Choose publishers and channels

Browse the channels you can buy, read their trust badges and details, then start a line item on them or ask a publisher for a deal.

Inventory lists the channels you can buy. Use it to pick where a line item runs, or to find a publisher to ask for a deal. If you pick nothing, a line item can run on any channel that passes its other targeting.

Steps

  1. Open Inventory.
  2. Search by publisher, channel or category, and narrow by platform, country, language, audience type or what can be targeted.
  3. Tick a whole publisher to include all its channels, or tick single channels.
  4. Select Create line item for these. A new line item opens with your picks already chosen.
  5. To ask for private terms instead, pick channels of a single publisher and select Request a deal.

Reading a channel

BadgeMeaning
Authorized sellerThe app developer's website lists LtvAdx in its app-ads.txt file and LtvAdx matched that website to the app's store listing, or LtvAdx confirmed it by hand. A channel whose check has just stopped passing keeps this badge for a short time.
Verification pendingThe channel is in its grace period and the check is not passing yet.
Not verifiedNo verified line was found.
ServingA valid ad ran on the channel in the last 14 days.
Ad requests, no recent adsThe channel is sending requests but no ad has played lately.
No recent trafficNo ad requests in the last 14 days. The publisher's tag may not be live.

Select Details on a channel for its inventory card: what the publisher reports about its audience and what LtvAdx has measured. Treat reported figures as the publisher's claim.

Verification is a trust signal about who is selling. It is reported, not enforced, today: a channel that is not verified still receives your ads, so check the badge before you rely on a channel. The note above the list says which applies. If LtvAdx turns enforcement on, channels that are not verified take only their publisher's own campaigns, and you can no longer pick them for a line item.

Authorized sellers only hides channels that are not verified. It is ticked when the page opens.

How picks work on a line item

  • Publishers, channels and channel groups you pick add together: a channel qualifies if its publisher, the channel itself or one of its groups is picked.
  • With nothing picked, the line item is open to all channels on your side of the test and live line. Test accounts and live accounts never mix.
  • Blocks set on the campaign always win over picks.
  • Picks are checked when you save, and again on every request. A channel that is not approved, or whose publisher blocks your brand domain or category, will not serve you. The delivery check on the line item tells you which.

If something goes wrong

  • No channels match. Clear a filter, or untick Authorized sellers only to see channels still being checked.
  • A channel you picked shows as "Removed". It is no longer listed. Take it out of the line item.
  • A publisher blocks your advertiser or category: verify your brand and declare honest categories in Brand verification, then check the line item again.
