CPM is one of the most popular pricing models in online advertising, and it’s one of the best ways to achieve high volume at a low, predictable cost.
This guide from the RichAds ad network team uncovers top CPM traffic sources and how to buy this traffic cheaply.
What is CPM traffic?
CPM stands for Cost Per Mille (cost per thousand impressions). So, with CPM traffic, you pay based on the number of times your ad is shown, not the number of clicks or conversions it gets.
Every time your ad loads on a page, in an app, or in a video player, it counts as one impression. Once you hit 1,000 impressions, you’ve paid a single CPM.
The formula is simple:
CPM = (Total campaign cost ÷ Total impressions) × 1,000
For example, if you spend $50 and your ad is shown 100,000 times, your CPM is $0.50.
CPM vs. CPC vs. CPA — quick comparison
CPM is different from CPC (cost per click), where you only pay when someone clicks, and CPA (cost per action), where you only pay for a completed action like a sale or a sign-up.
With CPM traffic, you pay for exposure. What happens after the impression — a click, a sale, a bounce — is on you to optimize.
| Model | You pay for | Best for | Risk level |
| CPM | 1,000 impressions | Brand awareness, scale, testing new GEOs | Low cost, but no guaranteed clicks |
| CPC | Each click | Time-sensitive offers, lead generation | Medium — you pay for interest, but real actions can cost more |
| CPA | Each completed action | Bottom-of-funnel offers with proven GEO+format combinations | High reward, but unpredictable for new campaigns |
Most experienced affiliates don’t pick one model and stick with it forever. They use CPM traffic to test angles and scale volume cheaply, then once a funnel is proven, they lean on CPC or CPA, paying only for results.

Why affiliates buy CPM traffic
CPM traffic provides maximum flexibility. Because you’re paying for exposure rather than a guaranteed outcome, you keep full control over how that exposure turns into clicks and conversions. You also get many other advantages:
- Low cost per unit. CPM traffic is usually the cheapest way to buy volume because you’re not paying more for guaranteed clicks.
- Fast scale. You can cover a large audience quickly, which is useful for time-sensitive offers like Sports Betting during a big event.
- Precise optimization. You control CTR and conversion rate through your own creatives and landing pages, instead of paying a fixed price per click regardless of ad quality.
- Easy campaign math. If you already know your CTR and conversion rate from past campaigns, CPM lets you calculate your real cost per click or per sale in advance and buy traffic on your own terms.
However, the trade-off is more complex hands-on optimization. Nobody needs cheap CPM traffic that doesn’t convert, so tracking, automation, whitelists, and premium sources are your best friends.
Top CPM traffic sources
CPM traffic comes from various ad formats, including pop ads, direct click, video ads, and others. Let’s review these formats closely:
1. Pop ads
Pop ads, mostly popunders, open in a new browser tab or window behind the current page. They’re among the highest-volume CPM traffic sources available, and one of the most popular sources of cheap website traffic.
At RichAds, pop ads run on CPM starting from $0.5. This format works especially well for Gambling, Betting, Sweepstakes, Dating, and Nutra offers.
Because pop ads show a full page rather than a small banner, they give you room to explain the offer in more detail. You also don’t need any creatives – only a prelander and landing page. However, we always recommend testing different landings and pre-landers to find the winners.
2. Pre-roll video ads
Pre-roll ads play before the main video on streaming and video platforms, similar to what you’d see on YouTube. The viewer has to watch for a few seconds (before they can skip) or the full ad to the end.
Video has one of the highest click-through rates of any ad format, largely because the ad sits inside the player where attention is already focused on the screen.
Pre-roll CPM is also lower than for popunders — at RichAds, prices start at $0.05. The traffic comes from top Tier-1, Tier-2, and Tier-3 countries, so you can scale your campaign across many GEOs.
Pre-roll advertising works especially well for Gambling, Betting, and Dating, where video demonstrates the product better and drives emotional response.
3. Direct click (domain) ads
Direct click ads send users straight to your landing page without showing a banner or creative first. It’s one of the simplest CPM traffic sources to set up, since the only thing you need is a landing page and an ad network with parked domains.
Domain ad CPM at RichAds starts from $1.5. Top verticals for direct click traffic include Gambling, Betting, E-commerce, Sweepstakes, and Finance.
Since optimization relies entirely on the placement and GEO rather than a creative, testing multiple landing pages matters the most.
4. Telegram ads
Telegram advertising uses a mix of CPC and CPM, depending on the format. At the RichAds ad network, five options work on the CPM model:
- Embedded banner. A simple static banner placed inside the Telegram Mini App interface is the cheapest CPM traffic source on Telegram. CPM starts from $0.4.
- Interstitial banner. It’s a full-screen static image, shown between app screens. CPM price starts from $1.5.
- Interstitial video. An interactive format, showing full-screen video with a close button. CPM starts from $3.
- Ads in Telegram bots. The ad looks like a message in the chat with a bot. CPM prices start from $3.8.
- Playable ads. It’s an interactive demo to engage and warm up the audience. Price starts from $3 CPM.

If you launch a CPM campaign at RichAds, the process is fast and straightforward:
- Choose your CPM traffic source.
Pop ads for maximum traffic volume, in-stream video for Gambling or Betting offers, direct click for fast conversions, and Telegram Mini App formats for capturing social media audiences.
- Upload creatives (if needed).
For popunder and direct click ads, you only need to add a landing page URL. For pre-roll and Telegram formats, prepare multiple creative variations to A/B test.
- Set up targeting.
Select GEO, device type, OS, browser, language, and connection type. Start with broad settings and narrow down when you have specific data.
- Set your CPM bid.
Check the platform’s minimum and recommended bids for your GEO and format, and bid a bit higher than the recommended level. CPM traffic is cheap, but bidding too low gives low quality or no traffic at all.
- Set a daily test budget.
Run a controlled test with a daily budget of around $100. When you have enough impressions to judge performance, you can optimize the budget.
- Connect a tracker.
Link a third-party tracker to see CTR, conversions, and cost per result by source, GEO, and device. RichAds ad network works with all major affiliate trackers.
- Optimize.
After the test period, cut sources with poor CTR and no conversions, and shift budget to your top performers. Use whitelists, Micro Bidding, and available automation tools like Performance Mode, Optimizer, CPA Goal, and Automation Rules.
Once your campaign delivers consistent results, you can increase your bid and daily budget to make more profits. We recommend testing new creatives continuously and expanding into new GEOs to scale in ROI.

FAQ on CPM traffic
CPM stands for cost per mille — “mille” meaning thousand. So CPM traffic is ad traffic you pay for by the 1,000 times your ad is shown. In other words, you pay for impressions.
CPM traffic comes from various ad formats that work on the CPM pricing model. The most popular are pop, video, direct click, and Telegram ads.
CPM pricing is the amount you pay for 1,000 impressions. The formula is: CPM = (total cost ÷ total impressions) × 1,000. If you spend $50 and get 100,000 impressions, your CPM is $0.50.
The network delivers traffic at or near the price you’re bidding, depending on demand for the GEO, device, and placement you’re targeting. At the RichAds ad network, CPM prices start from $0.05.
You can buy CPM traffic from ad networks that support CPM pricing. For example, RichAds lets you buy it across pop, pre-roll video, Telegram ads, and direct click formats.
You sign up, deposit funds, choose a CPM traffic source, set your targeting and bid, and the network starts delivering you traffic.
The choice depends on the offer. Pop ads are best for high-volume, low-cost testing across Gambling, Betting, and Sweepstakes. Pre-roll video works well when you need to show the product in action or communicate emotions, like with Dating and iGaming offers. Telegram ads reach a younger, mobile-first audience through Mini Apps and bots. Direct click is the simplest to set up for E-commerce offers since it skips the creative step and is built on intent.
Some ad networks like RichAds provide all four formats, so you can test them simultaneously and choose what suits your offer best.
Yes, CPM traffic is one of the most popular and effective sources for affiliate marketing. It requires more active optimization than CPA traffic, since you’re paying for exposure rather than results. However, it’s cheap and versatile, working for various offers and GEOs.
