Ads that pay the people who make the page.

Market One Ads is the ad network for independent websites. Publishers paste one tag and keep 70% to 75% of what advertisers pay. Advertisers reach readers by what they are reading, not by who they are.

Good advertising starts with a fair deal for both sides.

For media owners

Your readers came for your writing. We fill the space around it with ads that load late, sit still and never follow anyone home. You keep 70% from day one, 75% once you pass 50,000 sessions a month, and you see every cent per site per day.

For buyers and brands

Tell the chat your website. It reads it, writes the ads, picks the topics and sets the budget with you. Your ads run beside matching pages, and you pay for impressions people actually saw, or for clicks.

One tag. Every format. No cookies.

The Market One tag is about 9 KB of JavaScript. It reads the page’s topic, places slots where they do no harm, fills each one only as it comes into view, and counts an impression only when half the ad has been on screen for a second. It stores nothing in the reader’s browser.

What makes it better?
The parts you can check.

Seen, not served

Advertisers pay for impressions at 50% in view for one second, tab visible. Slots reserve their height, so pages keep a layout shift of zero.

Every screen

Display, native and video on desktop and phone, from one tag. Each creative is scored for the slot it lands in, so a banner never squashes into a sidebar.

Private by design

Contextual only. No cookies, no storage, no cross-site IDs; requests carry the host name and a few page keywords, never the path. Our own ads need no consent banner.

Display, native, video and mobile

Display

Banners in the sizes buyers already make: 300x250, 728x90, 320x50, 300x600 and 160x600. Each slot keeps its height before it fills, so the page never jumps.

Native

A card that takes the page’s own fonts and colours: picture, headline, one line, a button. Always marked Sponsored, with the advertiser’s domain.

Video

Plays muted, and only while on screen. A view counts after two seconds playing in view; a Sound on button hands the choice to the reader.

Mobile

On phones, one anchor bar and in-content slots below the fold. Nothing covers the article, nothing pops up.

Header bidding, managed

Every slot is sold through one auction before the page shows it. You never touch a wrapper.

  1. Our direct priceMarket One’s own campaigns bid first, ranked by effective CPM, topic match and fit.
  2. Prebid.jsOur Prebid manager asks every exchange whose IDs are filled in, all at once, with a one-second timeout and floors per format.
  3. AmazonAmazon Publisher Services bids alongside.
  4. Google Ad ManagerRuns the final auction with AdX and AdSense competing. If our line wins, our ad draws; if nothing wins, our ad still shows.

Built and tested; each exchange switches on as its account opens. Our Prebid build carries adapters for Magnite, PubMatic, Index Exchange, OpenX, TripleLift, Sovrn and Sharethrough.

The exchange

Market One speaks OpenRTB 2.6, so a demand-side platform can bid on our publishers’ pages directly.

One request per partner

Each paid impression on an approved site goes out as a bid request to every enabled DSP in parallel, each with its own deadline and rate limit.

One auction

Valid bids join our direct campaigns in the same auction, then meet Prebid and Google on the page. The best price wins, wherever it came from.

Signals buyers trust

Every site carries IAB content categories, our sellers.json and an ads.txt line; win, billing and loss notices go back to the bidder.

Safe creatives

HTML creatives render in a sandboxed frame on an origin of their own, never on the publisher’s page.

Deals and marketplaces

Private marketplace deals for one buyer, programmatic guaranteed for a fixed volume, and curated packages that group our sites by readership. Packages carry a US$1.50 floor.
