2,510 sellers tracked, across 126 markets.
What this is
Web advertising is the biggest and oldest channel tracked here: display banners, native placements and sponsored content sold on a publisher's own pages. A publisher often sells it two ways at once — a sales team quoting a rate card or a negotiated deal, and the same inventory auctioned programmatically through an ad exchange the moment a page loads. A programmatic buy is priced per thousand impressions (CPM) and settles by auction; a direct deal is more often a flat rate, a rate card, or a negotiated sponsorship for a fixed placement or period.

Questions
Is web advertising always programmatic?
No. A publisher's ads.txt names the exchanges it auctions through, but the same site can sell a homepage takeover or a newsletter-style sponsorship directly, off a rate card or by negotiation — this directory tracks both.
What does a CPM actually buy?
A cost per thousand impressions — the standard unit for programmatic and many direct web placements alike. A $10 CPM on a page with 500,000 monthly views is a very different budget from the same CPM on a page with 5,000.
Can I buy without a minimum spend?
Some sellers state no minimum at all; others set a spend floor that can run into five figures. The directory records a stated minimum per seller where one is published — filter by budget in the directory rather than assuming a figure here.
