How to Sell Direct Without Giving Up Your Current Ad Revenue

The assumption that stops people

Most publishers assume selling directly means replacing what they run now. Pull out the network code, put in something else, and hope the new thing earns more than the old one. Framed that way it is a genuine gamble, and a sensible person declines it.

That is not how it works.

Ad serving is a chain, not a switch

An ad server asks a series of questions in order. Is there a direct campaign that should run in this slot right now? If yes, serve it. If no, hand the slot to the next source. If that returns nothing, hand it to the one after that.

This is called a passback, or a fallback. Your existing network becomes one link in that chain rather than being removed from it.

The request only reaches the next link when the one before it has nothing to serve.

What that means in practice

Your existing ad code goes inside the new slot as the fallback. When you have sold a placement directly, your advertiser's banner runs. When you have not, the request falls through and your existing network serves the slot at the rate it pays today.

The arithmetic is worth stating plainly. On any given impression you earn either your direct rate, which you set above the network's, or the network's own rate. The one change to plan for is the Advertise Here card, which by default takes one unsold view in ten to find your next advertiser, and which you can switch off.

The one real cost

The honest caveat is that a direct campaign taking a slot means the network does not get that impression. So network revenue does go down as direct revenue goes up. That is not a loss, it is a substitution, and it is a good one as long as your direct rate is higher than your network eCPM.

Which is why knowing your eCPM before you set direct prices matters. It is your floor.

What to check before you start

Check your current network's terms on running alongside other advertising. Most permit it, but the specifics are worth reading rather than assuming, particularly around how many ads may appear on a page.

Check that your fallback actually fires by leaving a slot unsold and confirming your existing ads still appear. Do this before you sell anything, not after.

And keep your eCPM calculation somewhere you can find it. It is the number that tells you whether any given direct deal is worth taking.
