How ad networks pay publishers: CPM, revenue share and payment terms

25 October 2026, 4 min read

Many website owners join an ad network and then wonder how the money actually reaches them. Words like CPM, revenue share and net 30 can sound confusing at first. This article explains the usual payment path, the main pricing models and the terms you should read before you connect your site or app.

Where the money comes from

An advertiser sets a budget and pays the ad network. The network places ads on publisher sites and apps. When the ads run, the network records what happened, takes its share and pays the publisher the rest. The exact steps differ from company to company, but the logic is usually the same.

Notice that the publisher is often paid after the advertiser has paid the network. So your payment depends on a chain of reports, invoices and checks. That chain takes time, and this is why payment terms exist.

How the advertiser pays: CPM, CPC and CPA

Advertisers buy in different ways, and this changes what your traffic is worth. CPM means cost per mille, the price for 1,000 impressions. An impression is one time an ad is shown. CPC means cost per click, so the advertiser pays only when someone clicks. CPA means cost per action, so the advertiser pays when a person completes a set step, such as signing up.

Imagine an advertiser pays 2 dollars for every 1,000 impressions. For example, if your pages show 500 of those impressions, the gross value is 1 dollar before any share is taken. Real prices change with audience, ad format, country and demand, so never treat a simple example as a forecast.

• CPM: income follows the number of ads shown, so it is usually the steadiest model.
• CPC: income follows clicks, so it can swing a lot from day to day.
• CPA: income follows later actions, so it is often the slowest and hardest to predict.

What revenue share means

Revenue share means the network and the publisher split the money earned from your ad space. Imagine the advertiser pays 100 units for your impressions, and the agreed split is 70 for you and 30 for the network. For example, you would receive 70 units. The network's part pays for sales work, technology, support and the risk of non-payment. These numbers are only a hypothetical illustration.

Ask two questions. First, what money does the split apply to: the full advertiser payment, or the amount left after other fees? Second, is the share fixed, or does it change by ad format or volume? Get the answers in writing. Also remember that a higher share does not always mean higher earnings, because a network with a smaller share may bring stronger demand.

Some deals work differently. The network pays a fixed rate to the publisher, whatever the advertiser paid. This is simpler for you, but the network keeps the margin and carries the price risk, so the rate may be lower in good periods.

Payment terms to read carefully

Payment terms say when and how you get paid. They matter as much as the price. Look for the following items in your agreement.

Imagine the payment cycle is monthly and the term is net 30, counted from the end of the month. For example, earnings from the first day of a month could reach you roughly two months later. Plan your cash flow with that delay in mind.

Taxes, invoices and withholding rules differ by country. Check your local rules or ask a qualified adviser before you decide how to receive payments.

• Payment cycle: how often the network closes a period, such as monthly.
• Net days: net 30 means payment is due 30 days after a set date. Check which date counts.
• Minimum payout threshold: if your balance is below it, the money usually rolls over to the next period.
• Payment method and currency: ask about bank fees and the exchange rate used.
• Rules for holding or reversing payments: ask when and why this can happen.

Why reports and payments can differ

Your own tools and the network's reports will rarely match exactly. Counting happens at different moments. A visitor may leave before an ad loads. An ad blocker may stop one system from counting. Two systems may also define a viewed ad in different ways. Small gaps are normal. Large or growing gaps deserve a polite conversation with the network.

Invalid traffic is another reason. This means views or clicks that come from bots, accidents or tricks, and not from real interest. Networks often remove it, sometimes after the first report. So the number on your dashboard today can change later. Never click your own ads or ask friends to click them. It harms advertisers and can lead to lost earnings or a closed account.

Questions to ask before you join

Also check the trust signals. ads.txt is a public file on your site that lists which companies may sell your ad space. sellers.json is a public file where companies list who they sell for. Together they help buyers trust the inventory and help you confirm that you are listed correctly. If a network asks you to add lines to ads.txt, that is normal. Check that the lines match what you agreed.

Before you sign, write down the answers to these questions.

• What is the revenue share or fixed rate, and what does it apply to?
• What are the payment cycle, net days and minimum payout?
• How are invalid traffic adjustments explained and reported?
• Can I see reports by day, country and ad format?
• What happens to my balance if I leave the network?

Wrap-up

Money from ads is simple in idea but full of small rules. Before you join a network, put the rate, the revenue share, the payment cycle and the minimum payout in one short note, and ask the network to confirm each line in writing.
