Automatic on Ezoic sites

On Ezoic publisher sites, the ad revenue your traffic earns is reported back as a conversion automatically. No pixel to install.

Your conversion. Your value.

Define the event that means success and pass what it is worth, or let us supply the value. Bidding then optimizes to that number, whether it is an order, a subscriber, a lead or ad revenue.

Subscriptions

Report the trial start and the first payment as separate events, with the plan value. Confirm payments from your billing system by postback.

Questions buyers ask.

Where exactly will my ads run?

On the Ezoic publisher network: 5,000+ premium sites and apps across news, sports, tech, food, travel, entertainment and more. Reporting shows every site your ads ran on, and allow and block lists let you include or exclude specific domains.

How do you track conversions?

Add the bsads.js pixel and fire an action for purchases, sign-ups, leads or custom values, or send conversions server to server by postback. Attribution covers click-through (up to 30 days) and view-through. When your traffic lands on an Ezoic publisher page, the ad revenue it earns is reported back automatically, with no pixel.

Which conversions can I optimize to?

Any event you define: purchases, subscriptions, leads, sign-ups, pageviews, app installs or a custom event, each with the value you pass. When your traffic lands on an Ezoic publisher site, the ad revenue it earns can be the conversion value, supplied automatically. Bid to it with Target CPA or Target ROAS.

What reporting do I get?

Three views under Analytics. Real-Time Stats shows impressions, clicks, spend and conversions as they happen. Custom Reports let you choose the dimensions and metrics, such as site, device, placement or creative. Conversion Reports tie each conversion to the campaign, site and creative that drove it, with its value and click-through or view-through attribution.

Can I get my data through an API?

Yes. The Advertiser API returns your performance reports and real-time stats as JSON, so you can feed your BI tool, warehouse or client dashboards. The same API key can pause, activate and update campaigns, ad groups and creatives in bulk, and upload offline conversions by click ID. Generate a key in your dashboard under Developer > API Keys.

Which ad formats can I run?

Display, native and video. The AI creative studio generates ads in minutes, or you can bring your own. More variety helps the engine find what works, and it promotes the winners automatically.

How fast can I launch?

Create an account, set your goal and budget, add creatives and go live. You can launch your first campaign in minutes.

How is this different from buying through my DSP?

A typical open-web buy passes through a DSP, an exchange, an SSP and often a reseller before it reaches a publisher, and each hop takes a cut. bidsystem.ai buys directly on the Ezoic publisher network, so your budget goes to the placement.

768M monthly pageviews are waiting for your ad.
