What the sponsor database tracks
The brands running in the newsletters we monitor, with the ads they ran and when they ran them.
Which newsletters each sponsor buys across, so you can see the shape of a category rather than one title at a time.
The audience behind each placement, so a sponsor’s spending pattern is legible rather than anecdotal.
Repeat bookings are the honest signal. A sponsor returning to the same newsletter says more than any rate card.
Which categories are spending more this quarter and which have gone quiet, so timing is a decision rather than a guess.
New sponsorships surface as we spot them, rather than landing in a report at the end of the month.

The catch
A marketplace only works when both sides can price and plan with the same information. We are paid a commission when a booking happens — so members who know the market are the business model, not a cost to it. That is why Bellwether is free, and why it stays free.
Questions
Yes. It is free for every member of the marketplace, publisher or sponsor, with no trial window and no seat count. Comparable sponsor-intelligence tools charge in the region of forty to two hundred dollars a month.
Because a marketplace only works when both sides can price and plan with the same information. We make money on commission when a booking happens, so better-informed members are the business model rather than a cost to it.
We monitor a set of newsletters and record the sponsorships that run in them. It is observed placement data — what actually ran, and when — not estimates modelled from traffic.
No. Bellwether comes with any account. Publishers tend to use it to decide who to pitch and what to charge; sponsors use it to check a newsletter’s history before booking.
No, and we would rather say so. Bellwether covers the newsletters we monitor, and that set grows over time. It is a real sample of the market, not a census of it.
Seeing which sponsors already buy in your category, how often they return and how much reach they are buying gives you a market reference point — instead of setting a rate from scratch and hoping.
Bellwether comes with every SponsorSheep account, whether you are listing inventory or buying it. It takes about five minutes to set up.
