What you will leave with

A commercially checked referral or listing test with clear attribution and quality rules.

These channels are often grouped together, but the payment models differ. A directory may charge for a listing; a lead supplier may charge for an enquiry; an affiliate may receive commission when a booking qualifies. A comparison platform may charge for clicks or another agreed outcome. Know exactly what you are buying.

They are not automatically low risk because payment is linked to performance. Duplicate leads, cancellations, poor fit and commissions on customers who already intended to book can erode value. Start with a small agreement you can understand and reconcile.

Before you start

Who this suits

Businesses with sufficient margin, reliable tracking and a product suited to a specialist partner.

Have these ready

  • A clear retained-margin calculation
  • Written lead or booking definitions
  • Ability to reconcile referrals with actual outcomes

Understand what the fee buys

Each model requires a different quality check.

Example Travel

Worked commercial example

1A referral fee must fit the booking’s contribution

Compare the proposed charge with retained contribution, and confirm what happens if the booking changes or cancels.

2Contribution before acquisition

£300 per suitable booking in this planning example.

Fee per validated booking

£90 leaves £210 before remaining overheads and profit.

If charged on holiday value

10% of a £3,000 holiday is £300: the entire contribution in this example.

Written terms to check

Payment trigger, duplicates, attribution period and cancellation credits.

  1. 1
    Define the basis first

    The title keeps attention on contribution, which is different from the total holiday price.

  2. 2
    Show both calculations

    The same-looking fee can have a very different effect depending on what it is charged against.

  3. 3
    Turn the arithmetic into a decision

    Do not approve the trial until the payment trigger and adjustment rules are understood.

Put it into practice

Your step-by-step guide

  1. Choose the model that matches your product

    Identify where your customers genuinely compare or seek recommendations. A niche wedding directory, specialist travel publisher or relevant membership organisation may be more suitable than a general listing site. Distinguish a link that sends visitors to your website from a lead delivered directly to your inbox. If the task is website growth, report the latter as an enquiry source, not website traffic. Avoid buying listings solely because a salesperson promises search rankings.

  2. Check who can actually participate

    Read the platform’s eligibility and technical requirements. Travel comparison and metasearch often require accurate prices, availability, suitable booking links and commercial onboarding. Do not assume that having a travel website gives access to every hotel or flight advertising format. Google hotel ads, for example, require room price and availability data through a feed or integration partner. Free hotel booking links are a separate non-paid format with their own participation requirements; they are not a generic free listing for every agent.

  3. Work backwards from retained value

    Calculate what the business keeps after supplier cost and relevant variable costs, then decide what it can afford to pay for an introduction. Clarify whether commission is based on total booking value, your commission, margin or a fixed fee. Include platform, setup and management charges. Consider cancellations, refunds and chargebacks. A percentage that looks small against the holiday price can be large against the amount the agent actually retains.

  4. Define quality and payment rules

    For paid leads, agree what makes an enquiry valid, whether it is exclusive, how many businesses receive it and how duplicates or unusable contacts are credited. For affiliates, define attribution period, validation, cancellation treatment and payment timing. State whether brand bidding, voucher promotion or incentives are allowed. Require appropriate disclosure and lawful handling of personal data. An agreement to send leads should explain what the traveller was told and what contact they requested.

  5. Build the referral journey and test it

    Prepare a relevant page and approved descriptions or creative. Use partner identifiers without placing personal data in URLs. Test the click, enquiry and booking recording process, including any separate booking system. Confirm how a valid outcome will be reconciled and disputes resolved. If tracking uses advertising storage or access technologies, apply the relevant consent controls. Never accept a system’s commission total without checking that it corresponds to the agreed outcomes.

  6. Start with a limited commercial commitment

    Set the test period, maximum spend or maximum volume, and the process for stopping further referrals. Review any automatic renewal or minimum-term clause before agreeing. Check the live listing for accuracy, links and disclosure. Assign a person to respond promptly; a paid lead can lose value while waiting. If several partners send the same enquiry, deduplicate it in the lead log rather than counting each introduction as a new customer.

  7. Reconcile and decide whether to continue

    Compare partner reports with qualified enquiries, validated bookings and retained value. Track the time needed to service unsuitable requests. Look for evidence that the partner introduces new demand rather than simply appearing at the end of an existing customer’s journey. Pause or renegotiate if quality, data handling or commercial terms are wrong. A directory with little traffic may still have a legitimate membership purpose, but that is a different reason to pay than proven lead generation.

See it in action

Checking a specialist directory offer

Illustrative commercial calculation; replace every figure with your own.

A business estimates £300 retained contribution before acquisition from a suitable booking. A proposed referral fee is £90 per validated booking, leaving £210 before remaining overheads and profit. If the fee were instead 10% of a £3,000 holiday, it would consume the entire £300. The same headline percentage can therefore mean very different economics. The team confirms cancellation and attribution terms before a limited test.

Avoid these common mistakes

  • Confusing holiday value with your earnings: calculate retained contribution.
  • Assuming all metasearch formats accept every agent: check eligibility.
  • Paying for shared leads as if exclusive: read the terms.
  • Counting partner claims as new demand: reconcile actual customers.

Measure what matters

Cost per valid enquiry

Include fees and remove agreed invalid or duplicate records.

Validated booking contribution

Subtract acquisition costs from retained value after cancellations.

New-customer contribution

Investigate whether the partner brings genuinely additional business.

Keep it manageable

Your next action

Ask one prospective partner for its payment, validity, attribution and cancellation rules in writing.
