How do I increase my eCPM or how do I achieve a high eCPM on my ADX account? Every publisher chasing AdX revenue eventually asks the same question: why is my eCPM low while someone else with similar traffic is pulling in three times as much? The answer is rarely luck. It's a combination of traffic quality, ad placement strategy, and technical setup working together. Here's what actually moves the needle.
Traffic Source Matters More Than You Think
AdX rewards advertiser demand, and advertiser demand follows buyer intent. Traffic from countries like the US, UK, Canada, and Australia commands far higher eCPMs than traffic from lower-tier geos, simply because more advertisers are bidding for those eyeballs.
If you're running arbitrage campaigns, this means your ad spend on platforms like Meta or TikTok should be laser-focused on Tier 1 geos even if the cost per click is higher. A $0.03 click from a US user monetizing at a $15 eCPM beats a $0.005 click from a geo where AdX pays $1.
Beyond geography, the source of the click itself matters. In everyway, paid traffic does better in terms of eCPM than organic traffic. While organic traffic only requires your time and effort, paid traffic requires yours time, effort and money which will definitely return more.
Which traffic source actually gives higher eCPM? The answer is simply "
TikTok". Overtime, Google algorithm has adjusted to accept TikTok traffic unlike what t was when the trend started newly. While it is still a risky venture, many publishers have taken advantage of the traffic source to scale up their revenue by over 50%.
Getting high eCPM on Facebook is also very much possible but sometimes CPC could be high.
FOR YOU:
Ad Placement Is a Science, Not a Guess
Where you put your ad units directly affects viewability, and viewability is one of the biggest levers AdX uses to decide how much an advertiser is willing to pay. A banner buried below the fold that nobody scrolls to is worthless no matter how well-optimized your header bidding setup is.
The anchor ad unit, sticky to the bottom of the screen, consistently performs well because it stays in view regardless of scroll position. Interstitials placed at natural transition points, like after a user finishes reading an article section or navigates to a new page, also perform strongly because they command full attention without feeling like an ambush.
The mistake most publishers make is stacking too many units on one page. This lowers viewability for every unit and can even trigger AdX policy flags for excessive ad density.
A good rule of thumb is to think about ad density relative to content. If your page feels like an ad farm with content put in between, you're leaving money on the table and risking a policy strike.
Here are the best ad placements which I use to gain high eCPM on my account:
- Header Ad (Before post)
- After Paragraph 1
- Anchor Ad
- Interstitial Ad (Most cases I choose top anchor)
And of you remove the "After Paragraph 1" ad unit, you might even get higher eCPM but you might also be leaving some money on the table as you would lose all the impressions which comes from that particular ad unit.
Fix Your Technical Setup Before Blaming Your Traffic
A shocking number of publishers lose eCPM to technical issues they don't even know exist. Lazy loading is one of the most underrated tools here. Loading ad slots only as the user scrolls toward them means Google Publisher Tags fires the request at a moment when the ad has a real chance of being viewed, which improves your viewability rate and therefore your average CPM.
Size mapping is another quiet killer. If your ad unit is requesting sizes that don't match the actual device viewport, you're either missing high-paying demand entirely or serving squished, ugly creatives that hurt user experience and indirectly hurt your session value. Take the time to map out exactly which sizes should render on mobile versus desktop and test it across a few real devices, not just Chrome DevTools.
Out-of-page formats like vignettes and rewarded ads (I usually do not recommend rewarded ads but you can give it a try) are worth testing too, especially on content-heavy sites. They tend to have less competition among publishers using them correctly, which sometimes means less relative fill pressure and stronger unit economics.
MCM Setup and Account Health
This is where Adzoya comes in as we help set up publishers' MCM for better performance and filled rate at a very low fee.
If you're running child sites under a Multiple Customer Management partner, make sure the parent-child relationship is properly configured and that ads.txt is correctly authorized across every domain. A misconfigured ads.txt file quietly kills demand because programmatic buyers won't bid on inventory they can't verify.
This is an easy thing to overlook once you're managing several sites at once, but it's one of the first things worth auditing when eCPM suddenly drops on a site that was previously performing well.
Also keep an eye on your account health inside Google Ad Manager. Policy violations, even minor ones, can suppress demand on affected inventory without an obvious warning. Check the policy center regularly rather than waiting for a revenue dip to go investigate.
Site Niche
No amount of technical optimization will make a low-value vertical outperform a high-value one. For instance, Finance, insurance, education, immigration, and legal content consistently command the highest CPMs because advertisers in those industries have high customer lifetime value and are willing to pay more to reach the right audience.
If you are using paid traffic, education and immigration tend to perform better for your audience.
If you have flexibility in what content you're producing or what traffic you're sending where, steering toward these verticals gives you a structurally higher ceiling before you've even touched your ad setup.
Test, Don't Assume
The publishers who consistently grow their eCPM are the ones who treat their ad stack like a living system, not a set-and-forget configuration. Run A/B tests on ad placement, try different lazy load thresholds, experiment with interstitial frequency capping, and actually read your AdX reports at the ad unit level instead of just the account level.
Small adjustments compound. A five percent lift here and a ten percent lift there, stacked over a few months, is the difference between an account that performs badly and one that keeps climbing.
High eCPM isn't a secret formula. It's the result of sending the right traffic to the right content, giving ads real visibility, and keeping your technical setup clean enough that Google's demand-side buyers actually trust the inventory they're bidding on.
