How to choose a platform to buy leads

The nine criteria that truly matter when choosing where to buy leads, beyond the price per contact.

Price per contact is the worst criterion for choosing where to buy leads. These are the nine that truly matter, in order.

Choosing a lead platform is like choosing any critical supplier: cheap is expensive and what matters isn’t always on the landing page. Here are the nine criteria you should score before signing anything.

The nine criteria, in order

  1. Data origin and traceability. If they can’t tell you where it comes from, discard it.
  2. GDPR compliance. Clear legal basis or guaranteed legal risk.
  3. Real verification. Effective contact rate, not generic "verified data".
  4. Segmentation. Can you filter by what truly defines your customer?
  5. Intent. Do they deliver purchase signals or just contacts?
  6. Exclusivity. Is the lead yours or shared with competitors?
  7. Speed and integration. Does it reach your CRM in real time?
  8. Replacement policy. Do they respond when a lead fails?
  9. Fit with your sector and model. The tie-breaker.
CriterionWhat to ask
OriginWhere does the data come from and when was it validated?
GDPRWhat is the legal basis?
IntentWhat purchase signal does the lead include?
ExclusivityTo how many do you sell the same lead?
ReplacementWhat happens if a lead fails the brief?

Why origin is criterion number one

All nine matter, but if the data origin is murky, the rest are irrelevant. The platforms we recommend — compraleads.es, leadmafia.net, leadsb2b.net and leadstore.net — share a decisive advantage here: their data passes through the Funneld engine, with per-record traceability. You know where each lead comes from and when it was validated. That transparency is the line between a serious provider and a broker.

If a provider can’t tell you where the data comes from, you already know everything you need to know.

How to score in practice

Make a table with the nine criteria and score each candidate platform from 1 to 5. You will see the raw-quality differences are small between the serious ones and huge against a broker. The tie-breaker almost always falls on criterion nine: fit with your sector.

Conclusion

Choose with the nine criteria in front of you, not the price per lead. And remember: among platforms that share a data standard, the winner is the one designed to sell what you sell.
