Pay per lead sounds like the fairest possible arrangement: the agency builds search visibility, you pay only when a genuine enquiry arrives, and nobody buys a retainer that produces nothing. In practice the model changes who owns the asset, who defines a lead, and what happens to the traffic when the relationship ends, and those three questions decide whether the deal is a bargain or an expensive rental. Understanding the structure before you sign matters considerably more than negotiating the price per lead.
The two structures hiding behind one phrase
The first structure is performance-priced work on your own website. The agency does ordinary search work on assets you own, and instead of a flat retainer you pay an agreed amount per qualified enquiry, sometimes with a base fee underneath. When the contract ends you keep the pages, the rankings and the traffic. The second structure is lead generation from the agency's own property. The agency ranks a site it owns, generates enquiries in your category and sells them to you, sometimes exclusively and often not. That is a media purchase rather than a marketing service, and it can be perfectly rational, but you are renting demand instead of building an asset. Many buyers do not discover which of the two they bought until they try to leave.
How a lead gets defined, and why it decides the deal
The definition of a countable lead is the entire economics of the arrangement. Ask, in writing, whether a lead means any form submission, any phone call over a set duration, a call from within your service area, a call that reaches a person rather than voicemail, or an enquiry matching a stated service. Ask who arbitrates a disputed lead and how disputes are logged. Ask whether the same enquiry can be sold to a competitor, and if exclusivity is claimed, how it is verified. Ask what happens to a duplicate when the same person calls twice in a week. Every one of these has a defensible answer, but a vendor unwilling to write them down has already told you how disputes will go.
Where pay per lead genuinely works
The model fits categories with high transaction value, clear service definitions and a phone-first buying pattern, which is why it is most established in home services, legal work and certain medical niches. A roofing company or an emergency plumber can price a lead against a known close rate and an average job value, so a fixed cost per lead is a rational purchase. It fits badly where the sales cycle is long, where the buying unit is a committee, or where lead quality varies enormously by segment, because the agency optimises for the counted event rather than for revenue. If your average deal takes months to close, per-lead pricing will reward a volume of enquiries your sales team cannot use.
What to settle before signing
Establish asset ownership first: whose domain, whose pages, whose analytics, and what you keep on exit. If the work happens on your site, agree that all published content and every account remain yours, and grant read access to Search Console during the term rather than write access, which is the level Google's own hiring guidance recommends while a provider is auditing. Ask how the agency generates the traffic, because performance pricing creates pressure towards shortcuts and Google's spam policies apply to your site regardless of who published the pages. Finally, model the arithmetic at three volumes, low, expected and high, since per-lead pricing that looks cheap at fifty enquiries a month can be far worse than a retainer at three hundred.
Questions people ask about seo pay per lead
Is pay per lead cheaper than a retainer?
Sometimes at low volume and rarely at high volume. Run the arithmetic at several monthly lead counts before choosing. The other consideration is what you own at the end, since a retainer usually builds an asset you keep and a lead purchase generally does not.
How do I know the leads are exclusive?
Ask how exclusivity is enforced and verified, and get the answer in writing. If leads come from a property the vendor owns, ask whether the same enquiry form serves other clients in adjacent areas. Unverifiable exclusivity should be priced as though it does not exist.
Who owns the website and the rankings?
It depends entirely on the structure, which is why it is the first question to ask. Performance-priced work on your own domain leaves you with the asset. Leads bought from a vendor's property leave you with nothing when the contract ends, which is a legitimate trade if you knew you were making it.
What are the warning signs in a pay-per-lead pitch?
A refusal to define a countable lead in writing, no dispute process, vague answers about where the traffic comes from, and any guarantee of rankings, which Google says nobody can provide. Add pressure to sign a long term before a short trial period.
