Selling workflow

Route every eligible impression with a clear set of rules.

Adon3 gives supply teams a direct path from inventory mapping to competitive clearing, with the controls needed to protect quality and yield.

01

Map the endpoint

Declare formats, inventory context and the supply chain so every request arrives with a legible path.

02

Set the guardrails

Apply floors, bidder permissions, blocklists, timeout windows and auction behavior for each traffic stream.

03

Invite competition

Route eligible impressions to clean demand and compare valid bids within the live auction window.

04

Tune the yield

Read fill, eCPM and win-rate by endpoint, then adjust floors and routing against actual clearing data.

Supply control room

Yield controls that stay close to the inventory.

01 · Pricing

Floor at the right level

Use endpoint-level price floors to protect value without applying one blunt rule to every impression.

02 · Demand

Choose who may compete

Open or restrict demand relationships and block buyers or categories that do not meet your policy.

03 · Auctions

Control clearing behavior

Configure first- or second-price handling and define the response window for each connection.

04 · Quality

Keep the path declared

Enforce sellers.json and schain signals alongside fraud filtering before a request enters the floor.

05 · Creative

Protect the user experience

Apply category and creative controls while supporting banner, native, video and high-impact formats.

06 · Reporting

See yield by endpoint

Track fill, clearing price, bid competition and discrepancies with request-level evidence when needed.

Correspondence · Common questions

What sellers ask before routing an endpoint.

01How does Adon3 decide which bid wins?
Every eligible impression is auctioned to competing demand in real time and clears to the highest valid bid. You choose first- or second-price handling and the response window per connection, so the clearing behaviour is explicit rather than inferred.
02How do I connect an SSP endpoint?
Declare your formats, inventory context and supply chain so each request arrives with a legible path, then set floors, bidder permissions, blocklists, timeouts and auction behaviour for that traffic stream. Adon3 speaks OpenRTB 2.5, 2.6 and 3.0, plus an XML feed for pop, push and direct link supply.
03Does Adon3 enforce sellers.json and schain?
Yes. sellers.json and schain signals are enforced alongside fraud filtering before a request reaches the floor, and the declared path travels with the transaction rather than being reconstructed afterwards.
04Can I control which buyers compete for my inventory?
You can open or restrict demand relationships per endpoint and block individual buyers or IAB categories that do not meet your policy. Creative and category controls apply on top of that.
05What reporting does a supply partner get?
Fill, clearing price, eCPM, bid competition and win rate broken out by endpoint, with request-level evidence available when a discrepancy needs investigating rather than a single blended total.
06How do I protect my floor price?
Price floors are set per endpoint rather than as one blunt sitewide rule, so you can protect value on inventory that deserves it and let the rest clear. Fill and clearing data then show whether a floor is costing more than it earns.
Connection brief

Connect supply with the rules already attached.

Onboard one endpoint, validate chain declarations and demand quality, then expand volume with floor and routing data in view.
