking so enquiries reach you the moment they happen; what the rule then demands is operational, and it sits on your side: someone picks up the phone quickly.
Is lead generation illegal?
No — generating enquiries from your own advertising is ordinary marketing. The question usually comes from the bought-list end of the industry: reselling consumer data without proper consent can breach UK GDPR and PECR, which is why lead brokers have a reputation problem. We never buy, sell or share lead data. Every lead we generate comes from your ads, lands on your pages and belongs to you.
How much does lead generation cost in the UK?
There is no single UK number worth quoting: cost per lead depends on your industry's click prices, your conversion rate and your offer, and it varies by an order of magnitude between, say, a plumber and a commercial law firm. Most published benchmark tables are US-derived or unsourced, which is why we have not printed one here. Our guide to cost per lead benchmarks by UK industry sets out what is reliably known and how to estimate your own figure.
How much should you pay for lead generation?
Work backwards from the value of a job: what a new customer is worth, what share of enquiries you convert, and therefore the most a lead can cost before the maths stops working. That ceiling — your allowable cost per lead — is a better guide than any agency's rate card. Fee models vary across the market (flat retainer, percentage of spend, pay per lead or commission based); ours are published on the pricing page so you can do that arithmetic before you ever talk to us.
