Who publishes what they charge
We went to 8 advertising providers and read their own pricing pages. 2 publish a rate. 6 name no figure at all — an auction, a media kit, or a sales team. Nothing here is a third-party average or an estimate: if a provider does not publish a price, this table says so rather than filling the gap in.
Every row links the page it was read from and the date it was read. Rates move, so a row older than 90 days is marked stale rather than served as current.
Small budgets; two twelve-hour slots a day
$0 for an empty slot, $1.00 floor to take a held one, $5,000 cap
Minimum: No minimum
Ours, so discount it accordingly. The rules are on the FAQ; what each slot actually settled at, and what it delivered, is published weekly on the price index.

Developers, on documentation sites
$3.00–$7.50 CPM by topic and geography
Minimum: $1,000 minimum ad buy
The only provider on this table with a full public rate card broken down by topic. The $1,000 minimum puts it out of reach of most small budgets.

Tech and developer publishers
No figure of any kind. "Contact our sales team to get set up."
Individual placements inside the marketplace do carry prices, but not before you are through the door.

Designers and developers
"Successful first-time advertisers typically start with a $5,000–$10,000 monthly investment over a 60–90 day period." Rates come from the sales team.
A spend guideline is not a rate: it tells you what they want you to commit, not what an impression costs.

Developers, by language (JavaScript Weekly and others)
Engagement is published — "net open rates of 35%-60%" — and the price is not. A media kit is offered on request.
Publishing the performance and withholding the price is the common newsletter pattern. It is the more useful half, to be fair to them.

Everyone; search intent
"Bidding amounts are ultimately up to you." No rate, no floor and no minimum spend is published.
Honest rather than evasive — an auction genuinely has no rate. What you can never see in advance is what the auction will cost you.

B2B, by job title and company
A page titled "pricing" that names no price: costs are "based on the type of activity you're paying for and the ad auction".
Widely reported as the most expensive per click of the large platforms, which is a thing you can only learn after spending.

Newsletter sponsorships, as a marketplace
Category benchmarks sit behind a download form. What is public is advice to publishers on what to charge — "2.5-5% of your subscriber count", worked through as "3,000 subscribers → ~$75–$150 per placement" — rather than a rate an advertiser can buy at.
An illustration is not a benchmark. Listed newsletters do show prices once you are inside the marketplace.

Why so few
Two different reasons, and only one of them is evasive. The large platforms run auctions, and an auction genuinely has no rate — Google saying “bidding amounts are ultimately up to you” is accurate. The smaller networks and newsletters do have a number and keep it behind a sales conversation, because a rate that is quoted per buyer can be higher for buyers who seem able to pay it.
Either way the buyer starts without the one figure they need. That is what the budget calculator exists to estimate, what the price index publishes for this board, and what this article argues about at more length.
One of the rows is ours, and it is marked. Corrections are welcome — if a provider on this list publishes a rate we missed, the row is wrong and we would rather fix it than defend it.
