A supplier who owns the consumer brand controls quality end to end. One who does not passes on whatever came through the door.
Aggregator supply is not worse because aggregators are careless. It is worse because of what the model requires them to do, and the requirements are visible in the product.
Three things, and each has a downstream consequence for the buyer.
| Requirement | Why the model needs it | What it does to you |
|---|---|---|
| Buy enquiries from sources it does not control | Volume at a price that leaves margin | Quality is bounded by the worst source |
| Sell records more than once | Margin per record is thin | Contact becomes a race decided in minutes |
| Keep verification light | Every gate reduces sellable volume | More records that reach nobody |
None of that requires bad intent. It is what the business model looks like when it is working as designed.
Because an aggregator buying from several networks receives a blended stream, and the buyer receives the blend. A broker cannot select the good part of it, because the record does not say which source it came from. That is why the presence of a source field is such a strong signal about the supplier behind it.
The structural question: When a batch goes badly, can this supplier change the page, or only change supplier? Everything else follows from the answer.
Time, which the research prices steeply. The MIT Sloan lead response study found contact odds fall by a factor of 100 between a five minute and a thirty minute response. A chain with an affiliate, an aggregator and then a broker has two handoffs to add latency to, and neither is visible on the record.
It also costs traceability. When a consumer says they never enquired, an owned-brand operator can look at their own page. An aggregator has to ask a network, which may ask a publisher, and the answer arrives after the batch is spent.
For buyers whose constraint is volume rather than capacity. A firm with a calling team and a dialler can convert a low contact rate into a viable business, and aggregators supply the volume that model needs. The economics are real for that buyer.
For a solo adviser or a small firm, the same supply consumes the binding constraint fastest for the fewest conversations.
The last question is the one that produces the most informative answer, because it asks about capability rather than intention.
A supplier that collects consumer enquiries from sources it does not own, usually affiliate networks and publishers, and resells them to brokers. Because the enquiries were created elsewhere, the aggregator controls the distribution rather than the quality, and its overall quality is bounded by its weakest source.
The model requires buying enquiries it did not create, selling records more than once to make thin margins work, and keeping verification light because every gate reduces sellable volume. Each requirement has a direct downstream effect: blended quality, a contact race decided in minutes, and more records that reach nobody.
Ask which specific sites produced your records and whether they own any of them, and ask for a live URL. An owned-brand operator answers immediately because it is their own website. Also check whether records carry a source field at all, since its absence usually means the supplier cannot populate it.
For buyers whose constraint is volume rather than calling capacity, yes. A firm with a dedicated calling team and a dialler can run a viable business on a low contact rate, and aggregators supply that volume. For a solo adviser, the same records consume the binding constraint fastest for the fewest conversations.
